Abstract
The researches focused on the assessment of milking capacity of mother ewes on the growing rhythm of the own littered lambs. The biological material belonged to Turcana breed, structured on age periods as, reported to the generations. It resulted, after the researches were finished, that the average milk yield was of 94.234 l during the first 85 days of lactation, at the studied sheep population. The high performance achieved for milk yield confirmed the very good milking capacity of Turcana ewes with straight consequences on the lambs growing speed, right after parturition. The correlation coefficient for the following traits pair - suckled milk quantity and lambs growing speed presented higher values, rp: 0.84 during the 0-15 days age period and rp: 0.79, for the 16-28 days period. The strength of correlation between milk yield and growing speed decreased at rp: 0.46 for the age period of 43-55 days, respectively at rp:0.24 for suckling period comprised between 71 and 85 days.
