Simple industrial crossing of local sheep breeds with specialized breeds for meat production is the fastest method to increase the quantity and quality of meat production. Our research aimed to study the growth rate abilities in intensive and semi-intensive fattening system of F1 crossbred lambs obtained by crossing Tsigai sheep of the rust variety with rams of meat breeds from France, namely Vendeen, Blanche du Massif Central, and Berrichon du Cher. The experiment was carried out at the biobase of the RDSSGB Secuieni-Bacău research station during 2020-2021. At the beginning of fattening, the lambs were 60 days old and had an average body weight ranging from 14.55 kg for the Tsigai breed batch to about 18.41 kilograms for the F1 crossbred lambs. In the case of both fattening systems, the batches of crossbreds belonging to the Vendeen x Țigaie and Berrichon du Cher x Țigaie variants stand out, which recorded a delivery body weight of 40 kg at an average age of approximately 142-143 days in the case of the intensive fattening system and 166-167 days in the case of the semi-intensive fattening system.
