应用CNCPS法和体外产气法评价苹果渣作为反刍动物非粮饲料的潜力
Evaluation the Potential of Apple Pomace as Ruminant Non-grain Feed by Cornell Net Carbohydrate and Protein System and Gas Production Technique
摘要
Abstract
The experiment was performed to evaluate the nutritive value of apple pomaces by Cornell net carbohydrate and protein system (CNCPS) and in vitro gas production technique.In these series of researchs,apples pomace collected from Jinzhou (Liaoning province),Tangshan (Hebei province), Dangshan (Anhui province) and Beijing were used as test materials.The nutritive value of apple pomaces was evaluated by CNCPS,the fermentation situation were studied and their energy value was calculated.The results showed that there were significant differences in nutritive components between apple pomaces from different regions.As for the nitrogenous compounds,PA contents of 4 kinds of apple pomaces were all more than 60%,but PB1 contents were all less than 3%.For the carbohydrate compounds,CC contents were high (51% to 62%).The gas production (B) of Beijing apple pomace was the highest which was extremely significantly higher than others (P<0.01).And the gas generation rate (C) of Tangshan apple pomace was extremely significantly higher than Dangshan and Beijing apple pomaces (P<0.01).Dangshan apple pomace had the highest NH3-N content,extremely significantly higher than the others (P<0.01), there were significant difference in VFA among 4 kinds of apple pomaces (P<0.01).TDN and other energy values had obviously difference between apple pomaces from different places which Dangshan apple pomace had the highest energy value,extremely significantly higher than others (P<0.01).In conclusion,the apple pomaces from different regions had significant differences in chemical components and in vitro fermentation parameters.These series of experiments not only supplied the database of beef cattle common feeds but also establishsd the data foundation for the development and utilization of no-grain feeds,carried the point of scientific and reasonable utilization.关键词
