Abstract: At the Institute of Palas in 2016 as a result of crossbreeding of two prolific breeds, Romanov and the Breed with High Prolificacy - Palas with Merino of Palas two hybrids with high prolificacy (hybrid 1 and hybrid 2) resulted. They have been verified comparatively to Merino of Palas regarding the slaughtering output and the particularities of the carcass. So, the slaughtering output at the hybrids and at the Merino of Palas was between the limits of 45, 71-48, 46 %, between genotypes not being significant differences. Regarding the indicators of the carcass there were significant differences only regarding the indicator of muscularity of the thigh (IMC) which had significantly bigger values (p < 0, 05) at the two hybrids comparatively to Merino of Palas. Regarding the tissue structure of the carcasses resulted at the hybrid 2 (F1 Prolific Breed of Palas x Merino of Palas) the rate of muscles in the carcass was significantly smaller and the rate of fat in the carcass was significantly bigger comparatively to Merino of Palas. In conclusion it can be said that the hybrid 2 (F1 Prolific Breed of Palas x Merino of Palas) has good carcasses (R class) but fat (class 4), by EUROP grid, hybrid 1 (F1 Romanov x Merino of Palas) has good carcasses (R) in proportion of two thirds and good enough (O) in proportion of one third, the carcasses being thin (class 2) but Merino of Palas has totally good carcasses (R) and fairly fat (class 3).
