“…Our results agree with those reported by Moura et al (2010a), who evaluated the replacement of corn by sorghum at equidistant levels for Japanese laying quail and concluded that replacing 100% of low-tannin sorghum with corn is a viable practice.…”

“…Of the most commonly used substitutes, low-tannin grain sorghum stands out for its chemical profile that is similar to that of corn, for being economically viable, and for not compromising poultry performance. However, the sorghum is deficient in xantophils and carotenoids, and its inclusion in diets reduces the color intensity of the quail egg yolk (Moura et al, 2010a).…”

Corn is the major energy ingredient in diets, and many ingredients have been tested aiming to replace it. In this regard, sorghum stands out for its chemical profile similar to that of corn. However, because it is low in carotenoids, its inclusion in diets reduces the egg yolk color pigmentation, which can be corrected by the addition of synthetic pigments. This study aimed to evaluate the performance and egg quality of Japanese quail (Coturnix japonica) supplemented with red (canthaxanthin) and yellow (apo-ester 10%) synthetic pigments. A total of 150 quail at 70 days of age were distributed according to the experimental diet [R1: corn-based control diet (DC); R2: sorghum-based diet (DS); R3: DS + yellow; R4: DS + yellow + red; and R5: DS + red] with six replications and five birds per experimental unit, for 28 days. Performance, egg quality, yolk color, and feed cost characteristics were evaluated. Regression equations were estimated for the effects of color as a function of periods, and treatment means were compared by Tukey's test at 0.05 probability. There was no significant effect (P>0.05) of additives on the quail productive traits. However, addition of synthetic pigments significantly improved the chromatic profile of the yolks (P<0.05). Inclusion of synthetic pigments improves yolk color, but should be evaluated according to market demands.

“…However, even 3% supplementation level was not enough to reach values usually obtained with corn use. Moura et al (2010), working with corn replacement by sorghum in quail diets, reported that the yolk colour linearly decreased as sorghum level increased in diets. According to the authors, yolk colour, determined by using the colorimetric fan, was 7.21, 6.52, 5.56, 3.88 and 1.48, respectively for 0, 25, 50, 75 and 100% corn replacement by sorghum.…”

However, the inclusion of a yolk pigment is recommended in sorghum-based rations (Moura, Fonseca, Rabello, Takata, & Oliveira, 2010). Yolk colour is an important factor in consumers' acceptance of a product, and many companies use synthetically produced carotenoids to meet the high demands of the global market (Yaakob, Ali, Zainal, Mohamad, & Takriff, 2014).…”

ABSTRACT. This study was carried out to evaluate the effects of pequi peel flour (PPF) in the diet of laying Japanese quails on their productive performance and on the quality and cost of the eggs produced. A total of 160 quail (Coturnix coturnix japonica) were distributed in a completely randomized design with four treatments and five replicates with eight birds each. Treatments consisted of different levels of PPF (0, 1, 2 and 3%) in a commercial diet based on sorghum. Evaluated parameters were productive performance (daily feed intake, laying rate, egg weight, egg mass and feed conversion rate), egg quality (yolk, albumen and eggshell weight and measures, yolk colour, ash and calcium content of eggshell, specific weight, Haugh unit, and nutrient content of the egg) and average cost of the production. PPF did not affect (p > 0.05) productive performance and nutritional composition, quality or average cost of the eggs; however, yolk colour was linearly increased (p < 0.05) with the PPF levels in the diets. It was concluded that PPF might be included in the commercial diets of Japanese quails up to 3% due to the improvement in yolk colour.Keywords: alternative feed for quails, Caryocar brasiliense Camb., pequi by-product.Farinha de casca de pequi em dietas para codornas japonesas RESUMO. Este estudo foi realizado para avaliar os efeitos da farinha de casca de pequi (FCP) em dietas para codornas japonesas sobre o desempenho produtivo, a qualidade dos ovos e o custo dos ovos produzidos. Foram distribuídas 160 codornas (Coturnix coturnix japônica) em um delineamento inteiramente casualizado com quatro tratamentos e cinco repetições com oito aves cada. Os tratamentos consistiram de níveis de FCP (0, 1, 2 e 3%) em ração comercial à base de sorgo. Os parâmetros avaliados foram o desempenho produtivo (consumo de ração diário, taxa de postura, peso do ovo, massa de ovo e conversão alimentar), a qualidade do ovo (peso e medidas de gema, albúmen e casca dos ovos, cor da gema e teores de minerais e de cálcio da casca do ovo, peso específico, unidade Haugh e teor de nutrientes dos ovos) e o custo médio da produção. A FCP não afetou (p > 0,05) o desempenho produtivo, a composição nutricional, a qualidade e o custo médio dos ovos, entretanto, a cor da gema aumentou linearmente (p < 0,05) devido ao aumento dos níveis de FCP nas dietas. Concluiu-se que a FCP pode ser incluída nas dietas comerciais para codornas Japonesas até 3% por melhorar a cor da gema.Palavras chave: alimento alternativo para codornas, Caryocar brasiliense Camb., subproduto do pequi.

“…Quail farming is a poultry activity in expansion, responsible for the generation of jobs and income at all levels of the production chain, and its main products are eggs and meat, which are source of animal protein with high biological value (Moura et al, 2010). Quail farming stands out for the precocity, high laying rate of the birds and the small size required for the production (Guimarães et al, 2014).…”

A B S T R A C TThe objective of this study was to determine the effects of environment and electrolyte balance on environmental, physiological and productive indices of Japanese quails. For the experiment, 288 quails were distributed in a randomized block design with six treatments and six replicates of eight birds per experimental unit. The treatments consisted of one basal feed with 20.0% of crude protein (CP) and the others with a reduction of 3.0% CP to achieve six electrolyte balance levels (166.54; 153.47; 139.63; 139.63; 117.13 and 166.49). As to the environment, there was an increase in air temperature and temperature-humidity index at the hottest hours of the day, causing discomfort to the birds, which increased respiratory rate, but with the maintenance of homeothermy. Differences were observed in feed consumption, water consumption, production, weight of eggs and mass of eggs, due to the electrolyte levels in the feed. For feed conversion, both per mass and per dozen of eggs, there was no statistical difference. The electrolyte balance and environmental indices at the hottest hours of the day did not affect quail production.Índice de conforto térmico, variáveis fisiológicas e desempenho de codornas alimentadas com redução proteica R E S U M O Objetivou-se, neste trabalho, determinar o efeito do ambiente e do balanço eletrolítico sobre os índices ambientais, fisiológicos e produtivos de codornas japonesas. Utilizaram-se 288 aves distribuídas no delineamento em blocos casualizados com seis tratamentos e seis repetições de oito aves por unidade experimental. Os tratamentos consistiram em uma ração basal com nível de 20,0% PB e os demais com redução de 3,0% PB, para alcançar seis níveis de balanço eletrolítico (166,54; 153,47; 139,63; 139,63; 117,13 e 166,49). Quanto ao ambiente, verificou-se uma elevação na temperatura do ar e no índice de temperatura e umidade nos horários mais quentes do dia, causando desconforto às aves, que elevaram a frequência respiratória, porém com a manutenção da homeotermia. Foram observadas diferenças no consumo de ração, consumo de água, produção, peso e massa de ovo, em razão dos níveis eletrolíticos da ração. Quanto à conversão alimentar tanto por massa quanto por dúzia de ovos, não foi observada diferença estatística. O balanço eletrolítico e os índices ambientais nos horários mais quentes do dia não interferiram na produção das aves.
