Abstract
The aim of this research was to demonstrate the possibility for crossbreed between the Romanian sheep Merino Palas and the sheep breeds specialized for the lambs with high meat quality productions. In this way have been analyzed two different sheeps batches as follows: the basic batch consisting of 50 animals Merino Palas pure breed sheep and an experimental sheep batch consisting of 50 sheep Merino Palace mated with rams Ile de France sheep breed. For the body weight determinations it was calculated average weight gain of lambs at birth, at one month, at two month, at three month and at the delivery age (5 month about). After the weaning, the lambs were maintains in the unified conditions, and such the specific consumption index is not determined for each animal lot. The slaughter's results were calculated on the 5 lambs for each animal batch. Based on experimental results the following conclusions can be drawn:
- the body weight of the crossbreed lambs was better comparative with the basic sheep batch.
- the slaughter's results of crossbred lambs were better comparative with the lambs of basic animal batch.
- the crossbred lambs achieved a high qualitative meat carcass, with a better commercial range, comparative with lambs of a basic batch.

Key words: sheep breed, lambs, meat carcass
