ABSTRACT Brazilian poultry production is growing, mainly due to the cost and benefit that chicken meat provides. The importance of free-range chickens and the susceptibility, to which they are exposed, makes it necessary to know about gastrointestinal parasites and the consequences that large infections can cause for them as such as weight loss. The present study aimed to determine the occurrence of gastrointestinal parasites in free-range hens raised in an extensive regime in the municipality of Santa Rita, state of Maranhão, Brazil. The studied population was composed of adult chickens (Gallus gallus domesticus) acquired from slaughterhouses in the region. The gastrointestinal organs of each chicken were separated and subsequently conditioned in flasks... |

Epididymal lithiasis (EL) histopathology is described using light and electronic microscopy in roosters (Gallus gallus domesticus) naturally affected by EL in Minas Gerais, Brazil. The histologic and morphological changes by EL in roosters was performed regarding cellular and subcellular details through light and electron microscopy. Efferent ductules epithelium lysosomal increase in size and numbers, membrane rupture, cellular vacuolation, ciliary loss, basal membrane degeneration, inflammatory reaction with mononuclear infiltrations, edema, epithelial and vascular endothelium losses were described. All industrial and freerange chickens showed EL in varying degrees in the efferent ductules (ED). However, ED altered areas did not correlate with the... |

ABSTRACT Serum samples (n=687) from Gallus gallus domesticus were collected for the investigation of antibodies to avian influenza virus (AIV-A) in the family poultry of the surrounding counties of Santa Maria/RS and the metropolitan region of Belo Horizonte/MG, totaling twenty different counties. Additional samples of seventeen (n=17) free-flying ducks (C. moschata pure or hybrid with Anas platyrhynchos) were collected in Belo Horizonte. The chosen tests for the survey were performed as described by the World Organization for Animal Health (OIE), including agar gel immunodiffusion (AGID) for antibodies to AIV-A nucleoprotein (N) and haemagglutination- inhibition (HI) for antibodies to subtype H1. Out of the 704 serum tests performed by AGID, eight (8/704)... |

A study on the occurrence of epididymal lithiasis (EL) in Gallus gallus domesticus of different breeds and from different geographical regions of Brazil was carried out. Forty breeding roosters were collected in the states Santa Catarina, São Paulo, Minas Gerais, Espírito Santo and Goiás, representing two specific pathogen free Leghorn lines (SPF), one commercial Leghorn layer breeder (Hy-Line) line, two commercial broiler breeder lines (Ross and Cobb), and two backyard chicken flocks. In commercial poultry breeders, EL was observed mainly after 55 weeks of age, and lithus resulted in lower fertility caused by inadequate maturation of spermatozoa and testicular atrophy, which evolved to more severe testicular dysfunction at 100 weeks of age. One hundred... |

Estudou-se em trinta exemplares de Gallus gallus domesticus da linhagem Avian Farms, fêmeas, com idades entre 10 e 12 semanas, a origem, o número e a ordenação dos vasos arteriais da bolsa cloacal, mediante injeção dos sistemas vasculares arteriais das aves com solução aquosa de Neoprene Látex 450 a 50% e posterior dissecação. Os resultados mostraram a participação das artérias bursocloacais direita e esquerda em todos os casos, às quais se associavam as artérias mesentérica caudal e caudal mediana em 13,33% e 3,33% dos casos, respectivamente. O número total de vasos, independentemente da origem, variou de 2 a 5 com maior freqüência de 2 a 3 vasos. |

A hipotermia em aves sob anestesia é freqüentemente observada, causando alterações fisiológicas e metabólicas que podem levar ao óbito. O estudo avaliou dois métodos de manutenção térmica em galinhas submetidas à anestesia inalatória com isofluorano. Foram utilizadas seis galinhas, pesando entre 1 e 1,5kg, com idade aproximada de um ano. Os animais foram autocontrole, submetidos a três grupos: controle (GC), não sendo utilizado nada; alumínio (GA), envoltos por papel alumínio comercial; manta (GM), envoltos por uma manta térmica de dupla face de alumínio. Após jejum prévio de quatro horas, as aves foram submetidas à anestesia inalatória por meio de máscara facial com 4V% de isofluorano e mantidas posteriormente com 2V% do mesmo agente inalatório, em um... |

The subcutaneous acarid parasite Laminosioptes cysticola, the fowl cyst mite, has been found for a number of years in free-range chickens of peri-urban and rural Minas Gerais, forming collagen cysts which may be subsequently calcified after the parasite's death. The role of free-range chickens as hosts and the possible risk of food-borne human allergy, as a result of its consumption in feed, are considered. |
