Abstract
The researches were made on a sheep population of 8 rams of Suffolk breed, 51 ewes of Palas Merino breed and 54 male descendants to which the growths of live weight during the period from birth to 5 months were determined. The heritability of the growth and the breeding value of the rams were estimated by REML method [4]. The breeding value of the rams was also estimated by other two methods, [1], [2], [3], [5]. The value of h2= 0,55 for the growth of live weight at lambs makes the estimation of the breeding value of rams also efficient by the 2 presented methodologies, which are less modern comparatively to BLUP. In this case the selection by the own performance becomes also efficient.
