The effectuated research aimed to analyse the improvement possibility of milk production at goats on the basis of the application of a cross-breeding programme between Carpatina breed domestic females with male reproducers belonging to some more productive breeds and which proved that have a higher capacity for improving the milk production at half-breed populations. Biological material was represented by goat populations which belong to different breeds, respectively autochthonous Carpatina breed (LM) as well as other half-breed groups of first generation resulted by cross-breeding domestic breed females with male reproducers belonging to Anglo-Nubian breed (L1) and French Alpine (L2). To compare the results and ameliorative effect due to cross-breeding, especially on milk production capacity, were utilise3d data obtained after application of performances productive control. The applied working methods for estimation of milk production were based on technical norms which regulate effectuation of official control for milk production at farm animals accepted in experimental technique and recommended by International Committee for Animal Recording. Based on applied productive control was observed that between L1and LM exist a real difference for total milk production of 17.74 kg milk, difference which have a high degree of statistical significance for P>1%. In case of cross-breeding of batch L2 in comparison with autochthonous goats the real difference between level of mean milk production is 23.30 kg milk being distinct significant for P>1%.
