两种饲用苎麻及其青贮料的营养价值评价
Evaluation of nutritional value of two kinds of forage ramie and its silage
摘要
Abstract
Conventional nutrient analysis,Cornell net carbohydrate protein system(CNCPS)analysis and NRC model prediction methods were used to evaluate the nutritional value of two kinds of forage ramie and its silage.The test materials were Qingsizhu No.1 and Chuansizhu No.3,and the fresh grass test and silage test were carried out respectively,and three replicates were set in each group.The results showed that the concentrations of crude ash(Ash),calcium(Ca),phosphorus(P),neutral washing insoluble protein(NDICP),and neutral detergent fiber(NDF)of fresh grass in Qingsizhu No.1 were significantly higher than those of Chuansizhu No.3(P＜0.05),but there was no significant difference in relative feeding value(RFV)(P＞0.05).The carbohydrate(CHO)content of fresh grass in Chuansizhu No.3 was significantly higher than that in Qingsizhu No.1(P＞0.05).The true digestible non-fibrous carbohydrate(tdNFC),total digestible nutrients(TDNm),production level digestive energy(DEp),roduction level metabolic energy(MEp),production level lactation net energy(NElp),maintenance net energy(NEm)and gain weight net energy(NEp)of fresh grass in Qingsizhu No.1 were significantly higher than those of Chuansizhu No.3(P＜0.05).There was no significant difference in RFV,digestible nutrient content and emergy utilization between Qingsizhu No.1 silage and Chuansizhu No.3 silage(P＞0.05).The results show that the nutrient content,digestible nutrient content,and emergy ratio utilization of Qingsizhu No.1 are better than those of Chuansizhu No.3,but the RFV of Chuansizhu No.3 is comparable to that of Qingsizhu No.1,and the digestible nutrient content,emergy utilization,and RFV of Chuansizhu No.3 silage are comparable to those of Qingsizhu No.1.关键词
