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.

In the experiments, 160 female birds from populations WG and GG, and 96 birds from population GL were tested up to the 6th production month. The main egg quality traits were controlled. The highest average egg weight was registered in WG group and the lowest in GL group, 14.04±0.32 g and 12.79±0.29 g respectively (p<0.05). The highest average Shape index was observed in group GG (78.31±0.53%), vs the lowest in WG quails (77.55±0.62%). Albumen proportion is almost 2/3 of egg mass, with average values from 57.14% in group WG tо 59.90% in group GG. Yolk proportion was about 30%, with smaller differences between the groups. The shell share from all tested groups comprised between 10.95 and 12.58% of egg weight. Average shell thickness was the greatest in eggs of WG quails (223.53±5.52 μm), and the lowest – in GG quails (216.91±6.83 μm). Egg quality traits were typical for the meat productive type of Japan quails.
The main objective of the current study is to reveal the contribution of intelligent transport systems to the improving of transport services quality and social conditions of living in the urban areas. The provisions of the laws, regulations, ordinances and other legal documents required for this study are analyzed in the paper.
The European Higher Education Area-EHEA is established on the principles and values, indicated in the Bologna declaration from 1999. During the annual conferences of ministers of higher education at countries from EHEA in the next years (Prague, Bergen, London, Leuven, Budapest, and Bucharest) these principles and values are developed and approved. One of these values is the quality of education. The highly compatible educational environment could provide such quality of education through which students acquire knowledge, skills, and competencies, necessary for the labor market. The aforementioned defines the relevance of the scientific problems addressed to the quality of higher education. The problem for quality has many aspects. One of them is at most significant: the quality of education science. It has to solve many tasks, addressed to the quality concept, quality measurement; choice of quality criteria and indicators (according to methods of mathematical taxonomy, multi-factor and cluster analysis, multidimensional scaling), quality verification and etc. Today, the dynamic development of the IT sector and the social trend raise new problems for higher education. Higher schools are related to both the market where quality educational services are provided and the labor market. The students are the consumers of educational services, while employers are the main consumers in the labor market. With the benchmarking approach, higher schools can define clear objectives for their development, based on the
