The use of improved forage plants may help mitigate this problem. However, in the study conducted by Euclides et al. Crop Breeding and Applied Biotechnology A third ecotype, registered as cv.

Thus, Brachiaria brizantha cv. Communications in Statistics – Simulation and Computation Laboratory of Climatology, New Jersey. This finding is in accordance with those described by Carvalho et al. A completely randomized blocks experimental design was used, with two treatments and six replicates. The experimental unit for both vegetation and animal data was the paddock. However, differences between experimental btachiaria were observed for the remaining variables quantified Table 5.

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 briizantha wet season Table 2.

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.

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

The percentages of each component were used to estimate the leaf: Evaluation of Brachiaria brizantha ecotypes under grazing in small plots. The eight accessions that were best in the combined analysis of all tested locations Valle et al. 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.

It should be highlighted that a part of the decrease between the first and the second year may be attributed to climate conditions, as discussed above. Tester and “grazer” animals were weighed monthly following a h fast.

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. 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 ppiata organic matter digestibility, by near-infrared spectroscopy NIRS.

Animals were weighed every 28 days. The soil at the experimental area is a Dystrophic Red Latosol Embrapa, 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. 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: Proceedings of the 19th International Grassland Congress. The stocking rate was calculated as the product of the average weight of tester and “grazer” animals and the number of days the animals remained in the paddock.

The sward height was measured twice brachixria week at 60 random points per experimental unit, using a ruler graduated in centimeters. The grazing method used brachiarla continuous stocking, with a variable stocking rate.

No differences between the two cultivars were observed during the wet season for any of the evaluated parameters. However, it was also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in brisantha calculation of HA. 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.

Average daily gain ADG was analyzed using multivariate repeated measures analysis according to Littell et al. Therefore, any effort to increase the availability of quality forage during the dry season will contribute significantly to increasing cattle farming brizanta.

In spite of the great effort of research institutions for the release of new cultivars, the number of cultivars effectively used is still small, and these few cultivars occupy large areas, generating vulnerability in the production systems due to biotic and abiotic factors Valle et al.

The soil water storage capacity used was 75 mm. 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 Journal of Agricultural Science
