摘要

本试验旨在研究低温(1~7 ℃)环境下饲粮硒(Se)添加水平对产蛋初期(120~155日龄)蛋鸭生殖器官发育及相关激素分泌的影响。试验选用120日龄金定鸭(母)216只,随机分为6组,每组6个重复,每个重复6只鸭。对照组饲喂玉米-豆粕型基础饲粮,试验组分别在基础饲粮中添加0.08、0.12、0.20、0.41、0.71 mg/kg硒。试验期5周。结果表明:1)与对照组相比,饲粮添加0.20 mg/kg硒可显著提高血清促卵泡生成激素(FSH)、促黄体生成激素(LH)、孕酮(P4)含量和卵巢指数(P<0.05),但不同水平硒对输卵管长度指数和各级卵泡数影响不显著(P>0.05);2)饲粮添加0.20 mg/kg硒可显著降低血清三碘甲腺原氨酸(T3)和皮质醇(Cort)含量(P<0.05),但不同水平硒对血清甲状腺素(T4)含量影响不显著(P>0.05)。由此可见,在本试验条件下,低温环境下蛋鸭饲粮中添加0.20 mg/kg硒可促进初产蛋鸭生殖器官发育和性激素分泌,并能辅助调节机体内分泌活动,对寒冷应激有一定程度的缓解作用。

Abstract

The experiment was conducted to study the effects of selenium (Se) supplementation on reproductive organ development and relative hormone secretion of primiparous laying ducks aged from 120 to 155 days at low ambient temperatures (1 to 7 ℃). Two hundred and sixteen 120-day-old Jinding ducks (female) were randomly allotted to 6 groups with 6 replicates per group and 6 ducks in each replicate. Ducks in control group were fed a basal diet, and the others in experimental groups were fed the basal diet supplemented with 0.08, 0.12, 0.20, 0.41 and 0.71 mg/kg Se, respectively. The experiment lasted for 5 weeks. The results showed as follows: 1) compared with the control group, adding 0.20 mg/kg Se significantly increased the contents of follicle-stimulating hormone, luteinizing hormone, progesterone in serum and the ovarium index (P<0.05), but there were no significant effects on oviduct length index and number of ovarian follicles in all groups (P>0.05). 2) Adding 0.20 mg/kg Se significantly decreased the contents of triiodothyronine and cortisol in serum (P<0.05), but different levels of Se had no significant effect on the thyroxin content in serum (P>0.05). In conclusion, under the condition of the experiment, adding 0.20 mg/kg Se can promote genital organ development and gonadal hormone secretion, regulate endocrine and reduce adverse effects of cold stress on primiparous laying ducks.
