Heat Stress in Broiler Chickens and the Effect of Dietary Polyphenols, with Special Reference to Willow ( spp Bark Supplements-A Review.

Over the last decade, there has been a growing interest in the use of a wide range of phytoadditives to counteract the harmful effects of heat stress in poultry. Willow ( spp.) is a tree with a long history.

Development of a new HPLC method used for determination of zearalenone and its metabolites in broiler samples. Influence of zearalenone on the nutritional properties of broiler meat.

This paper presents the development, optimization and validation of a new HPLC method used for the separation and determination of zearalenone, ZON, and its metabolites in biological samples of Leghorn broiler. ZON and its metabolites can be separated with good resolution in 11 min, using a Hypersil Gold C18 column, a mobile phase mixture of 50 mM aqueous ammonium acetate:acetonitrile:methanol, 45:8:47 (v/v/v), flow rate 1 mL/min and column temperature 40 degrees C. Based on the results obtained by this method applied on biological samples one can conclude that liver is the site for zearalenone localization and detoxification.
