有机锌

有机锌的大作用

有机锌是合成固醇类激素如性激素所必需的微量元素,因此锌在生殖方面起着独一无二的重要角色,锌的缺乏或过量都会对动物的繁殖性能产生不利的影响。如果缺锌会影响到母猪的整个繁殖过程。母猪长期采食锌量不足的饲料,会引起卵巢发育不良、萎缩、流产甚至难产和早期胚胎容易死亡。邹晓庭等报道,日粮中适量增加妊娠母猪日粮锌的含量,可提高新生仔猪血清白蛋白水平和母猪血清孕酮含量,降低血清中尿素氮含量。在妊娠母猪饲料添加适量的锌,断奶至发情间隔缩短,母猪的产仔能力显著的提升(P<0.05),断奶后再发情率和受胎率提高;后备母猪初次发情时间提前;初情期体质量明显增加,产仔性能显注提高(P<0.05)。
