||Objective: This study aimed to make an inventory of animal diseases that affect milk production and the plants locally used against these diseases.
Materials and methods: A survey was carried out from April to August 2013 in 41 farms in department of Collines, 40 in Alibori, 40 in Borgou and 21 in Mono using questionnaires. SAS software was used with Chi-square test and bilateral Z test.
Results: The study revealed twelve main pathologies that limit milk production. Among these pathologies, foot-and-mouth disease and trypanosomiasis were the most mentioned pathologies. To fight these pathologies, 60 medicinal plants of 32 families were recorded. The most cited families were Leguminosae (31.67%), Combretaceae (6.67%), Meliaceae (5%) and Rubiaceae (5%), whereas the predominant species used by animal keepers were Khaya senagalensis, Vitellaria paradoxa, Parkia
biglobosa and Securidaca longipedunculata. The 60 listed species were used in 85 recipes which varied from one department and farmer to another. The most used
organs were plant barks (41.06%) and roots (31.13%), while the most common methods of preparation were decoction (37.5%), maceration (32.5%) and
powders (22.5%). Oral route was the main route of administration.
Conclusion: The inventory has shown that the important pathologies are footand-mouth disease and trypanosomiasis. This needs immediate actions. Barks and
roots were the commonly employed plant organs used as infusion (decoction and maceration) and powder that farmers administer orally to animals. The harvest did
not require a special season or time. Furthermore, farmers inherited most of these recipes from their parents and they use them because of their effectiveness
