Coconut Cake in Diets for Quail in the Laying Phase

ABSTRACT Currently, agro-industrial by-products have increasingly been used in animal feeding, as they constitute an alternative source of nutrients for the animal diet and a way to simultaneously reduce environmental pollution. The objective of this study was to examine increasing levels of inclusi...

The objective of this study was to examine increasing levels of inclusion of coconut cake in Japanese quail diets in the laying phase on their production performance and egg quality. A total of 360 Japanese quails were allotted to eight treatments with nine replicates and eight birds per experimental unit, in a randomized-block design. Five diets were formulated: a diet without inclusion of the by-product; and diets containing 3, 6, 9, and 12% coconut cake. The experiment lasted 63 days, with evaluations occurring at every 21 days. The following variables were analyzed: feed intake, laying rate, feed conversion, egg weight, specific gravity, Haugh unit, yolk, albumen and shell percentage, shell thickness, and shell weight. The treatments elicited a positive linear response from laying rate, whereas feed conversion per egg mass decreased linearly. In terms of egg-quality traits, shell percentage was influenced, increasing linearly. Coconut cake inclusion at 12% in the diet of Japanese quail in the laying improved feed conversion per egg mass and increased egg-laying rate and eggshell percentage.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-635X2020000100306&lng=en&tlng=enalternative feedpoultryproduction performance
