Resumo: | The objective of this work was to evaluate the inclusion of sunflower cake (SC) and the addition of enzymes in the ration of lightweight replacement pullets in the growth phase, as well as their effects on the variables feed consumption and conversion, productive performance, sexual maturity, egg quality at the beginning of the laying phase, and economic viability. Five hundred and forty pullets of the Hy-Line W-36 light line were used. The experimental design was completely randomized, in a 2×2+1 factorial arrangement, with two inclusion levels of SC (10 and 20%), with or without the addition of enzymes, and a control treatment. At the end of the growth phase (7 to 17 weeks age), 360 birds were transferred to the laying shed until their thirty-fifth week of age. There was no interaction between SC levels and enzymes, but an isolated effect of rations and enzymes was observed on feed consumption and conversion. There was a decrease in specific egg density and an interaction between the factors for this variable, but without affecting productive performance. The inclusion of up to 20% SC in the rations does not affect bird performance in both evaluated phases; however the use of 20% SC with enzymes is more economically viable. |

Foram utilizadas 540 frangas da linhagem leve Hy-Line W-36. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2×2+1, com dois níveis de inclusão de TG (10 e 20%), com ou sem adição de enzimas, mais um controle. Ao final da fase de crescimento (7 a 17 semanas de idade), 360 aves foram transferidas para o galpão de postura até a trigésima quinta semana de idade. Não houve interação entre os níveis de TG e as enzimas, mas observou-se efeito isolado das rações e das enzimas sobre o consumo e a conversão alimentar. Houve diminuição da densidade específica dos ovos e interação entre os fatores para essa variável, mas sem afetar o desempenho produtivo. A inclusão de até 20% de TG nas rações não afeta o desempenho em ambas as fases avaliadas; no entanto, o uso de 20% de TG com enzimas é mais economicamente viável.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlencar, Amanda Virgínia OliveiraNascimento, Germano Augusto Jerônimo doFreitas, Ednardo RodriguesSouza, Davyd HerickCosta, Monik Kelly de OliveiraRocha, Amanda Karen Santos2019-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26628Pesquisa Agropecuaria Brasileira; V.54, Jan./Dec., 2019: Publicação contínua em volume anual; e00983Pesquisa Agropecuária Brasileira; V.54, Jan./Dec., 2019: Publicação contínua em volume anual; e009831678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26628/14543Direitos autorais 2019 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2019-12-11T14:17:51Zoai:ojs.seer.sct.embrapa.br:article/26628Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2019-12-11T14:17:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
