Abstract

The aim of this study was to investigate the live weights at birth (BW), weaning (WW), sixth (SW), twelfth (TW) and eighteenth (EW) months of age by cluster analysis in Konya Merino sheep. k-means clustering methods was used for the cluster analysis. Clusters were obtained differently according to sex and birth types. Effects of dam age on BW, WW (P<0.01) and SW (P<0.05) were found to be significant and its effects on TW and EW were not significant in single born females. Dam age did not affect BW, WW, SW, TW and EW in twin born females and single born males. In twin born males, dam age affected only SW (P<0.05). By the statistically analyses different cluster numbers were determined as 6, 5 and 4 for single born females, twin born females, single and twin born males respectively. The differences between the clusters in respect of live weights at the same ages were statistically significant (P<0.01). At the end of the study, according to live weights at eighteenth month of age, the third cluster for twin males and the first cluster for single females gave the highest values.
