Abstract
    Due to the increase the interest for the lamb meat on international and national level we aimed to optimize the technology of fattening the lambs and to obtain the improvement of the carcasses through the use of crossbreeding the local sheep breeds with sheep breeds for meat. It was done the intensively fattening of 100 days. The weigh increasing rates were bigger at the lots of half-bred lambs, being big differences between the half-bred lambs and the lambs from the witness lots formed from lambs of maternal breeds: F1 half-bred lambs (Meat Breed of Palas x Palas Merino Breed) made a daily average increasing rate of 234.11± 9.9735g, the lambs from Merinos de Palas breed 190.05 ±9.0261g, the lambs of Meat Breed of Palas 219.40±8.7212g the F1 half-bred lambs (Meat Breed of Palas x Ţigaie) 193.50±7.5896 g, lambs of Ţigaie Breed 130.71 ± 2.1045 g, half-bred lambs of F1 (Suffolk x Merinos) 200.60±4.1035g, lambs of Merinos Breed 167.31±2.1735 at first sheep breeder, half-bred lambs of F1 (Charollais Breed x Merinos Breed) 238.12±3.1735g lambs of Merinos Breed 185.23±2.1525 , at the second sheep breeder. At the slaughtering of control there were obtained bigger values of the output at the half-bred lambs. At the appreciation of the carcasses through EUROP grid the half-bred lambs had the carcasses classified in U class, and the carcasses of the parental breeds (Tigaie and Merinos) in R class.
