Effect Of The Ewes Density Per Hectare And Day On The Cultivated Pasture In Organic Farm

In order to evaluate the effect of ewes density under a rational rotational grazing system on a cultivated pasture in an organic farm, 418 ewes were used in a very high livestock load. The experience consists of four different plots of 0.5 ha each one. Besides, there was a control area where the flock didn’t get in. Despite the different plots were cultivated using the same techniques and the same amount of seed, the plant composition was not the same. Although the ewes grazed, Bromus diandrus still growing because the animals were able to choose among the plant resources. The plant re-growth had higher protein levels than the initial situation (2,35±0,43) and lower fibre amounts (-3,70±0,73). The result was a better quality food in the re-growth than before the graze.
