Resumo: | Betaine is a derivative of the amino acid glycine, found in most organisms. Due to its function as a donor of methyl groups and low cost, has been used as a substitute for methionine in broilers nutrition. This study aimed to evaluate the effect of betaine supplementation in partial substitution of methionine + cystine requirement on productive performance, carcass yield and economic viability of betaine inclusion in the feed of European quails. A total of 920 European quails were used from 1 to 42 days of age. Birds were distributed in a completely randomized design of four treatments with 10 repetitions and 23 birds per experimental unit. Each treatment consisted of an experimental feed. In treatment 1, birds received a control feed, which was based in corn and soybean meal without any betaine supplementation and fulfilling nutritional requirements. In treatment 2, feed was formulated with a 5% reduction in methionine + cystine requirement values without betaine supplementation. In treatment 3, birds were fed with 5% reduction in methionine + cystine requirement values and supplemented with betaine. Treatment 4 consisted of a feed with 10% reduction in methionine + cystine requirement values with betaine supplementation. Analyses of variables revealed a significant effect (P<0.05) of treatments on weight gain of quails from 1 to 21 days of age, all treatments being superior to the control treatment. At 42 days of age, it was observed that all treatments were superior to the control treatment for slaughter weight and eviscerated weight. The weight of thigh + drumstick presented a satisfactory result in the treatments with betaine use, however, did not they differ from the treatment with 5% reduction of methionine + cystine without betaine supplementation. Treatments did not influence feed intake, weight gain and feed conversion in the period of 22 to 42 days of age. The treatments did not significantly influence (P> 0.05) the weight of lymphoid organs, liver and blood parameters of quails at 42 days of age. However, economic analysis of treatments demonstrated a reduction in price per kilogram of feed and better economic efficiency with betaine supplemented diets. Betaine can substitute up to 10% as methionine + cystine requirements of European quails, without compromising the productive performance, carcass characteristics, physical quality of the meat and the immune response of the birds |

Betaine can substitute up to 10% as methionine + cystine requirements of European quails, without compromising the productive performance, carcass characteristics, physical quality of the meat and the immune response of the birdsA betaína é um derivado do aminoácido glicina, encontrado na maioria dos organismos. Devido sua função como doador de grupos metil e seu baixo custo, tem sido utilizada como substituto parcial a metionina em rações de frangos de corte. Assim, objetivou-se avaliar o efeito da suplementação de betaína em substituição parcial às exigências de metionina+cistina, sobre o desempenho produtivo, rendimento de carcaça e resposta imune de codornas europeias, bem como a viabilidade econômica da inclusão da betaína nas rações. Foram utilizadas 920 codornas europeias, no período de 1 a 42 dias de idade, distribuídas em delineamento inteiramente casualizado, com quatro tratamentos, dez repetições e 23 aves por unidade experimental. Os tratamentos consistiram de quatro rações experimentais, sendo o tratamento 1, uma ração controle a base de milho e farelo de soja sem suplementação de betaína; tratamento 2, ração com redução de 5% da exigência de metionina+cistina sem suplementação de betaína; tratamento 3, ração com redução de 5% da exigência de metionina+cistina com suplementação de betaína e tratamento 4, ração com redução de 10% da exigência de metionina+cistina com suplementação de betaína. Para as variáveis estudadas observou-se efeito significativo (P<0,05) dos tratamentos sobre o ganho de peso das codornas no período de 1 a 21 dias de idade, sendo todos os tratamentos superiores ao tratamento controle. Aos 42 dias de idade, observou-se que todos os tratamentos foram superiores ao tratamento controle para peso ao abate e peso eviscerado. O peso de coxa+sobrecoxa apresentou resultado satisfatório nos tratamentos com utilização de betaína, porém, não diferiram do tratamento com redução de 5% de metionina + cistina sem suplementação de betaína. Não houve efeito dos diferentes tratamentos para consumo de ração, ganho de peso e conversão alimentar no período de 22 a 42 dias de idade. Da mesma forma, os tratamentos não influenciaram (P>0,05) o peso dos órgãos linfoides, fígado e parâmetros sanguíneos das codornas aos 42 dias de idade. No entanto, a análise econômica das rações mostrou uma redução no preço por quilo de ração e melhor eficiência econômica com a suplementação de betaína. Logo, a betaína pode substituir até 10% as exigências de metionina+cistina de codornas europeias, sem comprometer o desempenho produtivo, características da carcaça, qualidade física da carne e resposta imune das avesCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESUniversidade Federal Rural do Semi-ÁridoBrasilCentro de Ciências Agrárias - CCAUFERSAPrograma de Pós-Graduação em Ciência AnimalAraújo, Marcelle Santana de07806547738http://lattes.cnpq.br/3195264082485232Freitas, Carlos Iberê Alves77442032753http:lattes.cnpq.br/4480397911889351Silva, Jean Berg Alves da02556429461http://lattes.cnpq.br/1849041497210600Costa, Leonardo Lelis de Macedo00991105478http://lattes.cnpq.br/8037376675873363Braga, Juliana Forte Vilarinho02083443162http://lattes.cnpq.br/2929284462670555Queiroz, João Paulo Araújo Fernandes de04970058407http://lattes.cnpq.br/5966379691271313Oliveira, Vanessa Raquel de Morais2019-04-10T14:10:06Z2019-03-132019-04-10T14:10:06Z2018-02-27info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfCitação com autor incluído no texto: Oliveira (2018) Citação com autor não incluído no texto: (OLIVEIRA, 2018)https://repositorio.ufersa.edu.br/handle/prefix/1064porOLIVEIRA, Vanessa Raquel de Morais.
