Abstract :This study was undertaken to investigate the relationship between blood levels of Ca, Zn, Mg, K, and Na and the occurrence of retained placenta and abortion in cows. Serum samples from 34 cows were analyzed insert ignore into journalissuearticles values(18 with retained placenta, 10 without retained placenta insert ignore into journalissuearticles values(control);, and 6 that had aborted);. Ca and Zn levels in cows with retained placenta were significantly lower than those in the control group. The serum Zn levels of aborted cows were higher insert ignore into journalissuearticles values(P < 0.001); than those of cows with retained placenta. Cows in the control group and those with retained placenta were divided into subgroups based on age insert ignore into journalissuearticles values(3, 4-6, 7-9 years old);, type of parturition insert ignore into journalissuearticles values(normal, dystocia);, and sex of calves insert ignore into journalissuearticles values(male, female);. The serum Ca concentration of 3-year-old cows with retained placenta was significantly higher insert ignore into journalissuearticles values(P < 0.05); than that of those 7-9 years old. It is concluded that lower serum Ca and Zn levels in cows may induce placenta retention.
