| description | ABSTRACT The objective of this study was to analyse the impact of dietary vitamin E supplementation on laying performance, serum reproductive hormones concentration and gene expression in ovary and follicles of anti-season breeding goose. A total of 210 anti-season breeding geese were divided into seven treatments with six replications. Each group was supplied with diets containing different vitamin E (DL-α-tocopherol acetate) contents (0, 10, 20, 40, 80, 160, 320mg/kg). We observed that the egg production and laying rate improved significantly at doses of 10 and 80 mg/kg, while the highest egg weight appeared in the 320 mg/kg group. Meantime, 80 mg/kg of vitamin E supplementation significantly improved the concentration of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in serum (p<0.05). Dietary vitamin E supplementation significantly enhanced mRNA expression of FSHR, LHR and ESR1 at a dose of 80mg/kg, while PRLR increased at doses of 10 and 20mg/kg (p<0.05). It was found that the mRNA expression of Dicer increased at doses of 40 and 80 mg/kg of vitamin E supplementation in the ovary, SWF, LWF and SYF, respectively. Thence, Dietary vitamin E supplementation could improve egg laying performance, plasma reproductive hormones and the mRNA expression of reproductive hormone receptor genes in ovary, as well as the mRNA expression of Dicer in ovary, SWF, LWF and SYF. It was supposed that 80 mg/kg of vitamin E supplementation in dietary was appropriate to improve the fertility of anti-season breeding Xingguo grey goose. |
