牦犊牛缺硒病防治的研究

Prevention and treatmennt of selenium deficiency in yak calves

采用皮下注射氢氢化铝亚硒酸钡,研究了牦犊牛缺硒病的防治。结果表明,给牦犊牛皮下注射5～10mgSe/ml/只氢氧化铝亚硒酸钡48小时,血硒(Se)开始升高,体血Se维持50天以上;皮下注射15～20mgSe/ml/只,10小时血Se开始升高,血Se在体内维持140天以上。同时证明了氢氧化铝亚硒酸钡能有效地防治牦犊牛缺硒病,预防率92.9％～96.3％,治愈率100％。

Prevention and treatment of selenium(Se) deficiency in yak calves by subcutaneous injection of barium selenite-aluminum hydroxide (BSAH) were studied.The results showed 48 hours after BSAH had been injected into affected yak calves at the dose of 5 to 10mg Se/ml, the blood Se levels began to rise and were maintained for over 50 days; in 10 hours post subcutaneous injection at the bose of 15 to 20 mg Se /ml, the blood Se levels began to rise and were maintained for over 140 days.This test also proved Se deficiency in yak calves can be contro-led effectively with BSAH, which preventive rates ranged from 92.9% to 96.3% and the cure rates were 100%.
