Description

This book is discussing the relationship between nutrition and broiler genotypes. The new broiler genotypes define their optimal genetic expression according to the nutritional requirements. Thus, an experiment was conducted to study the effect of four different feeding regimens and two broiler strains on the productive performance, digestibility of nutrients, carcass quality, and economic evaluation during 1 to 42 days of age.
In total, 392 male broilers were randomly distributed in a factorial arrangement of 2*4, with two commercial broiler strains (Arbor Acres (AA) and Hubbard (Hub)) and four (NRC, Degussa, CVB, and strain guides) different feeding regimens (FR), totaling eight treatments and seven replicates, with seven broilers in each one. The following parameters were evaluated: bodyweight gain (BWG), feed intake (FI), feed conversion ratio (FCR), carcass yield, meat quality, nutrient intake and its correlation with BWG, and economic efficiency.
