Abstract
Deoxynivalenol (DON), a well-known contaminant of feed, can have negative effects on gut permeability and function in poultry, which then could affect major and trace element content of the broilers’ breast and thigh muscles, and ultimately reduce meat quality. To study this hypothesis, DON-contaminated diet was fed to broiler chicks. Two groups of birds were housed in metabolic cages with free access to water and feed, with or without DON (10 mg/kg). After 5 weeks, birds were dissected and samples of the breast and thigh muscles, feed and droppings were analysed for five macro (Ca, K, Mg, Na, and P) and ten micro elements (Al, Cr, Cu, Fe, Mn, Li, Mo, Ni, Pb, Rb, and Zn) by inductively coupled plasma optical emission spectrometry (ICP-OES) or inductively coupled plasma mass spectrometer (ICP-MS) methods. In both groups, increased (p < 0.05) concentrations of Ca Na, Fe, Mn, and Zn were found in thigh muscles compared with the breast, whereas the concentrations of Mg, P, and Rb were higher in the breast muscles. DON had no effect on the elemental contents of the broilers’ breast and thigh muscles. In conclusion, DON at a level of 10 mg/kg feed to broiler chicken over of 5 weeks did not alter the macro or micro element composition in muscle meat.
Highlights
It is known that chickens have a higher tolerance to DON than other animals and are frequently exposed to DON through their cereal-rich diet (Ghareeb et al 2015; Osselaere et al 2013; Eriksen and Pettersson 2004)
The present experiment was conducted to investigate the impact of feeding high-dosed DON (10 mg DON/kg feed) on the concentrations of 15 mineral elements in the breast and thigh muscles of broiler chickens
The ratio of the amount of element in the droppings to its amount in the feed for control and DON-fed birds (Table 2) can be used as an indicator for the net result of mineral absorption and endogenous excretion in relation to feed concentration. This ratio was numerically decreased when DON was added to the feed of broiler chicken for micro or macro elements suggesting that DON may reduce the digestibility and absorption of elements
Summary

The present experiment was conducted to investigate the impact of feeding high-dosed DON (10 mg DON/kg feed) on the concentrations of 15 mineral elements in the breast and thigh muscles of broiler chickens.
