Some meat yield and quality properties of karya genotype on different fattening conditions

In this study, fattening performance, slaughter and carcasss properties with meat quality and fatty acid composition are determined in male and female of Karya lambs in pasture, pasutre+feeding and intensive conditions. Research was conducted in 2008 and 2009 and total 72 lambs were used to be experimental materials. Live weight gain was obtained the highest in intensive group as fort he lowest value was in pasture lambs during fattening. While the lowest dressing percentage (% 44.94) was found in the first group, this properties was calculated more high in female lambs. On the basis of all Carcass parts, between male and female and fattening groups were not significant for statistically. Significant differences were obtained between groups in M.Longissimus Dorsi muscle for L* (lightness) and the highest value was calculated in third groups and male lambs. The meat colour was emerged more red (high a* value) in this group and their male lambs. The intermusculer fat (marbling) was evaluated better in intensive group and male lambs. When fatty acid composition was evaluated, while the SFA and MUFA were increased in intensive conditon, C16:0 was the highest, C18:0 and C18:1 n-9 were the lowest value in pasture lambs. In this study was emerged that the pasture feeding was raised the P/S, CLA and n-6 PUFA/n-3 PUFA values.
