This study aimed to evaluate the supplementation levels of an exogenous alpha-amylase in broilers diets and compare two indicators in determining the diets energy. The experiment was divided into two parallel evaluations, being one of performance and the other of metabolism. In performance assay, 1,700 one-day-old Cobb-500 male chicks were used. The animals were dis.. Read More»

The bean represents the main source of proteins for the low income populations, although the digestibility of those proteins is relatively low. Consequently, the programs of plant genetic breeding have been working on the search for new lines with higher protein levels. Thus, with the purpose of supplying information to the researchers, in this study, 21 bean (Phase.. Read More»

This study aimed to evaluate the concentration effects of two vitamin D isoforms, cholecalciferol (D3) and 25-hydroxycholecalciferol (25-OHD3) in broilers diets on performance, bone and physiological features of these birds. Of a total of 1920 one-day-old male chicks Cobb-500 were used from commercial hatchery, reared under bed creation systems. The animals were dis.. Read More»
