Resumo -Para uma pecuária precoce e racional eficiente tem-se que, alcançar o equilíbrio biológico entre o valor forrageiro da planta, ou das plantas que compõem a pastagem, e do tipo de animal, para assim assegurar tanto a produtividade como a sustentabilidade do sistema. Assim o continuo ajuste entre as necessidades energéticas e protéicas de bovinos e a oferta de nutrientes através da pastagem e Ood bovinosrto. uplementaçorna essencialconfusa, seria melhor desta maneira: Assim o continuo ajuste entre a demanda e a fo uso estratégico de suplementação se torna essencial na pecuária de ciclo curto. Isto se consegue com um bom manejo das pastagens e o uso estratégico de suplemento. Partindo disto, esta revisão de literatura vem a objetivar fornecer informações sobre a bovinocultura de ciclo curto em pastagem. Palavras chaves -Bovino. Desempenho. Precoce. Pastejo.Abstract -For efficient early and rational livestock one has to achieve biological balance between forage value of the plant, or plants that make up the pasture, and the type of animal, thus ensuring both productivity and sustainability of the system. Thus the continuous adjustment between energy and protein requirements of cattle and nutrient supply through grassland and strategic supplementation use becomes essential in the short-cycle livestock. This is achieved with a good pasture management and the strategic use of supplement. From this, this literature review is to objectify provide information on the cattle grazing in short cycle.

“…In Brazil, pastures are the main, less costly forage resource used for ruminant production due to lower investment in facilities and equipments and the lowest expenditure with labor, inputs etc. (Maixner et al, 2009;Soriano et al, 2013).…”

Intercropping with cool season species has been used as an alternative to increase productivity off-season (fall/winter) of irrigated pastures. This study was conducted from May to October 2009 in Icaraíma, Paraná State, to evaluate the productivity and morphological composition of the Tifton 85 grass overseeded with winter forage in irrigated system. The experiment was a randomized block design with four replicates and repeated measures over time. The experimental plots consisted of five treatments, three as oats overseeding using the genotypes IAPAR 61, IPR 126, and FMS2 on Tifton 85 pasture and one as overseeding of oats combined with rye (IPR 126 + IPR 89) also on Tifton 85 grass and, finally, a control with only Tifton 85 without overseeding. The overseeding of IPR 126 oats achieved the highest cumulative productivity, 4102 kg DM ha-1 , with leaf/stem ratio higher than that of exclusive Tifton 85 exclusive, 1.77 and 1.08, respectively. However, overseeding of winter forages did not increase the overall productivity of the pasture.

“…The obtained results also showed that the grazing strategies resulted in rest periods for the Florico grass. Several authors have reported the rest period of this genus to be approximately 27 to 30 days (Vilela et al, 2005;Costa et al, 2013;Soriano et al, 2013), using other grazing strategies such as fixed resting interval and canopy height.…”

The objective of this work was to evaluate the variations in root dry matter mass (RDM) and the percentage distribution (PD) of the root density of Florico grass (Cynodon nlemfuensis) in the 0-40-cm soil layer, when managed under different grazing strategies. Two defoliation frequencies (90 and 95% light interception, as the criterion for allowing animals in the paddock) and two defoliation severities (post-grazing heights of 20 or 30 cm) were assessed. Four seasonal evaluations of the root system were performed between the winter of 2012 and the autumn of 2013, using the monolith and trench excavation technique, collecting 1-dm3 samples from soil surface down to a depth of 40 cm, in four sequential extracts of 10 cm each. Lower RDM values (0.69 g dm-3) were obtained in winter, with the four grazing strategies, whereas higher values were observed in spring (1.64 g dm-3), for the 30-cm post-grazing residue, and in autumn (1.63 g dm-3) for the 20 cm post-grazing residue, regardless of the light interception value. Between 52 and 66% of the RDM density was observed in the 10-cm layer, for all four grazing strategies, in all seasons.
