Previous issue date: 2018 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / O gr?o seco de destilaria com sol?veis (DDGS) ? um coproduto da ind?stria de etanol do milho e pode ser utilizado na alimenta??o animal, como substituto do farelo de soja. Foram realizados dois experimentos com o objetivo de avaliar diferentes n?veis de inclus?o de DDGS de milho na dieta de codornas e galinhas poedeiras, sobre o desempenho, qualidade dos ovos, pigmenta??o da gema e an?lise econ?mica. No experimento 1, foram utilizadas 210 codornas poedeiras (Coturnix japonica) com 23 a 31 semanas de vida, distribu?das em delineamento inteiramente casualizado com cinco tratamentos e seis repeti??es, com sete aves por unidade experimental. No experimento 2, foram 150 galinhas poedeiras (Hisex Brown) com 54 a 62 semanas de vida, distribu?das em delineamento interiramente casualizado com cinco tratamentos e seis repeti??es, com cinco aves por unidade experimental. Os tratamentos utilizados nos dois experimentos foram: ra??o controle; inclus?o de 5% de DDGS; inclus?o de 10% de DDGS; inclus?o de 15% de DDGS e inclus?o de 20% de DDGS. As vari?veis avaliadas foram: consumo de ra??o, convers?o alimentar por d?zia e massa de ovos, produ??o de ovos, peso dos ovos, peso da gema, alb?men, varia??o do peso corporal, viabilidade das aves, gravidade espec?fica, colora??o da gema, componente do ovo e an?lise econ?mica. No experimento 1, para as vari?veis consumo individual, convers?o alimentar por massa de ovos, taxa de postura, gravidade espec?fica e e colora??o da gema pelo leque colorim?trico houve efeito com a inclus?o do DDGS (P<0,05), para as demais vari?veis n?o houve efeito significativo. No experimento 2, para as vari?veis colora??o da gema pelo leque colorim?trico e colorimetro digital (L* e a*) houve efeito linear com a inclus?o do DDGS (P<0,05), para as demais vari?veis n?o foi observada diferen?a significativa. Quanto ? an?lise econ?mica, o DDGS pode ser considerado um alimento alternativo pelo baixo custo (R$). O DDGS de milho tem o potencial pigmentante na gema do ovo, fazendo com que apresente mais amarela sem influenciar o desempenho e a qualidade dos ovos das galinhas e codornas poedeiras, al?m de ser um produto mais econ?mico. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2018. / Dry distillers grain with Solubles (DDGS) is a Coproduct of ethanol corn industry and can be used in animal nutrition, as a substitute for soybean meal. Two experiments were conducted to evaluate different levels of inclusion of DDGS of cornmaize in the diet of laying hens and Japanese quail, about the performance, eggs quality, yolk pigmentation and economic analysis. In experiment 1, 210 were used laying quail (Coturnix japonica) with 23 to 31 weeks of life, distributed in completely randomized design with six treatments and five replicates, with seven quail per experimental unit. In experiment 2, were 150 laying hens (Hisex Brown) with 54 to 62 weeks of life, distributed in entirely randomized design with six treatments and five replicates, with five birds per experimental unit. The treatments used in two experiments were: T1: ration control; T2: inclusion of 5% of DDGS; T3: inclusion of 10% of DDGS; T4:15% inclusion of DDGS; T5: inclusion of 20% of DDGS. The variables evaluated were: feed intake, feed conversion per dozen and mass of eggs, egg production, egg weight, weight variation, viability of birds, gravity specifies, coloring of the yolk, egg component and economic analysis. The data were subjected to analysis by linear and quadratic regression models, the 5% probability. In experiment 1, to the individual consumption and feed conversion ratio by mass of eggs there was quadratic effect with the inclusion of DDGS (P < 0.05), for gravity and egg weight, egg yolk, and gem coloration for range and colorimetric digital colorimeter (b *) effect with the inclusion of DDGS (P < 0.05), for the other variables had no significant difference. In experiment 2, for the variables weight of yolk, albumen and bark, and gem coloration for range and colorimetric digital colorimeter (L *) there was no linear effect with the inclusion of DDGS (P < 0.05), the other variables had no significant difference. As the economic analysis the DDGS can be considered an alternative food for low cost (R$). The DDGS of corn has the potential pigmentante in egg yolk, making present more yellow mainly to higher levels, without affecting the performance and eggs quality of hens and laying quails, as well as being a more economic product.
