Description
The increment of winter forage availability using short-rotation pastures could be an interesting way to increase winter carrying capacity. The producer could make good use of higher spring grass production. Sowing oats, rye or chicory alone is quite common in the Argentine Pampa. to evaluate the efficiency of these short-rotation winter pastures a 3 year trial was carried out at Pergamino Experiment Station. The treatments were: a) perennial pastures, 100% of the surface, b) perennial pastures 75%, and chicory-clover 25%, with 2 replications of 3 ha each. The pastures were, for. class II soils, fescue (Festrlca aru11dinacea Schreb.) cv. El Palenque MAG, 9 kg/ha, brome (Bromus unlo/oides H.B.K.) cv. Martin Fierro, 6 kg/ha, alfalfa (Medicago saliva L.) cv. Bordenave INTA, 8 kg/ha and white clover (Trifolium repens L.) cv. El Lucero MAG, 0.25 kg/ha; for class lll soils: fescue and red clover and white clover in the same amount. Each treatment had the same amount of similar soils. For temporary short-rotation pastures, chicory ( Cichorir,m i11rybus L.) cv. San Pedro, 5 kg/ha, oats (Avena saliva L.) cv. Suregrain, 30 kg/ha and red clover (Trifolir11n prale11se L.) cv. El Suref\o, 2 kg/ha were sown. Oats disappeared after the first winter pasture utilisation, but chicory and red clover remained. Each replication was divided into four paddocks for grazing, The design was a randomised one and the statistical analysis used was means comparison.

Comparison of Animal Gains Using Perennial Pastures Exclusively or Combined with Chicory-Oats-Clover Temporary Winter Pastures
The increment of winter forage availability using short-rotation pastures could be an interesting way to increase winter carrying capacity.
