  5. Foraging efficiency, stocking rates, grazing pressure and livestock weight changes in the Sahel por Hiernaux, Pierre H.Y., Ayantunde, Augustine A., Leeuw, P.N. de, Fernández Rivera, S., Sangare, M., Schlecht, Eva

    Publicado 1999
    “…Dry season losses were more severe under continuous grazing systems and on wetter sites and increased with increasing grazing pressure. Animal performances were not clearly related to forage use efficiency which on average was 45<+->15 percent net (32<+->12 percent gross) over the year and up to 66<+->19 percent net (38<+->21 percent gross) in the wet season.…”
