“…The mean AFC of the crossbreeds was lower than those reported among the Zebu under the tropics at more than 40 months reported in many studies (Rahman et al, 2016;Tellah et al, 2015aTellah et al, , 2015bBashir and El Zubeir, 2013;Sokouri et al, 2010;Bayemi et al, 2005). This shows that crossbreed cows are sexually more precocious than tropical cattle (Wassie et al, 2015).…”

| 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 2 nd 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.

“…Age at first calving reported by several authors happens after 45 months (Tellah et al, 2015a(Tellah et al, , 2015bBashir and El Zubeir, 2013;Sokouri et al, 2010;Bayemi et al, 2005). This sexual precocity delay results from a combination of genetic, biological, environmental factors and those associated with herd management (Adamou N' Diaye et al, 2003).…”

“…The milk production of the local Zebu Azawak breed was significantly different from the other local breeds (Zebu Peul and Zebu Maure) under the same breeding conditions. This could possibly due to not only a non-adaptation to better southern condition but also the physiology of the animal adapted to Sahelian conditions [12,13]. The superiority of Holstein and Montbeliard crossbreds, respectively, of 2210±548 kg/lactation versus 681±411 kg compared to the local breeds has been confirmed over several years and under the same farming conditions (Figure-3) [14].…”

Phenotypic parameters affecting reproduction and production performances of dairy cattle in peri-urban of Bamako, Mali

Aim: The present study was conducted to evaluate the reproduction and production performances of crossbred and local dairy cattle in peri-urban of Bamako, the capital of Mali. Materials and Methods: A total of 17 randomly selected households with 450 dairy cattle from four peri-urban of Bamako were individually interviewed, given register format and divided into four focus group discussions. The participants were dairy farmers and they were asked to know the phenotype that seems to them the more interesting for the reproduction and production performances of their dairy cattle. Results: The calving interval (CI) obtained exceeded 433 days in all phenotypic types with average milk yields of 5.13±1.84 kg/day, 4.76±2.41, and 3.05±1.32 kg/day, respectively, for the Holstein crossbred, Montbeliard crossbred, and the local breeds (Zebu Peul and/or Zebu Maure). Crossbred was more productive than local breeds with significant (p<0.05) differences for lactation length, CI and total production and not significant on parity. The results also showed the advantages of the crossbred cows in terms of CI (460±80 days) compared to local zebus breeds (433±115 days) to keep the time of milking as long as possible. However, the Zebu Azawak breed whose cradle is located in Northern Mali, managed under extensive peri-urban rearing conditions, has less favorable production parameters than those of other local cattle breeds in milk production (636±43.3 kg vs. 681±41.1 kg). Conclusion: The present study revealed that crossbred dairy cattle performed better in terms of CI, lactation length, and production compared to the local breeds. The study also showed that the local Azawak breed numerically performed less compared to the other local breeds evaluated in this study, namely, Peul and Maure.

“…La sex-ratio était en faveur des mâles (69,2 %). Elle était supérieure aux 63 % obtenus par Kouamo et al (2020) chez les femelles Goudali x Charolaises au Cameroun mais inférieure aux 48 % rapportés par Tellah et al (2015) chez les bovins Kouri du lac Tchad. Cette différence pourrait s'expliquer par la taille de la population.…”

L’étude a eu pour objectif d’évaluer deux protocoles de synchronisation des chaleurs à base de prostaglandine F2α (alfaprostol 2 mg), l’un court à injection unique et insémination artificielle (IA) sur chaleurs observées, l’autre long à double injection à 11 jours d’intervalle et IA à temps fixe 80 heures après la seconde injection. Elle a porté sur 72 vaches et 12 génisses de race Goudali, toutes cyclées. Les semences utilisées ont été celles des taureaux Bruns Suisses, Aubracs et Gascons. Le taux d’induction des chaleurs a été de 100 %, avec un délai de 2 à 11 jours postinjection pour la venue des chaleurs en protocole court. Après un minimum de 60 jours post-IA, une palpation transrectale a été effectuée, ainsi qu’un suivi des gravidités jusqu’aux vêlages. Les taux de gravidité, d’avortement et de vêlage ont été respectivement de 17,8 %, 13,3 % et 15,4, soit respectivement pour les protocoles court et long 30,8 %, 16,6 % et 25,6 %, et 6,7 %, 0 % et 6,6 % (p < 0,05). La durée moyenne de gravidité a été de 290 ± 4,5 jours, soit respectivement pour les protocoles court et long 290 ± 4,5 jours et 289,7 ± 5,8 jours (p = 0,181). Le poids moyen des veaux à la naissance a été de 22,9 ±1,4 kg, soit respectivement pour les protocoles court et long 22,9 ± 1,6 kg et 23,0 ± 1,0 kg (p = 0,319). La sex-ratio (% de mâles par rapport à la population totale) a été de 69,2 % (p = 0,6). Les animaux présentant une durée post-partum entre 5 et 10 mois, dont l’IA avait été pratiquée dans le corps de l’utérus et entre 16 et 17 heures après la détection des chaleurs, ont présenté une meilleure fertilité (p < 0,05).
