摘要
Abstract
[Objective] The research aimed to discuss the feasibility of producing lactic acid by fermenting complete feed with many kinds of bacteria. [Method] Using the method of mixed bacteria and anaerobic fermentation, complete feed without antibiotic was fermented with plastic film bags. Taking lactic acid yield as the research index, no-antibiotic diet of weaned piglets was taken as materials to study the effects of fermentation time, temperature, feed-water ratio and pH on the lactic acid yield of complete feed. [Result] The best mixed bacteria combination was lactobacillus: microzyme: Bacillus subtilis = 3% : 2% : 1% . The optimum technology conditions of fermenting complete feed with the best bacteria combination were as follows:fermentation time of 3 d, the fermentation temperature of 35 °C , feed-water ratio of 1:0.8, pH of 6.5. [Conclusion] The research provided references for the production practices of weaned piglets.关键词
