Reproductive qualities, exterior features and the quality of the pery of obroshinsky gray geese at their dissolution «inside»

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.
