Effect Of Combined Ensymes And Probiotics On The Performance Of Piglets

Three experiments are conducted to study the effect of enzymes and probiotics on the performance of piglets. The first experiment is devised and operated to study the biology character of Lactobacillus plantarum and Bacillus subtilis which are used to produce probiotics in suitable condition. The second experiment is the study about Aspergillus Niger which is used to produce combined enzymes. The third experiment is the application of the two products to piglets. The result is listed below:1. The ability for Lactobacillus plantarum and Bacillus subtilis to tolerate high temperature and strong acid is not high enough to survive in the condition of 75-80℃ and PH2-3. The suitable fermentation of the rate of C and N recourses is 7:3 for Lactobacillus plantarum, 8:2 for Bacillus subtilis.2. The suitable fermentation of the comparability between C and N recourses is 8:2 for Aspergillus Niger to produce phytase. Phytase can still keep active when it is in the condition of 55℃ and pH 3.3. Add enzymes and probiotics respectively to the diet of weaning...
