摘要
试验选用28周龄产蛋率接近的健康如皋草鸡64只,随机分成4组,每组4个重复,每个重复4只,日粮分别含有0%、8.26%、16.52%和24.84%的葵花籽粕(ME,8.50MJ/kg;CP,33.00%;Ca,0.26%;P,1.03%),各处理日粮中能量、蛋白水平相同,试验期为42d。结果表明,不同水平葵花籽粕替代豆粕对如皋草鸡产蛋性能和试验期第14、28和42天的蛋品质均无显著影响(P>0.05);试验期内,与0%葵花籽粕组相比较,8.26%、16.52%和24.84%葵花籽粕组的耗料成本分别降低1.025、1.31和2.439元/只,16.52%和24.84%葵花籽粕组的利润分别增加0.531和1.737元/只。由此可见,葵花籽粕能够作为饲料蛋白源,有效替换豆粕。
Sixty-four 28-week-old Rugao chickens were acclimated to the basal diet for 1 week. At day 1 of the experiment,chickens were randomly assigned to 4 groups. 4 replicates each group,each with 4 chickens. Soybean meal was allocated to the control group,while experimental diets which contained 8.26%,16.52% and 24.84% sunflower seeds diet by mass were allocated to the experimental groups respectively. Food and water were offered ad libitum for 6 weeks. The results showed that, no significant difference on the performance and egg quality was found among the 4 groups （P〉0.05）. Within the experiment, the feed cost of 8.26%,16.52% and 24.84% sunflower seeds groups reduced by 1.025,1.31 and 2.439 RMB per bird, and the profit of 16.52% and 24.84% sunflower seeds groups increased by 0.531 and 1.737 RMB per bird. It was indicated that sunflower seeds diet was a well substltute,whlch could not influence the performance and egg quality of 28-week-old Rugao chickens,and in part,could increase the profit.
