Water balance was calculated Thornthwaite and Mather, using the average temperature and accumulated monthly rainfall Figure 2. However, except for the first dry season, because of the low herbage accumulation rate Table 2 and the small dimensions of the paddocks 0.
Standard errors of the mean are indicated between parentheses. Thus, Brachiaria brizantha cv.

Together with high temperatures Figure 1these conditions resulted in a water deficit that lasted until the beginning of December, whereas in the following year, the soil water level was re-established in the beginning of October Figure 2. 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.
The eight accessions that were best in the combined analysis of all tested locations Valle et al. Variations in the grazing process, pasture accessibility, and ease of the leaf harvest resulting from changes in canopy structure may therefore significantly influence forage consumption and, consequently, animal performance.

Introduction One of the factors responsible for low beef cattle production in the tropics is inadequate animal nutrition, resulting mainly from the seasonality of forage production, which is characteristic of tropical regions. Proceedings of the 19th International Grassland Congress. Communications in Statistics – Simulation and Computation However, it was also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in the calculation of HA.
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.
ABSTRACT The objective of the present study was to evaluate live weight gain per animal and per area and its relationship with the characteristics grizantha pastures of Brachiaria brizantha cv. Nineteen selected accessions of Brachiaria brizantha were evaluated brachixria a Regional Assay Network.
Composite samples were obtained by combining five sub-samples and separated into leaf leaf bladestem stem and sheathand dead material; the percentage of the total weight for each component was determined. John Wiley, New York. No differences between the two cultivars were observed during the wet season for any of the evaluated parameters. The animals were treated with a wide spectrum vermifuge at the beginning of the experiment and with pour-on ectocide during the experiment as needed for the control of ticks and horn flies.
A third ecotype, registered as cv. Therefore, any effort to increase the availability of quality forage during the dry season will contribute significantly to increasing cattle farming productivity. Pasture samples were collected once a month, and herbage accumulation rate HARpercentage of leaves PLleaf: Three steers were placed in each paddock, in a total of 36 steers.

Brizanfha experiment was conducted between June and May Crop Breeding and Applied Biotechnology The samples were divided into two sub-samples.
Therefore, it was decided to reduce the stocking rate per paddock during the second and third dry seasons Table 2. In May, fences were built, and drinking troughs were installed. Modelling covariance structure in the analysis of repeated measures data. The height at each point was considered to be the average bizantha height surrounding the ruler.

Average daily gain ADG was analyzed using multivariate repeated measures analysis according to Littell et al. This finding is in accordance with those described by Carvalho et al. In spite of the adjustment of the stocking rate Table 2 and Figure 3pasture height Table 1 and herbage mass Table 4 still decreased, during that season. The seeds were covered by using a locked disk harrow, and soil was compacted using a soil compaction roller.
The lower performance observed in the present study cannot be attributed to the herbage nutritive value because the average percentages of CP and IVOMD 8.
Herbage accumulation rate plata higher for the third than for the second experimental year, and HM was lower for the second than for the remaining experimental years. 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.
