酶解蛋白肽对生长育肥猪生长性能、血液生化指标及养分表观消化率的影响
Effect of Protein Hydrolysate on Growth Performance,Blood Biochemical Indexes and Nutrient Apparent Digestibility in Growing-finishing Pigs
摘要
Abstract
This experiment was aimed to study the effects of protein hydrolysate on growth performance,blood biochemical indexes and nutrient apparent digestibility in growing-finishing pigs,and determine the optimum dosage of additions.300 Doroc pig × Landrace pig × Yorkshire pig crossbreeding commercial pigs were chosen and divided into five groups with four repeats per groups and 15 pigs per repeat.The pigs in group Ⅰ(control group)were fed with basal diet,others in groups Ⅱ to Ⅴ were fed basal diet with 1％,2％,3％and 4％T30 small peptide,respectively.The test lasted for 30 d.The results showed that:①The average daily gain(ADG)of group Ⅲ was significantly higher than groups Ⅰ and Ⅴ(P<0.05),the average daily feed intake(ADFI)of group Ⅲ was significantly higher than group Ⅱ,and had no significant difference with other groups(P>0.05).②The total protein and globulin levels of group Ⅴ were the highest that significantly higher than group Ⅱ(P<0.05),and had no significant difference with other groups(P>0.05).The urea nitrogen of group Ⅱ was significantly lower than other groups(P<0.05).③The dry matter and crude protein apparent digestibility of group Ⅴ were the highest,and the Ca and P apparent digestibility were declined in T30 supplement groups.In conclusion,the optimum adding amount of protein hydrolysate of growing pig was 1.796％.It could improve the growth performance,decrease F/G,and increase the levels of total protein and globulin.关键词
