ABSTRACT
O objetivo do trabalho foi avaliar diferentes níveis de inclusão de farelo de algodão na alimentação de codornas japonesas. Foram utilizadas 240 codornas japonesas distribuídas em delineamento inteiramente casualizado com cinco tratamentos e seis repetições, com oito codornas por repetição. Os tratamentos utilizados foram: dieta basal com 0% de farelo de algodão; inclusão de 4% de farelo de algodão; 8% de farelo de algodão; 12% de farelo de algodão e 16% de farelo de algodão. Foram avaliados o consumo de ração individual (g/ave/dia), taxa de postura (%), conversão alimentar por dúzia de ovos (kg/dz), conversão alimentar por massa de ovos (kg/kg), viabilidade das aves, ganho de peso. As variáveis para a qualidade do ovo foram: peso do ovo (g), peso da gema (g), peso da casca (g) peso do albúmen, participação percentual da gema, casca e albúmen, gravidade específica (g/cm3). Para consumo individual de ração (g/ave/dia), peso de gema (g), albúmen, percentual da gema, casca e albúmen houve influência (P<0,05) do farelo de algodão na dieta, para as demais variáveis não foi observada diferença significativa (P>0,05). O farelo de algodão pode ser adicionado na dieta de codornas japonesas, sem prejudicar o desempenho e a qualidade dos ovos.(AU)
The objective of this study was to evaluate different levels of inclusion of cottonseed meal in the diet of Japanese quail. Twenty Japanese quails were used in a completely randomized design consisting of five treatments and six replicates, with eight quails per replicate. The treatments used were: basal diet with 0% cottonseed meal; inclusion of 4% cottonseed meal, 8% cottonseed meal, 12% cottonseed meal, and 16% cottonseed meal. Feed intake per egg mass (kg/dz), feed conversion per egg mass (kg/kg), viability of birds, and weight gain were evaluated. The egg quality variables were: egg weight (g), yolk weight (g), eggshell weight (g) albumen weight, percentage of yolk, eggshell and albumen, and specific gravity (g/cm3). Cottonseed meal in the diet influenced (P<0.05) individual feed intake (g/bird/day), yolk weight (g), albumen, and percentage of yolk, eggshell and albumen. No significant difference was observed for the other variables (P>0.05). Cottonseed meal can be added to the diet of Japanese quail without compromising performance or egg quality.(AU)

The objective of this study was to evaluate different inclusion levels of distillers dried grains with solubles (DDGS) from corn in the diet of quails. A total of 210 japanese quails (Coturnix coturnix japonica) were distributed in a completely randomized design of five treatments and six replicates, with seven quails per experimental unit. The treatments used were: control feed; inclusion of 5, 10, 15 and 20% of DDGS. The variables assessed were: feed intake, feed conversion per dozen and egg mass, egg production, egg weight, specific gravity, yolk color and economic analysis. Data were analyzed by regression model and Dunnetts test at 5% probability. For individual feed intake, laying rate, and feed conversion per egg mass, specific gravity and yolk color by color fan, there was effect caused by inclusion of DDGS (p < 0.05), but the other variables did not show significant difference. By Dunnetts test, for feed intake, feed conversion per egg mass, specific gravity and digital colorimeters L parameter, there was effect (p < 0.05). As for economic analysis, DDGS presented low cost. It can be concluded that DDGS can be used in feed at a 20% level without impairing the performance and quality of quails eggs.
