Abstract
Mycotoxins reduce animal productivity and animal health. The influence of Fusarium mycotoxins in corn co-products on pig performance is an important issue in swine feed industry. This study was conducted to determine the effects of naturally produced Fusarium mycotoxins in Corn Gluten Meal (CGM) on growth performance of nursery pigs. A total 96 weaning pigs comprising 48 gilts and 48 barrows with an initial body weight of 5.08 kg (SD = 1.28) were grouped into 3 blocks in each sex by initial body weight and randomly allotted to 4 treatments in a randomized complete block design. There were 6 replicate pens per treatment and 4 pigs were housed in each pen. The 4 experimental diets mainly based on corn, CGM, dried whey and soybean meal were formulated to contain 4 concentrations of mycotoxins derived from the contaminated CGM. Diet 1 contained 32 µg kg-1 Deoxynivalenol (DON) and 6 µg kg-1 Zearalenone (ZON) and diets 2, 3 and 4 contained 532, 1,033 and 1,534 µg kg-1 DON and 203, 399 and 596 µg kg-1 ZON, respectively. During the first 14 d of experiment, Average Daily Gain (ADG) was reduced linearly and quadratically (p

The current study showed that dietary Fusarium mycotoxins derived from contaminated CGM by Fusarium fungi resulted in decreased growth performance of nursery pigs
Summary
There are a number of studies that have shown the harmful effects of DON 1997; Waché et al, 2009) and ZON (Young et al, 1981; Wang et al, 2012) on growth performance of pigs. There is limited information on the effects of DON and ZON in corn co-products contaminated by Fusarium fungi. The aim of this study was to determine detrimental effects of dietary Fusarium mycotoxins naturally contaminated in Corn Gluten Meal (CGM) on nursery pigs
