Grãos secos de destilaria com solúvel de milho na dieta de galinhas poedeiras

The objective of this study was to evaluate the different levels inclusion of corn DDG in the laying hens diet and its effects on the performance, egg quality, yolk pigmentation and economic analysis. A hundred fifty laying hens (Hisex Brown) were distributed in a completely randomized design with five treatments and six replicates, with five birds per experimental unit. The diet formulations met the nutritional requirements of the chickens, using the following treatments: control diet with the inclusion of 0% of DDG; inclusion of 5%, 10%, 15% and 20% of DDG. There was no effect (P> 0,05) on egg quality and performance parameters, the yolk coloring, by the colorimetric spectrum and digital colorimeter (L and a *); there was an effect with DDG inclusion (P <0,05).  The corn DDG has a coloring potential in the egg yolk, making it appear more yellow, without influencing the performance and egg quality on laying hens, besides being a more economical product.Objetivou-se avaliar diferentes níveis de inclusão de grãos secos de destilaria (DDG) de milho na dieta de galinhas poedeiras e seus efeitos sobre o desempenho, a qualidade dos ovos, a pigmentação da gema, e realizar análise econômica do custo de produção e alimentação. Foram utilizadas galinhas poedeiras (Hisex Brown), distribuídas em delineamento inteiramente casualizado com cinco tratamentos e seis repetições, com cinco aves por unidade experimental. Os tratamentos utilizados foram: ração controle com a inclusão de 0% de DDG; inclusão de 5% de DDG; inclusão de 10% de DDG; inclusão de 15% de DDG e inclusão de 20% de DDG. As variáveis avaliadas foram: consumo de ração, conversão alimentar por dúzia e massa de ovos, produção de ovos, peso dos ovos, variação do peso corporal, viabilidade das aves, gravidade específica, coloração da gema, componente do ovo e custo de produção e de alimentação. Os dados foram submetidos à análise pelos modelos de regressão, a 5% de probabilidade e pelo teste de Dunnett a 5% de probabilidade. Não houve efeito (P>0,05) para os parâmetros de desempenho e qualidade do ovo em nenhum nível de inclusão do DDG. Para a coloração da gema pelo leque colorimétrico e colorímetro digital (L e a*) houve efeito linear crescente com a inclusão do DDG (P<0,05). Quanto à análise econômica, o DDG pode ser considerado um alimento alternativo ao farelo de soja pelo baixo custo. O DDG de milho tem o potencial pigmentante na gema do ovo, fazendo com que se apresente mais amarela, sem influenciar o desempenho e a qualidade dos ovos das galinhas poedeiras, além de ser um produto mais econômico

Distillery dried grains with soluble from corn in diet of laying hens

Corn distillers dried grains with solubles in the feed of broilers and their effects on the performance, carcass yield, and gastrointestinal characteristics

This study has as an objective to determine the effect of different inclusion levels of dried distillery grain with soluble (DDGS) on meat chicken diet to its performance, carcass yield and cuts and gastrointestinal tract biometry. A mixed lot of 700 one-day-old chickens from COOB 500 linage was used, distributed in a completely randomized design with 5 treatments, 7 repetitions and 20 broilers per experimental unit, were 10 was male and 10 female. The studied levels of DDGS were 4; 8; 12 and 16% of inclusion on experimental rations, plus the control treatment (0%). At the 1st and the 42nd days of life, the broilers were weighted, as the remains of ration to obtain variables of performance. For performance it was evaluated weight gain (WG) (g/bird/day), ration consumption (RC) (g/bird/day), feed conversion (FC), medium weight (MW), productive efficiency index (PEI), and viability (V). At 42 days of age 2 broilers from each lot was selected, weighted and identified with medium weight from the experimental unit for slaughtering and evaluation of cuts yield, carcass and gastrointestinal biometry. The evaluated parameters were submitted to variance analyses with 5% of probability using the statistical program SAS. Effects of inclusion of DDGS were estimated through variable analyses via linear regression models and the contrasts by the Dunnett test with 5% of probability. For the variables WG, FC, MW and PEI on the period of 1-42 days of production, it was obtained values of better performance on the level of 7,28%; 10,60%; 12;10% e 12;92% respectively. There was a reduction of carcass weight, of breast and fat of the broilers when using 12 and 16% of DDGCS. Therefore, it has indicated the inclusion of until 11, 02% and 7, 44% on the diet so there is no loss on carcass yield and breast weight, respectively.This study was conducted to determine the effect of different levels of corn distillers dried grains with solubles (DDGS) in the diet of broilers, with regard to the performance, carcass yield, and gastrointestinal characteristics. A mixed lot of 700 one-day-old broilers from the COOB 500 lineage were used. It was distributed in a completely randomized design with five treatments, seven repetitions, and twenty broilers per experimental unit — ten male and ten female. The DDGS levels studied were inclusion of 4%, 8%, 12%, and 16% on experimental diets, plus the control treatment (0%). The period of 1–42 days were considered for performance evaluation. For performance, the following factors were evaluated weight gain (WG) (g/bird/day), ration consumption (RC) (g/bird/day), feed conversion (FC), medium weight (MW), productive efficiency index (PEI), and viability (V). At 42 days of age, two broilers from each lot were selected, weighed, and the ones with medium weight were identified from the experimental unit, for slaughtering and evaluation of cut yield, carcass, and gastrointestinal biometry. The evaluated parameters were submitted to variance analyses with a 5% probability, using the statistical program SAS-2012. The effects of the inclusion of DDGS were estimated through variable analyses via regression models and the contrasts by the Dunnett test, with a 5% probability. In the period of 1–42 days of production, the values of better performance obtained for the variables WG, FC, MW, and PEI were at levels of 7.28%; 10.60%; 12.10%, and 12.92%, respectively. There was a reduction in carcass weight, breast, and fat of the broilers, when using 12% and 16% of DDGS. Therefore, it indicated the inclusion of up to 11.02%, and 7.44% in the diet, so there was no loss on carcass yield and breast weight, respectively
