有機鋅的大作用

有機鋅安徽快3是合成固醇類激素如性激素所必需的微量元素,因此鋅在生殖方面起著獨一無二的重要角色,鋅的缺乏或過量都會對動物的繁殖性能產生不利的影響。如果缺鋅會影響到母豬的整個繁殖過程。母豬長期采食鋅量不足的飼料,會引起卵巢發育不良、萎縮、流產甚至難產和早期胚胎容易死亡。鄒曉庭等報道,日糧中適量增加妊娠母豬日糧鋅的含量,可提高新生仔豬血清白蛋白水平和母豬血清孕酮含量,降低血清中尿素氮含量。在妊娠母豬飼料添加適量的鋅,斷奶至發情間隔縮短,母豬的產仔能力顯著的提升(P<0.05),斷奶后再發情率和受胎率提高;后備母豬初次發情時間提前;初情期體質量明顯增加,產仔性能顯注提高(P<0.05)。
