Influence of Level of Deoxynivalenol in the Diet of Dairy Cows on Feed Intake, Milk Production, and Its Composition

Abstract: Eighteen primiparous Holstein cows were used in a 10-wk lactation study, preceded by a 2-wk covariate period, to determine the effect of concentration of deoxynivalenol in the diet on cow performance and transfer of deoxynivalenol and its metabolite, deepoxydeoxynivalenol, to milk. Diets were formulated to contain deoxynivalenol at 0, 6, and 12 mg/kg of concentrate DM, and daily intake of deoxynivalenol was .59, 42, and 104 mg, respectively. Increasing deoxynivalenol in the diet did not affect intake of concen… Show more

“…As an example, a decrease in intake and milk production was observed following the administration of 6 to 8 mg DON per kg of concentrate [89,93] whereas no decrease in these two factors was shown after the administration of up to 12 mg DON per kg of concentrate [6,10]. FB1 seems to only have an effect on daily food consumption since the addition of 148 mg of this toxin per kg of feed had no effect on weaned calves [56].…”

“…In mink, feed choice is affected by levels of DON as low as 0.28 mg/kg diet (Gibson et al, 1993). Dairy cows are considerably more tolerant to DON, as exemplified by the lack of effect on feed intake and milk production (Charmley et al, 1993;Ingalls, 1996). However, in Brazil poisoning of cattle fed citrus pulp has been attributed to contamination with DAS which has the potential to cause characteristic clinical symptoms including anorexia, weight loss, haemorrhagic lesions in vital organs and even death (Galhardo et al, 1997).…”

“…AfB 1 reduced cellulose breakdown and production of VFAs and NH 3 both in in vivo and in vitro rumen model systems (Mertens 1977). Charmley et al (1993) observed that 40 g/L fatcorrected milk tended to exhibit a quadratic response to DON concentration in the diet (0, 600 and 1200 mg/kg of DON in concentrate DM). Trenholm et al (1985) recorded a trend towards decreased grain consumption in cows fed a DON-contaminated ration (640 mg/kg in a grain mix).…”
