Densitometric and biochemical values of broiler tibias at different ages
(Poultry Science Assoc Inc, 2009-12-01)
The objective of this experiment was to determine the normal values of bone radiographic density (BRD) by using the optical densitometry in radiographic images and the biochemical values represented by serum calcium, ash ...
Model to estimate lysine requirements of broilers
(Wageningen Acad Publ, 2010-01-01)
The purpose of this study is to describe the development of a model to predict the digestible lysine requirements of broilers using the factorial approach, and to evaluate the model using as reference the model presented ...
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 ...
Lysine, methionine, phenylalanine, arginine, valine, isoleucine, leucine, and threonine maintenance requirements of broiler breeders
(2015-01-01)
Five hundred and sixty Cobb-Vantress broiler breeders were used to determine the maintenance requirement of dietary Arg, His, Ile, Leu, Lys, Met, Phe, Thr, and Val in 10 21-d assays using the comparative slaughter technique. ...

Image analysis for studying the behaviour of broilers exposed to artificial LED lighting
(2015-01-01)
The photoperiod length and the type of light may influence both growth and behaviour of reared birds. The aim of this study was to evaluate broilers' behaviour when exposed to different LED colours. The study was carried ...
Isolated and combined organic acids in diets of broiler chickens challenged with Eimeria acervulina
(2020-07-01)
This study aimed to evaluate the effect of isolated or combined citric and benzoic acids added to the diets of broiler chickens on performance, allometry of the digestive system organs, intestinal pH and quantity of ...
