The influence of gender on the physical and chemical properties of the M. longissimus dorsi et lumborum of mountain reedbuck (Redunca fulvorufula) was examined. The mean live weights of ten male (28.58 kg) and nineteen female (30.58 kg) mountain reedbuck did not differ (P>0.05), and the mean cold carcass weight was 16.36 kg for both genders. Gender had no influence (P > 0.05) on any of the physical characteristics (pH, drip loss, cooking loss, shear force, colour) investigated. For the proximate chemical analysis of the M. longissimus dorsi et lumborum muscle, the effect of gender was only significant for the protein content, where the females (24.51%) displayed a higher percentage of protein compared to the males (23.68%). Neither the amino acid nor the mineral content differed significantly between the two genders. Glutamic acid (11.35 g/100 g) was the most abundant amino acid, followed by aspartic acid (2.94 9/100 g), glycine (0.86 g/100 g) and serine (0.66 g/100 g). The mineral content of mountain reedbuck indicated that meat derived from this species is high in phosphorus (206.47 mg/100g), high in iron (4.19 mg/100g), a source of zinc (1.80 mg/ 100g), and low in sodium (4.19 mg/100 g). No significant differences between the genders for total saturated fatty acids (38.09%), total mono-unsaturated fatty acids (18.04%) or total polyunsaturated fatty acids (43.74%) were noted. The mean polyunsaturated:saturated fatty acid ratio for mountain reedbuck was 1.15 and the mean n-6:n-3 PUFA ratio 2.08. The extent of the influence of gender on physical and chemical characteristics of meat was found to be of limited practical value

The aim of this study was to investigate the effect of different seasons and gender on the physical and chemical composition of black wildebeest (Connochaetus gnou) meat. Twenty-six black wildebeest were harvested at Maria Moroka Nature Reserve, in the Free State Province, South Africa, during winter, spring and autumn. Mean body and carcass weight did not differ (P > 0.05) between either seasons or genders. However, dressing percentage was higher (P 0.05) between seasons, whereas differences (P < 0.05) in temperature of carcasses measured 24 h post-mortem could be ascribed to differences in ambient temperature. Meat from animals harvested during spring (5.52 and 39.63%) had a higher (P ≤ 0.05) drip and cooking loss compared to those harvested in winter (2.27 and 34.59%) and autumn (3.61 and 33.88%). Meat was the most (P < 0.05) tender during autumn (2.27 kg/1.27 cm diameter) while that of females was more tender than the males. The colour of the meat was darker in winter (L-value of 28.90) compared to spring (34.08) and autumn (32.91). Protein content of the m. longissimus dorsi was lowest (P < 0.05) in spring (20.45%). Lipid content was highest (P < 0.05) in winter (1.22%) and also lowest (P < 0.05) in males (0.90). Although season has significant Influences on some physical and chemical characteristics of meat from the black wildebeest, the extent of these differences does not necessitate a different classification system
