class=""><P align=center>　　縣畜牧獸醫(yī)局劉書生</P> <P>　　近年來,許多養(yǎng)豬場或養(yǎng)殖戶,常出現(xiàn)母豬發(fā)情推遲或?qū)遗洳辉械痊F(xiàn)象均有發(fā)生，致使養(yǎng)豬場經(jīng)濟效益得不到有效提高。<BR>　　一、原因<BR>　　1、環(huán)境因素。<BR>　　①種公豬、種母豬、豬舍建設(shè)不科學，光照不足或很差，易影響母豬發(fā)情推遲或準胎率下降。<BR>　?、谔鞖庋谉幔募咎鞖庋谉?，致使母豬發(fā)情率比其它季節(jié)要低20%，初產(chǎn)母豬更為明顯。<BR>　?、厶鞖夂洌率鼓肛i發(fā)情率低。<BR>　　2、飼養(yǎng)管理因素。<BR>　?、倌肛i營養(yǎng)狀況不良，仔豬斷奶后，母豬偏瘦、過肥都有屢配不上更為明顯，如果臨產(chǎn)前母豬體重為170Kg左右，仔豬斷奶時母豬體重減輕至11Kg左右，則有20%的母豬4-5天發(fā)情，20%的母豬7-10天發(fā)情，60%母豬不發(fā)情或發(fā)情不明顯，特別二元雜交作母本，約榮雜交、長大雜交，飼養(yǎng)戶有時叫苦連天，飼養(yǎng)母豬一年多見不了利，飼養(yǎng)母豬虧本，仔豬斷奶后，母豬體重為170Kg，減少140kg左右，80%的母豬4-5天發(fā)情，發(fā)情持續(xù)期延長1-3天，20%的母豬7-10天發(fā)情，從以上重量情況可以看出，母豬的營養(yǎng)狀況對仔豬斷奶后母豬的發(fā)情時間有較大影響。<BR>　　②母豬營養(yǎng)過剩，過于肥胖，由于食欲旺盛，母豬體重增加過快，再加飼喂不限量，飽食飽飲，一吃就一桶食，易導(dǎo)致母豬過肥，母豬卵巢及其它生殖器官被脂肪包埋，子宮輸卵不通，造成母豬排卵減少或不排卵，出現(xiàn)母豬屢配不孕，甚至不發(fā)情等現(xiàn)象。<BR>　?、酆髠淠肛i機體尚未發(fā)育成熟。體成熟不等于性成熟。后備母豬機體尚未發(fā)育成熟,體成熟不等于性成熟。后備母豬年齡偏小，尤其是品種母豬雖然外觀、體格已尼成熟，但月齡較小，生殖器尚未發(fā)育成熟，母豬40kg-50kg，沒有發(fā)情，飼養(yǎng)員就著急，心想早配種早收益。<BR>　　④種公豬精液量少、質(zhì)量并、死精，由于營養(yǎng)不足種公豬運動少多方原因，疫病、天氣炎熱、寒冷等原因，都可引起種公豬的精液稀釋液配方，不按配方量，不用天平，用勺子估量，騎著摩托車好路、壞路不顧，顛簸對精液振動大、有影響，保持溫度，授精不負責任，熱不管，冷不管，沒有講究技術(shù)操作要領(lǐng)，有的將精液瓶放著自己衣袋內(nèi)，不加溫，抽到輸液管就用，偷懶省事。有得只想著錢上，忘了服務(wù)質(zhì)量，飼養(yǎng)戶打個電話，說自家母豬發(fā)情時，第二天去了，是不是時宜配種時間，先輸一管，不行下次再來。對授精跑路也不合算，飼養(yǎng)母豬18-20飼料、人工、時間的浪費。<BR>　?、萁H繁殖，亂交、亂配或近親交配。<BR>　?、夼浞N不適時，過早或過晚。發(fā)情不等于母豬排卵，母豬發(fā)情24小時，36小時內(nèi)配最適宜，做到重復(fù)配，間隔8-12小時再配一次，按照母豬齡來定，正確掌握母豬發(fā)情期和排卵時間，做適時配種，老配早、小配晚，不老不少配中間的原則，進行適時配種。配種最好時機母豬發(fā)情眼淚掛腮，正好受胎，在背腰部按壓不動正好配種。<BR>　?、咭卟∫蛩?，先天性疫病，非傳染性疫病，傳染性疫病等均可導(dǎo)致母豬屢配不孕或不發(fā)情。<BR>　　⑧母豬年齡過大，生殖機能退化，致使不孕，生產(chǎn)母豬年齡必須5-7年，超過年齡必須淘汰、更新。<BR>　　二、防治<BR>　　1、預(yù)防。選好種公豬、種母豬，有先天缺陷的不得留作種用，要淘汰老齡母豬，培養(yǎng)青年母豬，加強種公豬、種母豬的飼養(yǎng)管理。<BR>　　2、治療。<BR>　?、偃斯ご咔?。公豬誘導(dǎo)催情，又叫異性催情，隔離仔豬催情，按摩母豬乳房催情，換欄催情，又叫遷移催情，合群催情將后備母豬每欄飼養(yǎng)10-30頭，斷奶后的母豬每欄飼養(yǎng)6-8頭，運動催情，加強母豬運動，進行放牧放青，促進發(fā)情。<BR>　?、谒幬锎咔?。注射三合激素，催情針，孕馬血清注射液5ml，中藥種玉子散，當歸，川芎，熟地，肉杜，陳皮，丹皮，英芋，妙葉，一把，條苓，香附子，桃仁，紅花。</P></div><div
