NÍVEIS DE EXTRATO PIROLENHOSO INFLUENCIANDO EM PARÂMETRO DE DESEMPENHO DE CODORNAS JAPONESAS EM POSTURA

In this study, the productive performance of Japanese quails submitted to diets containing different levels of pirolenous extract (EPL) was evaluated. A total of 405 Japanese quails (Coturnix coturnix japonica) with a mean initial weight of 165 g were used in a completely randomized design in five treatments (0, 0,4, 0,8 1,2 and 1,6% of pirolenous extract - EPL ), nine replicates and nine birds per experimental unit. The variables analyzed were feed intake, laying rate, mean egg weight, egg mass, feed conversion per mass and per dozen eggs, relative and absolute weight of the yolk, albumen and bark, as well as the Haugh unit. This study evaluated the effect of the addition of pyroligneous extract at different levels in the diet of Japanese quails on the productive performance. From the obtained results it can be concluded that the level of pirolenous extract to 0,833% was enough to improve the performance and egg quality characteristics of Japanese quails.
