Abstract

Local genetic resources have an important place in poultry production in Africa. However, knowledge of these genetic resources and their breeding systems is quite often limited. This study was carried out in Seno province/Burkina Faso and aimed to characterize the local chicken production system, the genetic resources used and their management in this area. A survey was conducted including 185 chicken farmers in a rural area. The snowball sampling method was used to co-opt interviewees and, face-to-face interviews were done. The questionnaire includes closed and open-ended questions. Production system characteristics showed that local chickens were bred in free-range production system with few inputs. There were multiple production purposes such as self-consumption (meat and eggs), saving, sale, making donation to strangers. The sale of chickens was ranked as the main purpose with 0.48 as the index, and self-consumption of chicken meat came in second position with 0.34 as the index. According farmers, three phenotypes of chickens ("breed or ecotypes") are encountered in the area. However, these phenotypes are raised together with uncontrolled mating practice, leading to a tendency towards uniformity of phenotypes. Almost all farmers (98.9%) stated they select breeding roosters. This selection is mainly based on growth performance (96.6%). Nevertheless, they ranked "resistance to diseases" as the characteristic they would improve primarily if they had all the possibilities (index 0.43). In general, the production system was extensive with low input, whereas the local chicken genetic resources were under poor management which can lead to genetic erosion.

Abstract

Burkina Faso relies on its substantial bovine population for meat and milk production, ensuring food security. The country hosts three primary taurine cattle populations: Lobi, Gourounsi Nahouri, and Gourounsi Ténado. These cattle are adapted to local conditions and exhibit valuable trypan tolerant traits, playing a crucial role in sustaining local communities and holding cultural and socio-economic significance. This study aimed to assess the genetic diversity and structure of Burkina’s primary taurine cattle populations using 27 microsatellite markers. Blood samples from 143 cattle representing these populations were genotyped. The analysis included assessing genetic diversity, deviations from Hardy-Weinberg equilibrium, calculating genetic distances, and population structure. The results revealed that all loci were polymorphic, indicating high allelic diversity. The overall mean FIS was moderate (0.028), ranging from -0.36 (CSRM60) to 0.73 (INRA035). Genetic differentiation between populations was moderate, accounting for 4% of the total differences. The highest pairwise FST was observed between Lobi and Gourounsi Ténado. The neighbor-joining tree displayed high admixture levels between Gourounsi populations, while Lobi cattle clustered as a distinct population. The population structure analysis indicated significant zebu gene introgression in Burkina taurine populations with relatively higher levels of admixtures in Gourounsi cattle compared to Lobi. The study provided a thorough genetic analysis of Burkina Faso's taurine cattle populations, uncovering the diversity and population structure. The study also revealed the differences in the prevalence of tsetse flies and associated trypanosomosis across the native tracts of Burkinabe taurine cattle populations had shaped the level of zebu introgression in them.
