Serum selenium and liposoluble vitamins in Japanese Black cows that hadstillborn calves

[摘要] References(21)Stillbirth and dystocia are major factors that negatively affect beef production. Wesought to clarify serum selenium and liposoluble vitamin levels in Japanese Black cowsthat gave birth to stillborn calves (stillbirth cows). Blood samples were collected from103 stillbirth cows and 95 cows that gave birth to healthy calves (control cows). Serumlevels of selenium (45.8 ± 16.0 ng/ml) and vitamin A(73.0 ± 24.8 IU/dl) in stillbirth cows were lower(P<0.05) than those in control cows (52.2 ± 8.9ng/ml and 93.3 ± 14.8 IU/dl,respectively). Our findings suggest that appropriate serum selenium and vitamin A levelsare important for calving cows.
