Meat quality of obroshyno grey geese while their cultivation
Journal Title: Ukrainian Journal of Veterinary and Agricultural Sciences - Year 2018, Vol 1, Issue 2
Abstract
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 eviscer-ated 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 gen-eral 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.
