饲料霉变不但造成饲料厂损失巨大，而且饲料营养物质被分解，适口性下降，并产生许多霉菌毒素，造成长毛兔的生长速度减慢，采食量下降，消化率降低。下面详细来讲讲给兔子饲喂霉变饲料的危害。

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、降低饲料营养价值

1. Reduce the nutritional value of feed

霉菌能利用饲料中的营养成分生长繁殖，从而降低饲料的营养价值。

Molds can use the nutrients in the feed to grow and reproduce, thus reducing the nutritional value of the feed.

2、影响家兔繁殖性能

2. Affecting the reproductive performance of rabbits

镰刀菌属霉菌所产生的脱氧雪腐镰刀醇（DON）和玉米赤霉烯酮（ZEA）及黄曲霉菌产生的黄曲霉毒素，能导致动物产生阴囊红肿、子宫扩张肿胀及卵巢萎缩等症状，使母兔发情周期延长，繁殖率下降；公兔**萎缩等。

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、干扰家兔免疫系统

3. Interfere with rabbit immune system

饲料中黄曲霉毒素会影响家兔免疫器官发育，干扰免疫接种与体内获得性免疫力，从而降低家兔的抗病力。单端孢霉素类（T-2毒素、DON等）是免疫抑制剂，能降低机体的免疫应答能力。饲料中黄曲霉毒素含量较低时，即使不导致明显的临床症状和生产性能下降，也会使家禽的免疫功能下降，对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、影响家兔生长发育

4. Affecting the growth and development of rabbits

黄曲霉毒素可与饲料中的物质反应，生成物可致饲料品质恶化，适口性降低，导致家兔的釆食量和体增重下降；能干扰体内蛋白质、碳水化合物和脂类的代谢，降低家兔生长速度。霉菌毒素还能侵害动物肝脏及肾脏，影响家兔生长发育。

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.

实际上饲料霉变的原因很多，靠单纯使用某种防霉剂来达到防霉效果是不可能的，须采取综合防治措施，控制水分，减少霉菌污染，合理添加防霉剂，缩短从生产到用户的时间等，才能从根本上解决饲料霉变问题。所以在饲养兔子的时候要多方面来考虑问题，不要随意选择饲料。更多相关内容就来我们网站http://www.myxinhua.com看看吧。

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://www.myxinhua.com Let's see.
