Aims: The aim of this study was to investigate lamb growth from birth to weaning and the relationships between different body measurements with fattening characteristics for Awassi sheep lambs.Methods and Results: This study was carried out with Awassi sheep lambs reared in Kilis province of Türkiye. Lambs are weaned at 60 days of age. Twenty head of male lambs, with similar weaning weights and approximately 3 months of age (between 80-95 days) were selected in order to determine the fattening performance of the lambs born in the flock. The lambs were weighed at 14-day intervals in the fattening period, which continued for 70 days. The lambs consumed the concentrate containing 16% crude protein and 2600 kcal ME and alfalfa hay as ad lib. Birth and weaning weights of the lambs were determined as 4.29±0.061 kg and 12.93±0.209 kg, respectively. The daily weight gain and feed conversion ratio were calculated as 241.0±9.83 g and 5.4, which continued for 70 days of fattening period. Conclusions: Positive and significant phenotypic correlations were determined between the live weights of the dams and the birth weights of the lambs. In addition, a positive and high phenotypic correlation was determined between body length and live weight at the end of the fattening for the lambs.Significance and Impact of the Study: At the end of the study, it was determined that the birth season affects the development of the lambs, there is a positive relationship between body length and final fattening weight for the lambs. For this reason, spring births in Awassi sheep production can be recommended to the breeders. In addition, it may be recommended to consider body length for choosing fattening material.
