脱霉剂对保育猪病亡率及粪便中霉菌毒素含量影响

本试验旨在探究日粮中添加不同脱霉剂产品对保育猪病亡率及粪便中霉菌毒素含量的影响,将419头饲养密度、体重相近的长白×大白二元保育猪随机分为7组,每组62头,每组设3个重复小组,每个重复小组约20头。各组安排如下：试验1组为饲喂正常基础日粮对照组（58头）;试验2组为基础日粮＋0.5kg/t缉毒特工（60头）;试验3组为基础日粮＋0.5kg/t市售脱霉剂（63头）;试验4组为基础日粮＋1kg/t缉毒特工（59头）;试验5组为基础日粮＋1kg/t市售脱霉剂（61头）;试验6组为基础日粮＋2kg/t缉毒特工（61头）;试验7组为基础日粮＋2kg/t市售脱霉剂（57头）,试验期45天。结果表明：1）各添加脱霉剂组的腹泻率,阴户红肿率以及死亡率显著优于空白对照组（P〈0.01）,同剂量组间比较,缉毒特工组的病亡率低于市售脱霉剂组,且试验6组的病亡率均优于对照组和其它各试验组（P〈0.01）。2）试验期添加脱霉剂的各试验组粪便中ZEN（玉米赤霉烯酮）和DON（脱氧雪腐镰刀菌烯醇）的排出量显著多于对照组（P〈0.01）,且随脱霉剂添加剂量增加,ZEN和DON排出量呈增加趋势。同剂量组间,添加缉毒特工组的排出量显著多于添加市售脱霉剂组。因此添加霉菌毒素复合处理剂缉毒特工可有效处理猪体内霉菌毒素,改善病亡状况,同时对其免疫力也起一定的积极作用。

Effects of Mycotoxin Adsorbent on Mortality and Morbidity and Mycotoxin of Feces in Weaner Piglets

This experiment was conducted to study the effects of mycotoxin adsorbent on mortality and morbidity and mycotoxin of feces in weaner piglets. The 419 stocking density,similar weigh （Landrace × Large White） weaned piglets with an average initial weight were divided into seven groups（62 pigs per group）,each set three repeat groups （about 20 pigs each repeating group）. The 7 groups were as follows： group 1 is control group （a basal diet,58pigs）. Group 2,4,6 were fed diets containing 0.5kg/t,1kg/t,2kg/t of JDTG separately. Group 3,5,7 were fed diets containing 0.5kg/t,1kg/t,2kg/t of Mycotoxin adsorption in the market （MAM for short） separately. The experimental period lasted for 45d. The results showed as follows： 1） compared with the control group,diarrhea, swelling of the vulva and the mortality rate in the supplement of mycotoxin adsorbent in diets was significantly decreased （P0.01）. Compared with the same dose groups,JDTG groups set off mortality and morbidity is lower than MAM groups. Especially,mortality and morbidity of 6 groups is lower than the control group and the other experimental groups （P0.01）. 2） The ZEN and DON of feces in the groups included the mycotoxin adsorbent（basal diet） was significantly higher than the control group （P0.01）. The number of ZEN and DON of feces increases with the increase of the mycotoxin adsorbent increase. Compared with the same dose groups,adding JDTG in diets were significantly more than adding MAM in diets. So adding mycotoxin complex treatment agent（JDTG） can effectively control mycotoxins,diminish the mortality and morbidity,and play a positive role in their immunity.
