Résumé
The aim of our work is to control the growth performance of reproduction in both breeds of cows, Fleckvieh and Montbeliarde installed in livestock conditions Ouamri pilot farm (province of Medea). In order to evaluate the reproductive performance of dairy cows imported and weight of their calves after calving, the study involved 102 cows, 51 Fleckvieh and Montbeliarde 51. The results in the Fleckvieh and Montbeliarde are: The success rate at first insemination is 28.20% vs 23.81% ; The percentage of cows requiring projections 3 and older is 3.48% vs 46.43% ; The age at first calving 33.57 months vs 37.48 months ; The interval calving - calving is 470.96 j j vs 493 ; The calving-1st insemination interval 89.96j vs 94.5j ; The interval calving - fertilizing insemination 167.7 vs. 204.45 j ; The fertility rate is 84.61% vs 69.04% ; The fecondity rate is 79.48% vs 66.66%.
