The aim of the study was to evaluate egg production in three heavy Japanese quail populations created and reared in the Poultry Breeding Unit of the Trakia University – Bulgaria, marked as WG, GG and GL. In the experiments, 160 female birds from populations WG and GG, and 96 female birds from population GL were tested up to the 6th production month. The main egg production traits were controlled. The highest egg production for the period was demonstrated in group GL (79.84±4.46%), followed by group GG (76.33±3.40%) and group WG (72.11±4.16%). Quails from the WG group were outlined with least efficient feed conversion per egg (74.49±1.21 g feed), while those from the GL group: with the most efficient one – 64.93±1.41 g (p<0.01). The highest average egg weight in descending order was observed in the WG group (14.04±0.32 g), GG group (13.65±0.27 g) and GL group (12.79±0.29 g). The Japanese quail populations created and maintained at the Trakia University showed a potentially good egg production for the production type they belonged to, which makes them attractive for use in interline hybridisation schedules, including for production of autosexing stock layers.

Body Weights

Egg production-type pullets were fed either corn–soybean meal, wheat–soybean meal, or corn–soy rations containing 15 or 30% of wheat bran or shorts. All diets were fed both in the form of mash and as steamed crumbles. Steam treatment of the corn–soy diet resulted in egg production that was poorer than with a similar diet fed in mash form, and also inferior to that with most of the other experimental rations. In an overall comparison, the mash diets resulted in significantly more eggs per bird than did the steam-crumbled rations.In general, birds fed crumbled rations consumed more feed and gained more weight than those fed mash rations. The increase in energy consumption with the crumbled feed was apparently in excess of requirements and was consequently laid down as fat in the body, as suggested by the increased body weights. It seems evident that the energy content of diets for caged layers should be lower when crumbled feed is provided than when mash is used.The wheat-shorts diets fed in the form of mash resulted in higher production than did the bran diets fed in mash form. However, when these diets were fed as steamed crumbles there was no signficant difference between the shorts and bran rations.
