This study proposed to assess forage productivities to allow an appropriate mowing period determination in their use as dairy female feed in Madagascar. A test on small plots has been set up in the southern part of the capital city Antananarivo during one dry period （4 months）. Live observations followed by laboratory proximate analyses have been performed for forage productivity and feeding value determination. Cultivated on tanety （hill）, irrigated in counter season, results show that： （I） oat higher height （H = 96.7 cm） than Italian ray grass （H= 69.4 cm） at 99 days of age; （2） similar biomass productivity; （3） dry matter yields significantly different （p = 0.05）; （4） certain similarity between dry matter yields and FMU （fodder milk unit） score evolution; （5） leafy stage of Italian ray grasses at 99 days of age; （6） mid-flowering stage for oats during the same period. Cell wall content, crude fiber and dry matter contents increased with age （p = 0.05）. Crude proteins and minerals evolved in opposite directions. Gross energy content did not present precise variation with age. This study allowed that for an acceptable quantitative and qualitative production during dry seasons, good mowing period for Italian ray grass could start at 76 days age, while oat could start being harvested at 68 days.展开更多
