| O estudo foi realizado com o objetivo de avaliar o efeito da suplementação de Arginina (Arg) sobre a resposta imune humoral e o desenvolvimento dos órgãos linfoides de frangos de corte imunizados contra a Doença de Gumboro. Foram utilizados 640 pintos de corte, distribuídos aleatoriamente em um delineamento inteiramente casualizado com quatro tratamentos (1. Controle, 2. Imunização, 3. Imunização + suplementação de L-Arg e 4. Suplementação de L-Arg.) e oito repetições de 20 aves cada. As aves dos tratamentos 3 e 4 foram imunizadas no 16° dia, contra a Doença de Gumboro (cepa intermediária plus). Amostras de soro das aves com 14, 21, 28 e 35 dias de idade foram analisadas por ELISA para detecção de título de anticorpos contra a Doença de Gumboro e... |

| ABSTRACT The current study was conducted to examine the effects of an herbal compound, a probiotic and an antibiotic growth promoter (AGP) on the performance, intestinal bacterial population, antibody titers, and morphology of the jejunum and ileum of broilers. A number of 240 male Ross 308 broilers were distributed into four treatments, with five replicates of 12 bird each. The experimental period was 42 days. Treatments includes: 1) basal diet; 2) basal diet supplemented with an AGP (phospho-flavomycin at 450 mg/kg of diet); 3) basal diet supplemented with a Lactobacillus-containing probiotic (250 mg/kg of diet); and 4) basal diet supplemented with an herbal compound (containing thyme, oregano, chamomile, and peppermint essential oils at 1 g/kg of diet).... |

| ABSTRACT The aim of this study was to evaluate the effects of in-ovo vaccination on different incubation days of broiler embryos derived from young and old breeders on incubation indexes, vaccine response, and broiler performance. A number of 20,160 fertile eggs was distributed according to a completely randomized design in a 4 x 2 factorial arrangement (in-ovo vaccination on 16, 17, 18, or 19 days of incubation, and breeders of 31 or 52 weeks of age), totaling eight treatments with 15 replicates of 168 eggs each. Vaccination procedures and vaccines (strains and doses) were those routinely applied in commercial hatcheries. After hatch, 960 male chicks were housed and distributed according to the same experimental design previously applied in the hatchery.... |
