Abstract


The aim of the study was to compare the population of animals from the farm with the breed standard regarding prolificacy and also the influence that the change of the growing environment had on the reproduction indices.
The study was effected on the “ Mănuca Mihaela P.F.A.” farm, which is located at about 11 km from the town of Flămânzi in Botoșani county. The farm covers an area of 2 hectares, and consists of a shelter with three related annexes, feed base, milking parlor and manure platform.
Currently, the farm has a total of 282 ewes, 10 rams, 100 young females from the previous year and 12 young males from the previous year.
Out of the total of 282 females studied, 186 of them lambed twins and out of this number, 48 of the females were primiparous and 138 were multiparous.
In according to the literature, the Lacaune du lait sheep breed has an average prolificacy of 145% in primiparous and 170% in multiparous. In the studied farm, the prolificacy had values of 144,4 % for primiparous and 179,3 % for multiparous females.
