Izaak Breitenbach, general manager of the Broiler Organisation at the South African Poultry Association (Sapa), says there are three basic breeds used by the broiler industry worldwide, namely the Ross, Arbor Acres and Cobb. These three breeds were bred specifically to meet the requirements of broiler production.
These breeds are owned by two international companies that invest a lot of research into breeding the right type of genetics that will guarantee success. They select for rapid growth, a good feed conversion ratio, white feathers, low mortality and disease resistance. “These researchers are constantly striving to improve the breeds and are working on around 60 traits at a time,” he explains.
The right chicken
Several breeds have been tested in the poultry industry as a whole, but in the broiler industry, each breed has a specific function. When you start farming on a large scale, it is best not to use one breed for two purposes. Roosters that breed layer hens, for example, are not suitable for breeding broilers. These chickens have poor growth, feed too much and are not fleshy – on a plate they look rather emaciated and are anything but juicy.
Layer hens, explains Izaak, are suitable for egg production but not for broiler production. Backyard chickens, on the other hand, are slow growers and suitable for occasionally laying an egg. Their real purpose is to scratch in the garden to keep if free from pests.

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.
Pay Attention To Orf In Your Flocks
Some of our readers may have treated or heard of sheep or goats that have been infected with orf (vuilbek).
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.
