“…The ideal values of specific gravity of hen eggs cannot be inferior to 1.080g/cm³ (SILVA, 2004). For quail eggs, the literature has described specific gravity values between 1.074 to 1.076 g/cm³, as found by Muniz et al (2015) for eggs produced by quails fed three different commercial diets, during the laying period from 22 to 31 weeks of age. As in Lima et al (2015), for quails of 26 to 35 weeks of age, values of 1.072 and 1.073 g /cm³ were found.…”

Sixty fresh hen eggs and 60 quail eggs were used in an experiment conducted at UFRRJ in order to survey the correlation between the eggshell quality measurements by average of the following parameters: specific gravity, breaking strength, percentage and thickness of the shell. For hen eggs, specific gravity demonstrated a higher correlation (p <0.05) with shell thickness as compared to other methodologies; the breaking strength correlated with the shell percentage and shell thickness. In quail eggs, there was no correlation (p> 0.05) between specific gravity with the other shell quality analyses. There was a correspondence between breaking strength with the percentage and the thickness of the shell, this ratio was higher for the percentage of shell. For hen eggs, the measurement of the specific gravity method used in commercial poultry farms was adequate to indicate good shell quality in accordance with great correlation with shell thickness. However, the evaluation of shell quality through the specific gravity for quail eggs needs adaptation in the methodology for egg morphology for this species. The parameters of shell quality surveyed: specific gravity, breaking resistance, percentage of shell and thickness of shell in hen eggs showed a positive correlation to a moderate degree (0.54). For quail eggs, the shell percentage shows moderate match (0.60) only with breaking strength and shell thickness.

“…Já os níveis de PB influenciaram somente a produção de OC das codornas que receberam as rações com sorgo, com as médias apresentando comportamento quadrático, sendo a maior porcentagem encontrada com o nível de 21,69% de PB (Figura 1). Muniz et al (2015), não encontraram diferenças significativas entre em rações comerciais para codornas com diferentes níveis proteicos (19, 20 e 21%), porém utilizando milho na ração.…”

Palavras chave adicionaisAlimento alternativo. Desempenho. Qualidade de ovos.resUMo Objetivou-secom esta pesquisa avaliar níveis de proteína bruta em rações com milho ou sorgo sobre o desempenho e qualidade de ovos de codornas japonesas na fase de postura. Foram utilizadas 320 codornas com idade inicial de 14 semanas. O delineamento experimental utilizado foi o inteiramente casualizado em esquema fatorial 2 x 5, sendo 2 alimentos (milho e sorgo) e 5 níveis de proteína bruta (16, 18, 20, 22 e 24%), totalizando 10 tratamentos com 4 repetições e 8 aves por unidade experimental. Foram avaliadas as variáveis de desempenho e de qualidade dos ovos. Houve efeito quadrático dos níveis de proteína bruta (PB) sobre o consumo de ração, conversão alimentar por dúzia e por massa, peso dos ovos, índice de albúmen e peso específico. A ração com milho proporcionou melhor produção de ovos e de ovos comercializáveis em relação à ração com sorgo quando o nível de PB utilizado foi de 16%. Houve efeito quadrático de níveis de PB sobre a produção de ovos totais e comercializáveis somente das aves que receberam ração com sorgo. Conclui-se que o sorgo pode substituir na totalidade o milho nas rações para codornas japonesas. Rações com sorgo devem conter 21,7% de proteína bruta para maior produção de ovos e 19,38% de proteína bruta para maior peso específico dos ovos.inforMation Cronología del artículo. sUMMarYThe objective of this research was to evaluate crude protein levels in corn or sorghum rations on performance and quality of Japanese quail eggs in the laying phase. We used 320 quails with an initial age of 14 weeks.The experimental design was completely randomized in a 2 x 5 factorial scheme, with 2 foods (maize and sorghum) and 5 crude protein levels (16, 18, 20, 22 and 24%), totaling 10 treatments with 4 replicates and 8Birds per experimental unit. The performance and egg quality variables were evaluated. There was a quadratic effect of crude protein (CP) levels on feed intake, feed conversion per dozen and by mass, egg weight, albumen index and specific weight. The corn ration provided better marketable egg and egg production in relation to the sorghum ration when the CP level used was 16%. There was a quadratic effect of CP levels on the production of total and marketable eggs only of the birds that received feed with sorghum. It can be concluded that sorghum may substitute maize in Japanese quails. Sorghum feed should contain 21.7% crude protein for higher egg production and 19.38% crude protein for higher egg weight. additional keYwords Alternative food. Performance. Egg quality.

“…Brazilian quail breeding is becoming ever more prominent in the aspects of rearing and nutrition, transitioning from a family activity to a commercial-scale production. Advances in production technological innovations, especially in feeding programs, ensure that nutritional requirements are met, leading to good performance (Muniz et al, 2015).…”

The objective of this study was to evaluate the effect of the inclusion of canola and coconut oils to diets of European quail (Coturnix coturnix) over performance and carcass yield. One hundred and ninety-two quail (eight-days old) were randomly allocated to four dietary treatments with six replicates of eight birds each. The treatments were arranged in a factorial 2×2 scheme with two sources of dietary oil containing two levels of canola and coconut oils (1 and 2%). For performance variables, the final weight was evaluated, and the carcass variables were feed intake, weight gain, and feed conversion. A significant difference was observed between treatments for feed intake, with the inclusion of 2% canola oil providing higher intake. There was also significant effect for carcass characteristics on weight at fasting, eviscerated carcass, liver and gizzard weights, as well as liver, heart, and gizzard yields. The inclusion of vegetable oil such as canola and coconut oils in diets for European quail at the levels of 1 and 2% can be performed with no negative effect on performance from 8 to 42 days of age.
