The major constraint in smallholder animal production systems is the deterioration in the quality of livestock feed resources during the dry season. Protein and energy are the most limiting nutrients. Crop residues, which provide additional sources of forage to livestock early in the dry season, are also low in these nutrients. This results in poor animal productivity during this period. Soyabean, an increasingly popular crop among smallholder farmers in the developing countrries like Zimbabwe, is a high quality protein source that can be utilized to ease this problem. However raw soyabeans contain anti-nutritional factors and urease. The anti-nutritional factors tend to affect non-ruminants whilst urease has an effect on ruminants. This show the simple way of removing anti trypsin through dry heating and gives evidence of the usefullness of such a technology.
