| 摘 要： | 本试验旨在通过研究玉屏风散对育肥阉牛生产性能、屠宰性能及肉质的影响,以期探讨肉牛健康养殖技术。试验选用健康、体重相近(548+50 kg),年龄40月龄的"利×鲁"杂交一代育肥阉牛36头,随机分为四个组,分别按精料量的0%、1%、1.5%、2%添加玉屏风散,饲喂60 d,每20 d称重一次。试验60 d后将36头牛全部屠宰,然后进行屠宰测定和肉质分析。试验结果表明:在日粮中添加玉屏风散有提高育肥阉牛日增重和饲料报酬的趋势,但是并不显著(P>0.05);试验组的屠宰率、净肉率、眼肌面积、大理石花纹、高档肉占活重皆优于对照组,但是差异不显著(P>0.05);1%的玉屏风散添加组的牛肉中的粗蛋白、粗脂肪皆显著高于对照组(P<0.05),水分的含量显著的低于对照组(P<0.05);料重比与屠宰性能的许多指标都存在着一定的相关性,可通过料重比来估测育肥阉牛屠宰性能的多种指标。 |
| 关 键 词： | 玉屏风散 育肥阉牛 生产性能 屠宰性能 |

| Abstract: | This experiment was conducted to study the effect of Jade Screen Powder on performance of fattening bullocks,and the aim was to instruct the healthy cultivation of beef cattles.36 Fattening bullocks(Limousin cattle X Luxi cattle) which were healthy,about two years old and had similar weight were divided into four groups randomly.The four treatments were added with jade screen powder(0%,1%,1.5%,2% per concentrate cattle feed).All Cattles were weighed one time every 20 days.The 36 fattening bullocks were all ... |
