Synthetic pigments for Japanese quail fed diets with sorghum

ABSTRACT 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 pigment...

description ABSTRACT 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

A fim de substituí-lo, vários ingredientes foram testados. Nesse sentido, destaca-se o sorgo, pois apresenta perfil bromatológico semelhante ao do milho. No entanto, por ser deficiente em carotenoides, sua inclusão na ração reduz a pigmentação da gema do ovo, o que pode ser corrigido por meio da adição de pigmentos sintéticos. Objetivou-se, com este estudo, avaliar o desempenho zootécnico e a qualidade dos ovos de codornas japonesas (Coturnix japonica) suplementadas com os pigmentantes sintéticos vermelho (cantaxantina) e amarelo (apoéster 10%). Foram utilizadas 150 codornas japonesas com 70 dias de idade, distribuídas de acordo com a ração experimental (R1: ração referência à base de milho; R2: ração à base de sorgo (RS); R3: RS + amarelo; R4: RS + amarelo + vermelho; R5: RS + vermelho), com seis repetições e cinco aves por unidade experimental, durante 28 dias. Foram avaliadas as características de desempenho, qualidade dos ovos, cor da gema e custo das rações. Equações de regressão dos efeitos da cor em função dos períodos foram estimadas, e as médias de tratamento foram comparadas pelo teste de Tukey com 0,05 de probabilidade. Não houve efeito significativo (P&gt;0,05) dos aditivos sobre as características produtivas das codornas. Entretanto, a adição de pigmentantes sintéticos melhorou significativamente o perfil cromático das gemas dos ovos de codornas (P&lt;0,05). A inclusão de pigmentantes sintéticos melhora a cor das gemas, porém deve ser avaliada de acordo com as exigências de mercado.</description><identifier>ISSN: 0102-0935</identifier><identifier>ISSN: 1678-4162</identifier><identifier>EISSN: 0102-0935</identifier><identifier>DOI: 10.1590/1678-4162-8167</identifier><language>eng</language><publisher>Universidade Federal de Minas Gerais, Escola de Veterinária</publisher><subject>análise cromática ; cantaxantina ; cor da gema ; VETERINARY SCIENCES</subject><ispartof>Arquivo brasileiro de medicina veterinária e zootecnia, 2016-08, Vol.68 (4), p.1007-1014</ispartof><rights>This work is licensed under a Creative Commons Attribution 4.0 International License.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c384t-7f0a8124a92899c2e45799e0fc2fd441bce9a395c1d7a3c3d4ba9c9a66a132da3</citedby><cites>FETCH-LOGICAL-c384t-7f0a8124a92899c2e45799e0fc2fd441bce9a395c1d7a3c3d4ba9c9a66a132da3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,780,784,885,24150,27924,27925</link.rule.ids></links><search><creatorcontrib>Moura, A.M.A.</creatorcontrib><creatorcontrib>Melo, T.V.</creatorcontrib><creatorcontrib>Miranda, D.J.A.</creatorcontrib><title>Synthetic pigments for Japanese quail fed diets with sorghum</title><title>Arquivo brasileiro de medicina veterinária e zootecnia</title><addtitle>Arq.
