摘　　要：本研究旨在通过数据模型估算生长期萨能奶山羊的能量和蛋白质需要量。为确定模型参数,采用数据库检索的方法收集文献,按照文献排除标准,共纳入文献9篇、419只萨能奶山羊的数据进行Meta分析。提取的文献定量指标包括体重(BW)、空腹体重(EBW)、平均日增重(ADG)、产热量(HP)、代谢能摄入量(MEI)、沉积能量(RE)、代谢蛋白质摄入量(MPI)和体蛋白质含量(BPC)。通过拟合获得主要模型:维持净能(NEm)Log HP(MJ/kg EBW0.75)=-0.534 08(±0.025 01)+0.424 45(±0.020 40)×MEI(MJ/kg EBW0.75);生长净能(NEg):NEg(MJ/kg EBW0.75)=1.29 471×100.644 54×EBW0.294 71;维持净蛋白质(NPm):RN(g/kg EBW0.75)=-0.456 21(±0.514 35)+3.035 90(±0.638 35)×NI(g/kg EBW0.75);生长净蛋白质(NPg):NPg(g/d)=0.94 717×102.318 84×EBW-0.058 3。通过模型计算得出10~40 kg萨能奶山羊的NEm为0.29 MJ/kg EBW0.75,维持代谢能(MEm)为0.483 0 MJ/kg EBW0.75;NPm为2.85 g/kg EBW0.75,维持代谢蛋白质(MPm)为3.314 7 g/kg EBW0.75。体重10~40 kg阶段,日增重为100~250 g/d时的NEg需要量为0.77~3.41 MJ/d,生长代谢能(MEg)为3.848~17.743 MJ/d;NPg为12.00~34.33 g/d;生长代谢蛋白质(MPg)为17.14~49.04 g/d。因此,本文得出生长期萨能奶山羊的能量及蛋白质需要量与NRC推荐值存在较小差异,可以使用本研究得出的需要量公式及参数作为参考。The aim of this study was to estimate the energy and protein requirements for maintenance and growth of Saanen dairy goats from 10 to 40 kg by means of data models.To determine the model parameters,the literature was collected by means of database retrieval.According to the exclusion criteria of literature,nine literatures including the data of 419 Saanen dairy goats were included for Meta-analysis.The following quantitative data extracted from the literature were included:body weight(BW),empty body weight(EBW),average daily gain(ADG),empty body gain(EBG),heat production(HP),Metabolizable energy intake(MEI),retained energy(RE),Metabolic protein(Metabolizable protein intake,MPI)and body protein content(BPC).The regression equations established were as follows:for Net Energy for maintenance(NEm):LogHP(MJ/kg EBW0.75)=-0.53408(±0.02501)+0.42445(±0.02040)×MEI(MJ/kg EBW0.75);for Net Energy for gain(NEg):NEg(MJ/kg EBW0.75)=1.2940.64471×1054×EBW0.29471(kg);for Metabolizable Protein for maintenance(NPm):RN(g/kg EBW0.75=-0.45621)(±0.51435)+3.03590(±0.63835)×NI(g/kg EBW0.75);for Net 2.318 Protein for gain(NPg):NPg(g/d)=0.94717×108×EBW-0.0583(kg).The NEm requirement was 0.29 MJ/kg EBW0.75,and the Metabolizable energy for maintenance requirement was 0.4830 MJ/kg EBW0.75.The NPm requirement was 2.85 g/kg EBW0.75,and the Metabolizable protein for maintenance requirement was 3.3147 g/kg EBW0.75.The NEg requirement ranged from 0.74 to 3.41 MJ/d,the Metabolizable energy for gain requirement ranged from 4.94 to 19.17 MJ/d,the NPg requirement ranged from 12.00 to 34.33 g/d,and the Metabolizable protein for gain requirement ranged from 17.14 to 49.04 g/d for goats with BW ranging from 10 to 40 kg and ADG ranging from 100 to 250 g/d respectively.In conclusion,The results obtained by Meta-analysis in this paper support the hypothesis that energy and protein requirements of Saanen dairy goats are within a reasonable range and different from those of local breeds,and recommended parameters such as NRC.Therefore,the energy and p
