Abstract
- Serum caeruloplasmin (ferroxidase I;EC 1.16.3.1) activity has been used as an indicator of copper status of cattle to survey beef herds in Northern Ireland. 2. The main survey covered some 20 000 cows on 1200 farms. 3. The results are reported in the form of a map showing area where herds of low and very-low Cu status predominate. Clinical signs of Cu deficiency in calves were encountered in only two areas.
摘要
- 血清铜蓝蛋白（亚铁氧化酶I；EC 1.16.3.1）活性已被用作牛铜状态的指标，用于调查北爱尔兰的肉牛群。2. 主要调查覆盖了1200个农场的约20000头奶牛。3. 结果以地图的形式呈现，显示低铜和极低铜状态牛群占主导的区域。仅在两个区域发现了犊牛铜缺乏的临床症状。
