中药益生菌复合制剂对海兰褐蛋鸡生产性能及卵巢功能的影响

Effect of Chinese herbal-probiotics compounds on production performance and ovarian function of Hyline brown laying hens

试验旨在研究两种不同中药益生菌复合制剂对蛋鸡生产性能及卵巢功能的影响。选用50周龄海兰褐商品蛋鸡450只,根据体重和产蛋率相近原则,随机分成5组,每组6个重复,每个重复15只蛋鸡。对照组(CK组)蛋鸡饲喂基础日粮,F1-1组和F1-2组分别在基础日粮中添加1‰和2‰中药益生菌复合制剂一(F1,由黄芪、板蓝根、淫羊藿等中药和益生菌组成),F2-1组和F2-2组分别在基础日粮中添加1‰和2‰中药益生菌复合制剂二(F2,由当归、熟地、益母草等中药和益生菌组成)。预试期7 d,正式试验期21 d。结果显示,F1-2组蛋鸡的料蛋比显著低于CK组(P<0.05),鸡蛋的哈夫单位、蛋形指数、蛋壳厚度均得到改善。与对照组相比,F1-2组蛋鸡血清中黄体酮(P4)和促黄体素(LH)水平分别提高了77.20%、58.02%(P<0.05)。F1-2组、F2-1组和F2-2组蛋鸡血清白细胞介素-2(IL-2)含量分别比CK组降低24.54%、29.88%、27.25%(P<0.05),F1-2组蛋鸡血清免疫球蛋白G(IgG)含量比CK组提高19.64%(P<0.05)。研究表明,两种中药益生菌复合制剂均能够在一定程度上提高蛋鸡生产性能和蛋品质,促进卵巢生殖激素的分泌,减轻蛋鸡体内炎性反应,提高免疫力,以添加2‰中药益生菌复合制剂一的效果较好。

The experiment was to study the effect of two different Chinese Herbal-probiotics compounds on the production performance and ovarian function of laying hens.A total of 450 fifty-week-old Hyline brown laying hens with similar 1aying rates and body weights were randomly divided into five groups with six replicates in each group and 15 chickens in each replicate.The laying hens in the control group(CK group)were fed a basal diet,and the F1-1 group and F1-2 group were supplemented with 1‰and 2‰Chinese herbal-probiotics compound 1(F1,composed of Astragalus,Radix Isatidis,Epimedium,etc.and probiotics)in the basal diet.The F2-1 group and F2-2 group were supplemented with 1‰and 2‰Chinese herbal-probiotics compound 2(F2,composed of Angelica,Rehmannia,motherwort,etc.and probiotics)in the basal diet,respectively.The pre-test period was 7 days,and the formal test period was 21 days.The results showed that the feed to egg ratio of the F1-2 group was significantly lower than that of the CK group(P<0.05),and the Huff unit,egg shape index,and eggshell thickness of eggs have all been improved.Compared with the CK group,the serum levels of progesterone(P4)and luteinizing hormone(LH)of laying hens in the F1-2 group increased by 77.20%and 58.02%,respectively(P<0.05).Compared with the CK group,the serum IL-2 content of laying hens in the F1-2 group,F2-1 group and F2-2 group was decreased by 24.54%,29.88%and 27.25%(P<0.05),and the serum IgG content of laying hens in the F1-2 group was increased by 19.64%(P<0.05).The study indicates that two different Chinese herbal-probiotics compounds can improve the production performance and egg quality of laying hens,promote the secretion of ovarian reproductive hormones,improve the ovarian function,reduce the inflammatory reaction in laying hens,and improve immunity,and the effect of adding 2‰Chinese herbalprobiotics compound 1 is better.
