摘要

为了测定血浆和牛奶中的生化指标变异性，以及关于每日乳糖含量类别（指示乳腺炎风险）和体细胞计数类别（指示动物健康状况）的血液学指标，对75头荷斯坦奶牛的血液和牛奶进行了采样。奶牛是在一个商业奶牛场饲养的。统计分析表明，哺乳期、产次和具有统计学意义的每月测量值（P<0.01）都会影响生化和血液学参数。由于乳腺炎评分类别（根据每日乳糖含量、DLC和体细胞计数、SCC），分析的生化和血液学参数之间存在差异，在某些性状中具有统计学意义（P<0.05）。此外，在某些性状中，乳腺炎评分（SCC的DCL）的趋势也有所不同。因此，当使用测试日记录作为动物乳腺炎风险和健康状况指标时，应使用两种评分方法。最后，在乳腺炎风险或乳腺炎发生的情况下，为了明确检测，应使用其他诊断方法（如各种乳腺炎测试）。

The Variability of Biochemical and Hematological Parameters Depending on the Mastitis Occurence in Dairy Cows

With the aim of determination of biochemical indicators variability in the plasma and milk and hematological indicators regarding the daily lactose content classes (indicating the mastitis risk) and somatic cell counts classes (indicating the animal’s health status), blood and milk of 75 Holstein cows were sampled. The cows were reared on a commercial dairy farm. A statistical analysis demonstrated that the lactation stage, parity, and statistically significant monthly measurement P < 0.01) affected both the biochemical and hematological parameters. The differences between the analyzed biochemical and hematological parameters due to the mastitis score classes (according to the daily lactose content, DLC, and the somatic cell count, SCC) were present and statistically significant (P < 0.05) in some traits. Furthermore, different trends regarding the mastitis scoring (DCL of SCC) were determined in some traits. Therefore, when using the test-day records as an animal’s mastitis risk and health status indicator, both scoring ways should be used. Finally, in the case of a mastitis risk or mastitis occurrence, other diagnostic methods (such as various mastitis tests) should be used for the sake of an unambiguous detection.

期刊介绍： POLJOPRIVREDA“ (AGRICULTURE), a scientific-professional journal has been issued since 1995 by the Faculty of Agriculture in Osijek and Agricultural Institute Osijek . The journal is a successor of the former one „Science and practice in agriculture and food technology“ printed from 1982 to 1994. The journal „Poljoprivreda“ is known for publishing scientific and professional articles from all fields of agricultural science and profession. The papers are reviewed. Articles are categorized by two independent referees and approved by Editorial board and Editor – in – chief. Summaries of master"s and doctor"s theses are also published as well as other contributions by the special decisions of the Editorial board.
