The objective of this study was to determine the best granulometry of maize in rations for Creole ducks (Cairina moschata dosmesticus) in different confinement densities, besides the presumptive identification of enterobacteria of the gastrointestinal tract (GIT) of birds. Thus, an experiment was conducted in the poultry sector of the Faculty of Agrarian Sciences of the Federal University of Amazonas and the Laboratory of Bioactive Principles of Microbial Origin (FCA / UFAM). 240 ducks were used in the experiment. The design was completely randomized in a factorial scheme (2x2), being: density (2 and 3 birds / m2) and corn grain size (6 and 8 mm), with four replications per treatment. With one day of life, 16 birds were slaughtered for cervical dislocation to collect contents of the gastrointestinal tract and GI measurement, repeating the analyzes at 35, 70 and 90 days, and the same were repeated by birds of the mirror. The birds were evaluated weekly to determine the performance of animals and at 90 days, 32 birds were slaughtered to determine the carcass yield, cuts and viscera. Data were submitted to analysis of variance and averages compared by the Tukey test at 5%, by the SAS statistical program. The microbiological analysis was expressed in frequency of occurrence. At 90 days, birds housed in the highest density had better performance (p <0.01), for particle size there was no difference (p> 0.05) in weight gain. In the carcass yield, there was difference in slaughter weight (p <0.01), carcass yield and abdominal fat (p <0.05), in relation to the densities. There were significant differences (p <0.05) in the corn grain size of the rations for slaughter weight, carcass yield and abdominal fat, with a higher weight result when slaughtering birds fed with rations containing less corn grain size (6mm) which was also observed in the commercial viscera, chest, thigh, back and biometries of the chest and leg, thus obtaining the best results. The total number of bacteria isolated was 586, comprising all breeding phases. Ten species belonging to seven genera were identified. Creole ducks raised in the density of 3 birds / m2 and fed with lower corn particle size in the feed (6 mm) showed better performance. E. coli strains normally make up the normal microbiota in the gut of birds, however, birds with symptoms of bacterial infections were not observed.

O objetivo desse estudo foi determinar atrav??s de dados de desempenho zoot??cnico a melhor granulometria do milho nas ra????es para patos crioulos (Cairina moschata dosmesticus) em diferentes densidades de confinamento, al??m da identifica????o presuntiva de enterobact??rias do trato gastrointestinal (TGI) das aves. Assim, foi realizado experimento conduzido no Setor de Avicultura da Faculdade de Ci??ncias Agr??rias da Universidade Federal do Amazonas e no Laborat??rio de Princ??pios Bioativos de Origem Microbiana, ambos da (FCA/UFAM). Utilizou-se 240 patos no experimento. O delineamento foi inteiramente casualizado em esquema fatorial (2x2), sendo: densidade (2 e 3 aves/m2) e granulometria do milho (6 e 8 mm), com quatro repeti????es por tratamento. Com um dia de vida 16 aves foram abatidas por deslocamento cervical para coleta de conte??do do trato gastrointestinal e mensura????o do TGI, repetindo-se as an??lises aos 35, 70 e 90 dias, sendo as mesmas repostas por aves do espelho. Semanalmente as aves foram avaliadas para determina????o do desempenho zoot??cnico e, aos 90 dias, 32 aves foram abatidas para determina????o do rendimento de carca??a, cortes e v??sceras. Dados foram submetidos ?? an??lise de vari??ncia e m??dias comparadas pelo teste de Tukey a 5%, pelo programa estat??stico SAS. A an??lise microbiol??gica foi expressa em frequ??ncia de ocorr??ncia. Aos 90 dias aves alojadas na maior densidade apresentaram melhor efici??ncia de desempenho (p<0,01), para granulometria n??o houve diferen??a (p>0,05) no ganho de peso. No rendimento de carca??a, houve diferen??a no peso ao abate (p<0,01), rendimento de carca??a e gordura abdominal (p<0,05), em rela????o ??s densidades. Para ??s granulometrias do milho nas ra????es, houve diferen??a significativa (p<0,05) para peso ao abate, rendimento de carca??a e gordura abdominal, com maior resultado de peso ao abate aves alimentadas com ra????es contendo menor granulometria do milho (6 mm), o que se observou tamb??m nas v??sceras comerciais, peito, coxa, dorso e biometrias do peito e perna, portanto obtendo os melhores resultados. O total de bact??rias isoladas foi de 586, compreendendo todas as fases de cria????o. Dez esp??cies pertencentes a sete g??neros foram identificadas. Patos crioulos criados na densidade de 3 aves/m2 e alimentados com menor granulometria de milho na ra????o (6 mm) apresentaram melhor desempenho. Cepas de Escherichia coli normalmente comp??em a microbiota normal do intestino de aves, entretanto, n??o foi observado aves com sintomas de infec????es causadas por bact??rias.

Nenhuma dificuldade.
