预防猪只霉菌毒素中毒

霉菌毒素(Mycotoxin)是某些丝状霉菌在适宜温、湿度条件下产生的次级代谢产物。现已查明的霉菌毒素有300多种,主要污染粮油食品和动物饲料。当前霉菌毒素污染问题在饲料原材料、青贮饲料和成品饲料中变得更加普遍(霉菌毒素当前在80%以上的农产品中都存在)。所有的农作物在生长、采后贮藏以及加工时期,都可能会被产毒霉菌产生的霉菌毒素污染。

霉菌毒素的经济影响

霉菌毒素是一个世界性的重大问题,给众多国家造成了巨大的直接或间接经济损失。让料仓中谷物的温度和水分含量保持在较低的水平并定期通风,可以防止霉菌毒素(如赭曲霉毒素和黄曲霉毒素)的蓄积。

Various Impacts of Mycotoxins on Turkey Health and Performance

The objective of the trial was to show the negative impact of contamination with deoxynivalenol(DON,vomitoxin)in turkey poults feed and the ability of three mycotoxin deactivators to minimise DON effects in vivo.1596 one-day-old Hybrid tom turkeys were randomly placed into 38 floor pens(42 poults/pen).Each pen was assigned to 1 of 5 treatments in a randomized complete block design with each pen blocked by room and location within a room.Basal feed was prepared using uncontaminated or naturally contaminated maize.The treatments were then added to a standard turkey starter diet.Control group was fed uncontaminated diet.DON group was fed diet contaminated with 9,120μg/kg DON.Third group was fed diet contaminated with 9,120μg/kg DON and treated with UNIKE?Plus.Fourth group was fed diet contaminated with 9,120μg/kg DON and treated with Product A and the last group was fed diet contaminated with 9,120μg/kg DON and treated with Product B.The turkeys fed the UNIKE?PLUS treatment consumed more feed compared to those that were fed the DON contaminated diet(P<0.05).However,the feed consumption of birds fed Products A or B was not different from the DON treatment(P>0.10).With higher average daily feed intake,birds assigned to the UNIKE?PLUS treatment had a higher average daily gain and a higher final body weight compared to the DON treatment(P<0.10).The rate of average daily gain and body weight of turkeys fed the other 2 additives(Products A or B)were not different from the DON diet.There were no statistically significant differences in feed efficiency between treatments.This experiment demonstrated the negative influence that DON(and possibly other trichothecenes)has on feed consumption and the subsequent impact this has on the FCR and growth in young turkey poults.The mycotoxin deactivator UNIKE?PLUS reduced these negative effects and clearly performed better than the other two common brands of mycotoxin deactivators.

霉菌毒素--困扰家禽营养的永恒话题

霉菌毒素是由真菌在代谢过程中自然产生的有每物质。它可在农作物仍在大田中尚未收获前侵入种子,或者霉菌于谷物在饲料厂或农场贮存期间产生并生长。因此,农作物在进入饲料厂或农场之前已经含有大量的霉菌毒素（图1）。霉菌在饲料加工过程中也能生长,尤其是在混合过程中饲料的温度和湿度都提高时。最后,如若农场的粮仓、运输系统和饲养人员使用不当,霉菌也可能生长并产生霉菌毒素。

霉菌毒素概况2--霉菌毒素：2016何去何从

2015年6月末和7月初,欧洲的热浪打破了月记录,甚至是一些历史记录。天气是决定是否会引发谷物遭受黄曲霉毒素污染问题的最重要因素。炎热干燥的天气会增加由曲霉属真菌产生的黄曲霉毒素数量。7月6日,（西班牙）马德里创造了该月新的高温纪录,最高气温达39.9℃（103.8℉）,超过1995年7月24日（39.5℃）以来的高温记录。德国的历史高温记录被7月5日的基钦根县高温推翻,最高气温达40.3℃（104.5℉）。
