In the southern region of Brazil, the annual cold season grasses are an alternative for forage production
to supply the animals? food deficiency in autumn-winter. Annual ryegrass (Lolium multiflorum) c can be
considered as the most important forage for the agricultural context of this region. Tetraploid ryegrass plants
have broader leaves, high total forage mass production, longer vegetative cycle, and greater ratio between
content and cell wall, raising the larger cell size levels of soluble carbohydrates, proteins and lipids. In recent
years, new ryegrass cultivars have been made available on the market, however information on the productive
cycle and animal performance of these materials is scarce. The objective of this study was to evaluate the
productive cycle of tetraploid annual ryegrass, under rotational grazing, as well as the performance of male
and female growing beef cattle. The trial was carried out for two consecutive years by planting annual ryegrass
(cultivar Winter Star) in an area of 4 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.
Fourteen crossbred cattle (seven male; seven female; mean live-weight: 250 kg; aged approximately 8 months
on Day 0) were used for the experiment. 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%. In
both years of experiment it was realized five grazing periods. The total dry matter production was higher in
the second year when compared to the first year of the trial (6718.2 and 4555.2 kg of DM ha-1, respectively;
P<0.05) consequently, higher dry matter production allowed greater gain per area. In the first year of the
experiment the average stocking rate was 2.2 AU ha-1 with similar daily weight gain between males and
females (855.8 g animal-1), accumulating a live weight gain per hectare of 530.8 kg in 158 days. In the second
year the mean stocking rate was 3.6 AU ha-1 with daily weight gain of 0.99 kg animal-1 for males and 0.82
kg animal- 1 for females (P<0.05), totalizing a live weight gain per hectare of 666.4 kg in 152 days. The
results demonstrate that the cultivation of winter grasses, such as the tetraploid ryegrass Winter Star, provides
adequate weight gain for males that will be destined to slaughter and growth for heifers intended for breeding,
increasing productivity in a critical period of the year in the southern region of Brazil. MenosIn the southern region of Brazil, the annual cold season grasses are an alternative for forage production
