生物饲料对不同品种肉牛肉质的影响分析

牛肉具有高蛋白质,低脂肪,含磷脂多、胆固醇少,肌肉纤维细嫩、柔软,风味独特等优点。随着人们生活水平的提高和膳食结构的改变,牛肉消费量也持续增加,为牛肉生产带来了难得的发展机遇。试验研究相同饲养管理条件下,生物饲料对不同品种肉牛肉中屠宰性能和常规营养成分的影响,证明安格斯公牛在胴体重、屠宰率、净肉重、净肉率和胴体产肉率相比西杂牛更高(P<0.05);而水分、粗脂肪、粗蛋白含量也存在较大差异(P<0.05)。这能够为提高肉牛的肉质提供科学的依据,在肉牛生产中具有重要的实践指导意义。

Analysis of the Effect of Biological Feed on Different Types of Beef Meat

Beef has the advantages of high protein, low fat, more phospholipids and less cholesterol. With the improvement of people's living standards and changes in dietary structure, beef consumption has continued to increase, which has brought rare opportunities for beef production. This experiment studied the effects of biological feed on slaughter performance and conventional nutrient composition of different breeds of beef under the same feeding and management conditions, which proved that Angus bulls had high values of carcass weight, slaughter rate, net meat weight, net meat rate and carcass meat production rate, compared with Xiza cattle (P< 0.05);there were also significant differences in water, crude fat and crude protein content (P< 0.05). This can provide a scientific basis for improving the meat quality of beef cattle, and has important practical guiding significance in beef cattle production.
