Este trabalho teve como objetivo definir o melhor nível energético na ração para perdizes na fase de reprodução, avaliando consumo de ração, produção e peso médio dos ovos e conversão alimentar. Os tratamentos foram três rações isoprotéicas (15%PB) com níveis de energia de 2650, 2800 e 2950 kcal EM/kg. Foram utilizadas 24 aves em fase de reprodução da espécie Rynchotus rufescens, com 10 meses de idade. O delineamento experimental foi inteiramente casualizado, com 3 tratamentos (níveis de energia) e 4 repetições, com um casal por parcela. Os resultados mostraram que não houve diferença significativa para consumo, mas houve efeito significativo positivo do nível de energia sobre o peso médio e a produção dos ovos. A conversão alimentar para os níveis de 2650... |

This study aimed to evaluate diets supplemented with prebiotic, probiotic and symbiotic as an alternative to antibiotics on the performance and immune response against the virus of Newcastle disease in broiler chickens. 1,400 one-day old male Cobb 500 chicks were raised until 42 days old in a completely randomized design with 2x2+1 factorial scheme with seven replications. The treatments were: diet without supplementation (base diet - BD), BD + prebiotic, BD + probiotic, BD + symbiotic (prebiotic + probiotic), and BD + antibiotic. The parameters evaluated were performance and antibody serum titers against Newcastle disease. No antibiotic effect was observed on performance. The symbiotic provided better results for weight gain and feed:gain ratio until 21... |

ABSTRACT The objective of this study was to investigate the influence of two cleaning and disinfection programs on broiler performance and on the microbiological status of the facilities. This trial was an observational study of comparative character. Two experiments were conducted, with 960 birds each. Both experiments were carried out in a positive-pressure broiler house. Broilers were distributed in pens equipped with a bell drinker and a tube feeder each. In the first experiment, new wood shavings were used as litter material, and in the second, reused wood shavings were used. Two treatments with16 replicates of 30 birds each were evaluated. The regular treatment consisted of dry and wet organic matter removal, followed by washing. The European... |
