Niger’s local breeds have low production parameters. The Azawak breed was selected for genetic improvement at the Toukounous station. Research has introduced crossbreeding through artificial insemination, importing semen from the Brune des Alpes bull to improve the breed’s performance. The study involved 75 crossbreds and 13 Azawak males. The aim was to determine the weights (at birth, typical age and live weights) and the weights of the different parts of the animal’s 5th quarter, as well as the carcass yield of the males (crossbred and Azawak). Birth weights for crossbreds and Azawak were 29.82 4.76kg and 22.78 1.78kg respectively. Live weight was 459.25 92.74kg for Azawak and 591.09 55.59kg for crossbreds. Carcass yields were 46.72% and 47.82% respectively for crossbreds aged 2 to 3 years and Azawaks aged 5 to 9 years. All this shows that crossbreeding gives a better vision to be continued to see the performances since this study is only one part of the research to draw the final conclusion on crossbreeding in Niger.

Abstract: (french)
Les races locales du Niger ont des paramètres de productions peu performants. La race Azawak a été sélection pour l’amélioration génétique à la station de Toukounous. La recherche a introduit le croisement à travers l’insémination artificielle en important la semence du taureau de la Brune des Alpes afin d’accroître les performances de cette race.L’étude a porté sur 75 croisés et 13 Azawak mâles. Le but est de déterminer les poids (à la naissance, à âge type et vifs) et les poids des différentes parties du 5ème quartier de l’animal ainsi que le rendement carcasse des mâles (croisés et Azawak). Le poids à la naissance des croisés et Azawak est respectivement de 29,82 4,76kg et 22,78 1,78 kg. Le poids vif est de 459,25 92,74kg chez les Azawak et 591,09 55,59kg chez les croisés. Le rendement carcasse est respectivement de 46,72% et 47, 82% chez les croisés âgés de 2 à 3 ans et Azawak âgés de 5 à 9 ans. Tout ceci démontre que le croisement opéré donne une meilleure vision à continuer pour voir les performances puisque cette étude n’est qu’une partie de la recherche pour en tirer la conclusion finale sur le croisement au Niger.
