ABSTRACT

This study aims to evaluate effects of inclusion of moringa in Japanese quail diets on laying performance, egg quality, blood parameters, serum biochemical profile, and behavior. One hundred and forty-four Japanese quails, approximately 35-d-old, were distributed in a completely randomized design with four treatments and six replications. Treatments were diet inclusion of 0, 2, 4 and 6% of dried and ground moringa leaves. The inclusion of moringa in diets reduces the quadratic feed intake up to the level of 1.20%, increases weight of eggs with a quadratic behavior up to 3.80%, and linearly increases yolk weight. Yolk color changes with higher levels of inclusion of moringa and resulted in more intense colors. The biochemical profile of quails changed slightly but remains within the normal range. The inclusion of 4% of moringa in diets increases alkaline phosphatase. Regarding cholesterol and triglycerides, diet with 6% moringa inclusion was lower when compared to the others. The behavior of laying quails does not change due to inclusion of moringa in diets. Up to 3.83% of Moringa oleifera can be included in Japanese quail diet to improve egg quality without compromising performance, biochemical profile, blood parameters and behavior.(AU)


O objetivo deste estudo foi avaliar a inclusão de Moringa oleifera na dieta de codornas japonesas sobre o desempenho, a qualidade de ovos, os parâmetros sanguíneos, o perfil bioquímico e o comportamento. Foram utilizadas 144 codornas japonesas, com aproximadamente 35 dias de idade, as quais foram distribuídas em delineamento inteiramente ao acaso, com quatro tratamentos e seis repetições cada. Foram fornecidas dietas com 0, 2, 4 e 6% de folhas desidratadas e moídas de moringa. A inclusão de moringa nas dietas reduziu quadraticamente o consumo até o nível de 1,2%, aumentou o peso dos ovos com comportamento quadrático até o nível de 3,8% e aumentou linearmente o peso da gema. A coloração da gema se intensificou com maiores inclusões de moringa. O perfil bioquímico sofreu alterações leves, mas não saiu dos padrões normais para codornas. A inclusão de 4% de moringa nas dietas aumentou os níveis de fosfatase alcalina. Já a inclusão de 6% reduziu níveis de colesterol e triglicérides. O comportamento das codornas não se alterou com a inclusão de moringa nas dietas. A inclusão de até 3,83% de Moringa oleifera na dieta de codornas japonesas aumenta a qualidade de ovos sem comprometer o desempenho, o perfil bioquímico, os parâmetros sanguíneos e o comportamento delas.(AU)

ABSTRACT

ABSTRACT The aim of this study was to evaluate the effect of Syzygium cumini leaves (SCL) in laying hens diets on productive performance, egg quality and lipid oxidation of yolk. A total of 108 Hysex White laying hens were distributed in a completely randomized design with three treatments and six replicates of six birds each. The treatments consisted of SCL inclusion at dietary levels of 0, 5 and 10 g/kg. There was no significant effect of SCL inclusion on feed intake, laying percentage, weight and egg mass, feed conversion ratio, Haugh units, specific gravity, percentage of yolk, albumen and egg shells and shell thickness. However, the inclusion of SCL significantly influenced the yolk color and yolk lipid oxidation measured by TBARS values. Yolk color increased and TBARS values ​​decreased with the inclusion of SCL. The inclusion of SCL in laying hens diets improves pigmentation and lipid stability of yolk.
