港北区“微生物+”养殖效益叠加

2017-08-23 09:27:18   中国青年网

本报南宁讯(记者/袁琳)“‘微生物+’养殖效益真是让人出乎意料!”近日,贵港市港北区的福林龙宝生态养殖有限公司公司负责人把账算了一算后,欣喜地向记者说。

这笔账是这么算的:猪舍全部使用高架网床,相对传统猪舍减少70%用水量;通过在饲料中添加微生物,发酵饲料、改善肠道、分解粪便,大幅减少抗生素用量,粪便无臭,使全程料肉比相比传统养殖减少0.1个百分点,仅此项养殖成本就降低60-70元,实现产量质量双双提升;同时,引进使用有机肥生产设备,把猪粪全部转变成有机肥,结合种植200亩果蔬,实现生猪饲养“零排放+果蔬种植”的转型升级。

据悉,近年来,港北区全面推广以“微生物+”为核心的现代生态养殖模式,实施畜禽规模养殖场生态化改造工程,不断提升养殖科技含量,使养殖模式逐渐由传统散养向规模化、标准化、生态化的养殖模式转变,有效解决传统养殖的污染问题,打造出生态循环绿色产业。

该区西江奶牛场推广应用的是“微生物+发酵床”的模式。记者看到,该场利用甘蔗发梢、稻草、木薯渣、象草、燕麦草等秸秆资源,添加微生物发酵,作为奶牛的基础食粮,利用稻壳、花生壳、牛粪渣等废弃物,喷洒微生物作为发酵床的垫料。通过这些措施,不但养殖成本可降低15%-20%,而且进一步提高了饲料适口性,提高奶牛的采食量,改善肠道环境,减少奶牛疾病特别是乳房炎的发生,提高了牛奶产量和质量,奶牛一个泌乳期产量增加2-5吨。

为扩大“微生物+”养殖规模,该区重点推广高架网床,把传统栏舍、平养猪舍改造成半漏缝或发酵床,把传统的自动饮水装置改为防漏水装置,实现饮水分离和粪尿分离。
