草原红牛及其导入利木赞血牛肉质营养比较研究

Comparative Study on Beef Quality and Nutrition of China Steppe Red Cattle Crossbred With Limousin

从同一饲养条件下持续育肥的屠宰牛中，分别取草原红牛和含1／4、1／2利木赞血的草原红牛各4头牛背最长肌样品，对肉的常规营养、脂肪酸、氨基酸进行测试与分析，结果表明：除蛋白质、脂肪和油酸含量草原红牛与含1／2利木赞血的草原红牛间有规律的一定变化外，其余各项均变化不大；而草原红牛与1／4利木赞血的草原红牛间所有指标基本相同。总体来看，导入利木赞血后对草原红牛的肉质营养及风味没有不利的影响。

Under the same feeding conditions, 12 young bulls calves of China Steppe Red Cattle, China Steppe Red Cattle with 1/4 and 1/2 limousin were divided into 3 groups with 4 calves in each group. The nutrients, fatty acids, and amino acids of longissimus dorsi samples from 3 groups were analyzed. The results showed that there was no significant difference between China Steppe Red Cattle and 1/4, 1/2 crossed cattle. To sum up, there were no adverse effect on the quality and nutrition of meat of China Steppe Red Cattle crossed with limousin.
