不同胎次奶牛血液生理生化指标分析
|
摘要
为了更好的了解不同胎次奶牛血液生理生化指标的变化规律,进一步指导实际生产工作,本试验选用体况相近的不同胎次荷斯坦奶牛,对奶牛的血液样品进行血常规指标和血液生化指标检测。结果表明:血常规测定发现5胎奶牛白细胞数量明显增多,显著高于2～4胎奶牛(P<0.05);2～4胎奶牛红细胞数显著高于5胎和1胎奶牛的红细胞数(P<0.05);1胎奶牛的血红蛋白却显著高于2～5胎奶牛;5胎奶牛的中性粒细胞百分数显著升高(P<0.05)。血液生化测定发现1胎奶牛内ALKP的含量与钙离子浓度显著高于2～4胎(P<0.05),趋势都是随着胎次的增加含量逐渐降低。结论得出母牛胎次与血液生理生化指标具有一定的相关性,可为不同胎次母牛的饲养管理提供依据。
The objectives are to better understand the change rule of blood physiological and biochemical indexes of different-parity dairy cows, thus to guide the practical production. Holstein cows of different parities with similar body conditions are chosen in this experiment. The blood routine indexes and blood biochemical indexes of Holstein cows are examined. The results showed that the number of white blood cells increased significantly in the 5 thparity cows, obviously higher than that in the 2 nd-4 thparity cows(P<0.05). The number of erythrocytes in the 2 nd-4 thparity cows was significantly higher than that in the 5 thparity and primiparous cows(P<0.05). However, the amount of hemoglobin in primiparous cows was higher than that in the 2 nd-5 th parity cows(P<0.05). Furthermore, the percentage of neutrophils in the 5 thparity cows showed a significant rise(P<0.05). According to the blood biochemical results, ALKP content and calcium ion concentration in primiparous cows were significantly higher than those in the 2 nd-4 thparity cows(P<0.05), and the trends were all reduced gradually with the increase of parity. Thus, there are certain correlations between physiological and biochemical indexes and different parities. Our results will provide a basis for the breeding management of different-parity cows.
