The Protein Digestibility of Enzymatic Hydrolysis Feather Meal via vitro and Its Applicatioan in Growing Pigs
摘要
Abstract
To determine the protein digestibility of enzymatic hydrolysis feather meal in vitro and explore the effects of dietary feather meal replacement of fish meal on growth performance and protein digestibility in growing pigs. The gastrointestinal environment was simulated in vitro, protein digestive test of hydrolysis feather meal and enzymatic hydrolysis feather meal were conducted for measurement of digestibility by pepsin-trypsin hydrolysis method. A total of 135 growing pigs were randomly divided into three groups with three replicates, the control group (3 % of the Peruvian fish meal group), the test group I and H (50 % and 100 % feather meal replacement of Peruvian fish meal by crude protein content). The results showed that protein digestibility of enzymatic hydrolysis increased by 15.38% (P<0.05) compared with hydrolysis feather meal in vitro. In the group of 50% and 100% feather meal replacement of Peruvian fish meal, the average daily gain and average daily feed intake were not different significantly to the control group (P>0.05); feed conversion ratio and protein digestibility were also not significant to the control group (P>0.05). Combination of production performance and economic analysis, the 100% feather meal raplacement was the best. There were practicality and feasibility to practice of fish meal replacement with enzymatic hydrolysis feather meal in the production.关键词
