增强肉鸡免疫力的饲料营养技术

发布日期:2019-11-25 16:36 来源:http://scsqtx.com 点击:

由于我国肉鸡饲养采用千家万户“小规模,大群体”的发展模式,存在鸡舍选址不合理,设施简单,建筑工艺落后,环境条件控制差、废弃物处理差等不利因素,导致肉鸡多处于亚健康状况下,南阳柴鸡苗北京11选5肉鸡免疫力低,容易因饲料污染或霉变、环境突然变化或外界病原微生物感染呈现免疫应激反应,导致死亡率升高。因而,在目前状况下,通过饲料营养或添加剂途径提高肉鸡的免疫能力,提高其抵抗免疫应激能力是当前乃至未来我国肉鸡饲料配制技术中的需要重点考虑的问题。

应激状况下,肉鸡为了抵抗应激,合成应激蛋白增强。但由于肉鸡采食量下降,供给南阳柴鸡苗蛋白质合成的氨基酸受限,蛋白质分解代谢明显高于合成代谢,营养状况恶化,呈负氮平衡。同时,免疫应激抑制脂肪合成、促进脂肪和碳水化合物分解供能;微量元素中更多的铜用于合成血浆铜蓝蛋白,提高血清铜含量,而血浆铁、锌含量下降。因而,由于组织大量消耗能量,改变了营养素的分配和代谢,使得机体对维生素和氨基酸等营养素的需求量急剧增加。如果各种营养素得不到满足,机体很快进入衰竭状态。
