- Fish by-product meal in diets for commercial laying hens André Ferreira Silva Frank George Guimarães Cruz João Paulo Ferreira Rufino Waldo Mateus Plácido Miller Nathália Siqueira Flor Rafael Torres Assante Agrociencias feed cost performance lipid profile Alternative feed economic available 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. 2017 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303153751008 https://www.redalyc.org/journal/3031/303153751008/ https://www.redalyc.org/journal/3031/303153751008/html/ https://www.redalyc.org/journal/3031/303153751008/303153751008.epub https://www.redalyc.org/journal/3031/303153751008/movil 10.4025/actascianimsci.v39i3.34102 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
