The aim of this study was to investigate the effects of Enteromorpha powder supplementation on reproduction-related hormones and genes in the late laying period of Zi geese.
A total of 312 (1-year-old) Zi geese with similar laying rate were randomly divided into 2 groups with 6 replicates each, each with 21 female geese and 5 male geese. The control group was fed with a basal diet and the test group was fed with a diet containing 3% Enteromorpha powder. The trial period lasted for 7 weeks.
Our results showed that the laying rate was improved in the test group at each week of trial (p<0.01), and the levels of estradiol in serum and prolactin in ovary were increased compared with the control group (p<0.05).
Based on above results, Enteromorpha powder supplementation at 3% could promote reproductive performance during the late laying period of Zi geese.
本研究旨在探讨添加浒苔粉对籽鹅产蛋后期生殖相关激素和基因的影响。
选取312只(1岁)产蛋率相近的籽鹅,随机分为2组,每组6个重复,每组有21只母鹅和5只公鹅。对照组饲喂基础日粮,试验组饲喂含3%浒苔粉的日粮。试验期持续7周。
结果表明,试验组在试验各周的产蛋率均有所提高(p<0.01),血清雌二醇水平和卵巢催乳素水平均高于对照组(p<0.05)。
基于上述结果,添加3%浒苔粉可提高籽鹅产蛋后期的繁殖性能。
