中国8个不同来源DDGS蛋公鸡氨基酸代谢率及评价方法相关性研究
Study on Amino Acids Metabolizability and Its Correlation of Evaluation Methods for Adult Roosters of Eight DDGS from Different Resources in China
摘要
Abstract
[Objective] A method for rapiding evaluationthe of amino acid metabolizability in DDGS was found to provide scientific basis of rational utilization in DDGS on roosters. [ Method ] 45 Hyline brown adult roosters, average body weight (2.6±0.2) kg, were randomly allocatted into 9 groups with S replicates per treatment, A 2x9 Youden Square design was carried out for two periods metabolism experiment to determine amino acid metabolizability of 8 DDGS from different sources in China by N-free diet methods and researched the amino acid metabolizability correlation with the DDGS color and water solubles matter. [ Result] The range of the 8 DDGS total amino acids apparent metabolizability and true metabolizability is 60.18%-74.06% and 74.13%-89.15%, the lysine apparent metabolizability is lower than 60% and true metabolizability is from 63.08% to 82.07%. There is high positive correlation between water solubles matter and lysine true metabolizability (& = 0.7601). [Conclusion] The results indicate that there are variations of amino acids metabolizability between DDGS from different sources. Lysine true metabolizability of DDGS on poultry can be estimated by determining their water solubles matter.关键词
