Effect of enzyme preparation on production performance of weaned piglets.

The experiment was carried out to research the effect of enzyme preparation on production performance of weaned piglets,in which 60 50-days weaned piglets of Landrace with same day old and similar weight were selected to study.0.05%,0.1%,0.15% of compound enzymes for suckling pig were added into the basal diets of the treatment groups respectively.The results show that the average daily gain in treatments 1,2 and 3 is 420.9g,441.3g and 441.6g respectively,with 5.5%,10.7% and 10.9% rise more than the control group.The feed gain ratio is respectively 2.3,2.2 and 2.2,with 8%,12% and 12% increase higher than the control group,very significant variance,and 24%,28% and 28% of decreased diarrhea rate.
