食叶草鲜草对育肥猪生长性能、胴体性状及血液生化指标的影响
Effects of Leafy Fresh Grass on Growth Performance,Carcass Traits and Blood Biochemical Indexes of Finishing Pigs
摘要
Abstract
This study investigated the effects of adding different proportions of leafy fresh grass to the diet on the growth performance,carcass traits,and blood biochemical parameters of finishing pigs.One hundred and sixty"Duroc × Landrace × Yorkshire"crossbred finishing pigs of similar age(150 days)and weight(85±1.75 kg)were selected and randomly divided into four groups,with eight replicates per group(5 pigs per replicate).The groups were:a control group(Group 1)with 0％leafy fresh grass,and treat-ment groups with 6％(Group 2),8％(Group 3),and 10％(Group 4)leafy fresh grass supplementation.The pre-trial period was 7 days,and the trial period was 42 days.The results showed that the average daily gain of Groups 3 and 4 was increased by 15.0％and 14.5％,respectively,compared to the control group(P＜0.05),and their feed-to-gain ratio was decreased by 8.59％and 7.67％,respectively(P＜0.05).The lean meat percentage and eye muscle area of Groups 3 and 4 were increased by 15.0％,15.8％,16.5％,and 16.9％,respectively,compared to the control group(P＜0.05),while their average backfat thickness was decreased by 15.2％and 15.6％(P＜0.05).The serum total protein(TP)and globulin(GLB)levels in Groups 3 and 4 were increased by 17.9％,18.4％,13.0％,and 14.2％,respectively,compared to the con-trol group(P＜0.05),and the serum aspartate aminotransferase(AST)and blood urea nitrogen(BUN)levels were decreased by 20.4％,20.01％,10.5％,and 11.9％,respectively(P＜0.05).In conclusion,the addition of 8％leafy fresh grass can improve the growth performance and carcass traits of finishing pigs,increase lean meat percentage,and improve blood biochemical parameters as well.关键词
