Meat and feather and down performance obroshynskyh gray geese II generation, crossed with a big gray breed

Abstract

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.
