| 摘 要： | 将30只敖汉细毛羊公羊(5月龄)分为5个处理组,维生素E添加量分别为0、202、00、1 000、2 400IU/(只.d)。预试1个月,正试5个月后每组随机选3只进行屠宰,其余继续饲喂至12个月后屠宰。屠宰羊只取背最长肌和臀肌按常规法进行肉品质测定。结果表明:添加水平对臀肌pH有显著影响(P<0.05),维生素E添加组pH高于未添加组,但添加水平和时间对背肌pH及添加时间对臀肌pH影响均不显著(P>0.05);维生素E添加水平和时间对熟肉率影响未达到显著(P>0.05);滴水损失在不同添加水平下差异极显著(P<0.01),添加组均低于未添加组,200IU/(只.d)组最低,且添加12个月的滴水损失大于5个月的,添加时间对其影响显著(P<0.05);日粮不同维生素E水平对眼肌面积没有显著影响(P>0.05),但饲喂12个月后眼肌面积极显著高于饲喂5个月的(P<0.01)。综上,日粮添加维生素E可以降低肌肉滴水损失,改善羊肉肉品质,并以添加200 IU/(只.d)的效果较好,添加5个月的肉品质优于12个月的。

| Abstract: | To investigate the effect of vitamin E(VE) on meat quality,thirty male Aohan fine-wool sheep(5 months of age) with similar body weight were divided randomly into one control and four treatments,which were supplemented with 0,20,200,1000,2400 IU/(sheep d) Vitamin E,respectively.Three sheep in each group were selected randomly to slaughter after feeding VE for 5 months,the rest were slaughtered after feeding for 12 months to collect the gluteus and longissimusdorsi for meat quality measurement.The results sho... |
