Abstract

BACKGROUND

Adequate feeding is essential to realizing the potential of small ruminants to alleviate poverty among smallholder farmers. This study was conducted in two villages in the Ejura-Sekyedumase District of Ghana and was motivated by farmers' non-adoption of modern feed technologies, but more importantly by the need to understand the small ruminant feed system considering farmers' different socio-economic backgrounds and how these relate to small ruminant performance. In this study, the feed system was defined as the type, source and seasonality of feeds and how small ruminants access them.

METHODS

Qualitative and quantitative methods were used to allow for triangulation. Data were collected in seven stages comprising key informant interviews, a census, a cultural domain study, botanical specimen collection and identification, focus group discussions, a household survey, and a small ruminant performance study.

RESULTS

Farmers listed 175 items that are used as small ruminant feed and salience indexes were calculated. There was high consensus about the domain of small ruminant feeds, with 15 items comprising the consensus model. Respondent agreement scores correlated positively with age and negatively with list length. Respondents from matrilineal lineages had higher agreement scores than those from patrilineal lineages. Natural pasture and wild browse scored high in pair wise ranking by village and sex groups. Of the 33 feeds that farmers fed to goats, maize grains, cassava peels and Margaritaria discoidea were the most salient. Six major feed system groups based on access were identified at household level, which regrouped into three at village level based on feed type and source. Patrilineal households were more likely to tether their livestock. Significant differences were found between some socio-economic groups for pre-weaning average daily gain (ADG) of kids, but not for prolificacy of does.

CONCLUSIONS

The need for nutritive and agronomic investigations into major feeds, the creation of non-cropping zones around village fringes and studies on labour demands of different feed systems are proposed. The insight gained in this study on farmers' perceptions and practices relating to small ruminant feeds could guide in the selection and introduction of feed innovations that fit into current feed systems to enhance adoption.

摘要

背景

为了充分发挥小反刍动物在减轻小农户贫困方面的潜力,充足的喂养至关重要。本研究在加纳埃朱拉-塞克亚杜马塞区的两个村庄进行,其动机是农民没有采用现代饲料技术,但更重要的是,需要了解小反刍动物饲料系统,考虑到农民不同的社会经济背景以及这些背景与小反刍动物表现的关系。在本研究中,饲料系统被定义为饲料的类型、来源和季节性,以及小反刍动物如何获得这些饲料。

方法

采用定性和定量方法进行三角测量。数据分七个阶段收集,包括关键信息访谈、普查、文化领域研究、植物标本采集和鉴定、焦点小组讨论、家庭调查和小反刍动物性能研究。

结果

农民列出了 175 种用于小反刍动物的饲料,计算了显著指数。小反刍动物饲料领域的共识度很高,有 15 项构成共识模型。应答者的一致性得分与年龄呈正相关,与列表长度呈负相关。来自母系血统的应答者比来自父系血统的应答者的一致性得分更高。天然牧场和野生灌木在村庄和性别群体的两两排名中得分较高。在农民给山羊喂食的 33 种饲料中,玉米颗粒、木薯皮和 Margaritaria discoidea 是最突出的。根据获得途径,在家庭层面确定了 6 个主要的饲料系统组,根据饲料类型和来源,在村庄层面将其重新组合成 3 个组。父系家庭更有可能将他们的牲畜拴起来。在一些社会经济群体中小羊羔的断奶前平均日增重(ADG)存在显著差异,但母羊的繁殖力没有差异。

结论

建议对主要饲料进行营养和农艺调查,在村庄边缘周围建立非作物区,并研究不同饲料系统的劳动力需求。本研究中获得的关于农民对小反刍动物饲料的看法和做法的见解,可以指导选择和引入适合当前饲料系统的饲料创新,以提高采用率。
