It was found that the average live weight of geese at the beginning of the oviposition was (OS – 3% X OS – 3%): goose – 6.10 kg, goose – 7.30 kg, and (OS – 5% X OS – 5♂): goose – 6,30 kg, goose – 7,37 kg. The average weight of OS–3 goose was 39.5 eggs per head, and OS–5 – 41.4 eggs. At the same time, the average weight of eggs in the 1st group was 154.3 g, and in II – 158.5 g. The indexes of the forms in the I group consisted of: the length of the egg – 84.4 mm, the width – 55.4 mm, the index of form 65.6 in the second group respectively – 84.3 mm; 56.3 mm; 66.7 mm. The study of the incubation qualities of eggs indicates that the higher fertility was in the goose of the second group and amounted to 85.3%, which is 0.9% more compared with the I group. It is known that the yield of caterpillars is dependent on fertility and in the 1st group this indicator was 71.8%, which is 4.3% less than in the second group (76.1%). At 9 weeks of age, males of the II group surpassed their peers from the 1st group by chest covering 1.79%., With a body length of 2.08%, and a kilo length of 7.14%. The same tendency was observed in the shoots of the shin and plyusny, so the males of group ІІ in the first indicator dominated the male and group I by 8,19%; in the second indicator males of the II group dominated the males of the I group by 6.68%. At 9 weeks of age, females of group ІІ grouped over their breasts over their peers from the 1st group by 2.40%, with the body length by 3.21%., With the length of the keel – by 2.34%. Length of the leg and shoulders in the females of the 2nd group were the largest and dominated by females and groups I by the first indicator at 5.26%; in the second indicator, females of the second group dominated the females of the I group by 1.08%. Males at all investigated periods had higher levels of total protein in serum than females. It was found that males at all investigated periods had higher levels of total protein in serum than females. Performance indicators of Ohorin gray geese (Group I) consisted of: carcass weight – 39.5 pc. on the head; the weight of eggs – 154.3 g; fertility – 84.4%; deductibility – 71.8%; the live weight of geese in the 9-week-old age is 4.52 kg males and 3.84 kg females; preservation – 90.7%. Obroshinsky gray goose (group II) are characterized by the highest indexes in relation to the first group: for fertility by 4.8%, fertility by 0.9%, output by 4.9%, live weight of geese at 9 weeks of age (males) – 1.99%, (females) by 0.52%, preservation – 2.90%, egg mass – 2.64%. The highest feather-down raw material was obtained at the age of 18 in geese I group. The basic indices of blood of the examined geese were within the acceptable limits of the norm.

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 purpose. Perfecting pedigree and productive qualities of Obroshin grey and white gooses at growing «in it». That has allowed saving valuable qualities of initial livestock. Methods. Selectionpedigree work was carried out with the use of instrumental methods and the newest recommendations concerning application of physiological and-biochemical markers of assessment of economically beneficial attributes, supervisory control of exterior indexes and methods of analysis of variance. Results. Experimentally is fixed that average egg production of gooses in I group made 41 pieces of eggs for a head, II -40,5, III -38,6, IV group -38,1 pieces of eggs. Average mass of an egg in I group made 160,1 g, ІІ -162,4, III -153,2, IV -159,1 g. Breeding fficiency of eggs was above at gooses of I group -84,3%. The maximum hatchability had gooses of II group -76,5%. Preservation of young birds in I group was the best and made 92%. Conclusions. By results of slaughter it is determined that mixed Obroshin white gooses predominated above coevals by preslaughter alive mass, mass of viscerated carcass and edible parts of a body.Key words: gooses, egg production, breeding efficiency, hatchability, preservation of young birds, dressing percentage.Nowadays poultry farming is the largest supplier of valuable animal protein, the role of which is very important in human nutrition [4,10]. The development of poultry farming depends largely on selection work aimed at improving productive and breeding properties, creating new breeds, lines and crosses of all kinds of poultry, as well as full and balanced feeding and implementation of new hightech technology.The meat of young geese is high-calorie and delicious. A delicacy is the goose liver (foie gras), which is highly valued at the world market [1].Even for pasture cultivation, the live weight of caterpillars already reaches 3.5-4 kg in the age of 8-10 weeks, and 4-4.5 kg in the case of intensive feeding, with the consumption of concentrated feed up to 3 kg per 1 kg of growth. The 8 -9-week old geese contain a 17 -18% protein, fat -21 -22%. The energy value of the geese meat is determined from the calculation: 1 kg of edible part of the goose carcass contains 13. [5,7].The purpose of the research is to improve the tribal and productive properties of the prehistoric gray and white geese for breeding "in itself", which will enable to preserve the valuable properties of the initial population and, thus, to ensure their competitiveness in modern conditions. These studies were conducted through the selection of individuals with high productive properties for the purpose of obtaining the same type of poultry, which would correspond to the planned performance parameters under improved conditions of feeding and growing [8,10].

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.

Ключові слова: гуси, інкубаційні якості, несучість, заплідненість, виводимість, динаміка живої маси. Вступ. Для ефективного ведення галузі птахівництва вирішальне значення має використання спеціалізованих порід і кросів сільськогосподарської птиці. Зростання продуктивності на 35-40 % зумовлене досягненнями у галузі генетики, селекції та розведення. Використання сучасних порід і кросів, які мають високий потенціал продуктивності, дасть можливість виробникам птахівничої продукції за оптимальних умов утримання, повноцінної годівлі та належного ветеринарно-санітарного забезпечення досягти високих результатів господарювання. Високий рівень ведення племінної роботи є важливою передумовою ресурсоощадної технології, що визначає витрати кормів на одиницю продукції, її якість та прибуток [7, 12, 17, 31]. Гусівництво є перспективною галуззю птахівництва у виробництві м'яса птиці. За швидкістю росту, здатністю перетравлювати значну кількість зелених та соковитих кормів з високим вмістом клітковини, високою життєздатністю та за іншими господарсько корисними ознаками гуси мають ряд переваг порівняно з
