The research was carried out on a number of 300 meat quails from the brown Jumbo population; sacrifices were made at the age of 42 days, 49 and 56 days separately by sex. Following the research, the average live weight at 42 days was of 290.60 ± 8.38 g / bird head in females and 245.00 ± 7.90 g / head in males, at 49 days it was 326.00 ± 11.41 g / bird in females and 256.80 ± 6.14 g / bird in males, while at 56 days this was 332.80 ± 8.51 g / bird in females and 269.60 ± 4.18 g / head in males, the differences between sexes being very significant. The yield of the eviscerated carcass at 42 days was 70.45 ± 1.46 % in females and 70.98 ± 1.89 % in males, at 49 days it was 67.19 ± 1.02 % in females and 71.14 ± 0.87 % in males, and in 56 days this was 71.56 ± 0.68 % in females and 70.05 ± 0.25 % in males. From the point of view of the evolution of the average daily weight gain during the period 1-56 days, as well as the weight of the carcass and its component parts, conclusions can be drawn regarding the optimal age of slaughter of Jumbo quails. This is of 42 days in case of slaughtering both sexes, 42 or 49 days in case of females slaughtering and 42 days of males. [ABSTRACT FROM AUTHOR] |
