I receive many phone calls from communal farmers requesting help with sheep, goats or cattle that are ‘mysteriously dying’. My first question is: were the dead animals vaccinated beforehand?
The answer is often “Yes”. But when I ask a few more questions, I’m told that the livestock were ‘vaccinated’ with Ivermax, Ecomectin, or some other parasiticide.

WHAT IS A VACCINE?
In very simple terms, a vaccine contains parts of the disease itself (albeit rendered harmless), and this enables the body to develop an immune response.

Growing sweet potatoes
The sweet potato is a warm-season crop and does not fare well in cool temperatures. Implementing a crop rotation strategy is also essential to keep pests and diseases at bay.
The evolution of power in SA's agri machinery market
It is unlikely that South Africa’s commercial agriculture sector would have achieved its internationally respected status were it not for the investment that farmers have made in mechanisation. Lloyd Phillips spoke to a number of experts about some of the main agricultural machinery sales trends.
Putting crop rotation into perspective
When developing a crop rotation programme, one must take into consideration the various pests and diseases that may infect different crops in order to avoid disastrous results, says Bill Kerr.
The changing environment
The Internet of Things, where machinery and devices (often fitted with sensors) share data online, has enabled tractors and other agricultural machinery to become far more efficient and easier to operate. This, combined with mechanical innovations, is helping farmers produce more with less. Glenneis Kriel reports.
Giving farmers the advantage!
New machinery is indispensable as a support for agricultural activities during difficult times such as COVID-19, says Jaco du Preez, product specialist at CNH Industrial, distributor of New Holland in South Africa.
Breeding for efficiency adds value for this cattle farmer
Anneri Otto, who farms near Coligny in North West, never planned on becoming a farmer. However, when unfortunate circumstances forced her to take charge of her husband’s operation, she rose to the challenge, and now produces Hereford and Angus cattle, as well as pecan nuts. Pieter Dempsey reports.
Improving the stud one animal at a time
Dirco Swart, owner of Blinkmeneer Beefmasters in Frankfort, says that the future of the Beefmaster is bright, thanks to the breed’s adaptability and breeders’ passion for improvement.
Controlling biting flies
Biting flies are not only a nuisance, but can also transmit diseases and deliver painful bites, says Dr Mac.
A soya bean range for all conditions
Nico Barnard, an agronomist in the central Highveld for Pannar, explains the importance of planting different soya bean cultivars to spread risk. This is how Pannar’s soya bean range can help!
Why plants need nitrogen
This element, which is found in the chlorophyll of plants, is responsible for vegetative growth and is therefore crucial to the success of the crop.
How About A Covid Pill?

Drugmaker Backpedals on Specialty Status for COVID-19 Drug
Facing public criticism, the maker of a promising coronavirus drug said Wednesday it will waive a special regulatory designation that could have allowed it to block competition and boost profits for its treatment.
Can Blood from Coronavirus Survivors Treat the Newly ILL?
Hospitals are gearing up to test if a century-old treatment used to fight off flu and measles outbreaks in the days before vaccines, and tried more recently against SARS and Ebola, just might work for COVID-19, too: using blood donated from patients who’ve recovered.
Why do we need mice to develop a vaccine?
It’s a basic rule of medical research: Before you inject anything into humans, conduct experiments on animals—frequently mice—to determine whether treatments are safe and effective.
