Poultry Production in Hot ClimatesNuhad Joseph Daghir The poultry industry continues to expand in the warm regions of the world at a much faster rate than in temperate zones. Not only can it be quickly and easily developed in these hot climates but poultry meat and eggs can serve as important sources of animal protein in those areas of the world that have protein insufficiency. Fully revised and updated, this new edition describes how the detrimental effects of heat stress can be reduced through the manipulation of housing, breeding, nutrition and management, and includes new contributions on controlled-environment housing, waterfowl, and breeding fast-growing broilers. |
