Efficiency l Increase the utilization efficiency of feedstuff. Enhances the Livestock’s body to prevent disease the disease-resistant ability. It plays a good healthy role in preventing Huang pullorum disease (Yellow-white Dysentery). l Help the live stock growth by facilitating its digestion and strengthen their body. Improve the performance trait of weanling pigs. l Help the saws to avoid constipation l Increase egg laying. properties of product Good Palatability, lower cost, good economic returns. Can be a substitute for protein material in feedstuffs, such as fish meal, dregs of beans, powdered meat, blood meal. Application Ruminants Increase the density of rumen bacterial, adjust the fermentation of the stomach and intestines and stimulate its growth. Add this product in milk cow’s daily ration, Milkability increase 7.8% , butter-fat content increase 0.29%. Add 2.5% Saccharomyces cerevisiae in the daily ration of the milk goat early lactation period, Milkability increase 22%, feedstuff utilization efficiency increase 28.2%, butter-fat content increase 0.62%. Saccharomyces cerevisiae can boost the calf start to search for food earlier and increase its weight 6%—19%. Improve crude fiber Digestibility of the adult cattle. Add Saccharomyces cerevisiae in beef cattle’s daily ratio can increase its daily weight 3%—22.2%. Single stomach animals Saccharomyces cerevisiae may substitute 50%—100% fish meal in daily ratio of growing pig so as to lower the economic cost of the feedstuff and upgrade the utilization efficiency 2.1%—2.93%. Add Saccharomyces cerevisiae 5% in sows basis daily ration, The weight of its first baby sow increase 14.6%, Milkability increase 8.3%, survival rate increase 8.3%. There is no significant effect to poulards and egg-laying hens while using Saccharomyces cerevisiae to substitute partial fish meal in their basic daily ratio. aquaculture It is ideal protein source to substitute fish meal. It raise adult carp Production 31.4 %—83.0% , upgrade living rate 1%—11 %,heighten weight 3%—3.7%,improve utilization of feedstuff 1.6%—10.0%. Substitute 40% daily fish meal of the shrimp. the length of the prawn increase 0.26—0.35cm , upgrade living rate 1.5%—2.4% , improve utilization of feedstuff 5.36 %—7.58%,heighten weight 9.4 %—11.5%.
