Calf diarrhoea results in additional expenses and unnecessary losses in the form of mortalities, the cost of medication, labor, substandard growth and a decrease in milk production during a heifer’s first lactation.
“Anyone with calf-rearing experience will agree with this,” says Dr. Louis Hoek, a veterinarian at CapeCross Veterinary Services in Tsitsikamma. Dr. Hoek notes that calf diarrhoea is also one of the most frustrating conditions to treat, especially since it takes up a considerable amount of time and requires a great deal of patience and dedication.
“It is generally believed that the colour of the diarrhoea will lead you to the cause of calf diarrhoea. In my opinion, however, a diagnosis cannot be based solely on this aspect. The colour and composition of the manure is a function of the rate at which it travels through the intestinal tract; it is not a direct consequence of the organism. Although a producer may at times guess the cause, I recommend dealing with the problem properly once a specific diagnosis has been made,” he says.
Main causes
According to Dr. Hoek, calf diarrhoea can be attributed to several significant causes.
In calves younger than three weeks:
• Rotavirus: It is the most common cause of diarrhoea. The manure can at times contain blood. If calves are treated properly, there ought to be no mortalities.
• Cryptosporidium: This is currently a huge problem in South Africa and generally presents itself along with a virus. It can spread very quickly, but calves that are treated properly can survive.
• Coronavirus: It is similar to the rotavirus but is not as common.

Shongololo Boer Goat Stud: Only The Best Will Do
South African Boer goats have proven popular worldwide for their ability to improve indigenous goat breeds. In addition, Covid-19 restrictions necessitated the establishment of electronic auctions, making it easier for foreigners to acquire outstanding genetic material exported by agents via established channels.
Feed Additives: A Veterinary Perspective
In an already volatile environment, dairy profit margins vary as milk prices and feed costs shift annually. Feed costs represent the largest input cost (an estimated 35 to 70% of the variable cost) in the production of milk. As a group of feed ingredients, feed additives can cause a desired physiological response in a non-nutrient way, such as pH shift, growth or metabolic modifier, and will usually be cost-beneficial.
Guard Against Lumpy Skin Disease
Most parts of the country received good rains during the rain season and producers are generally very optimistic. Wet seasons unfortunately come with their own set of challenges and veterinarians have cautioned livestock producers to keep an eye out for elevated biting insect loads, which may lead to conditions such as lumpy skin disease (LSD).
Climate-Related Hazards: How Smallholders Can Mitigate Its Consequences
Rainfed crop production remains the main source of food security and livelihoods for rural communities in South Africa but presents the challenge of climate variability due to its high dependence on weather variables such as rainfall and temperature.
Tips for a successful AI programme
The success of an artificial insemination (AI) programme depends on several factors that are largely within the control of the producer. It is interesting that those producers who take a hands-on approach to their cattle and inspect them regularly are also the ones who achieve the greatest success. Before his passing, Stockfarm spoke to Koot Louw, a well-known reproduction technologist from Brandfort in the Free State, about his insights into and advice regarding the AI process.

Land Reform: Case Studies In Kwazulu-Natal
Land reform in South Africa is complex. Land reform solutions are equally complex and within partnership and development models, this is no different – but there is hope. KwaZulu-Natal has several types of partnership models and the wide variation in farming systems, as well as their different needs, set each model up for different strengths and weaknesses.
Brahman Breeders In Limpopo Have A Winning Plan
Several breeders from the Bosveld Brahman Club in Limpopo are applying genetic excellence and genotypic correctness to stimulate the demand for their bulls. At several of the last auctions, the minimum standard of bulls was raised to achieve this goal.
A Brahman Dream Comes True
For as long as he can remember, JP Mlangeni wanted to be a farmer. It might have taken a few years, from being a teacher and later a businessman, but his dream finally took shape and today he runs a fully-fledged breeding and commercial Brahman farming enterprise in Mpumalanga.
