Problems solved by technology

However, in the process of repeated experiments, the effect was not satisfactory, the types of microorganisms in the ileum did not increase significantly, and the nutritional diarrhea of ​​broilers did not significantly improve. One of the possible reasons for the analysis is that the source of lipase fed to broilers is single and cannot be completely decomposed. Utilization of different types of fats results in failure to meet fatty acid requirements of broilers

Abstract

The invention relates to a feed additive containing lipase from different sources, and application thereof in a yellow feather broiler feed. The feed additive is prepared from the following components in percentage by weight: 40 percent to 60 percent of chicken pancreatic lipase, and 40 percent to 60 percent of aspergillus niger lipase. Therefore, The feed additive provided by the invention has the advantages that the diversity of microorganism species in yellow feather broiler ileum can be remarkably improved, and the digestibility of yellow feather broilers on grease is improved, so that trophic diarherra of the broilers is reduced.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a feed additive containing lipase from different sources and the application of the feed additive in yellow feather broiler feed. Background technique [0002] Grease feed has the characteristics of high metabolic energy value, and its energy value is 2.25 times that of carbohydrates and proteins. It is one of the indispensable important raw materials in the diet of professional chicken farmers for standardized production and feeding of broilers. Therefore, farmers will be in broiler chicken A certain proportion of fat is added to the feed to meet the growth needs of broilers. Adding fat to livestock and poultry diets has become one of the technical ways to improve high-energy nutrition. However, in recent years, the price of energy feed raw materials, especially oil, has been rising. How to improve the utilization rate of energy in feed, reduce the amount of oil added, reduce feed ...
