In southern Brazil, one of the main limitations of livestock activity is the shortage of forage between autumn
and early winter. Rye (Cecale cereale) is strategic specie for the autumn and winter cultivation, because of its
precocity. It stands out for its rusticity and ability to adapt to poor soils, especially the sandy ones. The double
purpose wheat (Triticum aestivum) can be used as forage because it presents high dry matter production,
tolerance grazing or cutting and high grain yield under grazing. Considering the variability of available
materials, the evaluation of the different species is fundamental to the exploration of the potentialities of each
one of them. The objective of this work was to verify if there are differences in animal performance in pastures
formed by rye (cultivar Temprano) and double purpose wheat (cultivar Tarumã), under rotational grazing.
Each species was implanted in an area of 2 ha, subdivided into four paddocks. It was evaluated available
dry matter before animals input, residual dry matter after animals output to calculate total dry matter (DM)
production. Sixteen crossbred steers were used for performance evaluation (mean live-weight: 177 kg; aged
approximately 5 months on Day 0). The forage offer was regulated by ?put and take? system and the tester
animals were maintained in the plots for the entire period of experiment. The experimental design was
completely randomized and the data analyzed by the statistical program R with significance level of 5%.
It was realized three grazing periods for rye and wheat. The total forage production was similar between
treatments on average 5487.4 kg of DM ha-1 (P>0.05). Animal performancewas also similar among treatments,
the average daily gain was 0.89 kg animal-1. However double-purpose wheat supported higher stocking rate
(2.9 AU ha-1; P<0.05) totalizing a live weight gain per hectare of 275 kg in 70 days. Rye cultivation allowed
a mean stocking rate of 2.6 AU ha-1 totaling a live weight gain per hectare of 264.5 kg in 70 days. In this
study the use of double purpose wheat provided greater gain per area when used exclusively for grazing. The
evaluation ofthe various species available for cultivation during autumn-winter supports the diversification
and economy of rural properties in southern Brazil.
