Abstract
The link between mycotoxin contamination of roughage and the growth and occurrence of diseases were investigated in 34 Japanese Black cattle breeding farms. Contamination with aflatoxin (AF) B1 was detected in five of 22 corn silage and two of 11 wrapped grass silage, respectively, resulting in the contamination of maternal milk with AFM1. Contamination with deoxynivalenol was also detectable in one of 22 corn silage. A decrease in the daily gain of calves, increase in calf diarrhea and premature birth were found on farms fed highly contaminated silage. The level of serum AST was elevated and the number of MHC II+ CD14+ -monocyte was reduced in calves with diarrhea. These results suggest that the mycotoxin of roughage may be related to a depression of the growth and occurrence of diseases of calves via a suppressed immune response.
