Effects of different fattening systems on fattening performance and body measurements of hemsin male lambs [Hemşin erkek kuzulari{dotless}nda farkli{dotless} besi sistemlerinin besi performansi{dotless} ve vücut ölçülerine etkisi]

This study was conducted to determine effect of different fattening systems on fattening performance and body measurements of hemsin male lambs. the materials of the study were consisted 39 male lambs weaned at 3 months of age (approximately live weight of 23 kg). in this study,hemsin lambs were used in three group of extensive (n=13),semi-intensive (n=13) and intensive (n=13). the experiment was conducted for 90 days. final live weights of groups of extensive,semi-intensive and intensive were 33.32,41.16 and 42.09 kg,respectively,and for daily live weight gain (dlwg) were 121.11,201.89 and 213.00 g,respectively. for semi-intensive and intensive of group,feed conversion ratios were 3.44 and 5.35 kg,respectively. as a result,intensive and semi-intensive groups of fattening performance were higher than that of extensive group. the differences among intensive and semi-intensive groups of fattening performance were not statistically significant (p>0.05). the results of this study suggest that semi-intensive group might be appropriate for fattening male hemsin lambs. hemsin lambs had a generally similar or lower fattening performance compared to local sheep breeds.
