Summary: | This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 16052-wk-old Dekalb White hens were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish by-product meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that fish by-product meal can be used in diets for hens as alternative feed, with better results in egg production, feed conversion, egg weight, yolk-albumen ratio and a reduction in feed cost and production cost. Keywords: alternative feed, economic available, feed cost, lipid profile, performance. Objetivou-se com este estudo avaliar a inclusao de niveis crescentes (0, 1, 2 3 e 4%) de farinha de residuo de pescado na dieta de poedeiras comerciais leves sobre o desempenho, qualidade do ovo e analise economica. Foram utilizadas 160 poedeiras da linhagem Dekalb White com 52 semanas de idade. O experimento teve duracao de 84 dias divididos em quatro periodos de 21 dias. O delineamento experimental foi o inteiramente casualizado com cinco tratamentos contendo quatro repeticoes de oito aves cada. As estimativas dos niveis de farinha de residuo de pescado foram determinadas por meio de regressao polinomial. Foram observadas diferencas (p < 0,05) em todas as variaveis de desempenho, no peso do ovo, percentagem de gema e albumen, altura de gema e albumen, custo alimentar e custo de producao, onde a inclusao de farinha do residuo de pescado proporcionou melhores resultados. Concluiu-se que a farinha de residuo de pescado pode ser utilizada como alimento alternativo em racoes para poedeiras comerciais leves, proporcionando melhora na producao de ovos, conversao alimentar, peso do ovo, relacao gema-albumen, reducao no custo alimentar e no custo de producao. Palavras-chave: alimento alternativo, custo, desempenho, perfil lipidico, viabilidade economica. |
