摘要

接收:修订:接受:在线发布:2018年10月21日2019年8月04日2019年8月06日2019年9月05日在巴基斯坦，重组牛生长激素(rbST)通常用于提高奶牛的产奶量。这就是为什么要进行这项研究，以检查它对水牛健康和生产的影响。选取水牛按体况评分(BCS)分为(低)BCS 1-3、(中)BCS 4-6、(高)BCS 7-9组(n=10)，对照组10头。各组从产后第70天开始至哺乳期结束，每隔1天给予rbST (boostin250) 35 mg，催产素1 ml (10 iu)。从每只动物身上采集血样并分离血清。牛奶样品用于牛奶成分参数。繁殖性能参数数据来源于养殖场记录。结果表明:夏季平均血清谷丙转氨酶(ALT)、谷草转氨酶(AST)和总氧化状态(TOS)值较高(P≤0.01)，总抗氧化状态呈相反趋势;中、高BCS水牛血清AST和TOS平均值显著(P≤0.01)升高。在夏季，高BCS组的怀孕水牛百分比很高。高BCS水牛的平均乳脂含量较高(P≤0.01)，中等BCS水牛的平均乳蛋白和乳糖含量极显著(P≤0.01)高于高BCS水牛。脂肪、蛋白质、乳糖和固体不脂肪(SNF)含量春季高于夏季。高产奶量组平均乳糖和SNF含量高于低、中产奶量组(P≤0.01)。综上所述，夏季和rbST处理能提高奶牛的产奶量，而春季催产素处理能降低产奶量，rbST和催产素处理对Nili-Ravi水牛的总体健康状况有不利影响。©2019 PVJ。版权所有

Effect of Recombinant Bovine Somatotropin (rbST) and Oxytocin on Health Biomarkers, Reproductive Performance and Milk Composition of Nili-Ravi Buffaloes (Bubalus bubalis)
