Distillers dried grains with solubles from corn in diet of japanese quails

Abstract

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 Dunnett’s 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 Dunnett’s test, for feed intake, feed conversion per egg mass, specific gravity and digital colorimeter’s 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.

Influence of homeopathy on the quality of eggs of quails stored

“…The parameters L, and b* presented linear behavior as evidenced by the regression equation. According to Bittencourt et al (2019) the color of the yolk comes from the presence of carotenoids (carotenes and xanthophyll), present in the diet, consequently the higher the consumption of foods rich in pigments, the greater the intense coloration of the yolk. According to Giampietro-Ganeco et al (2012) pigmentation in refrigerated eggs is stable and decreases when eggs are stored at room temperature, however in this study, the values of L, a* and b* were higher.…”

“…Egg storage (7 and 14 days) was carried out in a room with natural ventilation, free of direct solar incidence, in a dry and airy place, with a minimum and maximum temperature of 32.8 + -0.2°C and 21.9 + -0.15°C respectively and maximum RH 69 + -1.3% and minimum RH 41.5 + -1.5%. The eggs were identified according to their treatment and weighed individually utilizing a semi-analytical scale of precision of 0.01 g. Egg quality was evaluated using the following measures, following methodologies proposed by Bittencourt et al (2019).…”

Vegetable pigments in sorghum-based diets for laying hens

“…As reported by Botelho et al, (2017) it is possible to completely replace corn with low tannin sorghum in the diet of commercial laying hens without interfering in the productive characteristics of zootechnical performance. The use of alternative ingredients to corn in feed, in addition to a need to reduce costs in egg production, is an opportunity to find other energy sources that replace corn, without harming animal performance (Bittencourt et al, 2019). This fact can be explained by the nutritional composition of the ingredients tested, and due to the diets used to be isonutritive, with this, the laying hens presented similar zootechnical performance.…”

Grãos secos de destilaria de milho na recria de codornas japonesas e sua repercussão na fase de produção

“…As codornas saíram da fase de crescimento com desenvolvimento adequado e a ração fornecida no período de produção foi única, sem a inclusão do DDG, e balanceada para atender às exigências das aves nesse período. Bittencourt et al (2019), avaliando DDG de milho para codornas na fase de postura, não observaram diferença (p > 0,05) para os parâmetros de qualidade do ovo, como o peso do ovo, e porcentagem de cada componente (gema, albúmen e casca), pois as dietas foram isoenergéticas e isoproteícas assim como no presente trabalho. A gravidade específica é um método utilizado para verificar a quantidade de casca depositada, estando relacionada diretamente com a qualidade da casca do ovo (Harder et al, 2008).…”
