Optimal dietary vitamin B1 content enhanced egg production, eggshell thickness, and serum antioxidant status in breeder geese.

ABSTRACT:

Objective

This study aimed to evaluate the effects of vitamin B1 (VB1) supplementation on laying performance, egg quality, serum biochemical parameters, antioxidant status, and nutrient digestion in breeder geese.

Methods

A total of 150 geese (30 males and 120 females, aged 34 weeks) were randomly assigned to 6 dietary treatment groups, each 5 replicates of 5 birds (1 male and 4 females). The geese were fed a basal diet supplemented with 0 (control), 1, 2, 3, 4, or 5 mg/kg of VB1 for 10 weeks.

Results

VB1 supplementation had no significant effects on average feed intake, average egg weight, feed-to-egg ratio, egg shape index, eggshell strength, protein height, and Haugh unit (p>0.05). However, it increased egg-laying rate, eggshell thickness, and yolk color (p<0.05) i
