Heat stress to become greater threat to agricultural workers

The agriculture sector in Africa could lose up to 14 million jobs by 2030 due to heat stress. This was according to a new report by the International Labour Organisation titled, ‘Working on a warmer planet: The impact of heat stress on labour productivity and decent work’.
While it was expected that the general labour force in Africa would increase by 2030, some jobs could be threatened as working hours were reduced due to heat stress. The agriculture sector was expected to be one of the sectors that would be greatly affected by this.
According to the report, more than 129 million workers on the continent were employed in agriculture in 1995, accounting for more than 55% of the total workforce of around 230 million workers.
“Although these [figures] are projected to decrease in all the sub-regions by 2030, the overall figure is expected to remain relatively high, with more than 290 million workers working in agriculture by 2030, or 48% of the total workforce, which is projected to be more than 610 million workers,” the report said.
It noted, however, that given the physical nature of labour in agriculture, which was mostly undertaken outdoors and entailed direct exposure to heat, workers would be particularly affected by higher temperatures that were a result of climate change.
It was estimated that global temperatures would increase approximately 1,5°C by 2025.
These high temperatures would make some farming regions unproductive, leading to the displacement of large number of workers, as they are forced to leave rural areas in search of better prospects in cities or abroad.
The study also said that about 1,3% of the total number of working hours in Africa were lost due to heat stress in 1995, a productivity loss equivalent to more than three million full-time jobs.
As heat stress intensified, up to 2,3% of total working hours would be lost by 2030, which was the equivalent of about 14 million full‑time jobs.
The impact of such productivity losses would impact food production and result in greater poverty and food insecurity.
The report suggested that the long-term options for reducing the impact of heat stress on agriculture included promoting mechanisation and skills development policies aimed at increasing the efficiency and sustainability of food production under new climatic conditions, complemented by monitoring and awareness campaigns.

Coffee crisis brings coffee makers together

To allay the fears of coffee farmers in South America, the focus of the second conference of the Coffee Producers’ Forum would be on the current low prices of the commodity.
The conference was due to be held on 10 and 11 July in Campinas, São Paulo, Brazil.
According to Vansula Nogueira, one of the organisers of the forum, the main objective of the conference was to explore ways to improve the economic sustainability of coffee producers in the main production areas across the region.
Since the previous conference in 2017, prices of coffee had fallen substantially.
“We need to discuss alternatives to improve income for farmers,” she said.
Coffee prices on the ICE commodities exchange in New York reached a 12-year low in May this year at US86c/lb (about R26/1kg).
A statement by the forum outlined the major challenges faced by growers, such as economic sustainability, farming levels, price volatility on international markets, the increasing demand for more than 50 million bags over the next 10 to 15 years, and climate adversity.
At the 2019 conference, coffee-growing nations in the region will discuss common interest in this regard, such as the revenue generated by coffee growers, environmental issues, as well as ensuring the sustainability of the industry.
“All this so that more than 25 million families who grow beans and create the drink that satisfies the most diverse tastes around the world can keep growth and quality scaling [on track],” the statement said.
While prices had risen slightly over the past month, farmers were still concerned that this increase would be unsustainable.
Jose Marcos Magalhaes, head of the Minasul co-operative in Brazil and the country’s national coffee council, said one of the issues that needed to be addressed was the way in which crops were sold by farmers.
Magalhaes emphasised that the use of technology to “facilitate and speed up sales” needed to be discussed.
Coffee producers in some countries had also said that finding ways to control the flow of coffee from producing countries to the main consuming centres needed to be examined. However, consensus regarding this issue could not be reached as Brazil opposed the move.

Cattle production: Your calves and parasites

Question: The rainfall was exceptionally high in my area during late summer and autumn. The grazing looks good, and the cows are in a good condition, but my calves are not growing too well. What could the problem be?
Most parasites flourish under wet and warm conditions. Roundworms and tapeworms, for instance – produce a large number of eggs. These are excreted in the dung of animals and then need to hatch and develop on the grazing before they can infect cattle again. Wet, warm conditions are ideal for the survival and development of young worms on grazing.
During a wet year, the number of parasites on the grazing is much higher than usual and young animals, such as calves, are especially affected because they don’t have any resistance to round and tape worms. This means that most of the young worms ingested when the calves start to graze will attach and grow to adult worms in their intestines. And this will affect the growth of young calves severely.
In a wet year, young calves have to be dewormed at 3 and 5 months of age, because they don’t have any resistance to roundworms and tapeworms at this age. Over time, cattle build up a resistance to these specific parasites and that’s why the adult cows are still in a good condition.
Ask a veterinarian for a broad-spectrum livestock remedy that works against all the kinds of round worms as well as tape worm. Dose the calves and you’ll see better growth and improvement in condition within two weeks. If there’s no improvement, the problem needs to be discussed further with the veterinarian from which you bought the remedy.

Cattle production: Prevent injuries with good planning

By Digital team

One of the greatest constraints veterinarians find when trying to treat cattle is the lack or inadequacy of handling facilities. If it is too difficult to constrain cattle, the owner won’t be able to examine or treat sick animals in time.
The handling facilities on a cattle farm are a direct reflection of the level of management on that farm. Good handling facilities are a prerequisite for efficient and safe cattle management.
Easy handling will prevent people from shouting at and hitting cattle out of sheer frustration, which could have a severe impact on animal welfare and also result in bruising. If basic good handling facilities are in place, it would never be necessary to hit animals with sticks or whips.

CRUSH PENS

The minimum requirement, even if you only own a few head of cattle, is to have a crush pen. You must be able to handle a cow or bull without injuring the animal or yourself. If you can’t do that, it would be better not to own cattle.
The type of crush needed is determined by the type of cattle and the number of animals to be handled. The height is determined by the type of cattle.
The average height is 140 cm, but an extra horizontal pole can be added to the top of the crush to increase the height to 180 cm when working with very wild cattle.
The average inside diameter of a crush pen is normally 70 cm, but it can be larger or smaller, depending on the size of the average cow in the herd, whose weight could vary between 350 kg and 550 kg.
There’s a big difference between the basic handling facilities needed for 10 head of cattle and those needed for a group of 100 or more.
With such a basic facility you can:
  • Effectively treat a sick animal.
  • Do ongoing treatments for parasites.
  • Vaccinate animals regularly.
  • Provide supplementary licks only to those animals that need it.
All small-scale cattle owners need such a basic facility, but it’s also suitable for commercial cattle farmers at their watering points. It’s very helpful for giving emergency treatment – such as assistance with calving or treatment of a tick-borne disease such as redwater – when cattle can’t be moved over long distances to the main handling facilities.

FUNCTIONALITY

A few basic rules for effective facilities:
  • There must be holding kraals before and after the crush pen and they must be connected. Some cattle will always escape from a crush pen and you must be able to get them back if something like vaccinations is being done.
  • The entrance to the crush pen must have one straight side, otherwise it will always be difficult to get cattle to enter.
  • Gates connecting kraals must always be at the side, otherwise it will be difficult for a single person to herd cattle from one camp to the next.
These may seem like basic rules, but on more than 50% of farms I visit one or more of these rules are not followed, leading to severe difficulty in handling animals, frustration and injury to animals and people.
Easy handling will prevent people from shouting at and hitting cattle out of sheer frustration, which could have a severe impact on animal welfare and also result in bruising. If basic good handling facilities are in place, it would never be necessary to hit animals with sticks or whips.

Better results with a single-breed herd on the Highveld


After suffering the effects of a trichomoniasis outbreak in 2010, Afrikan Farms, winner of the ARC’s National Commercial Beef Producer of the Year award for 2018, decided to switch from running a mixed-breed cattle herd to a Beefmaster herd. Siyanda Sishuba reports

Based near Amersfoort, Mpumalanga, Afrikan Farms is a diversified commercial enterprise, with cattle farming as its core business. In 2000, through the Vusi Khanyile Family Trust, the Khanyile family bought farming land on auction and immediately started their operation.
About two years later, the business corporatised with the establishment of Afrikan Farms (Pty) Ltd.
The business comprises four farms, all sharing boundaries, spread over 4 709ha. They are Zwelihle (the centre of the family’s cattle farming operations), Vaalpoort, Zoetfontein and Broederstroom. The last three are used for sheep farming and as grazing land.
The management team comprises predominantly people in their 30s.
“Having diverse skills has helped us to manage the farm better,” says general manager Phakade Khanyile, the son of Vusi.
He runs the farm with cattle manager Nsika Shabalala, feedlot manager Sibongeleni Mthenjwa, COO Siphiwe Kumalo, and technical manager Thinus de Jager. The directors of the company are Vusi, Ndoni Khanyile and Mthenjwa.
Not just cattle
Afrikan Farms’ activities comprise animal husbandry, crop farming and apple production. This includes managing a commercial herd of breeding cattle, sheep farming and an experimental piggery. A cattle feedlot is a recent addition.
Eragrostis grass is grown for baling, and Kikuyu, clover and ryegrass are planted for grazing. The farms’ carrying capacity is approximately 1 MLU/2,5ha.
The enterprise has entered into a partnership with a neighbouring farm, BB Boerdery Agri Trust, to form a subsidiary company called WeGrow Farming Enterprise, mainly for community development.
This plants 1 600ha to maize (70%) and soya bean (30%), which are also used for feed production. Planting equipment is shared by both parties.
The area receives about 600mm of rainfall a year, and rainwater is harvested. Boreholes and dams are used to augment the water supply.
In 2016, Afrikan Farms introduced a feedlot and finishing system to supply abattoirs directly and thus enhance profitability. The on-farm feedlot can carry about 400 cattle at a time, and supplies mainly the Volksrust Meatco Abattoir.
According to feedlot manager Mthenjwa, the enterprise is doing well but there is room for improvement. The feeding period is 150 days, and the gain per animal is 1,8kg/day on average.
Breed type and production system
Cattle manager Shabalala explains that when the family established its commercial herd in 2003, there was a mixture of different breeds on the farm. About 70% were Red Angus type, and the herd comprised approximately 400 cows and 20 bulls.
“We started breeding with Beefmaster genetics in 2010 after the area suffered an outbreak of trichiamoniasis,” he recalls. “We had to source bulls from other farmers during that time, and decided to focus on a single breed for our herd. Cattle consultant Barry Symons advised us that Beefmasters are more suitable for the Highveld region.
The breed was chosen for its adaptability to the tough conditions, affordability of the breeding bulls, docile calves and a desired weaning weight.Farming with a uniform breed makes it easier to service the abattoirs we supply.”
Shabalala says they started replacing about 10% of the bull herd with Beefmaster bulls annually. Breeding bulls are now kept for five years to improve genetics in the herd and to minimise transmission of diseases generally, as well as the devastating effects of venereal diseases such as trichomoniasis on herd profitability.
Older bulls are sold at auctions.
“Previously, only natural mating was used, but we started implementing artificial insemination [AI] in the spring of 2014 because we wanted to push the majority of the cows to calve early. We inseminate half the herd via AI annually,” he says.
The heifer:bull ratio is 1:30. Immediately after AI is performed, the bulls are introduced into the herd to give heifers and cows that failed to conceive another chance, and to service cows and heifers that did not undergo AI.
A single breeding season
‘’Before 2014, an average of about 460 calves were born each year, and that number has doubled,’’ Shabalala says.
The cow herd is currently 1 054 head strong, and there are 60 bulls, 380 heifers and 683 calves.
The herd has a conception rate of about 85%, a calving rate of 80% and a weaning rate of 70%.“A single breeding season is best for our environment. The breeding season runs from October to December and calving occurs between July and September.
Calves are weaned around March. This programme ensures that during the calving period we have maize available, and it’s close to spring when the grass turns rich and green.
“The average intercalving period is under 400 days. In the past, the calving percentage was very low as we didn’t have enough experience of managing beef cattle. No clear records were kept,” he says.
About 80% of heifers are selected to join the main breeding herd. After being weaned and backgrounded on the veld for one month, the male calves are sent to the feedlot for four months until they are sold to an abattoir or slaughtered.
The weaning weight for calves going to feedlot is between 210kg and 220kg. The target weight when they leave the feedlot is 420kg to 450kg. The weaning weight for the young heifers is 200kg to 220kg, and they are kept on the veld for a year and mated in autumn.
Heifers need to weigh above 300kg by the time they are mated. The heifers that are not due to be part of the herd are sold to the Highveld Breeders’ Group. Afrikan Farms became a member of the Agricultural Research Council’s (ARC’s) National Beef Cattle Improvement Scheme in 2016.
Following this, it implemented performance testing and recording. Within three days of birth, calves are given identity numbers via tags and brand marks. Two of the farm’s personnel were also sent to the ARC to attend a course that focused on the use and implementation of best linear unbiased prediction (BLUP) breeding value technology for commercial farmers.
Through the course, they also acquired skills that enabled them to interpret an auction catalogue when buying stud bulls.
Winning top awards
In 2018, Afrikan Farms won the ARC National Commercial Beef Producer of the Year award. Every year, the ARC aims to recognise a commercial beef producer who participates in performance testing and has made great progress in his or her enterprise through applying performance- recording technology.
Plans for the future
Afrikan Farms sees itself as a developing commercial farming business that uses sustainable agricultural methods, such as appropriate grazing practices that promote a healthy ecology, coupled with sound business practices.
To be sustainable, it recognises that it has to continue employing these practices over the next three to five years to meet the required threshold return on the capital invested.
Afrikan Farms has also adopted a number of ecologically sensitive practices to reduce its dependence on fertilised pastures.
For example, it invests adequately in dam infrastructure to ensure water availability and supply to support the herd and supplement the limited rain in early spring and late summer.
It is also building relationships with stakeholders in the sector to help ensure its success, and is seeking to increase its transformation initiatives involving its employees and development initiatives for the local community.
It is currently expanding its cattle, sheep and high-value export crops, and is establishing a 4ha apple orchard on Zwelihle farm. Through WeGrow Farming Enterprise, the business is in the planning stages of establishing a piggery unit with 1 200 sows. The long-term plan is to farm 9 600 sows

Pig farmers seek to streamline GMO pork


Pork producers are stepping up their campaign to ease regulation of genetically engineered livestock following an executive order President Donald Trump issued earlier this month instructing federal agencies to speed up approval of new agricultural biotechnology.
The National Pork Producers Council is seeking White House intervention to reverse a Food and Drug Administration stance that genetically edited animals should be regulated like drugs and barred from entering the food chain until the modifications are shown to be safe.
The trade group wants the Department of Agriculture to be the lead oversight agency, maintaining that regulatory hurdles risk giving a competitive edge to more permissive countries, including Brazil, Argentina, Canada and China.
“We are looking for leadership from the White House to reconvene talks,” Dan Kovich, the group’s director of science and technology, told reporters June 25 on a conference call. “There are other legitimate, viable regulatory pathways.”
U.S. regulatory concerns could slow introduction of an experimental gene-editing technique to make hogs resistant to porcine reproductive and respiratory syndrome virus, Kovich said.
Trump’s June 11 executive order instructs the USDA, the FDA and the Environmental Protection Agency — all of which have jurisdiction over genetically engineered agricultural products — to review their biotechnology regulations to streamline the approval process.
Alison Van Eenennaam, an agricultural Extension specialist in animal biotechnology and genomics at the University of California, Davis, who participated in the call, said new gene-editing techniques don’t introduce genetic material from other organisms and produce similar risks to conventional breeding techniques, which aren’t regulated.
The Agriculture Department earlier this month proposed a broad overhaul of biotech rules that would exempt from regulation genetically edited farm products with traits “similar in kind” to modifications that could be produced through traditional breeding techniques.

Designed specifically for South African conditions, the NOVAP Sub-Surface Water Diffuser facilitates deep root irrigation and supplies water directly to a plant’s root system.
As no water is exposed to the soil surface, moisture loss through evaporation is dramatically reduced.
Ferdinand de Klerk, NOVAP’s brand manager, says the system was developed and patented in Cape Town by Jan Nortjé, an inventor who strives to provide practical solutions to specific problems. “His insight into technical challenges has led to the registration of various international inventions,” says De Klerk.
Development started in 2013, and the irrigation system was launched in April 2017. Trials have shown water-use reduction of as much as 70%. In a Western Cape trial on 1ha of table grapes, a total water saving of 56,8% and a yield improvement of 31,5% were recorded after the change from micro irrigation to deep root irrigation.
The NOVAP system is suitable for any type of tree or shrub, including roses and other perennial scrubs with root systems deeper than 150mm. Fruit trees, vineyards, as well as nuts and date trees respond particularly well to this type of irrigation, according to De Klerk.
Water table at root level
The system consists of a compact plastic unit installed at the optimal depth for specific crops, typically 250mm. It supplies water and liquid fertiliser at a steady rate for maximum uptake, and artificially creates an underground water table at root level.
Depending on the soil type, a hydrated bulb with a radius of up to 600mm is formed 1,2m deep. The capillary movement of water allows the moisture to rise 120mm to 150mm above the system.
(Capillary action is the ability of a liquid to flow sideways and even upwards in narrow spaces without the assistance of external forces.)
“The subsurface water diffuser is placed in such a way that the hydrated underground bulbs overlap. This causes a long, continuous water table at root level,” De Klerk explains.
Ideally, the unit is attached to a solid feed line with regulated water outlets (drippers) feeding into it.
When the pumps are switched on, water is pumped from the source, such as a dam, through the main lines to the lands. From the moment it leaves the original source, the water is never exposed to sun or wind.
“This is why 100% of the irrigation water reaches the plants’ deep root levels. At the end of an irrigation cycle, all the water drains out into the soil.
Trials have shown that the soil temperature remains constant at an average of between 18°C and 22°C,” says De Klerk.
Research has found that when the soil temperature reaches 18°C, the plant can function at an optimal transpiration rate. Transpiration, which is water evaporation mainly via the stomata, aids the uptake of nutrient-rich water from the roots, aiding growth.
Deep root irrigation also results in higher chlorophyll content. In mature vine leaves, an improvement of as much as 7,4% was recorded.
The amount of chlorophyll in a leaf contributes to its transpiration efficiency. Higher levels of chlorophyll and increased root temperature work together to improve plant transpiration and fruit development.
“Visually, the differences in foliage growth, fruit size and colouration of the grapes were immediately evident. A plant’s leaf can be described as its food-manufacturing facility.
More and larger leaves result in a well-functioning plant, which obviously results in improved yield and quality,” says De Klerk.
Improving efficiency
Deep root irrigation uses considerably less water, and in South Africa’s dry climate, this is obviously welcome. But reducing water use has two additional benefits: it helps cut electricity usage, saving money, and it results in less humidity in the plant foliage canopy due to the dry soil surface.
Ferdi van Zyl, an independent environmental scientist and consultant in microbiology, plant pathology and botany, says that water savings of 56% were recorded in a deep root irrigation field trial in a 1ha block of Scarlotta table grapes in Piketberg.
The block of grapes was converted from micro irrigation to deep root irrigation in November 2017. In the first season, water use decreased 56%. The deep root irrigated block also showed a visible improvement in general foliage and grape size, compared with other blocks.
In another trial involving a block of Sweet Joy grapes in Robertson, water usage declined by 50%. The block was planted to the grapes in September 2017 and deep root irrigation was installed in January 2018.
“During my visit in December 2018, I noticed the difference in weed growth,” recalls Van Zyl. “With surface irrigation, all seeds present have the ideal opportunity to germinate. Deep root irrigation ensures dry surface soil, resulting in less weed growth and a reduction in the cost of weed control. Moreover, with water saving of at least 50% on average, we’re also recording better foliage growth.”
Increased soil moisture with less water
In a trial in Porterville, the NOVAP system was installed in a 2ha fig orchard, and tree growth monitored. The previous double- line drip irrigation had delivered water at a rate of 13,8ℓ/h/ tree but the deep root system was set to 8ℓ/h/ tree. The trees were planted in clay-rich soil on a slope.
According to Van Zyl, despite the fact that the water supply had been cut by 40%, the soil moisture content increased from less than 40% from 300mm downward to between 60% and 70% from between 400mm and 800mm deep.
Another advantage was a significant decrease in weed growth around the trees, which also have larger leaves than the trees in the surface drip blocks.

Getting started with dairy goats: practical tips from a farmer


Three years ago, WA Hugo started farming dairy goats on 8ha just outside Lambert’s Bay. Today, he has a herd of 150 goats and produces various cheese products. Jeandré van der Walt visited him on his farm, Bettiesville, to learn more about the dos and don’ts of dairy goat farming.





“I’ve always been fond of goats. When I was young, we always had goats around and used to drink a lot of goats’ milk,” recalls WA Hugo, owner of the farm Bettiesville near Lambert’s Bay.
When the opportunity presented itself in 2016, Hugo therefore lost no time in pursuing his dream of dairy goat farming and commercial cheesemaking. He markets the cheeses under the ‘Bettie Bok’ brand.
Hugo points out, however, that starting out in dairy goat farming is not that simple: it takes careful thought and planning.



Husband and wife team WA and Lillibet Hugo.
“You need to ask yourself two questions: why am I choosing goats? And what do I want to achieve with my goat farming operation?” says Hugo.
Finding the best goat
The Bettiesville herd consists of 150 goats, with 75 ewes in milk. Hugo farms mainly Saanen goats due to their high milk yields and docile temperament. But he adds that there are a number of breeds to choose from, such as the Toggenburg and British Alpine.
“Choose the breed you want to farm based on what you want to achieve with your business,” he advises.
When buying dairy goats, Hugo says it is important to look particularly at temperament and the udder.
“Examine the udder of the ewe thoroughly to ensure there are no lumps. If you can, milk the ewe with your hand. A goat that’s difficult to milk by hand will also be difficult to milk in the dairy parlour.”
In addition, look for goats with a shiny coat. “Goats with coarse, dry, curly hair may very well have some underlying health problem.”
Housing and enclosures
Before buying goats, ensure that you have adequate housing and fencing, says Hugo.
“Goats, whether raised for meat or milk, need basic protection from the elements: wind, rain and heat. You don’t need an elaborate barn; a simple, three-sided shed facing away from the prevailing wind will suffice.”
Hugo adds that goats are notorious escape artists, and their enclosures should therefore be constructed from, or surrounded by, strong fencing that they cannot climb. However, he advises against using barbed wire as it can injure the goats, especially their udders.
“For me, the ideal combination is a tension wire with an electric wire,” he says.
Picky eaters
According to Hugo, the general belief that goats will eat anything is not true.
“In fact, they’re picky eaters,” he says. They are browsers, not grazers like sheep, and what works for sheep will not necessarily apply to goats.
Good feeding practices will determine 90% of the quality of the milk, he says.
Hugo’s advice to prospective dairy goat farmers who want to put goats on pasture is to first take note of what’s available in the area as well as the average rainfall.
“Here, where we stay, it looks almost like a desert, so we feed our goats daily.”
The Bettiesville goats feed almost exclusively on hay, but depending on their stage of development they also receive concentrate.
“It’s important to give ewes extra feed during the last few weeks of pregnancy to improve their condition and milk production,” adds Hugo.
Always provide goats with sufficient fresh water, as they tend to ‘rinse’ their mouths after eating, he advises.
“The water in the troughs can very quickly become dirty and the goats won’t want to drink it. It also affects their appetite.”
Water troughs should be cleaned at least once a day, but preferably twice, especially during the summer months.
Hugo also recommends raising feeding troughs from the ground, as goats tend to climb on the troughs and trample on their food. They then refuse to eat it.
Medication
Goats should receive their vaccinations and other medication during the dry ewe stage. This is also an ideal time to groom their hooves; hoof trimming is important for the mobility and comfort of the ewe.
Hugo advises farmers to consult a vet about setting up a parasite control plan, especially during the dry ewe period, to prevent excessive levels of parasite exposure for newborns and the ewe. “It’s also important to check regularly for, and treat, any external parasites.”
Breeding
Dairy goats are seasonal breeders, conceiving exclusively in autumn. Hugo recommends a ratio of one mature ram to 35 ewes. Young ewes start breeding when they are about 14 months old and weigh a minimum of 36kg.
“When you’re planning your breeding, keep in mind the gestation period is about 150 days,” he says, adding that when the ewes come on heat, the possible kidding date should be noted.
“It’s important to have a kidding plan in order to prepare for the arrival of a large number of kids.”
Hugo’s flock usually achieves a kidding rate of 200%.
Kids are marked for identification immediately after birth. “You can’t do worthwhile recording unless all animals can be properly identified,” he stresses.
He records the sire, dam and kidding date of each kid immediately after birth by writing these details on masking tape with a permanent marker and tying it around the animal’s neck. This identification number will be tattooed inside its ear after two months.
When a ewe has kidded, Hugo places the kids in a portable pen measuring 1,4m by 1,4m, made from old pallets.
“Ewes with a strong maternal instinct are prone to steal kids from other ewes, so to ensure that each of the newborns receives enough colostrum, the kids must be kept separated with their mothers from the rest of the herd for the first five days after birth. After five days, the kids are taken from the ewes and fed by bottle.”
Bettie Bok
Hugo converted an old farmstead into an automatic, eight-point milking parlour and in September 2016 he and and his wife Lillibet made their first cheese.
He says that for good-quality production, dairy goats should be milked twice a day, 12 hours apart, seven days a week. A healthy Saanen ewe should produce between 2,5ℓ and 3ℓ of milk a day.
They produce chèvre (soft goats’ cheese), feta and haloumi.
“Our main clients are health shops. Goats’ milk is enriched with many necessary nutrients and is easily digestible,” he says.
Hugo adds that some consumers believe goats’ milk and goats’ milk products have an unpleasant odour and taste. To control this, he keeps the rams away from the ewes, especially after the females have kidded and are ready for milking.
Secure a market
It is a challenge to find a market for the products.
“These are niche products. Secure a market before investing in facilities or animals. Otherwise, you’ll lose money instead of earning a profit,” advises Hugo
