Selenium yeast improves egg production performance by increasing antioxidant capacity, reproductive hormone levels and yolk precursor synthesis in late peak laying hens.

ABSTRACT: This study investigated the effects of dietary SY to supplementation on the production performance, reproductive hormones, antioxidant capacity and yolk precursor synthesis in laying hens during the late peak laying period. A total of 448 Hy-Line Brown hens (50 weeks old) were randomly assigned to four groups (basal diet supplemented with 0,0.15,0.30, and 0.45 mg/kg SY) with 7 replicates per treatment and 16 hens per replicate. The experiment consisted of a 10-day pre-trial period, followed by a 56-days trial period. The results showed that hens receiving 0.30 mg/kg SY exhibited a significantly higher laying rate compared with the CON (P < 0.05), with the selenium content in eggs also increasing linearly with increasing amounts SY (P < 0.05). Similarly, dietary SY markedly enhanced antioxi
