| 摘 要： | 用48头八眉猪,以异速模型Y=αX~b研究了两个营养水平、初生至80kg体重阶段的肌肉化学组成的异速生长特性及其营养和性别的影响。结果表明,八眉猪肌肉蛋白质、脂肪、灰分和水分的异速生长系数(b)分别为1.049,1.375,1.078和0.978.去势公猪肌肉蛋白质b的值大于去势母猪,水分b值小于去势母猪(P<0.05),脂肪和灰分的异速生长则不受性别的明显影响。将日粮的蛋白质和能量水平分别从14.25％和13.10MJ/kg降至12.15％和11.88MJ/kg,不会明显地影响八眉猪肌肉化学组成的异速生长模式。

| Abstract: | The allometric growth of chemical composition of meat tissues at two nutrient levels and from birth weight to 80 kg of body weight and the effects of sex and nutriention on them were determined using the allometric model Y = aX}' from 48 Bamei pigs. The results showed that the allometric growth coefficients (b) of protein, fat, ash, and water of meat tissues in Bamei pigs were 1.049$ 1.375} 1.078$ and 0.978 respectively. The 6 value'of meat protein in barrows was higher (P<0.05) than that in spayed gilts, and the b value of meat water in barrows was lower (P<0.05) than that in spayed gilts. The allometric growth of meat fat and ash was not affected significantly by sex. Reducing the level of protein and energy in the diet from 14.25% and 13,01(MJ/kg) to 12.15% and 11.88(MJ/kg) respectively can not affect the allometric growth models of chemical compositions of meat tissues in Bamei pigs. |
