基于尼龙袋法评价啤酒糟、罗汉果渣和菠萝皮在水牛瘤胃中的降解特性
Evaluating degradation characteristics of brewer's grains,Siraitia grosvenorii pulp,and pineapple peel in buffalo rumen using nylon bag method
摘要
Abstract
The experiment aimed to study the nutritional components of three unconventional feedstuffs(brewer's grains,Siraitia grosvenorii pulp,and pineapple peel)and their degradation characteristics in the buffalo's rumen.The experiment selected three healthy Murrah crossbred female buffaloes with permanent rumen fistulas and conducted in vivo tests using the nylon bag method.The results showed that the degradation rates of DM,CP,NDF,and ADF of the three unconventional feedstuffs gradually increased in the buffalo's rumen over time.The DM,NDF,and ADF ruminal degradation rates of pineapple peel were significantly higher than those of brewer's grains and Siraitia grosvenorii Pulp at various time points(P＜0.05).Except for 12 h and 72 h,the CP degradation rate of pineapple peel at various time points was significantly higher than that of brewer's grains and Siraitia grosvenorii pulp(P＜0.05),and the rapid degradation part of DM and CP of pineapple peel was significantly higher than brewer's grains and Siraitia grosvenorii pulp(P＜0.05).The effective degradation rates of DM,NDF and ADF of the three roughages were ranked as pineapple peel＞brewer's grains＞Siraitia grosvenorii pulp.The study suggests that pineapple peel and brewer's grains have higher nutritional value and can serve as high-quality roughage for buffaloes.关键词
