نویسندگان
چکیده
The work includes partial results, concerning characterization of the order Galliformes birds, genus Coturnix, Coturnix coturnix japonica species, on the teritory of Bihor county. Researches were conducted in three private hennery from both Oradea and Bihor county. Parameters studied refers to the analysis of the incubation process, namely: % clear eggs and % of fertility, % eggs with dead embryos at each cumulated and carried out biological control; % of eclozabilitate; % hatching; dead chickens weight and their fall on quality classes. Following the analysis of the incubation process was calculated a value of 90.7% for fertility and 83.7% for hatching percentage.

Keeping Japanese quail is an economic way for producing egg, because of their early sexual maturity (laying egg after 35 days), high egg production (250–270 eggs per year), resistance to most of poultry disease and great egg production persistency on a high level (approximately 14–18 months) (MURAKAMI and ARIKI, 1998). Japanese quail maturation happens in about 6 weeks of age and mature females...
