摘　　要： 采用综合性防治措施，对广州市国营新洲奶牛场泌乳牛群（试验牛总数为５１２头）进行为期１８个月的乳房炎防治试验研究，结果表明，奶牛临床型乳房炎病率（按临床发病例数统计）由３５．２８％（１９９１年１０月至１９９２年９月）降至２７．８９％（１９９２年１０月至１９９３年９月）；隐性乳房炎乳区发病率由３７．４２％（１９９２年４月至９月，试验前）降至２９．３４％（１９９２年１０月至１９９３年７月，试验期）；头日均奶产量从试验前（１９９１年７月至１９９２年６月）的１３．０５ｋｇ，提高到试验后（１９９２年７月至１９９３年７月）的１３．８６ｋｇ，上升６．２１％。实施奶牛乳房炎综合防治措施，对促进奶牛业生产发展有非常重要意义。 This study was carried out on Xinzhou dairy farm of Guangzhou,with a herd of 512 cows,over a duration of 18 months. Six trials were conducted to study the effect of feed protein levels,vitamin E and selenium trace elements;sodium humate,Chinese traditional medicinal herbs and levamisole;comprehensive therapy;etiological examinations and clinical therapy on mastitis.Results indicated that incidence of clinical mastitis was markedly decreased from 35.28% (Oct.1991～Sep.1992) to 27.89%(Oct.1992～Sep.1993),incidence of subclinical mastitis from 37.42%(before experiment)to 29.34%(during experiment)and the average individual milk daily production was increased from 13.05kg(before experiment)to 13.86 kg(after experiment).The results of this study suggested a comprehensive approach to mastitis control on each dairy farm might be a possible way to eliminate the disease.
