摘要
试验共使用84头杜长大试猪,研究按理想可消化氨基酸模式利用不同蛋白源配制的基础饲粮对生长肥育猪生产性能的影响。试验结果:豆粕+鱼粉、豆粕、豆粕+棉粕+莱粕3种不同蛋白源构成的基础饲粮,无论生长期、肥育期还是生长肥育全期日增重差异均不显著(P>0．05),采食量和饲料/增重比也很接近,肥育猪的瘦肉率和背膘厚等指标无大的差异。但豆粕+棉粕+菜粕日粮较豆粕+鱼粉日粮千克增重饲料成本低4．63%。表明,按理想可消化氨基酸模式利用非常规蛋白源配制生长肥育猪饲粮,可达到常规高品质蛋白源相似的饲养效果,并可降低饲料成本。
Eighty four pigs were used to examine effects of three diefs formulated with different protein resources according to ideal digestible amino acid pattern on performance of growing-finishing pigs and economic benefits. The results showed as follow: differencs in average daily gain (ADG) for growing, finishing, and whole growing-finishing period were not significant (P > 0.05), and the feed conversion rate (F/G), average daily feed intake (ADFI), and carcass characteristics were similar among different formula; the feed cost per kilogram gain for soybean meal-cottonseed meal-rapeseed meal diet was lower than that for soybean meal-fish meal diet by 4.63% . The data shows that diets formulated with different protein resources according to ideal digestible amino acid pattern for growing-finishing pigs are practicable in the matter of performance and economy.
