Abstract
The aim of our study was to evaluate the gradient of milk yield, of milk biochemical composition and fatty acids profile according to breed, for primipara goats from Carpathian breed and Saanen x Carpathian and French Alpine x Carpathian half breed that were grown in semi-intensive system (Dobrogea, South Romania). The studies were performed on goats raised at ANCC CAPRIROM farm, located in Constanta, Romania. The biochemical parameters (fat, proteins, lactose) were studied by electrochemical method with a Lactostar analyzer Funke Gerber type specialized for goat milk. Milk fatty acids profile, as fatty acids methyl esters (FAME), was determined by chromatographically gas method. The considerable high protein content found in half breeds, might be explained by the fact that bucks from specialized breeds such us Saanen and French Alpine which were used for half breeding, come from imported animals from France, which were locus genotyped for alpha S1 casein gene and were selected dominant genotypes that lead to a higher protein concentration in milk.The statistical analysis shows that the milk coming from Carpathian does and their half breeds is not significantly different regarding the levels of various fatty acids, saving omega 3 acids, which are considerable higher at Carpathian does, proving that food has the decisive role regarding composition.
Highlights
In Europe, the raising of milk goats is mostly encountered in the Mediterranean basin (Spain, France, Italy and Greece), where yields obtained from raising goats represent an important economic, social and environmental mean of progress

Summary
In Europe, the raising of milk goats is mostly encountered in the Mediterranean basin (Spain, France, Italy and Greece), where yields obtained from raising goats represent an important economic, social and environmental mean of progress. Researches done in Romania and in some East European countries, established that breeds and local populations, from lowland and hills areas, can be bred by crossbreeding with best individuals from Saanen and French Alpine breed. The aim of our research was to evaluate the gradient of yield milk, biochemical composition and milk fatty acids structure based on breed for primipara goats of Carpathian breed and half-breed Saanen x Carpathian and French Alpine x Carpathian, raised in semi-intensive system (Dobrogea, South Romania). The studies were performed on primipara goats of Carpathian breed, half breed F1 Saanen x Carpathian and half breed F1 French Alpine x Carpathian, kept at ANCC CAPRIROM farm located in Constanta, Romania. Three groups of 40 primipara Carpathian goats, half breed F1 Saanen x Carpathian and half breed F1 French Alpine x Carpatian were organized after ending the calving period in February 2017. The fatty acids profile of goat milk, as fatty acids methyl esters form (FAME), were conditioned by chromatographic gas method [2]
