| 摘 要： | 选择东北细毛羊×德国肉用美利奴的杂交一代肉羊12只,分成对照组、试验Ⅰ组和Ⅱ组,每组4只,研究谷胱甘肽对肉羊生长性能、屠宰性能及肉品质的影响。试验期60 d。结果表明:与对照组相比,谷胱甘肽显著提高了肉羊的日增重(P<0.05),试验Ⅰ组、Ⅱ组分别提高了14.6%和11.4%;降低了肉羊的料重比(P<0.05),试验Ⅰ组、Ⅱ组分别降低了11.0%和8.1%。试验Ⅰ组的净肉率和GR值显著高于对照组(P<0.05),Ⅱ组的宰前活重显著高于对照组(P<0.05);试验Ⅰ组肉的剪切力显著低于对照组(P<0.05);试验Ⅰ组、Ⅱ组的滴水损失显著低于对照组(P<0.05),而熟肉率显著高于对照组(P<0.05),且两试验组间差异不显著(P>0.05);各试验组宰后45 min内肉的pH没有显著差异(P>0.05),但试验Ⅰ组24 h的pH极显著地高于其他2组(P<0.01)。

| Abstract: | The effects of glutathione on growth performance,carcass traits and meat quality of meat sheep had been studied in this paper.Twelve F1 crossbred of German Mutton Merino Sheep with Northeast Fine-wool Sheep were chosen in the current experiment,and the animals were divided into 3 groups: control,treatmentⅠ and Ⅱ,with 4 replicates in each treatment.Animals were fed for 60 days.The results indicated that: compared with the control,the average daily gain increased in treatmentⅠand Ⅱ(P<0.05)by 14.6% and 11.4%,and feed to gain rate decreased by 11.0% and 8.1%,respectively(P<0.05);there were higher net meat rate and GR value in treatmentⅠ(P<0.05)and live body weight in treatmentⅡ(P<0.05);and shear stress of treatmentⅠ,drip loss of treatmentⅠand Ⅱdecreased significantly(P<0.05).There was no significant difference in cooking rate between treatmentⅠand treatment Ⅱ(P>0.05),but significant increase in these two treatments compared with control(P<0.05).There were no significant differences in meat pH at 45-min post-slaughter among three groups(P>0.05),but significant increase in meat pH at 24-h poat-slaughter in treatmentⅠcompared with the control(P<0.01). |
