 跟着季候更迭,气候逐步转冷,局部地域气温降落10以上。为降落气候变更对生猪出产形成的影响,受农业乡村部畜牧兽医局拜托,国度生猪财产技术系统专家组提出以下五项技术办法,供泛博养殖场户参考。 

  一、做好非洲猪瘟等关键疾病的防控 

  FEIZHOUZHUWENBINGDUXILENGPARE、XICHAOPAGAN,QIWENTURANJIANGLUOWEIFEIZHOUZHUWENBINGDUDECHUANBUDIZAOLEYOUYIQIANTI。WEIZUOHAOFEIZHOUZHUWENDENGYIBINGDEFANGKONG,ZHUCHANGYINGWANMEISHENGWUNINGJINGXITONG,ZIFAFENGCHANG,XUEJIANDUIWAIJIAOHUAN,YOUYONGZHIZHIYIQINGCHUANRUHEFENSAN。 

  起首,加强很是猪只的监控。但凡表现为: 体温下降、腹泻/血痢、吐逆、流涎、减料/厌食、体表发红、口鼻流血、流血不止、腹部等部位有出血斑,呈现神经病症等,均应停止采样。样品收罗以后必须尽快冷藏或冷冻,并实时送检。

  第三,做好罕见多病发的防控。斟酌到气温突然降落,高温高湿情况易引发多种罕见多病发,包含: 猪呼吸道疾病(支原体肺炎、肋膜肺炎等)、胃肠道疾病(大肠杆菌病、沾染性胃肠炎、风行性腹泻等)及各类皮肤病(霉菌病、疥螨、葡萄球菌病等)。呼吸道疾病的节制,要从消弭病原、改良猪场情况、加强豢养办理等多方面动手。胃肠道疾病多接纳补液、止泻、避免脱水和酸中毒的体例对症处置,可接纳鞣酸卵白、药用炭或次硝酸铋收敛止泻,停止帮助医治,也可恰当操纵抗生素药物,避免继发沾染。对沾染性胃肠炎、风行性腹泻、猪流感等猪沾抱病的防控,一方面要避免猪舍温度变化过大,抱负状况是节制在2℃/小时之内,并避免贼风侵袭;另外一方面要展开口蹄疫、沾染性胃肠炎、风行性腹泻、猪流感等猪沾抱病免疫和监测任务,做好全进全出办理与空栏消毒。 

  二、做好猪舍御寒保暖 

  保温与透风是气温骤变季候猪场办理的关键。温度是影响生猪发展的首要情况因子。差别日龄猪对温度应激有差别顺应范围,即猪发展发育最适温度,可用下式预算: T=-0.06W26,如: 20公斤仔猪最适温度为T=-0.06×2026=24.8℃T为最适温度;-0.06为最适温度系数;W为猪体重;26为适温度常数),下表列出了差别春秋阶段猪只最适温度范围。养殖场应答气温突然降落,起首要确保猪舍门窗的无缺,避免贼风侵袭;确保供电、供水、保温等举措办法普通,重点做好产房和保育舍仔猪的保温,营建和缓温馨的猪舍吝啬候。南边地域猪舍修建多重视透风降温,顶棚保温较差,为取得好的透风结果,顶棚距离空中较高,倒霉于舍内温度进步。为应答骤变气候,可在舍内猪床的上方用塑料薄膜、防雨布、木板等资料搭建姑且二层棚(普通2米高),并操纵红外线保温灯、保温板、暖风炉等办法,确保产房仔猪取和缓和保育舍温度。

  三、严酷履行科学的消毒法式

  物资消毒。猪场门口及出产区门口要设置单向畅通的物资消毒间,并保障消毒间密闭性杰出。对小型物资可操纵10ppm臭氧熏蒸消毒30min以上;对疫苗等须要高温保管的物资可撤除到最小包装后操纵暖和型消毒剂浸泡或擦拭消毒;对手机、电脑等电子装备和紧密仪器,可先用氯制剂擦拭后,再65℃30min高温消毒。对不能进入消毒间的大型物资可操纵消毒机停止喷洒消毒某人工擦拭消毒。 

  情况消毒。对办公楼、宿舍楼内情况可操纵0.5%过氧乙酸或1000毫克/升含氯制剂喷雾,迟早各一次。办公室、过道、餐厅、通报窗、洗手间等安排免洗消毒液,随时停止手部消毒。对出产区猪舍连廊由出产区专人担任,每3天用2%烧碱喷洒一次;场区通道、过道天天用2%烧碱或戊二醛喷洒一次;舍内值班室、用具天天喷雾消毒一次。

  另外,在猪只发卖关键,必然要做好职员管控,售猪后应周全清算洁净出猪台上及四周可见的无机物资,喷洒泡沫洁净剂笼盖30min,净水冲刷并枯燥,操纵烧碱、氯制剂等消毒剂喷洒消毒。为避免场内职员外出看磅与收猪职员交换致使穿插,最幸亏出猪台装置物理距离。 

  四、恰当调剂日粮配方,做好平常豢养办理 

  一是恰当进步猪养分摄取量。猪只在高温情况前提下,保持须要增添,是以对能量等养分物资的须要增添。可经由进程两种体例增添猪养分摄取量: 调剂饲料配方,过度进步饲料能量程度,如在饲猜中增添10%15%的玉米用量或增添2%3%的动物油,并恰当增添具备抗应激、抗氧化才能的复合维生素、氨基酸、复合酶制剂等;恰当增添饲喂次数,在夏季,昼短夜长,猪群晚间空肚时候长,在夜间增添一次喂料,以增添天天采食量。

  采用温水给猪饮用,水温在20℃以上,能够削减猪只腹泻,削减体温的流失。煤炉连体水槽,供应温水是个不错的体例。煤炉就在水槽中,与水槽联体,水槽的外壁和穿行在水槽中的排烟管都能够加热水槽中的水,岂但煤的操纵效力高,并且加热结果好,值得在我国西南、东南和华北等严寒地域推行。 

  同时,进步日粮能量浓度在气温较低时,饲猜中精料供应量应比日常平凡增添15%,有前提的可采用温热湿板料饲喂,同时进步日粮的能量,倡议极端严寒季候日粮能量要在之前的根本上进步0.10.3大卡的热量,注重日粮的调制增添可口性以进步采食量。补充增添矿物元素和维生素,特别是母猪和仔猪阶段,可在饲猜中恰当进步矿物元素的含量,平均地补充青贮饲料和胡萝卜,以防持久的封锁和阳光的短时间形成维生素缺少,引发皮肤病或滋生妨碍等。 

  五、做好种猪培养,实行自繁自育 

  自繁自养有益于避免带入外来疫源,若是确切须要引种,应事前做好相干疫病检测任务,避免购入病猪和隐性沾染猪。种猪参加后,断绝豢养40-60,按既定法式停止免疫接种,肯定无疫病后,方可混群豢养。
