Blood biochemical levels of reproductive disorders cases in Limousine Crossbred cows

This study determined the differences in the biochemical blood levels of Limousine crossbred cows with reproductive disorders and cows that successfully become pregnant. Limousine crossbred cows (45) were artificially inseminated, and observed for reproductive disorders after 42 days. The observation was conducted by using rectal palpation and Ultrasonography. The cows were grouped into pregnant cows and cow with reproductive disorder (infertile). The cholesterol level, calcium, total protein, and blood glucose were analyzed and statistically tested by t-test using Microsoft Excel 2019 program. The observation of cows was divided into two groups, eight of 45 were normal or pregnant and 37 of them had reproductive disorder: 8 of repeat breeding, 10 of ovarian dysfunction, 11 of cystic ovary, and 8 of silent heat. The total cholesterol of Limousine crossbred cow varied, pregnant cows demonstrated higher cholesterol than those with the reproductive disorder. The blood protein, calcium, and glucose concentration also showed significantly low concentrations in Limousine cow with reproductive disorders. In conclusion, cows with reproductive disorders were marked by low cholesterol, calcium, total protein, and glucose levels.
