Abstract: Growth performance, carcass characteristics, post-slaughtering and haematological parameters of Kivircik and Karacabey Merino male lambs in conventional and organic management systems were compared. The animals which were weaned at 7 weeks of age were divided into Kivircik conventional, Kivircik organic (KO), Karacabey Merino conventional and Karacabey Merino organic (MO) groups containing 12 lambs each. Fattening was ended when lambs attained 35 kg of live weight. The time to attain the determined fattening weight was significantly different among the groups, and Merino lambs having higher live weight gain were earlier than Kivircik lambs (p < 0.05). Overall conventional (CG) and organic group lambs were also compared. Live weight gain, intra-abdominal fat amount, external fat thickness and visceral organ weight were significantly higher in CG lambs (p < 0.05). Higher haematocrit and erythrocyte counts were obtained with the CG group (p < 0.05), whilst triglyceride, total plasma cholesterol and lipoprotein (HDL, LDL, VLDL) levels between groups were not significant. Pneumonia was the unique infection, with an incidence of 50% (six lambs) and 16.6% (two lambs) for MO and KO animals, respectively. The mortality rate was 16.6% (two lambs) for MO group, whilst no mortality was recorded for KO group animals. The present study has shown that although Karacabey merino lambs had higher growth performance compared to Kivircik lambs, organically fattened lambs in whole exhibited inferior growth performance. Lower infection and mortality observed with Kivircik lambs suggested that they could be more resistant to infections and outdoor environmental conditions.
