[en] 1. An experiment was carried out with 120 helmeted guinea
fowls during one year in Parakou (Benin). Feed intake,
ingredient and chemical composition, along with the nutritional
adequacy of scavenging diets were measured during the rainy
season (November-February) and dry season (March-October) in
order to propose supplementation strategies. Ingredients found
in crops were identified and allocated into 6 main categories
(supplemental feed, seeds, green forages, animal materials,
mineral matter and unidentified materials). 2. Mean dry weights
of crop contents were significantly higher in the rainy than in
the dry season. Amounts and proportions of supplemental feed and
seeds were not significantly different between seasons, whereas
those of green forage, animal materials and mineral matter were
higher in rainy season. Supplemental feed, especially maize and
sorghum, was the largest component of the crop content in both
seasons. The most represented grass seeds were Panicum maximum
(rainy season) and Rottbo
