The effect of season, sex, and portion on the carcass characteristics, pH, color, and proximate composition of Egyptian Goose (Alopochen aegyptiacus) meat.
The carcass yield, physical characteristics, and proximate composition of Egyptian geese (Alopochen aegyptiacus), a southern African gamebird species, have been studied. A total of 69 geese were harvested during 2 seasons: summer (n = 36) and winter (n = 33). This total group of geese consisted of 27 female birds and 42 male birds. Sex alone affected (P ≤ 0.05) the live and carcass weights, and the average muscle weight (g) of each portion was higher for the male fowl. The data does not indicate differences between the meat's physical characteristics on account of sex; however, the meat from the female birds did have a higher intramuscular fat content. Season (winter vs. summer) did not influence the average muscle weights (g) of the breast, thigh, and drumstick portions, but the intramuscular fat content content of the birds hunted in winter was higher. Muscle color and pH differed as a result of season with the summer meat having a higher pH and more vivid red color compared with winter. The physical characteristics and the proximate composition of the breast, thigh, and drumstick portions varied considerably. This is essentially connected to a difference in physical activity of the muscles in the portions. Overall, this study revealed that to ensure a consistent eating quality the harvesting periods of Egyptian geese should be considered.
