Abstract | The objective of this study was to analyze the effect of genotype on the performance of crossbred cows in the peri-urban area of N’Djamena, in order to better guide the cattle breeders for dairy production. The study was conducted by survey in eleven (11) farms having two hundred and forty-three (243) crossbred cows. Data on breeder identification, dairy cow genetic types, quantity of milk produced, herd management, animal health and access to insemination services were collected and analyzed using XL-STAT software. Sixteen genotypes of crossbred cows were identified and their milk production compared. The analysis showed that the crossbred cows fromexotic bull breeds (Holstein, Montbeliard and Jersey)and local breeds (Kuri and Bokolodji) have proved to be the most favorable to improve milk production in theperi-urban area of N’Djamena. Nevertheless, the type choices of crossbred cows should be clarified after the monitoringof milk productions and their reproductive performance (age at first calving and calving interval). Moreover, poor livestock management (health, grazing and the transhumancemonitoring), difficult access to artificial insemination services by breeders and poor management of crossbreds are noted to be obstaclesof bovine milkproduction improvement in Chad.
