The aim of the work was to investigate the impact of the application of hormones during the three seasons a year, in order to increase the reproductive efficiency of sheep Virtemberg race, as well as the effect of applied hormones on the ovary treated sheep. At the examined the impact of the application only gonadotropin (PMSG) at the first sample group, while for the other sample group examined the impact of applying a combination progesterona (FGA) and gonadotropin (PMSG). Tested the following reproductive characteristics: a) oestrus response after application of hormones during three seasons per year, b) interval from the application of hormones to appear oestrus, c) the results of conception and d) the results of lambing. Values measured feature sheep race Virtemberg were following: the value estrusnog reactions after treatment with PMSG only, in three different seasons per year was 20 % (early anestrus), 45% (late anestrus) and 45% (mating season) while the value oestrus reactions after treatment with FGA and PMSG was 64%, 80.5% and 91.7%, the highest number of treated sheep was entered in oestrus within the first 6 days after giving PMSG (early anestrus 71.4%, late anestrus 87.5% in the mating season, 100%) as well as the combination of FGA and PMSG (78.3%, 82.7% and 100%) ; value conception ranged between 83.3% and 93.7% using only PMSG and 81.8% and 94.1% using a combination of FGA and PMSG; lambing results after application of the PMSG are moving between 1.53 and 1, 60, while after application of a combination of FGA and PMSG move between 1.56 and 1.66. These results indicate that application of hormones is a good method, because all the test parameters were satisfactory, and that can be successfully used in a wide sheep practice in the area where it was applied.
