| 摘 要： | 将黄芪、当归、甘草和山楂等粉碎后按一定比例配伍制成复方中草药饲料添加剂后,按质量分数0.5%、1.0%、1.5%和2.0%添加到基础饲料中,连续投喂红笛鲷(体重234.95±19.26 g,体长24.76±1.42 cm)56 d,研究复合中草药制剂对红笛鲷生长、成活、免疫和抗病力的影响。结果表明,基础饲料中添加本复方中草药饲料添加剂能够显著促进红笛鲷的生长,增强其血清中的抗菌活力和溶菌酶活力,提高红笛鲷成活率及其对溶藻弧菌的免疫保护率,其中以添加1.5%(质量分数)和连续饲喂28 d效果为最佳(P<0.01)。

| Abstract: | Chinese herbal feed additives(CHFD) were made up of Astragalus membranaceus,Radix Angelica,Radix Glycyrrhizae and other Chinese herbs.The Lutjanus sanguineus(body weight 234.95±19.26g,body length 24.76±1.42cm) were fed for 8 weeks with medicated diet to study the effects of CHFD on the growth performance,survival,immune function and disease resistance,with Chinese herbal feed additives at different contents of 0.5%,1.0%,1.5% and 2.0%,respectively.The results showed that CHFD could significantly promote the growth of Lutjanus sanguineus,increase Lysozyme activity and antibacterial activity in serum and enhance the survival rate and relative percentage survival,especially in the treated group of 1.5% CHFD after 28 days feeding had the best effect(P<0.05). |
