【摘要】：为了对比水牛奶与代乳粉对水牛犊牛蛋白质代谢、肝功能及免疫功能相关血液指标的影响,试验选取初生犊牛16头,根据犊牛出生顺序依次分配到对照组(8头)和试验组(8头),对照组饲喂水牛奶,试验组饲喂能量水平实测值为20.35 MJ/kg的代乳粉。饲养试验从水牛犊牛7日龄之后计起,持续90 d,饲养试验期间水牛犊牛自由采食精料及饲草,饲养试验结束时晨饲前颈静脉采血。结果表明:在试验期间,对照组与试验组相比谷草转氨酶差异极显著(P0.01),谷酰转肽酶差异显著(P0.05),其他蛋白质及肝功能相关血液指标差异均不显著(P0.05),试验组犊牛的总蛋白含量低于对照组。对照组与试验组相比,总胆固醇含量差异极显著(P0.01),低密度胆固醇含量差异显著(P0.05),三酰甘油、高密度胆固醇含量差异均不显著(P0.05)。对照组与试验组相比,钠、氯含量差异均极显著(P0.01),钾、钙含量差异均不显著(P0.05)。试验犊牛的免疫球蛋白G、免疫球蛋白A、免疫球蛋白M、纤维蛋白原差异均不显著(P0.05)。说明饲喂水牛奶及代乳粉对水牛犊牛肝功能、蛋白质代谢相关的血液指标有一定程度影响,但对免疫相关指标则无影响。
[Abstract]:In order to compare the effects of buffalo milk and milk substitute powder on protein metabolism, liver function and immune function of buffalo calves, 16 newborn calves were selected. The calves were divided into the control group (8) and the experimental group (8) according to their birth order. The control group was fed with water milk and the experimental group was fed with milk substitute powder with the measured energy level of 20.35 MJ/kg. The feeding experiment began after 7 days of age and lasted for 90 days. During the feeding experiment, the buffalo calves were free to take concentrate and forage, and at the end of the feeding experiment, the blood was collected from the anterior jugular vein at the end of the feeding experiment. The results showed that there were significant differences in glutamic-oxaloacetic transaminase and glutamyl transpeptidase between the control group and the experimental group during the experiment period (P0.05). There was no significant difference in other protein and liver function-related blood indexes (P0.05). The total protein content of calves in the experimental group was lower than that in the control group. Compared with the experimental group, the total cholesterol content in the control group was significantly different (P0.01), the low density cholesterol content was significantly different (P0.05), and there was no significant difference in the triacylglycerol and high density cholesterol content between the control group and the experimental group (P0.05). Compared with the experimental group, the contents of sodium and chlorine in the control group were significantly different (P0.01), but there was no significant difference in the contents of potassium and calcium (P0.05). There was no significant difference in immunoglobulin G, immunoglobulin A, immunoglobulin M and fibrinogen between the tested calves (P0.05). The results showed that feeding water milk and milk substitute powder had a certain effect on liver function and protein metabolism of buffalo calves, but had no effect on immune related indexes.
