In Africa, a large diversity of diets (forage + staple food crop residues or other agricultural byproducts) is used by cattle herders in different production systems. It is reported that feeding strategies could help to reduce enteric methane (eCH 4 ) in ruminants by up to 55%. In order to test different feeding strategies, a trial was carried out (CIRDES, Burkina Faso) on 10 Sudanese peulh zebu steers (32 months of age) with live weight (LW) 147±5.8 kg (i.e. 0.59 Tropical Livestock Unit). Animals were kept in individual box and were fed at 3.5% LW with natural pasture and crop byproducts (75:25, DM basis). Individual eCH4 (GreenFeed system) and total tract digestibility were measured. The 6 main crop byproducts used in cattle diet were identified with a survey from farmers: legume haulm-based diets (cowpea and peanut haulms), and cereal straw-based diets (maize, sorghum, millet and rice straws). For each crop byproduct, the experiment consisted in 3 weeks, including 2 weeks of feed adaptation and 1 week of data collection. Basal diets consisted in natural forage hay (CTL hay) to test cereal crops, and Panicum maximum hay (CTL Pm) to test legume crops. Dry matter intake (DMI, g/kg LW) were on average 18.0±1.92 in cereal straw diets vs 16.4±2.06 in CTL hay; and 25.5±1.69 in legume haulm diets vs 21.7±2.29 in CTL Pm. The DM digestibility (%) were 48.1±3.01 in cereal straw diets vs 46.0±3.05 in CTL hay; and in legume haulm diets 49.8±1.4 vs 48.7±6.1 in CTL Pm. Intake content was lower in fibre for cereal straw and legume haulm diets compared to their control (NDF, g/kg DMI, 664±26.7 and 611±8.5 vs 734±13.6 and 712±14.0, respectively). Amounts of eCH4 (g/kg DMI) emitted were 26.5±6.85 in cereal straw diets vs 30.6±7.17 in CTL hay; and 24.0±4.26 in legume haulm diets vs 27.9±4.66 CTL Pm. Complementation with cereal and legume crops reduced by 13 and 21% eCH4 yield.
