1不同物理形态开食料对犊牛生长发育、瘤胃发酵及血液指标的影响显示文摘本试验在湿热条件下,探究饲喂不同物理形态的开食料对犊牛生长发育、瘤胃发酵及血液指标的影响。试验采用36头荷斯坦母犊牛,随机分为3组(每组12头),分别自由采食颗粒状开食料(PSA)、粉末状开食料(PSB)和多颗粒状开食料(TS)。试验期63 d,其中1~42日龄为正常饲喂牛奶时期(断奶前期);43~49日龄为断奶期;50~63日龄为断奶后期。开食料从犊牛5日龄开始自由采食。在1、42、49以及63日龄晨饲前进行采血和称重,49和63日龄晨饲前胃管法采集瘤胃液。试验期间每天记录采食量和温湿度指数。结果表明,在湿热环境下:1)断奶期和断奶后2周TS组开食料干物质采食量、平均日增重和重料比高于PSA和PSB组,PSB组最低,但差异不显著(P>0.05)。2)TS组犊牛初次反刍时间较PSA组提前3.8日龄,较PSB组提前4.7日龄,差异均显著(P<0.05)。63日龄时,TS组瘤胃液氨氮含量显著低于PSA组(P<0.05)。3)42日龄时PSA组犊牛血液免疫球蛋白G含量显著高于TS组(P<0.05)。4)TS组犊牛初始腹泻时间较PSA和PSB组分别晚0.44和1.75日龄,但无统计学差异(P>0.05),TS组腹泻率最低。综合得出,湿热环境下,多颗粒状开食料较颗粒状开食料和粉末状开食料更能促进犊牛的生长发育,使犊牛尽早产生反刍行为。杜超 甄玉国 KERTZ Alois Francis 沈旖帆 卜登攀 2017动物营养学报2017,29,6:6
