Feedlots that have the resources and know-how to prepare weaner calves on natural grazing, combined with complementary feed (backgrounding), can purchase lighter calves. Animals that are sent to the feedlot directly should be heavier (at least 220kg), as this supports sufficient feed for efficient growth from the outset.
Weaner calves make up a feedlot’s biggest expense at 60%, while the cost of feed and infrastructure each contribute approximately 20%. Given these figures, it is clear that judicious calf purchases are crucial for profitability.
Heavier is better
International research indicates that heavier calves (within limits) are more profitable than lighter calves entering the feedlot.
Tom Brink, former senior vice president and risk manager of Five Rivers Cattle Feeding – the largest feedlot in the world – was quoted in Beef magazine as saying that Five Rivers Cattle Feeding benefitted from the data of the more than 1,5 million head of cattle they marketed annually.
From this he was able to deduce that heavier calves ingest more feed and grow at a rate of 1,5kg/day, whereas lighter calves grow 1,33kg/day. When considering the costs, the break-even point for the heavier calves is approximately R50/kg lower than that of the lighter calves. Larger calves grow faster and more efficiently than lighter calves, he stated.
Lukas Eksteen from Bufland feedlot agrees, adding that because a calf can ingest roughly 3% of its live weight, lighter calves simply cannot consume enough feed to grow adequately.

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.

Sanele Mbele: Where Passion And Skill Meet
Passion for farming runs strong in the Mbele family’s veins. Sanele Mbele, from the farm Rietspruit in the De Jagersdrift area near Dundee, has inherited this passion in huge dollops.
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.
