Feed quality and salmonella

Salmonella is responsible for some of the most widespread food poisoning outbreaks in the world. Since salmonella is heat sensitive, the heat treatment of feed in the pellet press’s preconditioner has become standard practice to improve feed hygiene. The dilemma with this strategy is that pelleting offers no protection against recontamination of feed. [View article]

Energy values of maize in feed formulation

Maize is the biggest cereal component of both poultry and swine feed. In addition to large variation in the proximate nutrient content of maize, the question whether there is a true difference in the nutritive value of white vs yellow maize in South Africa has been frequently asked by industry nutritionists.

Nutritional principles applicable to game

With the development of intensive game breeding programmes, the nutritional needs of game changed completely. Proper nutritional practices and feeding methods are essential if game farmers want to be part of a profitable industry to satisfy the needs of rare and traditional game in Africa going forward.
