秸秆替代部分精料对肉兔生长性能、屠宰性能和肉品质的影响
Effects of Replacing Part of Concentrated Feed with Straw on Growth Performance,Slaughter Performance and Meat Quality of Meat Rabbits
摘要
Abstract
[Objective]Effects of partial replacing the refined forage with peanut straws and Chamaecrista rotumdifolia in feed on growth,slaughter performance,and meat quality of rabbits were analyzed.This study provides a theoretical basis and data support for the scientific and economical utilization of high-quality agricultural by-products in meat rabbit production.[Method]Sixty healthy 70-day-old rabbits with similar body weights were randomly divided into 5 groups with 3 replicates of two male and two female rabbits per replicate for each group.Rabbits in the control group were fed a basal diet,while those in the treatment groups given a forage that replaced 10%of the refined ingredients with straws of peanut plants of one of 4 different varieties.The varieties of peanut plants selected for the experimentation were dual-purpose Arachis hypogaea L.'Shan G'for Treatment 1,'TJ'for Treatment 2,and'Quanhua 7'for Treatment 3 as well as Chamaecrista rotundifolia'Minyu 1'for Treatment 4.The rabbits were fed for 10d in a pre-trial period prior to the experiment that lasted 45 d when the rabbit growth was monitored and,at the end,the slaughter performance and meat quality determined.[Result]Compared with control,the treatment rabbits were slightly lower,but not significantly,on the final weight,average daily gain,and average daily feed intake(P＞0.05).In the end,the meat-to-bone ratios of the slaughtered rabbits in Treatments 1,2,and 4 increased by 18.67%,14.18%and 6.71%,respectively,and the carcass drip losses in Treatments 2 and 4 significantly decreased(P＜0.05).The meat protein content of Treatments 2,3,and 4 rose,with that of Treatment 4 being significantly higher than control(P＜0.05).In the meats of all treatment rabbits,crude fiber significantly declined(P＜0.05),while crude fat reduced in varying degrees.Calcium increased significantly by 58.6%in Treatment 2(P＜0.05),phosphorus elevated in all treatments,and total amino acids reached 69.28%,72.73%,71.79%,and 74.84%in Treatments 1,2,3,and 4,respectively,in comparison to control at 68.81%.The greatest amino acid increase was found in the rabbits of Treatment 4 and followed by Treatment 2(P＜0.05).[Conclusion]Replacing refined forage with peanut straws at 10%in feeding rabbits could significantly improve the animal growth,slaughter performance,and meat quality.Overall,TJ was the chosen peanut variety to collect straws for the application.关键词
