Abstract

Crossing of local sheep breeds with specialized breeds for meat production in order to obtain crossbreeds with superior meat characters is a rapid method of increasing quantitative and qualitative meat production. The main aim of our research was to study the productive abilities for meat production of crossbreeds obtained by crossing Tsigai breed from the rust variety with rams of French meat breeds, namely Vendeen, Blanche du Massif Central and Berrichon du Cher. The experiences took place within the biobase of the RDSSGB Secuieni Bacau research station in the period 2018-2020. The results obtained show that the heterosis has a higher manifestation on the productive performance in the F1 crossbred lambs (Berrichon du Cher x Tsigai) with very significant differences being found (P<0.001) in the average body weight of all ages compared to the maternal breed, followed of F1 crossbreds (Vendeen x Tsigai) with highly significant differences (P<0.001) in the average body weight at birth, 100 days and at 6 months and with significant differences (P<0.05) at the age of 60 days. As a result, the Berrichon du Cher and Vendeen breeds have a better degree of genetic combinability with the local Tsigai breed, the resulting F1 crossbreeds having, in the case of intensive fattening, clearly superior performances to the local breed, being able to be used by farmers at any age after weaning. The F1 crossbreds (Blanche du Massif Central x Tsigai) can be used by farmers only after the age of 100 days, the weight gain up to this age being much lower than the other two crossbred variants.
