Resumo

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)

This study aimed to evaluate visual contamination rates of carcasses of broilers slaughtered in establishments supervised by the Federal Inspection Service (SIF) and efficiency of carcass washing in replacement of trimming. The work was divided into three parts: analysis of partial and total carcass condemnation by contamination in hot (October to March) and cold (April to September) periods; evaluation of microbiological contamination before and after washing 800 carcasses (400 that did not go through washing x 400 that went through washing); and carcass washing test. For the test, twenty carcasses were evaluated in five treatments: carcasses without contamination - before washing; carcasses without contamination - after washing; contaminated carcasses - before washing and before trimming; contaminated carcasses - after washing; contaminated carcasses - after trimming. Hot and cold periods obtained a similar number and weight of slaughtered chickens. There were no differences regarding condemnation by contamination. Periods of the year did not influence the average weight of the birds slaughtered in the state of Mato Grosso do Sul. Carcass washing in the slaughter line was effective in reducing total bacterial contamination, E. coli, and enterobacteria. There is a similarity in the reduction of condemnations by contamination, evidencing that the uniformity of production systems. Although it is not yet a reality in Brazilian slaughterhouses, the washing procedure can be considered a safe replacement for trimming.(AU)

Resumo

Avaliou-se nível de lisina digestível para 1050 frangos de corte dos 12 aos 22 dias de idade. O delineamento experimental foi inteiramente ao acaso, com cinco tratamentos, sete repetições e 30 aves por unidade experimental. Os tratamentos foram: 1,05; 1,10; 1,15; 1,20 e 1,25 por cento de lisina digestível. Avaliaram-se ganho de peso, consumo de ração, conversão alimentar, composição e deposição de nutrientes corporais. Foram constatados efeitos quadráticos de lisina digestível no consumo de ração e resposta linear ascendente no peso da carcaça. Na composição química da carcaça, houve resposta quadrática do nível de lisina na concentração de proteína. As taxas de deposição proteica, deposição de água, da carcaça e do corpo total tiveram aumento linear em resposta ao acréscimo de lisina na dieta. O aumento da concentração de lisina, todavia, coincidiu com a redução da matéria mineral nas vísceras e sangue e no corpo total. Considerado o desempenho, o nível 1,1 por cento de lisina digestível atendeu às necessidades do frango de corte entre o 12º e o 22º dia de idade. Consideradas a composição química e as taxas de deposição dos nutrientes corporais, a demanda pelo aminoácido digestível torna-se igual ou maior que 1,25 por cento.(AU)


The lysine level was evaluated for 1,050 male broilers from 12 to 22 days of age. The experimental design was completely randomized with five treatments, seven replications, and 30 birds per experimental unit. The treatments were: 1.05, 1.10, 1.15, 1.20, and 1.25 percent of digestible lysine. Weight gain, feed intake, feed: gain ratio, body composition, and nutrient deposition were measured. There were quadratic effects of digestible lysine on feed intake and an ascendant linear effect on carcass weight. In the carcass chemical composition, there was a quadratic response of lysine level in protein concentration. The deposition rates in carcass protein, carcass water, and whole body had a linear increase as response to lysine addition to diet. The lysine level increase however coincided with the mineral decrease on blood, offal, and whole body. Basing on performance, the digestible lysine 1.1 percent level attended the broiler needs from 12 to 22 days of age. On the other hand, considering the chemical composition and the nutrient accretion rates, the need for digestible amino acid was equal or higher than 1.25 percent.(AU)
