摘要
试验旨在研究日粮中添加不同比例的全株发酵杂交构树替代豆粕对育肥猪生长性能、胴体性状、肉品质和养分表观消化率的影响。选择48头初重(60.44±2.51) kg、健康的“杜×长×大”三元杂交育肥猪,随机分为4组,每组3个重复,每个重复4头猪。A组(对照组)育肥猪饲喂基础日粮,B组、C组、D组育肥猪分别饲喂使用3%、5%、7%全株发酵杂交构树替代豆粕的试验日粮。预试期10 d,正式试验期45 d。结果显示,与A组相比,B组育肥猪的平均日增重增加了2.78%(P>0.05);各试验组育肥猪的眼肌面积、肌内脂肪、蛋白质含量均显著升高(P<0.05);C组、D组育肥猪对日粮酸性洗涤纤维、粗脂肪、中性洗涤纤维、钙、磷的表观消化率均显著升高(P<0.05)。研究表明,使用3%全株发酵杂交构树代替豆粕对育肥猪的生长性能、肉品质和表观消化率的影响作用较好。
The experiment was to study the effect of replacing soybean meal with different proportions of whole plant fermentated hybrid tree on growth performance,carcass traits,meat quality and nutrient apparent digestibility of finishing pigs.A total of 48 healthy'Duroc×Landrace×Yorkshire'crossbred finishing pigs with an initial weight of(60.44±2.51)kg were randomly divided into four groups,with three replicates in each group and four pigs in each replicate.The finishing pigs in group A(control group)were fed with basal diet,and the finishing pigs in group B,group C and group D were fed with experimental diet with 3%,5%and 7%whole fermented hybrid tree instead of soybean meal,respectively.The pre-test lasted for 10 d,and the formal test lasted for 45 d.The results showed that compared with group A,the average daily gain of finishing pigs in group B was increased by 2.78%(P>0.05),the eye muscle area,intramuscular fat content and protein content of finishing pigs in experimental groups were significantly increased(P<0.05).The apparent digestibility of acid detergent fiber,crude fat,neutral detergent fiber,calcium and phosphorus in diets of finishing pigs in group C and group D were significantly increased(P<0.05).The experiment indicates that using 3%whole plant fermented hybrid tree instead of soybean meal has better effect on growth performance,meat quality and apparent digestibility of finishing pigs.
