摘要
为研究发酵床养猪对猪肉品质的影响,试验选择28d断奶的杜长大三元杂交仔猪60头,随机分成试验组和对照组,试验组以发酵床饲养,对照组采用常规水泥地面饲养,试验期为125d,试验结束时,每组随机抽样6头猪进行屠宰测定。试验结果:与对照组相比,试验猪日增重和饲料转化效率分别提高了8.49%和6.27%,背膘厚降低6.8%,脂率降低5.37%,腿臀比例增加6.98%,差异均为显著(P<0.05),而眼肌面积,瘦肉率,屠宰率、板油率、骨率及皮率等指标无明显差异(P>0.05),在肉品质方面,试验组猪肉的颜色、pH值、失水率、滴水损失、熟肉率等肉品质指标均有明显的改善(P<0.05)。表明了相对于水泥面饲养,发酵床养猪有明显提高猪的生长性能和猪肉品质的作用。
60 28-day-old Duroc×Landrace×Large white weaning pigs were randomly selected and divided into Experimental group and Control group to study the effect of biological fermentation bed on pork quality of growing-finishing pigs.Experimental group were raised on the fermentation bed;Control group were raised on the conventional concrete floor;the experimental period was 125 days;6 pigs from each group were selected randomly and slaughtered for determination when the experiment was finished.The results： compared with Control group,in Experimental group,average daily gain and feed conversion rate increased 8.49% and 6.27% respectively,back fat decreased 6.8%,fat rate decreased 5.37%,hind leg ratio increased 6.98%,and the difference（P0.05） was significant;the difference（P0.05） was insignificant in eyemuscle area,iean meat percentage,dressing percentage,leaf fat percentage,bone percentage,skin percentage,etc;the pork quality indexes such as meat color,PH,water loss rate,drop loss,cooked rate,etc,all had significant improvement（P0.05）.The results show that,compared with the conventional concrete floor,the fermentation bed has obvious effect on improving growth performance and pork quality of growing-finishing pigs.
