Research on growth performance, weight, daily average enrichment recorded on hybrids of the native Tzurcana breed with the two paternal breeds of French Vendeen and White of Central Massif were the objective of study and analysis of this paper. The study was conducted from the spring of 2018 on the sheep private farm of the County - Olt on the 180 females sheep, of which 30 were of the Vendeen breed to track the performance of the pure breed in our country. The other 100 females were cross with the two races to obtain F1 hybrids with Vendeen and BMC, and 50 were considered a control group of the pure Tzurcana native breed. All animals were subjected to control of calf weight W0 at 30 days of age W1 at 70 days W2 and W3 at 98 days of age. The results high lighted both the net superiority of the meat and the adaptability of the Vendeen paternal breed to the semi-intensive exploitation system towards Tzurcana; the prolificity was 140% versus 103% and a net average net increase of 72 g/day in females and 94 g/day in males in the first month of 90 g/day in both sexes in the 2nd month of growth respectively 91 g/day in females and 87g/day in males in the third month of growth. It is evident both the superiority of the pure paternal breed and the crossbreed obtained from the breeds with the breeds mentioned, regarding the assimilation-conversion capacity and the different growth rate in stages compared to the native breed, but between the crossbreeds the results are relatively similar to the small difference.
