To know the physicochemical composition of the raw materials mostly used in the formulation of
poultry feed.
Methodology and Results: A prospective study was carried out to identify the most commonly used feed
materials for poultry feed in Burkina Faso. The main constituents were determined by AOAC methods. Amino
acids and minerals were determined respectively by chromatography and flame spectrometry. Resultsshowed mass proportions (g / 100g DM) between 9.17 ± 0.13 and 59.9 ± 0.27 for proteins, 2.24 ± 0.10 and
15.56 ± 0.03 for lipids, 4.16 ± 0.04 and 73.8 ± 0.07 for total carbohydrates, 6.04 ± 0.13 and 14.53 ± 0.07 for
cellulose, 0.01 ± 0.00 and 34.03 ± 0.07 for calcium, 0.02 ± 0.07 and 18.01 ± 0.00 for phosphorus. Content
in essential amino acids such as methionine, lysine, and threonine ranged between 0.19 ± 0.02 and 1.49 ±
0.03, 0.25 ± 0.06 and 2.38 ± 0.03, and 0.30 ± 0.03 and 2.32 ± 0.03, respectively.
Conclusion and application of results: It emerges from this study that fishmeal has the highest contents of
protein (59.9 ± 0.27 g/100g), calcium (6.42 ± 0.04 g/100g) and phosphorus (3.88 ± 0.06 g/100g). Soy is the
richest in fat (17.98 ± 0.10 g/100g) and yellow corn is the richest in carbohydrate (73.8 ± 0.07 g/100g). These
data produced can be used to establish composition tables for local raw materials that can be used in poultry
feed and their popularization with poultry farmers will allow them to better orient themselves in the choice of
ingredients with high nutritional values and reduce the cost of formulation
