“…(2013) also reported that AFs caused dramatic reduction in feed intake of meat ducks; reduced feed intake could then lead to decreases in body weight and weight gain. Yang et al. (2014) also found that AF reduced utilization efficiencies of meat ducks with respect to energy and protein feed.…”

This study aims to evaluate the effects of aflatoxins on growth performance and skeletal muscle of Cherry Valley meat male ducks as they grow and develop. One-day-old healthy meat male ducks (n = 180) were randomly divided into 2 groups; there were 6 replicates in each group and 15 ducks in each replicate. The control group was fed a basic diet, and the experimental group was fed a mold-exposed cottonseed meal diet containing aflatoxins instead of normal cottonseed meal. The experimental period was 35 days, and divided into two stages of 1 to 14 days (early stage) and 15 to 35 days (late stage). During the experimental period, live weight, breast muscle weight and thigh muscle weight of meat male ducks were measured weekly. Results showed as follows: 1) aflatoxins contained in the mold-exposed diet significantly reduced daily weight gain and feed intake, and increased feed-to-gain ratio of meat male ducks at different ages (P < 0.05); 2) the Gompertz equation (Wt = Wm exp {−exp [−B (t − t*)]}) could successfully fit the growth curve and growth and developmental patterns of skeletal muscles of Cherry Valley meat male ducks (R2 ≥ 0.97); 3) the relationship between chest muscle and live weight was the best described by a power regression and polynomial regression (R2 = 0.99); the relationship between live weight and thigh muscle weight was the best described by linear regression, polynomial regression, and power regression (R2 = 0.99); 4) aflatoxins in the mold-exposed diet significantly reduced live weight, breast muscle weight and thigh muscle weight of Cherry Valley meat male ducks at various ages; and 5) aflatoxins delayed the age at peak in growth of meat male ducks, and reduced weights at the peak for breast muscle, thigh muscle and whole body as well as the maximal daily weight gain. In summary, aflatoxins delayed growth of Cherry Valley meat male ducks and development of skeletal muscle.

“…TRAVEL, J.-D. BAILLY, P. GUERRE Les résultats obtenus lorsque différentes mycotoxines sont administrées en mélange avec l'une d'entre elles à des doses toxiques semblent révéler un nombre limité d'interactions. Ainsi, l'administration d'AFB1 à des doses reconnues toxiques associée à des doses non toxiques de fusariotoxines, ne semble pas révéler d'interaction majeure entre ces composés (Lee et al 2012aet b, Wan et al 2013, Siloto et al 2013, Yang et al 2014. Des résultats déjà anciens réalisés avec l'OTA associée à des fusariotoxines vont dans le même sens.…”

Les mycotoxines sont des métabolites secondaires produits par des champignons, qui peuvent être présents sur une large variété de cultures et en particulier les céréales. Leur maitrise est considérée comme un enjeu majeur dans le monde agricole en raison de leurs effets nocifs sur la santé des Hommes et des animaux. Bien que plus de 400 mycotoxines aient été identifiées, seules quelques-unes sont préoccupantes en production avicole. L’Union Européenne applique ou recommande des teneurs maximales pour certaines mycotoxines dans les matières premières et les aliments pour volailles, afin de protéger les animaux et le consommateur humain. L’objectif de cette revue, est de présenter les effets d’expositions aiguës ou réitérées aux mycotoxines, sur la santé et les performances dans les principales espèces avicoles. Cette analyse est notamment réalisée, lorsque cela a été possible, en comparant les effets observés lors d’études récentes aux seuils réglementés/recommandés au niveau européen. Une attention particulière a été portée sur l’importance des facteurs d’espèces et stades de productions, quant à la sensibilité aux différentes toxines. Le dernier paragraphe est consacré à l’analyse des données disponibles en cas de multi-contaminations en termes d’effets additifs, synergiques ou antagonistes.

“…By contrast, combined effects of low levels/doses of toxins are more likely but less well understood [7,8,9,10,11]. Most studies on the combined effects of mycotoxins were done using aflatoxin B1 in association with FUS [12,13,14,15,16,17]. Only very few studies have investigated the combined effects of FUS in poultry.…”

Fusarium mycotoxins (FUS) occur frequently in poultry diets, and regulatory limits are laid down in several countries. However, the limits were established for exposure to a single mycotoxin, whereas multiple contamination is more realistic, and different studies have demonstrated that it is not possible to predict interactions between mycotoxins. The purpose of this study was thus to compare the toxic effect of deoxynivalenol (DON), fumonisins (FB) and zearalenone (ZON), alone and in combination on broiler chickens, at the maximum tolerated level established by the EU for poultry feed. Experimental corn-soybean diets incorporated ground cultured toxigenic Fusarium strains. One feed was formulated for chickens 0 to 10 days old and another for chickens 11 to 35 days old. The control diets were mycotoxin free, the DON diets contained 5 mg DON/kg, the FB diet contained 20 mg FB1 + FB2/kg, and the ZON diet contained 0.5mg ZON/kg. The DONFBZON diet contained 5, 20, and 0.5 mg/kg of DON, FB1 + FB2, and ZON, respectively. Diets were distributed ad libitum to 70 broilers (male Ross PM3) separated into five groups of 14 chickens each reared in individual cages from one to 35 days of age. On day 35, after a starvation period of 8 h, a blood sample was collected, and all the animals were killed and autopsied. No difference between groups that could be attributed to FUS was observed in performances, the relative weight of organs, biochemistry, histopathology, intestinal morphometry, variables of oxidative damage, and markers of testicle toxicity. A significant increase in sphinganine and in the sphinganine to sphingosine ratio was observed in broilers fed FB. Taken together, these results suggest that the regulatory guidelines established for single contamination of broiler chickens fed with DON, FB, and ZON can also be used in the case of multiple contamination with these toxins.
