安格斯改良草原红牛效果的研究

Study on the Effect of Crossbred Red Cattle of Steppe Using Angu

本试验利用草原红牛和红草F1杂交牛作为试验牛种,在相同营养水平下饲养,然后进行育肥、屠宰试验。结果表明,红草F1杂交牛的屠宰率、净肉率、肉骨比较纯种草原红牛均有极显著提高(P<0.01);红草F1杂交牛的剪切力值比草原红牛的要低且差异极显著(P<0.01)。用安格斯改良草原红牛,可使草原红牛的产肉性能明显提高,改良效果较好。

This experiment used red cattle of steppe and crossbreed of Fl as material cattle, feeding in the same nutrition level, then proceeded finishing and slaughtering experiments. Average dressing percent- age ,net meat percentage and ratio of muscle to bone red steppe F1 crossbreed were significantly higher than red steppe （P〈0.01）;Shear force of F1 crossbreed＇s was significantly lower than red cattle of steppe（P〈0.0l ）. Using Angus crossbred red cattle of steppe for improving red cattle of steppe, red cattle of steppe＇s performance of meat yield has improved greatly, the effect of improvement is better.
