摘要:

旨在研究饲粮添加三种不同大豆异黄酮(SIF)产品对产蛋后期蛋鸡产蛋性能、蛋品质、血清指标、卵巢功能和胫骨质量的影响。试验选取产蛋率相近的66周龄海兰褐蛋鸡432只,随机分为4个处理组,每组6个重复,每个重复18只鸡。对照组饲喂基础饲粮,试验组在基础饲粮中分别添加1种大豆异黄酮产品,即SIF1、SIF2、SIF3。预试期1周,正试期8周。结果表明:1)与对照组相比,饲粮中添加SIF1和SIF3可显著提高1~4、5~8和1~8周的产蛋率(P < 0.05);2)与对照组相比,饲粮中添加SIF1和SIF3可显著提高第4周和第8周鸡蛋的哈氏单位(P < 0.05),饲粮添加SIF1可显著提高第8周鸡蛋的蛋白高度(P < 0.05);3)与对照组相比,饲粮中添加SIF1可显著降低血清MDA含量(P < 0.05),饲粮中添加SIF1和SIF3可显著提高血清中GSH-Px含量和E2含量(P < 0.05),饲粮中添加SIF3可显著增加血清P4含量和血清Ca含量(P < 0.05);4)与对照组相比,饲粮中添加SIF2和SIF3可显著增加卵泡总数、初级卵泡数、次级卵泡数和小白卵泡数(P < 0.05);5)与对照组相比,饲粮中添加SIF1、SIF2和SIF3可显著提高胫骨钙和磷含量(P < 0.05)。综上,SIF可能通过增加卵巢卵泡数量,提高血清抗氧化能力、生殖激素含量和胫骨钙磷含量,进而改善产蛋后期蛋鸡生产性能和鸡蛋品质,不同SIF产品的改善效果有所差异。

Abstract:

This experiment aimed to investigate the effects of three different kinds of soybean isoflavone (SIF) supplemented in diet on laying performance, egg quality, serum indexes, ovarian function and tibia quality of laying hens in late laying period. A total of 432 66-week-old Hyline brown laying hens with similar laying rate were randomly divided into 4 treatment groups with 6 replicates per group and 18 hens per replicate. The control group was fed a basal diet, the three experimental groups were fed the basal diet supplemented with one of the three soybean isoflavone products, respectively, namely SIF1, SIF2 and SIF3. The pre-trial period was 1 week and the trial period was 8 weeks. The results showed that: 1) Compared with the control group, dietary supplemented with SIF1 and SIF3 significantly increased the laying rate at weeks 1-4, 5-8 and 1-8 (P < 0.05); 2) Dietary supplemented with SIF1 and SIF3 significantly increased the Haugh unit at weeks 4 and 8 (P < 0.05) and dietary SIF1 significantly increased the egg protein height at week 8 (P < 0.05) compared to the control group; 3) Compared with the control group, dietary supplemented with SIF1 significantly decreased serum MDA content (P < 0.05), dietary SIF1 and SIF3 significantly increased the content of GSH-Px and E2 in serum (P < 0.05), dietary SIF3 supplementation significantly increased serum P4 content and serum Ca content (P < 0.05); 4) Dietary supplemented with SIF2 and SIF3 significantly increased the total number of follicles, the number of primary follicles, the number of secondary follicles, and the number of small white follicles (P < 0.05); 5) Dietary supplemented with SIF1, SIF2 and SIF3 significantly increased the content of calcium and phosphorus in tibia (P < 0.05). In conclusion, SIF may improve the performance and egg quality of laying hens in the late laying period by increasing the number of ovarian follicles, increasing the serum antioxidant capacity, the content of reproductive hormones and the content of calcium and phosphorus in tibia, and the improvement effects of different SIF products are different.
