Abstract | Age at first calving for twenty crossbreed cows was estimated at 35.62 ± 11.04 months by using artificial inseminations sheets and calving records on three cattle farms in urban and suburban areas of Bobo-Dioulasso. The effects of crossbreeding type, bull races, crossbreed cow generations and farm sites were analyzed. However, crossbreeds have been more precocious than the local cattles. In addition, the inseminations of Fulani zebu using Montbeliard and Alps Brown semens, the 2nd generation of crossbreed cows and the increase in farm level intensification were favourable for crossbreeds sexual precocity (p <0.05). However, to the better selection guide of cattle-breeders, calving interval and the milk production level must be assessed in order to identify the crossbreed type for optimal and profitable operations.
