Livestock feed resources used as alternatives during feed shortages and their impact on the environment and ruminant performance in West Africa: a systematic review.

Ruminant feed is a major problem for the livestock sector in West African developing countries causing animal nutritional diseases, reducing ruminant production, and creating a massive ecological crisis through greenhouse gas emissions. Alternative feeds, which include agro-industrial by-products, fodder trees, crop residues, insects, fodder legumes, algae, and pulses, constitute enormous feed resources for livestock in Africa. This study was conducted in accordance with the methodological recommendations of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). We conducted a literature search using Google Scholar, Web of Science, and Scopus to identify documents related to alternative ruminant feeds using the following keywords: alternative feeds, ruminant products, environmental impacts, and West Africa. Those that met the inclusion criteria were included, resulting in 44 articles published between 2013 and 2023. These studies included 45 alternative feeds divided into six groups, including agro-industrial by-products (48.89%), followed by fodder trees (17.78%), crop residues (13.33%), insects (8.89%), fodder legumes (6.67%) and seaweeds (4.44%). Our results revealed that alternative feed resources and their effects on ruminant's performances and environment are poorly known in West Africa, which limits their inclusion in rations and sometimes leads to their misuse. Future research should focus on these aspects in order to make efficient use of these resources to improve ruminant milk and meat production.

Analysis of the interrelationships of stakeholders involved in the management of transhumance in southern Benin.

The management of pastoral mobility is a stakeholder-centered approach for the integration of resource conservation and agricultural development. This study aimed to characterize the stakeholders of transhumance and to analyze their influence in the municipality of Djidja in southern Benin. For this purpose, semi-structured interviews were conducted with 300 stakeholders involved in transhumance and pastoral resource management. The Likert scale (1 to 5) was used to assess the levels of influence and focus groups were conducted. The results showed that several stakeholders (transhumant herders, agro-pastoralists, farmers, hunters, fishermen, loggers, gendarmerie, Garso, CTAF, cattle farmers' associations, farmers' associations, SCDA, and communal transhumance committee) were involved in transhumance with diverse interests, backgrounds, knowledge, and power (P < 0.05). More than half of the farmers (72%) blame transhumant herders whose practices are source of multiple conflicts among (please mention what kind of conflicts and with whom by providing example). Statistical analysis indicated a strong influence with significant differences (P < 0.001) in the pastoral resources by four stakeholders including the communal transhumance committee, the association of herders, the Garso (scout and intermediary for transhumant herders), and the transhumant herder. This research demonstrates how the systematic analysis of the activities carried out by the stakeholders, the interconnected activities between them, and their relationships can offer insights for a better coordination of transhumance. For effective pastoral management, it is therefore important to build a dialogue between the different stakeholders involved in transhumance in southern Benin.

Towards community-based in situ conservation strategies: a typological analysis of Borgou cattle herding systems in northeastern Benin.

A thorough knowledge of cattle herding systems is very important for planning sustainable genetic improvement and conservation strategies. This paper is initiated to characterize Benin native Borgou cattle farming systems in its department of origin by mean of survey including 180 cattle farmers owning at least one phenotype of that breed. Using multiple correspondence analysis and hierarchical ascending classification, four groups of Borgou cattle farms have been identified. The first group qualified as "semi-intensive purebred Borgou cattle farming" own high numbers (87.2 ± 3.95 heads) purchased and reared with the view to promote its genetic improvement, its production, and its conservation as Benin animal genetic resource. The second group (sedentary purebred Borgou cattle farming) is represented by Bariba ethnic group with small numbers (22.18 ± 0.71 heads) of purebred Borgou cattle used mainly for draught. Cattle farmers of the third group are "large transhumant of Zebu and Borgou crossbred cattle farmers" represented by Fulani and Gando ethnic groups whose herds are generally composed of high numbers (75.20 ± 3.43 heads) of cattle acquired by purchasing, inheriting, and fostering. The last one is the "small transhumant of Zebu and Borgou crossbred cattle farming" with an average herd size of 31.98 ± 0.72 heads. Cattle farming is their main activity and animals are used for the production of milk and cheese. These distinctions between Borgou cattle farmers can be an anchorage point for designing sustainable community-based in situ conservation strategies for safeguarding this local breed in its original cradle.
