An experiment was carried out to evaluate the effect of the inclusion of 20% whole-grain or ground pearl millet (PM) in mash and pelleted diets on the performance, carcass traits, and organ weights of broilers reared until 21 days of age. A randomized block experimental design in a 3 x 2 factorial arrangement (diets containing corn and soybean meal, whole-grain PM, or ground PM x mash or pelleted diets), with five replicates per treatment and 10 birds per experimental unit, was applied. Diets were analyzed for mean geometric diameter, geometric standard deviation, pellet hardness, and density. Broiler performance, carcass yield, and organ weights were evaluated. On day 21, one bird with the average weight of each experimental unit was sacrificed for carcass evaluation. It was concluded that both as whole-grain and ground PM can be added to the diet of broilers up to 21 days of age. The dietary inclusion of PM results in higher abdominal fat deposition. Broilers fed the pelleted diets presented lower feed intake, better feed conversion ratio, lower gizzard and heart percentages, and higher carcass weight.(AU)
