农民信息网 www.fxnonstop.com 农民朋友如何喂养大河乌猪种母猪?它是中外混血猪品种,继承了多重父母代优势,全国各地都可以饲养,它就是产自云南的一个优良的猪种,大河乌猪。在我国养猪行业,通过外来猪和本地猪杂交选育来改良地方良种的生长性状,从而提高猪的生产性能,是我国猪种繁育的经常做法了,大河乌猪就是这样一个杂交品种。它是由杜洛克猪云南本地猪杂交改良而成,保留了百分之五十原种的基础,经过多代选育的优质猪种。大河乌猪肉质优良,瘦肉率高,受到消费者追捧,在农民信息网新玩家汇娱乐养殖市场前景看好,农民朋友们如何养殖大河乌猪?大河乌猪母猪的喂养、管理环节要注意的事项等等,就这些问题,笔者下面就来讲一讲关于这猪种的养殖技术。

大河乌猪的喂养可以采用湿拌料喂猪,湿拌料掺水比例为1比1,不可拌成粥料。喂料实行“三定”即定时、定质、定量,即每天固定喂食时间和次数(小猪5次,大猪4次),每天喂料品质一般固定不变,每天限喂食数量(每次喂八九分饱)。食后自由饮水可以提高饲料利用率。在青饲料原料上,养殖户可以进行种草养殖,主要是在上年的秋末冬初或当年春季,种植hn-mc优优菊苣、hn-mc优优籽粒苋等多汁叶菜类牧草。然后在夏秋季节收获鲜草喂猪利用,这类牧草可以占到猪日粮的10%~30%,育肥猪在育肥期内,每头猪大约可以消耗牧草(干物质)约80kg;在牧草正常生长条件下,每100头猪需要种植6~12亩多汁类牧草。

对于母猪的牧草供给:母猪的牧草供给数量主要考虑到母猪的不同生理阶段。

空怀阶段:每天喂0.5~1kg精料,8~10kg鲜草或20%~30%的玉米+10%麸皮与60%~70%牧草干草粉混合饲喂;母猪过瘦时,应补充较多的精料。

妊娠前80天:此时对饲料中的各种营养成分有较高的利用率,加之胚胎生长发育缓慢,是节省精料的最佳时期,每天可以饲喂精料0.5~1kg,优质牧草的鲜草8~10kg。

妊娠80天后的母猪:妊娠后期的母猪,即至产仔时间大约还有35天时,母猪的饲料应适当增加能量和蛋白质,补充钙,每日在饲料中加20g骨粉或50g鱼粉。将精料由0.5~1kg/天提高到1~1.5kg/天,把优质牧草调整至5~6kg/天。

母猪哺乳阶段:哺乳母猪应增加精料的饲喂量,并适当补钙,精料喂量为2.5~3kg/天,搭配饲喂8~10kg的鲜草。哺乳母猪的精饲料可以按如下搭配,60%玉米+30%麸皮+10%母猪浓缩饲料;或用50%玉米+30%麸皮+18%豆饼+2%骨粉。牧草的饲喂供给量,根据母猪的采食量来确定,一般可以3~4kg/天。

在大河乌猪的养殖中,农户大都忽视“防重于治”的原则,注重对猪的治疗,宁愿在治疗上花“大”钱,不愿在防疫上花“小”钱,结果是农户损失惨重。因此,夏秋季猪舍要注意通风换气,可在猪舍内安装电扇,降湿防暑。猪舍外栽植藤蔓类植物遮阳降温,保持猪舍内空气新鲜和温度适宜。冬季推广塑料薄膜暖棚养殖新技术,不断改善猪舍小气候,给猪生长发育创造一个良好的生态环境。同时还要坚持严格的消毒制度,经常打扫环境卫生。有条件的猪舍安装纱网防止蚊蝇的叮咬,减少疫病的发生和传播。定期搞好驱虫和疫病免疫注射,推行“防重于治”的原则。
