飼料霉變不但造成飼料廠損失巨大，而且飼料營養(yǎng)物質(zhì)被分解，適口性下降，并產(chǎn)生許多霉菌毒素，造成
長毛兔的生長速度減慢，采食量下降，消化率降低。下面詳細來講講給兔子飼喂霉變飼料的危害。
Feed mildew not only causes great losses to feed plants, but also decomposes feed nutrients, reduces palatability, and produces many mycotoxins, which slows down the growth rate of long haired rabbits, reduces food intake, and reduces digestibility. The following is a detailed description of the harm of feeding rabbits moldy feed.
1、降低飼料營養(yǎng)價值
1. Reduce the nutritional value of feed
霉菌能利用飼料中的營養(yǎng)成分生長繁殖，從而降低飼料的營養(yǎng)價值。
Molds can use the nutrients in the feed to grow and reproduce, thus reducing the nutritional value of the feed.
2、影響家兔繁殖性能
2. Affecting the reproductive performance of rabbits
鐮刀菌屬霉菌所產(chǎn)生的脫氧雪腐鐮刀醇（DON）和玉米赤霉烯酮（ZEA）及黃曲霉菌產(chǎn)生的黃曲霉毒素，能導致動物產(chǎn)生陰囊紅腫、子宮擴張腫脹及卵巢萎縮等癥狀，使母兔發(fā)情周期延長，繁殖率下降；公兔**萎縮等。
Deoxynivalenol (Don) and zearalenone (Zea) produced by Fusarium molds and aflatoxin produced by Aspergillus flavus can cause animals to develop symptoms such as scrotum swelling, uterine expansion and ovarian atrophy, prolong the estrous cycle of female rabbits and reduce the reproductive rate; Male rabbits * * atrophy, etc.
3、干擾家兔免疫系統(tǒng)
3. Interfere with rabbit immune system
飼料中黃曲霉毒素會影響家兔免疫器官發(fā)育，干擾免疫接種與體內(nèi)獲得性免疫力，從而降低家兔的抗病力。單端孢霉素類（T-2毒素、DON等）是免疫抑制劑，能降低機體的免疫應(yīng)答能力。飼料中黃曲霉毒素含量較低時，即使不導致明顯的臨床癥狀和生產(chǎn)性能下降，也會使家禽的免疫功能下降，對病原感染的敏感性升高。
Aflatoxin in the feed will affect the development of immune organs of rabbits, interfere with immunization and acquired immunity in vivo, and thus reduce the disease resistance of rabbits. Monosporidins (T-2 toxin, don, etc.) are immunosuppressants, which can reduce the immune response ability of the body. When the content of aflatoxin in the feed is low, even if it does not cause obvious clinical symptoms and production performance decline, the immune function of poultry will decline and the sensitivity to pathogenic infection will increase.
4、影響家兔生長發(fā)育
4. Affecting the growth and development of rabbits
黃曲霉毒素可與飼料中的物質(zhì)反應(yīng)，生成物可致飼料品質(zhì)惡化，適口性降低，導致家兔的釆食量和體增重下降；能干擾體內(nèi)蛋白質(zhì)、碳水化合物和脂類的代謝，降低家兔生長速度。霉菌毒素還能侵害動物肝臟及腎臟，影響家兔生長發(fā)育。
Aflatoxin can react with the substances in the feed, and the products can cause the feed quality to deteriorate and the palatability to decrease, resulting in the decrease of feed intake and body weight gain of rabbits; It can interfere with the metabolism of protein, carbohydrate and lipid in vivo and reduce the growth speed of rabbits. Mycotoxins can also damage the liver and kidney of animals and affect the growth and development of rabbits.
實際上飼料霉變的原因很多，靠單純使用某種防霉劑來達到防霉效果是不可能的，須采取綜合防治措施，控制水分，減少霉菌污染，合理添加防霉劑，縮短從生產(chǎn)到用戶的時間等，才能從根本上解決飼料霉變問題。所以在飼養(yǎng)兔子的時候要多方面來考慮問題，不要隨意選擇飼料。更多相關(guān)內(nèi)容就來我們網(wǎng)站

In fact, there are many reasons for feed mildew, and it is impossible to achieve the effect of mold prevention by simply using a certain mold inhibitor. Comprehensive prevention and control measures must be taken to control water, reduce mold pollution, add mold inhibitor reasonably, and shorten the time from production to users, so as to fundamentally solve the problem of feed mildew. Therefore, when raising rabbits, we should consider many aspects and do not choose feed at will. For more information, please visit our website http://m.114gov.cn Let's see.
