Influence of Dietary Selenomethionine Supplementation on Performance and Selenium Status of Broiler Breeders and Their Subsequent Progeny

Abstract

The study was conducted to investigate the effects of dietary maternal selenomethionine or sodium selenite supplementation on performance and selenium status of broiler breeders and their next generation. Two hundred and forty 39-week-old Lingnan yellow broiler breeders were allocated randomly into two treatments, each of which included three replicates of 40 birds. Pretreatment period was 2 weeks, and the experiment lasted 8 weeks. The groups were fed the same basal diet supplemented with 0.30 mg selenium/kg of sodium selenite or selenomethionine. After incubation, 180 chicks from the same parental treatment group were randomly divided into three replicates, with 60 birds per replicate. All the offspring were fed the same diet containing 0.04 mg selenium/kg, and the experiment also lasted 8 weeks. Birth rate was greater (p < 0.05) in hens fed with selenomethionine than that in hens fed with sodium selenite. The selenium concentration in serum, liver, kidney, and breast muscle of broiler breeders, selenium deposition in the yolk, and albumen and tissues' (liver, kidney, breast muscle) selenium concentrations of 1-day-old chicks were significantly (p < 0.01) increased by maternal selenomethionine supplementation compared with maternal sodium selenite supplementation. The antioxidant status of 1-day-old chicks was greatly improved by maternal selenomethionine intake in comparison with maternal sodium selenite intake and was evidenced by the increased glutathione peroxidase activity in breast muscle (p < 0.05), superoxide dismutase activity in breast muscle and kidney (p < 0.05), glutathione concentration in kidney (p < 0.01), total antioxidant capability in breast muscle and liver (p < 0.05), and decreased malondialdehyde concentration in liver and pancreas (p < 0.05) of 1-day-old chicks. Feed utilization was better (p < 0.05), and mortality was lower (p < 0.05) in the progeny from hens fed with selenomethionine throughout the 8-week growing period compared with those from hens fed with sodium selenite. In summary, we concluded that maternal selenomethionine supplementation increased birth rate and Se deposition in serum and tissues of broiler breeders as well as in egg yolk and egg albumen more than maternal sodium selenite supplementation. Furthermore, maternal selenomethionine intake was also superior to maternal sodium selenite intake in improving the tissues Se deposition and antioxidant status of 1-day-old chicks and increasing the performance of the progeny during 8 weeks of post-hatch life.

Selenium in poultry nutrition: a review

“…The antioxidant status of 1-day-old chicks was greatly improved by maternal Se-Met intake in comparison with maternal sodium selenite intake and was evidenced by the increased GSH-Px activity in breast muscle, superoxide dismutase activity in breast muscle and kidney, glutathione concentration in kidney, total antioxidant capability in breast muscle and liver, and decreased malondialdehyde concentration in liver and pancreas of 1-day-old chicks (Wang et al 2011a). …”

Selenium‐enriched Saccharomyces cerevisiae improves growth, antioxidant status and selenoprotein gene expression in Arbor Acres broilers

“…In the present study, we found that SSC and SS supplementation increased the final body weight and decreased the feed/gain ratio, but did not increase the average daily weight gain. Mahmoud and Edens (2003), Wang and Xu (2008) and Wang et al (2011) reported that Se supplementation remarkably improved the average daily weight gain and the feed conversion ratio of broiler chickens and rabbits. In contrast, some reports indicated that Se supplementation did not influence the growth of broilers (Yoon et al, 2007;Baowei et al, 2011) and lambs Vignola et al, 2009).…”

Meta-analysis of selenium accumulation and expression of antioxidant enzymes in chicken tissues

“…Se originating from B-Traxim accumulates to a greater extent in lipid-associated components such as yolk (Leeson et al, 2008). Se, in common with many other minerals, may be preferentially deposited in the yolk compared with the albumen, which is a consequence of the activity of mineral-binding lipoproteins in the formation of the egg yolk (Pappas et al, 2005b;Wang et al, 2011a). The quantity of Se added may have a role on Se partitioning in egg components.…”
