Natural shading and productivity index of broiler chickens
(2015-01-01)
The appropriate use of natural resources in the design of broiler houses provides a reduction in farming operating costs and optimization of production conditions. Therefore, the natural shading around the broiler house ...
Effect of indomethacin on hyperthermia induced by heat stress in broiler chickens
(Springer, 1998-12-01)
An investigation was carried out to verify whether the heat stress hyperthermia response of broilers is prostaglandin-dependent. Male broiler chickens of the Hubbard-Petterson strain, aged 35-49 days, were used. Chickens ...

Evaluation of tibial dyschondroplasia development in broiler chickens fed diets containing 25 hydroxicolecalciferol
(2012-12-01)
This research was carried out to evaluate the development of tibial dyschondroplasia (TD) in broilers from 1 to 21 days. Four hundred forty day-old male chickens, from broiler breeders aged 60-62 weeks, were randomly ...
Digestibility of feeds containing sorghum, with and without tannin, for broiler chickens submitted to three room temperatures
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2004-03-01)
The traditional method of total excreta collection was applied, using 30 to 40 day old male Ross 308 broiler chickens. One hundred and eight broiler chickens were used, randomly assigned to a 3x3 factorial experimental ...
Air velocity and exposure time to ventilation affect body surface and rectal temperature of broiler chickens
(Applied Poultry Science Inc, 2000-03-01)
Increasing air movement over poultry by using fans (ventilation) has become an accepted means of reducing environmental heat stress over the last several years. The purpose of this study was to evaluate the effect of air ...
