Abstract: The present study aimed to determine the effect of different weaning ages on the fatty acid composition and nutritional value of rack joints (6th-12th ribs) of male Akkeci (white goat) kid carcasses. The study consisted of 15 heads of kids weaned at 45, 60 and 75 days of age. All kids were slaughtered when they reached approximately 27 kg commercial slaughter weight. There were no significant differences in nutritional value or collagen content among the groups. C 14:0 content was significantly higher in the group of kids weaned at 75 days (p<0.05) when compared to other groups whereas C 17:0 content was significantly higher in the group weaned at 45 days (p<0.05). There were no significant differences in total saturated and unsaturated fatty acids of rack joint fat tissue among groups. However, kids weaned at 45 and 60 days of age had significantly higher total mono-unsaturated fatty acids than those weaned at 75 days (p<0.05). C 18:1 content (p<0.05) greatly affected the differences in mono unsaturated fatty acids among groups. In conclusion, contents of some fatty acids in kid rack joints may be affected by differences in milk and concentrate consumption resulting from differences in weaning ages.
