The aim of the present work was to analyze the lactogenic potential in the second lactation of the F1 crossbreeds resulting from crossing the local sheep from the north-eastern area of the country with Awassi breed rams. To determine the total milk production, the control of milk production includes the suckling period of the lambs and the milking period of the ewes. The AT4 method was used in the milking period following the technical specifications recommended by the ICAR. During the suckling period, the amount of milk in crossbreds F1 sheep was 49.72 kg, and the production of milked milk was 95.13 kg. Average daily milk production on the 4 controls for F1 crossbred ewes was 774.37 ± 9.76 g with limits between 542 and 1006 g milk. The total production of milk obtained in 180 days at the second lactation of crossbreds F1 sheep was 144.85 kg, being 3% lower compared to that obtained by purebred Awassi sheep. The results regarding milk production at the second lactation of the F1 crossbred ewes are very good, so we recommend to breeders the use of crossing local sheep from the north-eastern area of the country with the Awassi breed for a significant improvement in milk production.
