Effects of the Hydrolysable Oak Tannins on the Quail Performance

Abstract

In the present study effects of different levels of hydrolyzed oak tannin on Japanese quail, live body weight and live body weight gain, food intake, food conversion efficiency and mortality rate were investigated. Therefore, a total of 240 quails were weighed and divided into 4 treatment groups each with 3 replicates containing 20 birds and reared in flat for 42 days as experimental period. While one of the groups was fed control diet with no additives (0% tannin A), other groups were fed with the different percentages of tannin on their diets, which are 0.5% (B), 1.0% (C), 1.5% (D) respectively. It has been observed that Japanese quails that fed the oak tannin containing diet had slower growth rate and poorer feed conversion efficiency and high mortality rate than birds fed with a tannin-free diet.

Bem-estar e qualidade de ovos de codornas alimentadas com extratos de camomila e passiflora

“…Entretanto, um ponto que pode tornar negativa a inclusão dos extratos de camomila e de passiflora na alimentação de aves é o fato de ambos conterem taninos e outros compostos fenólicos que podem, dentre alguns problemas, levar a prejuízos quanto ao ganho de peso, aumento no consumo de ração e piora na conversão alimentar (Emani et al, 2012;Karaman et al, 2016;Sinaei e Houshmand, 2016).…”
