Abstract

The present study was done to investigate the effect of graded levels of dietary crude protein on enteric methane (CH 4 ) production from Murrah buffalo calves. Fifteen Murrah buffalo male calves were divided into 5 groups (Av. BW=153.05) and were fed total mixed rations containing wheat straw, maize fodder and concentrate mixture in different proportions so that the dietary crude protein level was 5, 7.5, 10, 12.5 and 15% in groups T 1 ,T 2 ,T 3 ,T 4 and T 5, respectively. The trial lasted for 30 days. Dry matter intake increased from 2.49 to 4.40 kg/d. Dry matter digestibility increased (P<0.05) from 48.64 to 61.97%. CH 4 emissions decreased (P<0.05) from 34.48 to 12.73 g/kg DMI with increasing protein level in the ration. Hence, CH 4 emissions were lower (12.73-12.83 g/Kg DMI) in animals fed rations containing 12.5 to 15% CP.
饲粮粗蛋白质分级水平对生长期默拉水牛犊牛养分利用和肠道甲烷排放的影响
本研究旨在研究日粮粗蛋白分级水平对Murrah水牛幼崽肠道甲烷(CH4)产生的影响。将15头Murrah水牛公牛犊分为5组(平均体重=153.05),饲喂不同比例的小麦秸秆、玉米饲料和浓缩物混合物的混合日粮,使T1、T2、T3、T4和T5组的日粮粗蛋白水平分别为5%、7.5%、10%、12.5%和15%。审判持续了30天。干物质摄入量从2.49千克/天增加到4.40千克/天。干物质消化率从48.64%提高到61.97%(P<0.05),CH4排放量从34.48下降到12.73g/kg DMI(P<0.01)。因此,喂食含12.5%至15%CP的口粮的动物的CH4排放量较低(12.73-12.83 g/Kg DMI)。
