SIMELA, L.; WEBB, E.C.  e  BOSMAN, M.J.C.. Acceptability of chevon from kids, yearling goats and mature does of indigenous South African goats: A case study. S. Afr. j. anim. sci. [online]. 2008, vol.38, n.3, pp. 247-259. ISSN 2221-4062.

Consumer sensory evaluations of oven-roasted goat and sheep m. longissimus dorsi samples were conducted in two series to determine the acceptability of chevon from indigenous South African goats to consumers. Chevon samples were from goat carcasses of known description. In series I, castrate and female goats and female sheep, all with 2 - 6 permanent incisors, were compared. Castrate males were significantly heavier and yielded heavier carcasses than the female goats. Nonetheless, the two groups did not differ significantly in carcass and meat characteristics. Cooking losses from mutton samples were significantly higher than losses from chevon from female goats only. In series II, male kids (milk teethed), old does (8 permanent teeth) and sheep (2 - 6 permanent teeth) were compared. Does were heavier at slaughter, but the mean carcass weight did not differ significantly from that of the kids. There were no significant differences between the does and kids in carcass tissue composition and sarcomere lengths. The pHu of does was significantly higher than that of kids. Cooking losses from mutton and chevon samples in series II did not differ significantly. Amongst the consumer characteristics, level of education was the most important determinant of consumer acceptance of the sensory attributes and intended frequency of consumption in both series. Population group was a significant factor in the judgement of the more diverse meats of series II only. Sensory evaluations indicate that all meat types were highly acceptable to the consumers who on average were willing to eat any of the meats at least once a week. The study indicated that chevon from indigenous South African goats is acceptable to consumers and may be as acceptable as mutton, provided that the meat is from goats of about two years of age or younger.
