Abstract
The Berrichon du Cher breed is a French meat sheep breed, specialized in production of high-quality meat. The demand of the EU market for the sheep meat is focused, especially in the western countries, on the high quality cuts of the sheep meat and the demand very low on unspecialized meat breeds like the local Tsigai breed. In order to improve the production efficiency Berrichon du Cher rams were crossed with Tsigai ewes. The lambs were compared with purebred igai lambs to evaluate daily weight gain from birth to 120 days. The daily weight gain was superior in the hybrid lambs compared with purebred lambs.

Our studies had focused on evaluation of the heterosis effect by crossing Berrichon du Cher rams with Tsigai ewes regarding the weight of the resulting lambs at birth, 21 days, 50 days, 90 days and 120 days
The analysis considered the daily weight gain, the comparative evaluation of body weight concerning the age, sex and purebred lams with F1 crossed lambs
Summary
The Berrichon du Cher breed is a French meat sheep breed, specialized in production of high-quality meat. Our studies had focused on evaluation of the heterosis effect by crossing Berrichon du Cher rams with Tsigai ewes regarding the weight of the resulting lambs at birth, 21 days, 50 days, 90 days and 120 days. We have formulated two hypotheses, according to the null hypothesis, the body weight of the crossbred Tsigai ewes with Berrichon du Cher rams and purebred Tsigai lambs is equal, regardless of the moment when the weighting is performed.
