Abstract
   Due to the raise of interest for goat milk we have been concerned with the increase of milk production from the goats of Carpathian breed (ecotype of Dobrogea) by crosbreeding with Saanen beed and Anglo-Nubian breed. By crossbreeding with milk breeds it was obtained a substantial improvement of the milk production at the obtained half-bred (F1 Saanen x Carpathian and Anglo-Nubian x Carpathian). The milk production and the lactation period increased at the two lots of half-bred, producing a raise of the total quantity of milk, from 235.21 ± 6.7 liters, in 214 days of lactation, as it was the average production at the effective of goats of Carpathian breed, at a total average milk production of 286.27 ± 5.2 liters, în 229 days of lactation, at F1 half-breds of Saanen x Carpathian and 297.32 ± 6.2 liters in 231 days of lactation at the half-breds of Anglo-Nubian x Carpathian. The quality indicators of the milk at goats had a trend of raise to the end of the lactation period at all lots, the average values on the whole lactation period of the main components of the milk, fat and protein at the half-bred goat were bigger comparatively to those from Carpathian breed, with 8.49% at fat and 8.72% at protein at F1goats of Saanen x Carpathian and 6.79% at fat and 6.97% at protein at the F1 goats of Anglo-Nubian x Carpathian.
