Bromatological and histological features of native African grasses under grazing in Brazilian semi-arid rangelands

This study evaluated the bromatological and histological features of native African grasses under grazing in Brazilian semi-arid rangelands. An experimental grid design was used a randomised sampling method for four replicate samples three grasses. The were: Cenchrus ciliaris L., Digitaria pentzii Stent. Megathyrsus maximus (Jacq.). traits analysed included dry matter (DM), crude protein (CP), neutral detergent fibre corrected to ashes (NDFap), lignin, mesophyll, vascular bundle, phloem, xylem, sheath, sclerenchyma, bulliform cells, adaxial abaxial epidermis. type grass cycle correlated with DM, NDF lignin (p < 0.05), whereas CP not affected by these factors > 0.05). Dry ranged between 128 304 g kg−1; 90 167 NDFap 542 707 kg−1, 10 40 kg−1. proportion xylem (8.4%), sheath (30.5%) total bundles (38.1%) were greater M. percentage sclerenchyma did differ species C. had mesophyll than Of analysed. exhibited highest forage quality, because it lowest concentration lower proportions lignified tissues.
