1)肉牛综合净能参考《肉牛饲养标准》[36](NY/T 815—2004)及《中国饲料成分及营养价值表(2021年第32版)》[35]进行计算:肉牛综合净能(MJ/kg DM)=消化能(DE)(MJ/kg DM)×Kmf;DE(MJ/kg DM)=0.209×粗蛋白质(CP,%)+0.322×粗脂肪(EE,%)+0.084×粗纤维(CF,%)+0.002×无氮浸出物(NFE,%)2+0.046×NFE(%)-0.627;Kmf=Km×Kf×1.5/(Kf+0.5×Km);Km=0.1875×[DE/总能(GE)]+0.457 9;Kf=0.523×(DE/GE)+0.005 89;GE(MJ/kg DM)=0.239 3×CP(%)+0.397 5×EE(%)+0.200 4×CF(%)+0.168 6×NFE(%)。The NEmf of beef cattle was calculated according to the Beef Cattle Feeding Standard[36] (NY/T 815—2004) and China Feed Composition and Nutrition Value Table (32nd ed,2021)[28]: NEmf of beef cattle (MJ/kg DM)=DE (MJ/kg DM)×Kmf; DE(MJ/kg DM)=0.209×CP(%)+0.322×EE(%)+0.084×CF(%)+0.002×NFE(%)2+0.046×NFE(%)-0.627; Kmf=Km×Kf×1.5/(Kf+0.5×Km); Km=0.187 5×(DE/GE)+0.457 9; Kf=0.523×(DE/GE)+0.005 89; GE (MJ/kg DM)=0.239 3×CP(%)+0.397 5×EE(%)+0.200 4×CF(%)+0.168 6×NFE(%). 2)肉羊代谢能参考《肉羊饲养标准》[37](NY/T 816—2004)进行计算:肉羊代谢能(MJ/kg DM)=DE(MJ/kg DM)×0.82。The ME of mutton sheep was calculated according to the Mutton Sheep Feeding Standard[37] (NY/T 816—2004): ME of mutton sheep (MJ/kg DM)=DE(MJ/kg DM)×0.82. 3)奶牛产奶净能参考《奶牛饲养标准》[38](NY/T 34—2004)进行计算:奶牛产奶净能(MJ/kg DM)=0.550 1×DE(MJ/kg DM)-0.395 8。The NEL of dairy cows was calculated according to the Dairy Cow Feeding Standard[38] (NY/T 34—2004): NEL of dairy cows (MJ/kg DM)=0.550 1×DE(MJ/kg DM)-0.395 8. 4)粗饲料分级指数(GI)参考《饲草营养品质评定 GI法》[25](GB/T 23387—2009)进行计算:绵羊GI=代谢能(ME)×干物质随意采食量(VDMI)×CP/中性洗涤纤维(NDF),其中VDMI=29.75×BW0.75/(NDF×1 000),体重(BW)规定以40 kg计算;奶牛GI=NEL×VDMI×CP/NDF,其中VDMI=1.2×BW/NDF,BW规定以600 kg计算。The roughage grading index (GI) was calculated by referring to the Evaluation of Forage Nutritional Quality-Grading Index (GI) Method[25] (GB/T 23387—2009): GI for sheep=metabolizable energy (ME)×voluntary dry material intake (VDMI)×CP/neutral detergent fiber (NDF), inside VDMI=29.75×BW0.75/(NDF×1 000), BW was specified at 40 kg; GI for dairy cows=NEL×VDMI×CP/NDF, inside VDMI=1.2×BW/NDF, BW was specified at 600 kg. 5)辣椒茎秆肉牛综合净能中所使用的CF含量及辣椒粉中NDF、酸性洗涤纤维(ADF)含量采用马绍楠等[39]的研究中的公式进行计算:CF(CFNVT)=-2.512+0.838×ADF;NDF(CFNVT)=7.682+1.250×ADF;ADF(CFNVT)=4.157+1.132×CF。The CF content used in the NEmf of chili stalk for beef cattle and the contents of NDF and acid detergent fiber (ADF) found in chili powder were calculated by the formula in the study of Ma, et al[39]: CF(CFNVT)=-2.512+0.838×ADF; NDF(CFNVT)=7.682+1.250×ADF; ADF(CFNVT)=4.157+1.132×CF. |
