Abstract

BACKGROUND

Indigenous village chickens, or (IVCs), significantly contribute to rural livelihoods. Although natural selection has a disproportionate impact on the genetic structure of IVCs, farmers have developed locally tailored breeding practices to get the most out of their flocks.

OBJECTIVES

Small-scale farmers' insights on trait breed preferences and family flock breeding practices are presented in this cross-sectional study.

METHODS

A cross-sectional study was conducted in two agroecological zones using face-to-face individual interviews with 119 general informants.

RESULTS

Farmers prefer IVCs because they are multipurpose birds. Unlike policymakers, who usually underestimate the importance of IVCs, small-scale farmers acknowledge the coexistence of local and commercial chickens. Only 15.7% of farmers recruited homegrown cocks, whereas 47.9% outsourced breeding cocks from local markets and 36.4% from neighbours (χ-squared = 15.976, df = 2, p = 0.0003395). About 49.2% of small-scale farmers believed that consanguineous mating-induced inbreeding has only trivial effects. High flock turnover significantly reduces inbreeding. Regardless of the low production capacity, small-scale farmers prefer local (rank = 1.47) chickens to commercial (rank = 1.61). For cocks, fertility and growth traits were highly sought after, whereas for hens, maternal instincts and laying performance were prioritized. Compared to the highlands, the lowlands had a longer egg storage period (t = 2.677, df = 117, p = 0.009, 95% CI: -3.7607, -0.5622).

CONCLUSIONS

This study documented the wisdom of small-scale farmers and encouraged the incorporation of their insights into a sustainable genetic improvement program.

摘要

背景

本土鸡(IVC)对农村生计有重要贡献。尽管自然选择对 IVC 的遗传结构有不成比例的影响,但农民已经开发出因地制宜的养殖实践,以充分利用他们的鸡群。

目的

本横断面研究介绍了小规模农民对特征品种偏好和家庭鸡群养殖实践的见解。

方法

在两个农业生态区进行了横断面研究,采用面对面的个人访谈方式对 119 名一般信息提供者进行了访谈。

结果

农民喜欢 IVC,因为它们是多用途的鸟类。与通常低估 IVC 重要性的政策制定者不同,小规模农民承认本地鸡和商业鸡的共存。只有 15.7%的农民招募自家公鸡,而 47.9%的农民从当地市场和 36.4%的邻居那里采购种公鸡(卡方检验 χ2=15.976,df=2,p=0.0003395)。大约 49.2%的小规模农民认为近亲交配引起的近交只有微小的影响。高鸡群周转率显著降低近交。尽管生产能力低,小规模农民还是更喜欢本地鸡(排名 1.47)而不是商业鸡(排名 1.61)。对于公鸡,农民重视繁殖力和生长性状,而对于母鸡,他们更看重母性本能和产蛋性能。与高地相比,低地的鸡蛋储存期更长(t=2.677,df=117,p=0.009,95%CI:-3.7607,-0.5622)。

结论

本研究记录了小规模农民的智慧,并鼓励将他们的见解纳入可持续的遗传改良计划。
