Feeding dairy cows during the dry season is still a bottle nec for milk production in Burkina Faso and farmers use their indigenous knowledges for improvement. The research question is how to ¶The better handle thoses indigenous knowledges by improving methodologically the making process of galactagogues blocks which could be used as supplementary feed for lactating cows. The objective was to make two galactagogue blocks, one contains small millet and monkey’s bread (called BAMPS) and the other one, Vigna unguiculata (Soy bean) and Euphorbia hirta (called GALACTO) to increase dairy cows milk syhthesis. The method has been to collect forage and concentrate ingredients in urban and peri-urban area of Ouagadougou in 2023. Samples were run for chemical analysis, total proteins and carbohydrates contents. At the same time, total coliform and toxicity test of aflatoxines were also done on the initial solutions in 2024. Samples were all free from total aflatoxines and aflatoxines B1 in 2024. The total bacteria count was 10 UFC/g Adansonia digitata’s powder and 2.1x105 UFC/g, 4.6x104 UFC/g, 3.3x104 UFC/g for Vigna unguiculata, Pennissetum glaucum and Euphorbia hirta (whole plant), respectively. The data were subjected to descriptives statistics using Excel 2016. The previous results contributed to produce square dries galactogogues of 100, 200, 300 and 400 grammes (made june 2024). Zea mays bran was used as support-structure in the current experimental conditions. The results showed good hardness by pressing with thumb and consistance under full hand-pressure. BAMPS was a white-dirt colour with Zea mays smell. GALACTO was clear-green colour with Vigna unguiculata smell. It could be concluded that, it is technical possible to make galactogogues blocks from above animal feed ingredients for feeding system in Burkina Faso. The hypothesis of the current study was verified and the objective met for the upcoming experimental test on animal.
