The objective of this study was to measure the zootechnical performance and egg quality of Japanese quails housed at different densities and fed diets containing yeast cell walls (YCWs). Five hundred and seventy-six quail (Coturnix coturnix japonica) were distributed at 43 weeks of age, and 76% were laid, with an initial weight of 158.50 ± 5.41 g, in a completely randomized design in a 3 × 2 factorial arrangement (three YCW levels: 0, 500, and 750 g.ton−1 and two housing densities: 81.5 and 92.4 cm2/quail), with six replicates of 17 and 15 quail per experimental unit, respectively. The following parameters were evaluated: feed intake, egg production/bird/day, egg production/housed quail, marketable egg production, egg mass, feed conversion per dozen eggs, egg mass and viability, egg weight, specific egg weight, percentage of yolk, albumen and shell, and shell thickness. The means of the three cycles of 21 days were subjected to analysis of variance using the statistical software Sisvar. There was no significant interaction effect between YCW inclusion level and cage density on zootechnical performance parameters or egg quality, except for egg weight, which suggested that YCW addition, regardless of cage density, did not affect the results. It was observed that the eggs of quails housed in cages with 92.4 cm2/bird feed and 500 g.ton1 YCW had greater egg weights. Shell thickness was independently influenced by cage density, and the lowest density (92.4 cm2/bird) promoted greater shell thickness. The inclusion of 500 g.ton1 of yeast cell wall material in the diet of Japanese quails housed at a density of 92.4 cm2/bird improved egg weight and shell thickness without negatively affecting the other parameters of egg quality or zootechnical performance.

“…Nos últimos anos, a coturnicultura vem se desenvolvendo em ritmo acelerado destacando-se como importante atividade produtiva do segmento da avicultura nacional (1) , alcançando altos níveis de produção, resultado das inovações tecnológicas no setor de produção e mudanças nas áreas de genética, nutrição, ambiência e sanidade (2) . Contudo, mesmo nos criatórios mais tecnificados, um dos problemas sanitários mais temidos é o surgimento de Salmonelose no plantel devido principalmente as altas densidades de criação.…”

Resumo Objetivou-se mensurar o desempenho zootécnico e a qualidade de ovos de codornas japonesas alojadas sob diferentes densidades e alimentadas com rações contendo parede celular de levedura (PCL). Foram utilizadas 576 codornas japonesas (Coturnix japonica) com 43 semanas de idade e 76% de postura, com peso inicial de 158,50 ± 5,41 g distribuídas em delineamento inteiramente ao acaso em esquema fatorial 3 × 2 (três níveis de PCL: 0; 500 e 750 g.ton−1 e duas densidades de alojamento: 81,5 e 92,4 cm2/ave), com seis repetições de 17 e 15 codornas por unidade experimental, respectivamente. Foram avaliados: consumo de ração, produção de ovos/ave/dia, produção de ovos/ave alojada, produção de ovos comercializáveis, massa de ovos, conversão alimentar por dúzia e por massa de ovos e viabilidade das aves; peso do ovo, peso específico, porcentagem de gema, de albúmen e de casca e espessura da casca. Não houve interação entre os níveis de inclusão de PCL e densidade de alojamento para os parâmetros avaliados, exceto para peso do ovo. Codornas alojadas em gaiolas com 92,4 cm2/ave alimentadas com 500 g.ton−1 de PCL apresentaram maior peso do ovo. A espessura de casca foi influenciada de forma independente pela densidade de alojamento, a menor densidade (92,4 cm|2/ave) promoveu maior espessura de casca. A inclusão de 500 g.ton−1 de PCL na ração de codornas japonesas alojadas sob densidade de 92,4 cm2/ave melhora o peso dos ovos e a espessura da casca.

This Scientific Opinion concerns the welfare of Domestic ducks (Anas platyrhynchos domesticus), Muscovy ducks (Cairina moschata domesticus) and their hybrids (Mule ducks), Domestic geese (Anser anser f. domesticus) and Japanese quail (Coturnix japonica) in relation to the rearing of breeders, birds for meat, Muscovy and Mule ducks and Domestic geese for foie gras and layer Japanese quail for egg production. The most common husbandry systems (HSs) in the European Union are described for each animal species and category. The following welfare consequences are described and assessed for each species: restriction of movement, injuries (bone lesions including fractures and dislocations, soft tissue lesions and integument damage and locomotory disorders including lameness), group stress, inability to perform comfort behaviour, inability to perform exploratory or foraging behaviour and inability to express maternal behaviour (related to prelaying and nesting behaviours). Animal-based measures relevant for the assessment of these welfare consequences were identified and described. The relevant hazards leading to the welfare consequences in the different HSs were identified. Specific factors such as space allowance (including minimum enclosure area and height) per bird, group size, floor quality, characteristics of nesting facilities and enrichment provided (including access to water to fulfil biological needs) were assessed in relation to the welfare consequences and, recommendations on how to prevent the welfare consequences were provided in a quantitative or qualitative way.
