Primary, secondary production and botanical composition to native grassland improved with fescue (Festuca arundinacea), legumes and temperate grasses.

Abstract

One of the barriers for expansion on improvement of native grasslands in Santa Catarina is the low tolerance of forage to extremes climatic events, which often has damaged shoots by strong frosts or even cold winds during the winter. Some forage species has tolerance to these climatic events. The aim was to evaluate the primary and secondary production in a native grassland improved in an area of 6.5 ha, divided into 6 paddocks with introduction of fescue, white oats, annual ryegrass and rye in the fall, and soil chemical correction. Every 28 days, the animals were weighed for measuring the secondary production. The results showed an increase in pasture production, greater diversity of species in the floristic composition, a gain per area of 455.28 kg LW/ha/period of 305 days of grazing; average daily gain of 0.520 kg/head/day, with an average stocking rate of 744 kg LW/ha.
