摘要
本文以长×大二元断奶仔猪为对象,研究不同营养水平日粮对断奶仔猪胴体及肉质的影响。试验结果表明:高能高蛋白组、低能高蛋白组及标准营养组的日增重、料重比及胴体瘦肉率与其它各营养水平组之间差异显著(P<0.05);高能高蛋白组与低能高蛋白组的眼肌面积显著高于高能低蛋白组、低能低蛋白组与标准营养组(P<0.05);高能高蛋白组与低能高蛋白组的肌肉失水率显著高于高能低蛋白组、标准营养组与低能低蛋白组(P<0.05);高能高蛋白组及低能低蛋白组的pH24显著低于其它三个处理组(P<0.05);5个营养水平组间的肌肉嫩度、pH1没有显著差异(P>0.05)。
Taking the dual (landrace×yorkshire) weaned piglets as the object, the effects of different nutritional level diet on the dressed carcass and meat quality to weaned piglet were studied in the article.The experimental result showed that the daily gain, the feed to gain ratio and the carcass lean-percentage among the high-energy and high-protein, the low-energy and high-protein and the standard nutritional group were remarkable difference (P〈O.05) with other nutritional level groups; the loin eye muscle area between the high-energy and high-protein group and the low-energy and high-protein group was significantly higher than the high-energy and low-protein group, the low-energy and low-protein group and the standard nutritional group (P〈0.05); the muscle water loss rate between the high-energy and high-protein group and the low-energy and high-protein group was significantly higher than the high-energy and low-protein group, the standard nutritional group and low-energy and low-protein(P〈 0.05); the pH24 in the high-energy and high-protein group and the low-energy and high-protein group was significantly lower than other 3 treatments (P〈0.05); the muscle tenderness and ph1 had no significant difference among 5 nutritional level groups (P〉 0.05).
