摘  要：
为研究不同营养水平对育肥后期三江白猪胴体指标的影响效应,试验采用二次正交旋转组合设计,以能量、蛋白质、赖氨酸为3因素,选择体重(69.74±0.87)kg的育肥后期三江白猪207头,按体重、性别一致原则,平均分成23组,其中14个试验组,9个零水平组,每组3个重复,每个重复3头猪。试验猪达100 kg时屠宰。结果表明:3因素对育肥后期三江白猪瘦肉率调节的灵敏度为:赖氨酸>蛋白质>能量;对背膘厚和眼肌面积调节的灵敏度为:能量>蛋白质>赖氨酸;在蛋白质水平为15.43%、赖氨酸水平为0.63%时,对胴体瘦肉率的互作效应最强。以零水平的能量(12.72 MJ/kg)和低水平的蛋白质(12.57%)为基点,无论2因素水平同时提高或是某一因素水平提高另一因素水平降低,其互作效应均使眼肌面积增大,且以能量、蛋白质上限互作的预测值最大。能量水平下限(11.96 MJ/kg)、赖氨酸水平下限(0.53%)时,胴体屠宰率较高,为73.41%。

摘  要：
The experiment was conducted to study the effects of different nutrient levels on the Sanjiang white pigs' carcass characteristic in the latter finishing period. Through the quadratic orthogonal rotation combination design, digestible energy (DE), crude protein (CP) and lysine (Lys) were as three factors. Two hundred and seven Sanjiang white pigs with an average weight of (69. 74 ± 0. 87) kg were randomly allocated to 23 groups with 3 replicates in each group of 3 pigs per replicate according to sex and weight in which 14 groups were experimental groups and 9 groups were zero level groups. Pigs were slaughtered at 100 kg. Results showed that the sensitivity of three factors to lean percentage of the latter Sanjiang white finishing pigs was Lys>CP>DE and the sensitivity of three factors to back fat thickness and loin-eye area were DE>CP>Lys. When the CP level was 15. 43% and the Lys level was 0. 63% , interaction effect on lean percentage was the strongest. Taking the zero level of DE (12. 72 MJ/kg) and the low level of CP (12. 57%) as base point, when the level of two factors improved both or the level of one factor improved and the other factor decreased at the same time, all of the interaction effects made loin eye area increase, and the predictive value of the interaction effect of DE and CP upper limit was maximum. When the lower limit of DE level was 11. 96 MJ/kg and the lower limit of the Lys level was 0. 53% , the higher carcass dressing percentage was 73. 41% .
