摘　　要：本试验旨在研究饲喂不同比例的红枣-棉粕精补料替代玉米-豆粕对哺乳期驴驹生长发育及血清指标的影响。采用单因素试验设计,选取1月龄左右驴驹24头(公14头,母10头),随机分为3组,每组8头,分别为对照组(饲喂100%玉米-豆粕)、试验Ⅰ组(饲喂50%红枣-棉粕和50%玉米-豆粕)、试验Ⅱ组(饲喂100%红枣-棉粕)。预试期7 d,正试期56 d。结果显示:1)与对照组相比,饲喂50%和100%红枣-棉粕对驴驹体重、体尺和采食量无显著影响(P>0.05),对驴驹血脂和血液蛋白含量无显著影响(P>0.05)。2)与对照组相比,饲喂50%红枣-棉粕极显著增加驴驹血清超氧化物歧化酶活性(P<0.01),显著增加免疫球蛋白M(IgM)含量(P<0.05),有提高血清生长激素含量的趋势(0.05<P<0.10),且显著降低血清丙二醛含量(P<0.05)。3)与对照组相比,饲喂100%红枣-棉粕显著增加血清中葡萄糖和IgM含量(P<0.05)。综上所述,红枣-棉粕精补料可部分替代玉米-豆粕用于哺乳期驴驹,可增强驴驹抗氧化能力,提升免疫功能,促进其生长发育,以50%替代比例为佳。The objective of this experiment was to study the effects of feeding concentrate supplements containing different proportions of jujube-cotton meal on the growth and development and serum indices of donkey foals.Using single factor experimental design,24 donkey foals(14 males,10 females)(one month old)were selected and randomly divided into 3 groups,each group had 8 heads:the control group(feeding 100%corn-soybean meal supplement),test group 1(feeding 50%jujube-cotton meal and 50%corn-soybean meal supplement),and test group 2(feeding 100%jujube-cotton meal supplement).Each group had 8 head foals.The adjustment period was 7 days and the formal period was 56 days.The results showed as follows:1)feeding 50%or 100%jujube-cotton meal concentrate supplements had no significant effects on the body weight,body size and feed intake of foals(P>0.05).Feeding 50%or 100%jujube-cottonseed meal concentrate supplements had no significant effects on the serum lipid and protein contents of foals(P>0.05).2)Compared with the control group,feeding 50%jujube-cottonseed meal concentrate supplements significantly increased the serum superoxide dismutase activity(P<0.01),significantly increased the content of immunoglobulin M(IgM)(P<0.05),tended to increase the serum growth hormone content(0.05<P<0.10),and significantly decreased the serum malondialdehyde content(P<0.05).3)Compared with the control group,feeding 100%jujube-cotton meal supplement increased the glucose and immunoglobulin M contents in serum of foals(P<0.05).It can be concluded that jujube-cotton meal concentrate supplement can replace corn-soybean meal supplement to feed suckling foals,which can increase the antioxidant capacity and immune function,and has a potential to promote their growth and development.The proper replacement proportion of jujube-cotton meal supplement is 50%.
