Brachiaria Brizantha CV. BRS Piatã
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. Three piiata were placed in each brachixria, in brachiaris total of 36 steers.
However, studies on the value for cultivation and use of this new cultivar, which provide adequate and reliable information on the new genetic material to its users, are needed before it is placed on the market MAPA, Daily average weight gain was calculated as the increase in live weight of tester animals divided by the number of days between weighing sessions.
The seeds were covered by using a locked disk harrow, and soil was compacted using a soil compaction roller. AU – animal unit. A completely randomized blocks experimental design was used, with two treatments and six replicates.
Therefore, the unfavorable canopy structure for grazing and the lower nutritive value of the forage explain the lower animal performance observed in the dry than in the wet season Table 2.
Nineteen selected accessions of Brachiaria brizantha were evaluated in a Regional Assay Network. bracyiaria
Stapf, Brachiaria decumbens Stapf, Brachiaria ruziziensis R. Variations in the grazing process, pasture accessibility, and ease piara the leaf harvest resulting from changes in canopy structure may therefore significantly influence forage consumption and, consequently, animal performance.
The objective of the present study was to evaluate live weight gain per animal and per area and its relationship with the characteristics of pastures of Brachiaria brizantha cv.
Standard errors of the mean are indicated between parentheses. An international terminology for grazing lands and grazing brachoaria. 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.
Grass and Forage Science Therefore, the canopy structure brizanths in the present study likely led to decreased animal nutrient intake, resulting in a lower ADG.
However, except for the first dry season, because of the low herbage accumulation rate Table 2 and the small dimensions of the paddocks 0. The use of improved forage plants may help mitigate this problem. Before pasture establishment, soil samples were collected from the cm layer.
The experimental area was 8. Herbage accumulation was estimated using three exclusion cages 1 m 2 for each paddock. A randomized blocks experimental design was used, with two treatments and six replicates. Live weight gain per area was calculated as the product of the average daily live weight gain of tester animals and the total number of animals tester and grazer per paddock and grazing cycle.

Every 28 days, 15 samples 1 m 2 were randomly selected and harvested at ground level in each paddock. ABSTRACT The objective of the present study was to evaluate live weight gain per animal and brachiafia area and its relationship with the characteristics of pastures of Brachiaria brizantha cv.
Stocking rate and live weight gain per area were higher for the first year, lower for the second year, and intermediate for the third year.
This finding is in accordance with those described by Carvalho et al. This finding is of great importance because the seasonality of forage production is one of the bottlenecks for pasture-raised cattle production.

Embrapa Gado de Corte, Campo Grande. Covariance structure brachiatia in general mixed models. How to cite this article. The eight accessions that were best in the combined analysis of all tested locations Valle et al. The percentages of each component were used to estimate the leaf: These characteristics are of great importance because diet selection is the main factor affecting the nutritional status of animals Walker, Tester and “grazer” animals were weighed monthly following a h fast.
Because of a delay in the building of the exclusion cages, herbage accumulation was not estimated for the first experimental year.

The soil was corrected with application of 2. Every 28 days, the cages were placed in points representative of the average canopy height, with similar mass and morphological composition to the areas under grazing.
Therefore, any effort to increase the availability of quality forage during the dry season will contribute significantly to increasing cattle farming productivity.
Soil chemical characteristics were as follows: O melhoramento de forrageiras tropicais no Brasil. Services on Demand Journal. John Wiley, New York. The data indicate that herbage allowance did not limit forage ingestion and consequently live weight gain, during the dry season Table 4.
As a result of its higher regrowth, cv. However, the seasonality of forage production will still be a limitation present in all scenarios Deconto,requiring new strategies to meet the animal nutritional demands for the longest period possible. Decreased bite depth is commonly associated with increased time per bite, decreased bite rate Palhano et al.
Conclusions Brachiaria brizantha cv. These traits suggest that this cultivar might be a new alternative brachiarix 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 brachiwria only observed in June Figure 2.
The sward height was measured twice a week at 60 random points per experimental unit, using a ruler graduated in centimeters. Sward heights were measured once a week, and the stocking rate SR was adjusted using regulator steers to maintain the sward height at 30 cm.
