霉菌毒素对动物的危害2007-201307课稿.ppt

Newborn pigs with swollen vulva – ZEA can be transferred through placenta; affects young animals health, survival and longevity. Another risk of sow and cow in reproduction. * Key point here is that the digestibility is in progressive mode, that means it takes a week to show the accumulative effects. When we compare at d-18; you can see 6 % difference for all levels of ZEA even though average of protein digestibility was different between 1, 2, 3 ppm ZEA. If you go back to previous slide, we see 2% decrease on CP on average basis; but at the end of feeding 18-d, it was actually 6% reduction. * GPX and TSD are good enzymes inside the cells; they protect cells from free radicals, peroxide etc. damage. Higher number is better. * We see higher challenge 2 and 3 ppm of ZEA reduced antibody titer but not in pigs fed 1 ppm. We believe longer time feeding with low ZEA concentration will show similar results. * IgG is important for antibody production. * * * Fusarium 綜合毒素對豬隻的影響 平均日增重, g 平均每日取食量, g 增重 : 取食量 飼料不含毒素 428a 778a 0.558a 含毒素飼料 280b 524b 0.533a 共有 175 乳豬 (平均體重 10 kg) 試驗 21 天 含毒素飼料含有 DON 5.5 ppm, ZEA 400 ppb, FUA 26.8 ppm Swamy et al., J Anim.
