Herbage accumulation rate was calculated as the difference between forage mass inside current harvest and outside previous harvest of the cage, considering only the green part leaves and stemsdivided by the number of days between samplings.

Discussion The observed herbage accumulation rate variation Figures 3 A and 3B was typical for the tropical regions, resulting from the rainfall seasonality Figures 1 and 2 and temperature and photoperiod variations Figure 1. However, except for the first dry season, because of the low herbage accumulation rate Table 2 and the small dimensions of the paddocks 0.

During the wet season, HA was lower than the optimal value suggested by Hodgson Table 4.

Therefore, it was decided to reduce the stocking rate per paddock during the second and third dry seasons Table 2. The Akaike information criterion was used to select the covariance matrix Wolfinger, Two samples simulating animal grazing were also collected from each paddock and analyzed to determine crude protein, neutral detergent fiber, and acid detergent lignin concentrations and in vitro organic matter digestibility, by near-infrared spectroscopy NIRS.

A completely randomized blocks experimental design was used, with two treatments and six replicates. The observed herbage accumulation rate variation Figures 3 A and 3B was typical for the tropical regions, resulting from the rainfall seasonality Figures 1 and 2 and temperature and photoperiod variations Figure 1. The height at each point was considered to be the average canopy height surrounding the ruler.

The steers were distributed according to weight so that the average weight in each paddock was the same. The animals remained in the same paddocks for one year as tester animals, when they were replaced with other animals of the same category. Before pasture establishment, soil samples were collected from the cm layer. Ingestive behaviour, herbage intake and grazing efficiency of beef cattle steers on Tanzania nrizantha grass subjected to rotational stocking managements.

In February4. Proceedings of the 19th International Grassland Congress. Journal Range Management Pasture samples were collected once a month, and herbage accumulation rate HARpercentage of leaves PLleaf: Tester and “grazer” animals were weighed monthly following a h fast. The experimental area was 8.

The soil was corrected with application of 2. AU – animal unit.

The pronouncedly lower HAR for the dry season, regardless of the grass cultivar Table 2resulted mostly from the water stress observed during the dry season Figures 1 and 2.

The percentages of each component were used to estimate the leaf: Rainfall, average relative air humidity, and minimum, average, and maximum temperatures Figure 1 were collected from a meteorological station close to the experimental site. Of these accessions, two were selected and brachiarka for animal production: John Wiley, New York.


However, the higher ADG observed during the first dry season Table 5 can be explained by the better rain distribution observed for that period Figure 1given that water deficit was only observed in June Figure 2.

Grass and Forage Science Statistics in Medicine The soil at the experimental area is a Dystrophic Red Latosol Embrapa, An international terminology for grazing lands and grazing animals. Modelling covariance structure in the analysis of repeated measures data. The Journal of Agricultural Science Covariance structure selection in general mixed models. Brizanthha, it was also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in the calculation of HA.

The applied model included the random effect of the blocks and the fixed effects of the grass cultivar, experimental year, season of the year, and their interactions.

Revista Brasileira de Zootecnia The lower performance observed in the present study cannot be attributed to the herbage nutritive value because the average percentages of CP and Brachiarua 8. The remaining animals were kept at a brizzntha pasture 7.
