Diet can influence both the qualitative and quantitative traits of ruminant meat. This study evaluated the effects of castor de-oiled cake on the meat of mixed-breed male goat kids. After 165days of diet treatment, no alterations (p>0.05) were observed in the in vivo performance, anatomic components, dissection and proximate composition of the Longissimus dorsi muscle, as well as in the color and pH of the carcasses. However, diet had an effect (p<0.05) on energy metabolites, fatty acid profile, and expression of certain proteins of the Longissimus dorsi muscle. To conclude, this study showed that the establishment of castor de-oiled cake diet for a long period to goats led to alterations in meat quality, without compromising its consumption qualities.
饮食会影响反刍动物肉的质量和数量特征。本研究评估了蓖麻脱油饼对混种雄性山羊羔肉的影响。经过165天的饮食处理后，在活体性能、解剖成分、背最长肌的解剖和近似成分以及胴体的颜色和pH值方面未观察到变化（p>0.05）。然而，饮食对能量代谢物、脂肪酸谱以及背最长肌某些蛋白质的表达有影响（p<0.05）。总之，本研究表明，长期给山羊投喂蓖麻脱油饼日粮会导致肉质发生变化，但不影响其食用品质。
