Abstract
The aim of our research was to increase the productive and reproductive qualities of geese breeders by crossing the white Hungarian and Kuban rocks. To achieve this aim, we should solve the following problems: to study the economically advantageous features of geese flocks of different genotypes and to calculate the cost-effectiveness of the research results. Materials and methods. The experiments were carried out in the Limited company “Bashkirskaya ptitsa” of Blagovar district of Bashkortostan in 2009-2012 by geese flocks of white Hungarian, Kuban breeds and their crosses. To study the productive and reproductive qualities of geese flocks we formed four groups of 64 head of adult geese of first year at the rate of 3 to 1 gander goose. The first group was equipped with Hungarian white goose breeds, the second - the Kuban , the third - a cross between those, obtained by crossing the white Hungarian geese ganders with Kuban, and the fourth - a cross between the Kuban gander and white Hungarian geese. The research was carried out for 150 days. The process parameters and feeding of geese corresponded to VNITIP recommendations. According to the research, we found that the geese of III trial group (♂Hungarian × ♀ Kuban) outnumbered white peers of Hungarian breed and other groups in egg production by 9.6 and 2.2%, respectively, with 3.9% yielding Kuban. The highest content of carotinoids, vitamin A and B2 were found in the eggs of hybrid geese of III group, which amounted to, respectively, 16.05 mkg/g, 9.31 and 8.73 mkg/g. The highest number of conditional geese of first category had also cross-bred geese of third experimental group (♂Hungarian × ♀ Kuban) - 1,447 heads or 85.7%, which is 4.3, 5.9 and 2.2 % had more than a white Hungarian, Kuban breeds of geese and other crossbred groups. Output. Thus, due to the high egg production, the quality of hatching eggs and day-old chicks, the breeding of hybrid geese, obtained in crosses with a white Hungarian geese with Kuban rocks, yielded additional revenue of 119,751.7 rubles and increase profitability by 11.91% , compared with the parental forms Kuban breed geese.
