Distillers grains (DG) are an excellent ruminant feedstuff. They are an excellent source both of energy and protein. In the production of alcohol, the starch, which is about two-thirds the composition of corn grain, is fermented to alcohol and CO2. The remaining nutrients are then concentrated by a factor of three. Corn protein of 10% is concentrated to 30% and fat (oil) from 4 to 12%. Fiber is...

In arid countries with long dry seasons and frequent occurrence of droughts, poultry litter is used often as a feedstuff for ruminants (Silanikove & Tiomkin, 1992; Deshck et al., 1998). It sometimes constitutes the main source of nutrients for the animals (Silanikove & Tiomkin, 1992). Similar situations exist in Southern Africa in particular during protracted droughts or when devastating veld f...

A case is made for the application of true ileal amino acid digestibility and true ileal reactive lysine digestibility (lysine availability) in poultry nutrition. Technical aspects of the true ileal digestibility assays are reviewed, as are factors influencing amino acid digestibility in the broiler. There is considerable variation in amino acid digestibility and lysine availability both within...

The purpose of the studies was to determine the proliferation activity of T and B lymphocytes as well as the metabolic and potential killing activity of blood phagocytes in pigs after the immunomodulation with the Bioimmuno preparation and/or immunisation with the ‘Respisure One’ vaccine against mycoplasmal pneumonia of swine. The studies were performed on piglets at the age of 4 weeks, divided...
