试验研究了维生素E(VE)和B族维生素(VB)对杂交商品猪的生长肥育性能及胴体肉品质的影响。结果表明,每100 kg日粮中添加45 g VB和20 g VE的2个试验组日增重。分别比对照组提高43.7 g(p<0.05)和29.8 g(p<0.05),料重比较对照组有降...试验研究了维生素E(VE)和B族维生素(VB)对杂交商品猪的生长肥育性能及胴体肉品质的影响。结果表明,每100 kg日粮中添加45 g VB和20 g VE的2个试验组日增重。分别比对照组提高43.7 g(p<0.05)和29.8 g(p<0.05),料重比较对照组有降低的趋势(p>0.05)。VE和VB对试验猪的胴体肉品质都有改善作用,与对照组相比,眼肌面积VB组提高17.29%;背膘厚VE组降低23.13%;瘦肉率VE组和VB组分别提高10.36%(p<0.05)和4.62%(p>0.05)。肉色和大理石纹评分VE组分别提高18.87%、30%;失水率VE组降低48.47%;肌内脂肪VE组和VB组分别提高25%、23.93%。利用综合选择指数进行综合评定结果显示,VE对试验商品猪的生长肥育性能和肉质改良效果最好。展开更多
In this review, the carcass, meat quality, internal organs, basic nutrition component, amino acids （AAs）, fatty acids, inosine monophosphate （IMP） and mus- cle fiber of Tibetan swine were summarized for the first ...In this review, the carcass, meat quality, internal organs, basic nutrition component, amino acids （AAs）, fatty acids, inosine monophosphate （IMP） and mus- cle fiber of Tibetan swine were summarized for the first time. The formation mecha- nism of excellent features was analyzed from the aspects of physiological traits, ge- ographical environments and constraint reasons. Thereby, the outstanding features of Tibetan swine could be extended continuously, and the poor characteristics should be improved in the future.展开更多

A total of three-way crossbred （LWD） 100 pigs were used in a completely randomized design to study the influence of rearing condition, in the growing finishing period, the initial weight, finial weight, live weight, total feeding days, daily weight gain and total feed consumptions affected carcass traits and meat qualities. In conclusion, the rearing condition will give a significant effect on pork and carcass quality so that they can be controlled by changing the raising situation.展开更多

A total of 420 day-old ducklings were divided into four treatments （seven replicates/treatment, 15 birds/replicate） by strains （A and B） and gender （male and female） in a 2 × 2 factorial arrangement under complete randomized design. The body weight （BW） of female KND was higher at week 2 and for male it was higher in week 8 （P 〈 0.05）. BW gain, feed intake and feed conversion ratio of male KND were higher than those of female KND （P 〈 0.05） during week 0 to week 8. The carcass yield of both strains increased from 6 weeks to 8 weeks （P 〈 0.05）. The breast meat ratio was the highest at week 8 whereas the leg meat ratio was the highest at 6 weeks of age in both strains （P 〈 0.01）. Lightness （L＊）, yellowness （b＊） and juiciness of meat were the highest at 6 weeks （P 〈 0.05）. Moisture, ash and fat contents of meat were the highest at 7 weeks （P 〈 0.05） and protein content was the highest at 8 weeks （P 〈 0.01）. These results may provide the basic data on growth performance and meat quality of large-type KND, which can be used for genetic improvements and rearing at commercial scale.展开更多
