Pratiques d’élevage et indicateurs morphométriques de performance laitière chez les éleveurs de bovins Kouri au Niger
2017
In the Diffa region of Niger, a survey was carried out in 140 farms to analyze the breeding practices and dairy performance of Kouri cattle. In addition, morphometric traits that were indicators of dairy performance according to the farmers were documented. Most of the herders were sedentary and the majority of herds were medium-sized (36 ± 30 head per farm). For cows with the most recent complete lactations, milk production per cow was on average 2.7 ± 1.4 liters per day for an average lactation duration of 7.2 ± 2.8 months. For cows considered as the best dairy cows, milk production per cow was 4.2 ± 1.5 liters per day for an average lactation duration of 8.9 ± 2.7 months. Although breeding practices were similar for many aspects in the different ethnic groups, morphometric selection criteria for Kouri dairy cows varied according to the ethnic group. The phenotypic characteristics thus associated with the Kouri breed in the identified ethnic groups were mainly the pelvic length, chest width, teat length, withers height, and tail length. It is important to consider endogenous knowledge of genetic improvement because the morphometric parameters identified in this study as performance indicators were not unanimously accepted within the ethnic groups.
