Whole and ground grain sorghum and the free choice feeding system in broiler diets

Abstract: This experiment evaluates the zootechnical performance, yield of cuts, carcass composition, and intake of metabolizable energy, lysine, and methionine + cystine in male broilers from 21 to 42 days of age fed diets based on whole and ground grain sorghum and corn. A total of 112 birds of the Cobb 500 lineage were divided into 28 cages (four animals per cage) in a completely randomized design with four treatments and seven replications. Treatments consisted of diets based on ground corn and soybean meal (control… Show more

“…The beneficial impact of whole-grain diets on livestock nutrition is well-documented [ 1 , 2 , 3 , 4 ]. In poultry feed, wheat [ 5 ], barley [ 6 ], maize [ 7 ], and sorghum [ 8 ] are predominantly used in their whole-grain form. Their positive effects are mainly the improvement of poultry growth performance, particularly the feed intake (FI) and feed conversion ratio (FCR), nutrient and energy utilization, gizzard development, decreased mortality rates, reduced feed production costs, and increased feed mill capacity [ 9 ].…”

“…Já Fagundes et al (2019), ao avaliarem o desempenho zootécnico, o rendimento de cortes, a composição de carcaça e a ingestão de energia metabolizável, lisina e metionina + cistina em 112 frangos de corte machos da linhagem Cobb 500 de 21 a 42 dias de idade alimentados com dietas à base de sorgo inteiro e moído. E sob o sistema de alimentação de livre escolha, constataram que a melhor conversão alimentar foi observada no tratamento com sorgo integral e concentrado separado no alimentador.…”
