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

Abstract

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.

Dynamique de l’involution utérine et de la croissance folliculaire pendant l’anoestrus postpartum chez le zébu peulh d’Afrique

“…Les données sur la dynamique des follicules ovariens et les caractéristiques de l'involution utérine au cours du postpartum chez le zébu Peuhl sont peu documentées. Contrairement aux zébus Azawak et Goudali, le zébu Peuhl présente des exigences fourragères moins élevées, s'engraisse facilement et résiste mieux aux maladies transmises par les tiques (Touré et al, 2019 ;Yahaya et al, 2019).…”
