| 摘 要： | 【目的】评价苜蓿草粉对肥育猪胴体品质和血液生化指标的影响。【方法】分两部分进行。试验1，选取体重约50 kg的杜×长×大三元杂交猪40头，采用单因子完全随机设计，分为5个组，每组4个重复，分别在饲粮中添加不同比例的苜蓿草粉，依次为：0（对照组）、10%（试验Ⅰ组）、15%（试验Ⅱ组）、20%（试验Ⅲ组）、20%+1%复合纤维素酶（试验Ⅳ组），测定肥育猪饲喂含不同水平苜蓿草粉饲粮后胴体品质及血液中主要生化指标的变化。试验2，选取体重约50 kg的杜×长×大三元杂交猪36头，采用单因子完全随机设计，分为3个组，每组3个重复，分别在饲粮中添加0%的苜蓿草粉和皂苷（对照组）、15%苜蓿草粉（试验Ⅰ组）、0.3%苜蓿皂苷（试验Ⅱ组），测定肥育猪血液中主要生化指标的变化。【结果】（1）试验1中，各组的眼肌面积、肉色和大理石纹基本无变化，但添加苜蓿草粉后，程度不同地降低了背膘厚、提高了屠宰率和瘦肉率，说明苜蓿草粉对胴体品质有改善，其中以10%、15%组较优。（2）试验1中，添加苜蓿草粉后，提高了血液中GH、Ins和IGF-1含量，但明显降低了血糖和血液中胆固醇的含量。（3）试验2中，肥育猪饲粮中添加苜蓿皂苷和草粉，降低了其血液甘油三酯、胆固醇及低密度脂蛋白胆固醇含量，升高了高密度脂蛋白胆固醇含量。【结论】在肥育猪饲粮中添加15%紫花苜蓿草粉对肥育猪的胴体品质和血液生化指标的改善有利，苜蓿草粉的降低血液胆固醇的功能主要是其中皂苷的作用。

| Abstract: | 40 fatting pigs, body weight about 50kg for each one,were randomly divided into 5 groups,4 replicates for each group and 2 for each replicate.One of these groups was used as the contol group,other groups were used as test groups,groupI,groupII,groupIII and groupIV.The control group was fed basic diet,groupI、II、III were fed the diets containing alfalfa meal in different level (10%、15％、20％) and groupIV was fed the diet 20％ alfalfa meal and 01% cellulase.The experimental period was 60d.The results showed:(1)Three test groups,groupII,groupIIIand groupIV,had higher daily intake and daily gain than the control group,and groupII and groupIV had higher feed conversion rate than the control group.(2)Compared with the control group,there were more apparent digestibility of nutrients for groupI、II,however,groupIII、IV had similar digestibility with the control group.The digestibility of groupIV was higher than groupIII one,showed that it was useful to add 0.1% cellulase enzyme for diet of higher amount of alfalfa meal.(3)There were no significant difference in eye muscle area,meat colour and marbling among groups,however,because of adding suitable amount of alfalfa meal,these ones,back fat thichness was dropped , killing out percentage and thin meat ratio were improved.(4)Adding alfalfa meal in fatting pig,s dietary,groupI、II、III、IV had significant improvement in GH、Ins、IGF-1 comparing with the control one,but there were significant derease in GLUand CHU.The study showed that it was best to add 15% alfalfa meal in diets of fatting pigs among all groups,so it should be recommend in diet. |
