    ABSTRACT: The maternal effect of different Se source in offspring of young broiler breeders has been reported, but the lasting maternal effect of different sources of Se on offspring of breeders has received limited attention, so this study was conducted to investigate the effects of different maternal Se sources on Se retention, antioxidant status, and meat quality of 56-d-old offspring of broiler breeders. A total of two hundred forty 39-wk-old Lingnan Yellow broiler breeders were randomly distributed into 2 treatments, each of which was replicated 3 times with 40 birds per replicate, with a 14-d pretreatment and 56-d trial period. The treatments were fed a basal corn-soybean diet (0.04 mg∙kg(-1) Se) supplemented with 0.3 mg∙kg(-1) sodium selenite (SS) or selenomethionine (Se-Met). Fertile eggs were collected for incubation, after which 180 healthy chicks from each treatment were selected and randomly allocated into 3 replicates, with 60 birds per replicate. All the chicks were fed the same basal diet (0.04 mg∙kg(-1) Se) for 56 d. The Se concentrations in serum and tissues (liver, kidney, and breast muscle) of the 56-d-old offspring were significantly (P < 0.01) increased by maternal Se-Met intake compared with maternal SS intake. The antioxidant status of the 56-d-old offspring was greatly improved by maternal Se-Met supplementation in contrast with maternal SS supplementation, which was shown by increased glutathione peroxidase activity in serum and breast muscle (P < 0.01), glutathione concentration in serum (P < 0.05), and total antioxidant capability in pancreas (P < 0.01), as well as cytosolic glutathione peroxidase mRNA abundance in breast muscle, liver (P < 0.01), and pancreas (P < 0.05). The maternal Se-Met treatment was more effective in maintaining the shape of liver and pancreas cells, cell nuclei, chromatin, as well as cell membrane structure, and more organelles were observed in liver cells. The maternal Se-Met treatment had significant (P < 0.05) reduced the 48-h drip loss of 56-d-old offspring in comparison with maternal SS treatment. The results suggest that maternal Se-Met diet is superior to maternal SS diet in increasing Se retention and improving antioxidant status and meat quality of 56-d-old offspring.

    ABSTRACT: An 8-wk experiment using 180 Lingnan Yellow broiler breeders was conducted to investigate the effect of different sources of Se on the concentration and gene expression of selenoprotein P (SEPP1) in broiler breeders and their offspring. After receiving a low-Se basal diet for 8 wk, broiler breeders were randomly allocated to 3 treatments (6 replicates per treatment) and fed corn-soy-based diets supplemented with 0.15 mg/kg of Se from sodium selenite (SS), Se-enriched yeast (SY), and selenomethionine (SM), respectively. Fertile eggs from different replicates were collected during the last week of the experiment and then incubated in different incubator trays in the same incubator. The concentrations and mRNA levels of SEPP1 were determined in liver and kidney of broiler breeders and their offspring, as well as the serum SEPP1 concentration. Compared with SS, both SY and SM significantly increased (P < 0.05) the concentration and mRNA level of SEPP1 in 1-d-old chicks. In broiler breeders, the serum and liver SEPP1 concentrations were notably increased by the use of organic Se (P < 0.05), whereas no differences were found in the kidney. Moreover, the SEPP1 mRNA level in the liver was remarkably elevated (P < 0.05) in organic Se treatments, but also no differences were observed in the kidney. Results of this study indicate that the use of organic Se (SY or SM) in maternal diets is very effective for increasing the concentration and mRNA level of SEPP1, especially in their offspring. No differences between SY and SM were observed.

    ABSTRACT: In total, 180 Lingnan Yellow broiler breeders were used to investigate the effect of different sources of selenium (Se) on the expression of cellular glutathione peroxidase (GPx1) and cytoplasmic thioredoxin reductase (TrxR1) in the liver and kidney of broiler breeders and their offspring by quantitative real-time PCR. There were 6 replicates of 3 dietary treatments. Broiler breeders were fed corn-soy-based diets supplemented with 0.15 mg/kg of Se from sodium selenite, Se-enriched yeast (SY), or selenomethionine (SM). At the end of the feeding trial, liver and kidney mRNA levels of GPx1 and TrxR1 were determined by quantitative real-time PCR, as well as the activity of GPx1 and TrxR1 in liver and kidney of breeders and their offspring. The results showed that, compared with sodium selenite, SY or SM significantly increased (P < 0.05) the activity of TrxR1 in the liver and kidney of broiler breeders and their offspring but not the GPx1 activity. The liver GPx1 and TrxR1 mRNA levels in SY or SM groups were higher (P < 0.05) than that in the sodium selenite group. And the kidney TrxR1 mRNA levels were also significantly increased (P < 0.05) by using SY or SM, whereas there was no significant difference in the kidney GPx1 mRNA levels between the organic or inorganic sources of Se used.
