The study objective was to evaluate the most commonly used strategies and practices in coccidiosis control in the Americas. Seventy five interviews with participants from Argentina, Brazil, Canada, Colombia, Mexico and Peru were carried out in the period March-April 2014. Nearly half of all broiler production in the region was represented. In respect to the number of rotations, 84% of the respo...

Two 42-d floor pen studies were conducted with commercial broiler chickens to measure the efficacy of 1 ppm diclazuril in the starter or grower diet in shuttle programs with 66 ppm salinomycin. Study 1 compared a salinomycin to diclazuril (starter to grower diet) shuttle treatment with salinomycin to salinomycin, salinomycin to 100 ppm monensin, salinomycin to 99.8 ppm lasalocid, and unmedicate...

Coccidiosis is an infectious parasitic disease of poultry which causes heavy economic losses to commercial industry. has been generally controlled by using different synthetic anticoccidial drugs but, due development resistance these this method losing its effectiveness. Exploration novel and alternative compounds against avian coccidiosis need time now a days. In regard, medicinal plants can s...

Three levels (high, low and control) of northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), were maintained on White Leghorn hens for 24 weeks. The hens were then treated with carbaryl to eradicate the mites, were induced to molt, and were reinfested with mites 9 weeks later. Subsequent levels of mites on the three groups showed that the degree of acquired immunity was related...

This study evaluated the effects of dietary anticoccidial drugs plus antibiotic growth promoters (AGPs) on parameters of immunity in commercial broiler chickens. Day-old chicks were raised on used litter from a farm with endemic gangrenous dermatitis to simulate natural pathogen exposure and provided with diets containing decoquinate (DECX) or monensin (COBN) as anticoccidials plus bacitracin m...

Coccidiosis causes considerable economic losses in the poultry industry. At present, the pathology of coccidiosis is preventable with anticoccidials and vaccination, although at considerable cost to the international poultry industry. The purpose of the present study was to elucidate the relationship between Eimeria tenella development and host cell apoptosis in chickens, which provides a theor...
