Abstract

This research was conducted at Itapetininga (23º35’30’’S , 48º03’11’’W), in order to select some tropical grasses for sheep production, twelve different plots of tropical grasses were established in randomized blocks with four replications. Each replication, isolated with fence, constituted one strip for application of grazing with ewes in a rotational system in the experimental paddock. Each grazing period was brought to an end when stolon grass more acceptable it arrived 5.5 cm and turf grass more acceptable it arrived 11.5 cm of mean height. The period one (January, 19 to March, 4), with temperature mean of 22.6ºC and pluvial precipitation of 340.6 mm, the grasses Grama paulista (Cynodon C. dactylon) and Aruana (Panicum maximum) denoted higher acceptable (P<0.05). In the period two (April, 12 to July, 01), with temperature mean of 18.5ºC and pluvial precipitation of 138.8 mm, the grasses that denoted higher acceptable were Estrela Porto Rico (Cynodon nlenfuensis), Green panic (Panicum maximum), Aruana, Hemartria (Hemarthria altissima) and Coast cross (Cynodon dactylon) (P<0.05). Hemartria showed more persistency to the grazing. In the last period (September, 28 to December 24), with temperature mean of 23.1ºC and pluvial precipitation of 268.3 mm, Estrela Porto Rico, Hemartria, Diversinervis (Digitaria decumbens), Coast cross and Aruana showed higher acceptable (P<0.05). Hemartria showed more persistence to the grazing. Hemartria, Aruana and Coast cross showed better viability to the sheep production.
