The researches were made on a population of 51 F1 Boer x Carpathian male kids, descendants of 8 bucks of Boer breed. The kids were fattened for 100 days since the age of 80 days to 6 months, during this period the individual growths of live weight being registered. The heritability for the growth of the live weight was calculated according to the methodology presented by  and . The estimation of the breeding value was made according to the methodology used by  and . The estimated value of h2 for the growth of the live weight at kids was of 0.39. From the 8 bucks which were progeny tested, only 3 were improvers. In elaborating and developing a program of improving the meat production at goats, the use of bucks which were tested improvers for the growth of live weight of the kids until the age of delivery (6 months) becomes necessary.
Key words: Coefficient of heritability - h2, breeding value
