Abstract

It is generally perceived that high quality energy and protein sources in diets for newly-weaned pigs, such as milk powders, lactose and cooked cereals, promote better performance after weaning. However, their higher cost and stability of supply sometimes requires nutritionists to explore potential for other ingredients for use in the formulation of weaner diets. Recent research in grower pigs demonstrated that lupins could be included at up to 350g/kg in place of soybean meal, without compromising growth, carcase composition or meat quality (Kim et al., 2007). However, the use of lupins in a weaner diet to reduce or replace more expensive protein sources, such as milk products, has not been examined to date. The hypothesis tested was that increasing the concentration of whole or dehulled Australian sweet lupins in place of milk by-products such as skim milk powder and dried whey in a diet would reduce performance of weaner pigs.
