This work presents the results of chemical analysis of breast and thigh muscles in common pheasants fattened until the age of 90 days, and evaluates changes in the quality of pheasant meat between the 40th and 90th day of fattening.
Water content in breast muscles of female pheasants conclusively decreased (P0.05) to 745.41 g/kg on the 90th day of fattening while the dry matter content increased to 254.59 g/kg. A similar trend, i.e. decrease of water content and increase of dry matter level, was observed in males on the 90th day of fattening but the changes were inconclusive. Changes in protein levels (NS) in breast muscles were also inconclusive. The mean protein levels in female pheasants were ca. 229.05 g/kg, in the case of males they ranged from 229.88 g/kg to 245.03 g/kg. The fat content in breast muscles in pheasant poults increased with age. Particularly females exhibited a very conclusive increase in fat content (P0.01) on the 90th day (7.79 g/kg) while in males the fat content increased inconclusively (8.87 g/kg). The levels of ash determined in breast muscles ranged from 12.31 g/kg to 11.62 g/kg and from 12.72 g/kg to 11.72 g/kg in females and males, respectively. This parameter was not significantly affected by the age of young pheasants.
The mean water content in thigh muscles ranged between 730.56 g/kg and 759.91 g/kg in females and between 725.03 g/kg and 753.37 g/kg in males. The changes in water content were related to the changes in dry matter levels. The mean protein levels in thigh muscles of female pheasants decreased to 189.90 g/kg on the 90th day of feeding (P0.05), while in males a highly conclusive decrease to 197.92 g/kg (P0.01) was found. Fat levels in both breast and thigh muscles gradually increased. Thus, fat levels in thigh muscles of females increased from 21.06 g/kg (on the 40th day) to 57.49 g/kg (on the 90th day). In the case of males the fat levels increased from 19.66 g/kg (on the 40th day) to 45.24 g/kg (on the 90th day). Similarly, the mean levels of ash ranged from 12.62 g/kg to 12.66 g/kg in females and from 12.82 g/kg to 12.44 g/kg in males. However, no conclusive differences due to the duration of fattening were found.
