The process of cultivating obroshyno gray geese improved their meat qualities. In particular, we determined by our researches that, based on the indicators of live weight, the males of the II group (4726 g) prevailed geese of the I and II groups (1.02%), while females of the ІІ group (4153 g) prevailed all groups by 4.19%. The weight of non-eviscerated males of the II group was 4116 g, which is 3.78% higher than that of males of the group I, while females of the group ІІ (3461 g) surpassed other geese by this indicator by 5.10%. The weight of eviscerated of carcasses of males of the II group was 3211 g, which is 3.5% higher than that of males of group I, while females of the second group (2738 g) surpassed others by 6.6%. The outcome of edible parts in the young geese of experimental groups was quite high, but the highest was the young in the second group. In males of the second group, this inicator was 61.5%, and females – 58.9%. The weight of the chilled carcasses of males of the II group was 3120 g, which was 3.93% higher than that of the males of the group I, while the females of the second group (2691 g) surpassed others by 7.04%. The weight of the skin with subcutaneous fat in males of the second group was 706 g, which is 3.67% higher than that of male of the group I (681 g), while females of group II (632 g) surpassed others by 4.64%. The mass of internal fat in males of the ІІ group was 111 g, which is 15.62% higher than that of male of the I group (95 g), while females of ІІ group (72 g) exceeded others by 12.5%. The weight of the muscles in the males of the second group was 1695 g, which is 8.58% higher than that of the male of the group I (1561 g), and the females of the second group (1399 g) surpassed others by this indicator – by 7.6%. The obtained data indicate that the most intense accumulation of dry matter in the chest muscles up to 9 weeks of age occurs in geese of the II group. A similar situation is observed in the femoral muscles. At 9 weeks of age, the males of the second group had 29.74% of the dry matter in the breast muscle of the crude mass, females – 27.35% of the crude mass, and in males of the I group – 27.74%, of females – 27.30%. The same regularity in the content of dry matter is noted in the femoral muscle. The accumulation of protein in the studied muscles of geese, as the main indicator of meat quality, was in accordance with the general laws. The highest rate was in the thoracic and femoral muscles of males and females of the II group. The highest level of total nitrogen content in the muscles was found in males of the second group. In experimental geese, the accumulation of protein nitrogen in the chest muscle is higher than in the muscles of the legs. This indicator is higher in males than females. According to the content of albuminous nitrogen in the chest muscle, the highest rate was observed in males II group (3425 mg%). Non-protein nitrogen in the chest muscles and leg muscles increased to 9 weeks of age.

The research work provided a solution to the problem of preserving the gene pool of Obroshyn gray (OS) and Obroshyn white (OB) geese, which will improve and enhance the valuable qualities of the original flock of geese, gain the desired economic characteristics and thus ensure the competitiveness of the industry in modern conditions. The research was conducted in the laboratory of small livestock ISGKR NAAS and on the basis of SE DG "Miklashiv". The main method of breeding is the selection and selection of individuals with high productive qualities in order to obtain the same type of bird that would meet the planned performance parameters. Selection work was carried out by individual mass selection, aimed at consolidating the standard for each breed group of traits. Before the beginning of the breeding period, males and females of both groups were individually assessed by the exterior, typical plumage, live weight. It was found that both Obroshyn gray and Obroshyn white geese were well selected for productive characteristics and showed high fattening and meat qualities. All birds are well adapted to the natural conditions of the western region. Body sex measurements (chest circumference, torso length, keel, and metatarsus) were higher in males of the Obroshyn gray breed group of geese. Males at different ages had higher rates than females. Obroshyn gray geese (group I) outperformed their peers from group II in terms of meat qualities, the weight of uncorked and gutted carcass, and yield of edible parts. The pre-slaughter live weight of carcasses of males of group I (OS) was 4722 g and prevailed over peers of group II (OB) by 2.94%, and the live weight of females was 4149 g and was higher by 4.19%. It was found that the difference in the number of erythrocytes in males and females was insignificant and almost does not change with age, and hemoglobin on the contrary - increases with age. Males in all study periods had higher serum total protein compared to females. The lowest rate was in males and females аt 4 weeks of age, however, there was no statistically significant difference between the groups in the number of erythrocytes, hemoglobin, and total protein content.

An slaughter, morphological and chemical characteristics of meat obroshynskyh young gray geese, geese crossed with a large gray rock. The average live weight of geese to the top of oviposition was – obroshyno gray, goose – 6.10 kg, geese – 7.00 kg, and Sun OG X: GG goose – 6.15 kg, geese – 7.32 kg. In absolute figures ante carcass live weight of males II (4725 g) prevailed peer group and to 2.94%, and female second group (4152 g) prevailed peers on this indicator at 4.19%. The weight of carcasses of male nepatranoyi second group was at 3.78% larger than males and groups, and group II females predominated peers on this indicator at 5.10%. The weight of carcasses of male patranoyi second group was 3.5% larger than males and groups, and group II females predominated peers on this indicator by 6.6%. Exit edible parts of young research groups was quite high, but this figure was highest in young second group. In the second group of males the figure was 61.5% and females – 58.9%. The mass of chilled carcasses of male second group was at 3.96% larger than males and groups, and group II females predominated peers on this indicator at 7.08%. Weight skin with subcutaneous fat in males Group II at 3.67% higher than the males and females of a second group of peers prevailed on this indicator at 4.64%. The mass of muscles in the male group II at 8.58% larger than the males and females of a second group of peers prevailed on this indicator – by 7.62%. Conducted studies found that productivity was higher in young animals obtained by crossing obroshynskyh gray females with males of a large gray rock.
