Effects of Dietary Vitamin D Forms on Reproductive Performance of Boars
摘要
Abstract
This study was conducted to investigate the effects of dietary vitamin D supplementation forms on re-productive performance of boars.Sixteen Yorkshire boars with eighteen months of age were randomly allocated to one of two groups, dietary contents of vitamin D3(VD3) and 25-hydroxycholecalciferol (25-OHD3) were both 50 μg/kg in different groups, respectively.Each group had 8 replicates with 1 boar per replicate.The trial lasted for 16 weeks.The results showed that compared with VD3 group:sperm motility, effective sperm num-ber per ejaculation in 25-OHD3 group were significantly increased in 1 to 16 weeks ( P<0.05) , while deformi-ty ratio was significantly decreased ( P<0.05);plasma calcium ion ( Ca2+) content, estradiol content and aro-matase activity in 25-OHD3 group were significantly increased at day 112 ( P<0.05) , and seminal plasma 25-OHD3 content, Ca2+content, fructose content and acid phosphatase activity in 25-OHD3 group were significant-ly increased ( P<0.05);the expression levels of aromatase, vitamin D 25-hydroxylase,vitamin D 24-hydroxy-lase and vitamin D receptor genes in 25-OHD3 group were significantly increased (P<0.05).In conclusion, compared with the same level of VD3 , supplementation of 25-OHD3 in diet is conducive to increase plasma vi-tamin D content, so as to improve sperm morphology and athletic ability, and then improve reproductive per-formance of boars.关键词
