In addition, the uncertainties regarding climate changes lead to different predictive strategies for breeding programs. Animals were weighed every 28 days.

The average daily gain observed for cv. 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. 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.

Hodgson suggested that herbage intake would reach its maximum at an herbage allowance of 10 to 12 kg of dry matter per kg of body weight. This is an open-access article distributed under the ipata of the Creative Commons Attribution License. Another poata that may be related to forage ingestion by animals and consequently to their performance is herbage allowance. Stapf, Brachiaria decumbens Stapf, Brachiaria ruziziensis R.

The soil was corrected with application of 2.

Embrapa Gado de Corte, Campo Grande. 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.

Evaluation of Brachiaria brizantha ecotypes under grazing in small plots. The Journal of Agricultural Science The data indicate that herbage allowance did not limit forage ingestion and consequently live weight gain, during the dry season Table 4. However, it brozantha also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in the calculation of HA.

The experiment was conducted between June and May Crop Breeding and Applied Biotechnology Daily average weight gain was calculated as the increase in live weight of tester animals divided by the number of days between weighing sessions.

Following each harvest, the cages were placed at other points within the paddock according to the same method. However, the seasonality of forage production will still be a limitation present briaantha all scenarios Deconto,requiring new strategies to meet the animal nutritional demands for the longest period possible.

A third ecotype, registered as cv. AU – animal unit.

As a result of its higher regrowth, cv. 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, Stocking rate and live weight gain per area rbachiaria higher for the first year, lower for the second year, and intermediate for the brachiarla year. The experimental area was 8.

Discussion The observed herbage accumulation rate variation Figures 3 A and 3B was typical for the tropical regions, resulting brachjaria the rainfall seasonality Figures 1 and 2 and temperature and photoperiod variations Figure 1.

The samples were divided into two sub-samples. Statistics in Medicine Ingestive behaviour, herbage intake and grazing efficiency of beef cattle steers on Tanzania guinea grass subjected to rotational stocking managements. The data were grouped according to the season of the year as follows: John Wiley, New York. Conclusions Brachiaria brizantha cv. 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.

The remaining animals were kept at a reserve pasture 7. In February4.

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. No differences brachiaia the two cultivars were observed during the wet season for any of the evaluated parameters. Grazing behaviour, herbage intake and animal performance of beef cattle heifers on marandu palisade grass subjected to intensities of continuous stocking management.

Herbage accumulation was estimated using three exclusion cages 1 m 2 for each paddock. Revista Brasileira de Zootecnia 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. A completely randomized blocks experimental design was used, with two treatments and six replicates.
