摘要
The Heilongjiang Soybean Research Institute not only focuses on improving yield and quality of soybean, but also exploring the development of various high quality soybean byproducts. Currently, the institute uses advanced extraction technology, the institute also produces new soybean chips and vitamin E from soybean pulp, soybean peptides, phosphatides and oligosaccharides. 120 broilers were randomly divided into 4 groups with 6 replicates in each group and 5 chicken in each replicate. The authors studied influence on performance and body quality of broiler chicken by using soybean phosphatides to take the place of 0.5%, 1% and 1.5% corn of basal daily grain. Conclusion indicated that rates of broiler chicken weight gain were 2.1%, 4.4% and 8.7%, feed utilization rates raised 3.5%, 5.2% and 8.1%, costs reduced 2.3%, 3.5% and 5.8%, chest muscle rates improved 14.7%, 0.9% and -0.49%, belly fat rates improved 11.06%, 20.28% and 44.75% by using soybean phosphatides to take place of corn in daily grain after 42 days. More recently, the study is also involved in the research on improving the meat quality of chicken by adding extracted soybean peptide and phosphatides into feed. Furthermore, nearly 98% post-consumer waste oil with high acid value can be converted into biodiesel by using an effective supercritical methanol method.
