1. Descriptive Anatomy of Hepatic and Portal Veins with Special Reference to Biliary Duct System in Broiler Chickens (Gallus gallus domesticus): A Recent Illustration
ABSTRACT Chickens have a great participation in meat and egg production. The anatomical scientific data of poultry is important to support the recent researches either for illustrations in academic studies or clinically in diagnosis and treatment of some poultry nutritional diseases. The current investigation was performed on twenty broiler chickens of both

2. Presence of roosters in an alternative egg production system aiming at animal welfare
ABSTRACT The objective of this study was to evaluate the effect of the presence of roosters on welfare and egg production of laying hens reared in an alternative system. Two breeding systems were established: barn 1 - laying hens reared without roosters (4500 birds); and barn 2 - laying hens reared with roosters (4500 layers and 250 roosters). In the poultry

3. Influence of artificial lighting on the performance and egg quality of commercial layers: a review
In Brazil, the egg production chain produces fresh eggs for the consumer market and for processing. Layers are housed in battery cage systems. Rearing and development farms are separate from egg-production farms. Considering the recent advance of Brazilian chicken egg production, scientific knowledge on management practices are required to disseminate and to

5. Microbiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste an
