| 摘 要： | 试验选用108头鲁农2号生长猪(49.58±1.49)kg,随机区组,分为3个处理组,每处理4个重复,每重复(圈)9头猪,在保持日粮消化能/粗蛋白质比例不变的情况下,分为高、中、低3个营养水平组,研究日粮不同消化能和粗蛋白质水平对鲁农2号生长猪屠宰性能和肉品质的影响。试验分50～80 kg和80～100 kg两个体重阶段饲养,当试验猪平均体重达到100 kg时进行屠宰,测定屠宰性能和肉品质。结果表明:3个处理组的背膘厚、眼肌面积、后腿重、后腿比例、脂肪率、屠宰率和瘦肉率均差异不显著(P>0.05);除大理石纹外,3个处理组的肉品质差异也不显著(P>0.05)。这预示着低能量和粗蛋白质日粮饲喂鲁农2号生长猪可以获得与高能量粗蛋白质日粮相近的屠宰性能和肉品质。

| Abstract: | The experiment was conducted to determine the effects of feeding three different levels of dietary digestive energy(DE)and crude protein(CP) on carcass and meat quality of Lunong 2 growing-finishing pigs.One hundred and eight growing-finishing pig were randomly assigned to three treatments,4 replications of each treatment with 9 pigs per replication.Pigs were fed with corn-soybean meal basal diets with different DE and CP levels.At the end of feeding trial,one pig(Body weight was approached to average of th... |
