This study was carried out to evaluate muscle characteristics, meat tenderness and nutritional qualities ofBenin indigenous cattle raised on natural pasture. Thus, 10 Zebu Fulani, 10 Borgou and 5 Lagunaire wereslaughteredat 5 years old and theirLongissimus thoracismuscle samples were collected for analyses. Lactatedehydrogenase activityof Zebu Fulani was higher (p<0.05) than that of Lagunaire (3494vs2813 μmol/min/gprotein) while that of Borgou was not significantly different from those of the two other breeds (p>0.05). As forisocitrate dehydrogenase, citrate synthase, cytochrome oxidase and phosphofructokinase, no significant differencewas observed between the three breeds (p>0.05). By contrast, the total collagen content of Borgou (5.2 mg OH-proline/mg dry matter) was higher (p<0.01) than those of Zebu Fulani (3.1 mg OH-proline/mg dry matter) andLagunaire (3.2 mg OH-proline/mg dry matter). Themyosin heavy chain isoforms I, IIa and IIxwere not differentbetween the three breeds. The dry matter, the crude protein and the ether extract percentagewere not significantlyvaried from one breed to another.Branched-chain Fatty Acids andsaturated fattyacids contents were identical inLagunaire and Borgou (p>0.05) while the Zebu Fulani had the highest values (p<0.05). The ratio n-6 to n-3fattyacidsobtained in the Zebu was the lower. In general, according to the fatty acids profile, Borgou and Lagunairebulls’ meat is better than that of Zebu for heart disease.
