The aim of this study was to explore local strategies used by poultry farmers in the Extreme-Nord region of Cameroon to mitigate the effects of heat stress in hens. To this end, a survey was carried out among 390 farmers in the Departments of Diamaré, Mayo-Danay and Mayo-Kani. A total of 19 strategies for combating heat stress were identified. The main ones were the use of canary to cool the water (15.63%), Adansonia digitata fruit pulp (8.46%), Allium cepa light violet or Allium cepa dark violet bulb (6.97%), traditional salts of Sorghum bicolor or Zea mays (5.97%), Salanum macrocarpon or Salanum aethiopicum fruit (5.92%) in chicken water. The phytochemical study of these plants showed that total polyphenol and tannin contents were highest in the fruit pulp of Adansonia digitata, Salanum aethiopicum and dark purple Allium cepa bulb. However, flavonoid, saponin and vitamin C levels were highest in Salanum macrocarpon fruit. Adansonia digitata fruit pulp and Sorghum bicolor traditional salts showed higher Zn, Fe and Cu contents (p < 0.05). The antioxidant powers of Adansonia digitata, Allium cepa light violet and Salanum aethiopicum were higher. We can conclude from the strategies explored that Adansonia digitata fruit pulp and Sorghum bicolor traditional salt have the best antioxidant potential.
