AB  - This experiment aims to study the effects of dietary selenium (Se) sources on the 
      production performance, reproductive performance, and maternal effect of breeder 
      laying hens. A total of 2,112 Hyline brown breeder laying hens of 42 wk of age 
      were selected and randomly divided into 3 groups, with 8 repeats in each group 
      and 88 chickens per repeat. The sources of dietary Se were sodium selenite (SS, 
      added at 0.3 mg/kg), L-selenomethionine (L-SM, added at 0.2 mg/kg), and 
      combination of SS and L-SM (SS 0.15 mg/kg + L-SM 0.15 mg/kg). The pretest period 
      was 7 d, and the breeding period was 49 d. Compared with 0.3 mg/kg SS, the 
      addition of 0.2 mg/kg L-SM in the diet significantly increased the hatchability 
      (P < 0.05) and the Se content (P < 0.05) in egg yolk and chicken embryo tissues 
      and improved the activity of yolk glutathione peroxidase (GSH-px) effectively 
      (P < 0.05). Treatment with 0.2 mg/kg L-SM also reduced the content of yolk 
      malondialdehyde (P < 0.05) and significantly improved the antioxidant performance 
      of 1-day-old chicks, as manifested by increased activity of antioxidant enzymes 
      (GSH-px, total antioxidant capacity and the ability to inhibit hydroxyl radicals) 
      in serum, pectoral, heart, and liver (P < 0.05). This treatment decreased the 
      malondialdehyde content (P < 0.05) and increased the expression of liver 
      glutathione peroxidase 4 and deiodinase 1 mRNA (P < 0.05). Adding L-SM to the 
      diets of chickens increased the hatchability of breeder eggs as well as the 
      amount of Se deposited and antioxidant enzyme activity in breeder eggs and 
      embryos. Compared with SS, L-SM was more effectively transferred from the mother 
      to the embryo and offspring, showing efficient maternal nutrition. For breeder 
      diets, the combination of organic and inorganic Se (0.15 mg/kg SS + 0.15 mg/kg 
      L-SM) is an effective nutrient supplementation technology program for effectively 
      improving the breeding performance of breeders and the antioxidant performance 
      and health level of offspring chicks.
