It all starts with the electronic ear tag, he says, and initially it does not matter which ear tag is used, whether high or low frequency. However, the high-frequency tag presents many advantages, the most of important of which is that the scanner can detect the frequency from the ear tag over a greater distance.
This means that animals do not have to be pushed through a crush one by one in order to obtain data from the tag. A group of animals can enter the crush together and the scanner will pick up each ear tag and forward the data to the computer software. “This not only reduces the hours worked, but also reduces stress in the animals. And this is just the beginning,” says Dr Hentzen.
Data that spans an entire lifetime
Dr Hentzen sketches the following scenario to illustrate his point: Every animal entering the feedlot is equipped with a high-frequency ear tag attached at birth. The animal’s data has been recorded since birth, which means that its entire breeding and medical history is known to the feedlot operator.
While in the feedlot, the animal’s history is kept up to date, including the type and amount of feed the animal receives, its average daily weight gain, and its medical treatments. The information captured is very accurate and the human factor is eliminated.
Better information means better decisions, which ultimately relates to feedlot profitability. With the correct treatment date captured, the scanning of marketable animals can identify those animals that have not yet gone through their withdrawal period.

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.
