Abstract

BACKGROUND

Participatory approaches of designing livestock breeding programs for tropical production systems have been extensively applied for rural livestock, whereas the peri-/urban livestock production sector tends to be widely neglected. In order to ensure the viability of the commercial cattle and sheep production sector in Ouagadougou, Burkina Faso, structured breed improvement programs are needed. The study aims to better understand selection decisions of cattle and sheep breeders and their trait preferences for local and imported breeds.

METHODS

49 cattle and 31 sheep breeders in peri-/urban areas of the city were approached in personal interviews. Data were analyzed in R version 3.5.1.

RESULTS

The main motivation for keeping cattle and sheep was to generate regular cash income through the selling of milk (cattle only) and surplus animals. Some (modern) breeders used imported breeds because of higher production performances. For imported cattle breeds, improved breeding technologies and management were applied to further enhance production outputs. Nevertheless, local livestock breeds were predominantly used due to their good adaptation.

CONCLUSIONS

Selection decisions and trait preferences for local and imported cattle and sheep breeds were strongly based on performance traits. Especially sheep breeders, but also traditional cattle breeders, did not record performance traits and did not take conscious breeding decisions.

摘要

背景

为热带生产系统设计家畜育种计划的参与式方法已广泛应用于农村家畜,而城郊家畜生产部门往往被广泛忽视。为确保布基纳法索瓦加杜古商业牛和羊生产部门的生存能力,需要制定结构化的品种改良计划。本研究旨在更好地了解牛和羊养殖者的选择决策及其对本地和进口品种的性状偏好。

方法

对该市城郊地区的49名牛养殖者和31名羊养殖者进行了个人访谈。在R 3.5.1版本中对数据进行了分析。

结果

饲养牛和羊的主要动机是通过出售牛奶(仅牛)和多余的动物来获得定期现金收入。一些(现代)养殖者因生产性能较高而使用进口品种。对于进口牛品种,采用了改良的育种技术和管理方法以进一步提高产量。尽管如此,由于本地家畜品种适应性良好,仍主要使用本地品种。

结论

对本地和进口牛和羊品种的选择决策及性状偏好很大程度上基于生产性能性状。特别是羊养殖者,还有传统牛养殖者,没有记录生产性能性状,也没有做出有意识的育种决策。
