Proceedings of the 19th International Grassland Congress. These brizsntha suggest that this cultivar might be a new alternative to be used under different production systems, mainly during the dry period, which represents the main constraint as far as feed availability and quality are concerned.

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.

Covariance structure selection in general mixed models.

For the stratified herbage samples, the same model was applied, but the effect of the strata was added and considered fixed.

Tester and “grazer” animals were weighed monthly following a h fast. The use of improved forage plants may help mitigate this problem. July 30, ; Accepted: Decreased bite depth is commonly associated with increased time per bite, decreased bite rate Palhano et al.


Laboratory of Climatology, New Jersey. A completely randomized blocks experimental design was used, brachiafia two treatments and six replicates. The herbage allowance Allen et al. Following each harvest, the cages were placed at other points within the paddock according to the same method. 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.

Sward heights were measured once a week, and the stocking rate SR was adjusted using regulator steers to maintain the sward height at 30 brachiari. The data indicate that herbage allowance did not limit forage ingestion and consequently live weight gain, during the dry season Table 4. 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.

Based on previous analyses, the highest-order polynomial was selected. A randomized blocks experimental design was used, with two treatments and six replicates.

The soil was corrected with application of 2. Animals were weighed every 28 days. The soil water storage capacity used was 75 mm. Communications in Statistics – Simulation and Computation Soil chemical characteristics were as follows: The eight accessions that were best in the combined analysis of all tested locations Valle et al.


As a result of its higher regrowth, cv. However, in the study conducted by Euclides et al. 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, studies on the value for cultivation and use of this new cultivar, which provide adequate and reliable information on the new oiata material to its users, are needed before it is placed on the market MAPA, Three steers were placed in each paddock, in a total of 36 steers.

The animals remained in the same paddocks for one year as tester animals, when they were replaced with other animals of the same category. The steers were distributed according to weight so that the average weight in each paddock was the same.

In February4. The grazing method used was continuous stocking, with variable stocking rate.
