Preliminary study of pasture grasses in the Orinoco Delta. 2. Acceptability to the grazing animal.
15 grass species were established in small plots (4 X 2 m) in Dec. 1969, cut to 5 cm high on 20 Apr. 1970 and after 20 days regrowth, height and DM content were measured and acceptability to cattle determined by the time 2 cows spent grazing individual plots. Plots were cut to 5 cm high and the grazing repeated at 30, 40, 50 and 60 days. Rainfall was the greatest factor affecting height and DM content. The most palatable species were Digitaria decumbens and D. pentzii and the least palatable Brachiaria ruziziensis and B. decumbens. Palatability was also high in Echinochloa pyramidalis, especially at the early growth stages.
