Megjegyzések:Fusarium toxins in pig feeds: efficacy of mycotoxin adsorbents In two experiments using a total of 220 weaner pigs the hypothesis was tested that apple pomace alleviates the negative effects of Fusarium toxins in pigs. The two experiments had the same two-factor design: Fusarium contaminated vs. uncontaminated wheat, and 8% apple pomace vs. no pomace in the diet. Both trials yielded similar results and were thus evaluated together. The intake of feed that was contaminated with deoxynivalenol and zearalenone reduced feed intake (P < 0.01) and weight gain (P = 0.05) and increased the uterus weight (P < 0.01) without affecting feed conversion ratio. Pomace intake had no effect on feed intake and uterus weight but improved weight gain (P = 0.03; interaction pomace ? mycotoxins: P = 0.08). Apple pomace thus seems to counteract the negative effects of deoxynivalenol on growth, but is ineffective against the effect of zearalenone.

Cím:Urinary deoxynivalenol (DON) and zearalenone (ZEA) as biomarkers of DON and ZEA exposure of pigs / S. Thanner, Czeglédi Levente, H. E. Schwartz-Zimmermann, F. Berthiller, A. Gutzwiller
Dátum:2016
ISSN:0178-7888 1867-1632
Megjegyzések:Four diets contaminated with 1.1 to 5.0 mg/kg deoxynivalenol (DON) and 0.4 to 2.4 mg/kg zearalenone (ZEA) were fed to four groups of six growing Large White pigs. Urine samples were collected after 3 to 4 days and again after 6 to 7 days on the diets. On each sampling day, half of the animals were sampled in the morning, after an 8-h fast, and the other half were sampled in the afternoon, after 7 h of ad libitum access to feed. The urinary concentrations of DON, DON-glucuronide, DON-3-sulphate, de-epoxy-DON, as well as of ZEA, ZEA-14-glucuronide, ?-zearalenol and ?- zearalenol-14-glucuronide, analysed using LC-MS/MS, were used to calculate urinary DON and ZEA equivalent concentrations (DONe and ZEAe). The urinary concentration of DONe (P< 0.001), but not of ZEAe (P= 0.31), was lower in the fasted than that in the fed animals. The urinary DONe/creatinine and ZEAe/creatinine ratios were highly correlated with DON and ZEA intake per kg body weight the day preceding sampling (r= 0.76 and 0.77; P<0.001). The correlations between DON intake during the 7 h preceding urine sampling in the afternoon and urinary DONe/creatinine ratio (r =0.88) as well as between mean ZEA intake during 3 days preceding urine sampling and urinary ZEAe/creatinine ratio (r =0.84) were even higher, reflecting the plasma elimination half-time of several hours for DON and of more than 3 days for ZEA. ZEAe analysed in enzymatically hydrolysed urine using an ELISA kit was highly correlated with the LC-MS/ MS data (r= 0.94). The urinary DONe and ZEAe to creatinine ratios, analysed in pooled urine samples of several pigs fed the same diet, can be used to estimate their exposure to DON and ZEA.
