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. Reduce the nutritional value of feed
Molds can use the nutrients in the feed to grow and reproduce, thus reducing the nutritional value of the feed.
2. Affecting the reproductive performance of rabbits
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. Interfere with rabbit immune system
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. Affecting the growth and development of rabbits
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.
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.
