Abstract
The aim of the research was to identify new methods to increase milk production insheep. An evaluation of milk production at Ţigaie local breed, in comparison withhalf-breed females from crossbreeding of local breed sheep with Awassi rams (Awx Ti) and with Lacaune (La x Ti) was conducted. Estimation of milk productionwas done according to given by International Committee for Animal Recording(AT method) and statistical analysis was performed using the Restricted MaximumLikelihood method. Mean milk production in Aw x Tiewes was 29, 28% higherthan in local breed Ţigaie, and 32. 20% higher than in La x Ti ewes. Differences ofmilk yield found in three groups of animals were very significant (p<0. 001). Basedon obtained results it could be concluded that crossbreeding of Ţigaie with Awassibreed rams had a better effect on increasing of milk production than crossbreedingwith Lacaune breed rams.
