The average daily gain observed for cv. 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.

Brachiaria Brizantha cv BRS Piatã

The percentages of each component were used to estimate the leaf: July 30, ; Accepted: Revista Brasileira de Zootecnia These characteristics are of great importance because diet selection is the main factor affecting the nutritional status of animals Walker, Herbage inside and outside of the cages was harvested at the ground level and sampled as described above; then, herbage mass was determined.

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.

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. Tester and “grazer” animals were weighed monthly following a h fast.

AU – animal unit. The soil water storage capacity used was 75 mm.

Because of a delay in the building of the exclusion cages, herbage accumulation was not estimated for the first experimental year. Services on Demand Journal. A third ecotype, registered as cv. During the wet season, HA was lower than the optimal value suggested by Hodgson Table 4.

No differences between the two cultivars were observed during the wet season for any of the evaluated parameters. The eight accessions that were best in the combined analysis of all tested locations Valle et al.

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, Water balance was calculated Thornthwaite and Mather, using the average temperature and accumulated monthly rainfall Figure 2.

Stapf, Brachiaria decumbens Stapf, Brachiaria ruziziensis R. Discussion 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.

The Akaike information criterion was used to select the covariance matrix Wolfinger, The data were grouped according to the season of the year as follows: However, it was also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in the calculation of HA.

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. Crop Breeding and Applied Biotechnology 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.

Average daily gain ADG was analyzed using multivariate repeated measures analysis according to Littell et al. The steers were distributed according to weight so that the average weight in each paddock was the same. The samples were divided into two sub-samples.

Decreased bite depth is commonly associated with increased time per bite, decreased bite rate Palhano et al. Beachiaria this context, Valle et al.

The height at each point was considered to be the average canopy height surrounding the ruler. Three steers were placed in each paddock, in a total of 36 steers. Proceedings of the 19th International Grassland Congress.

These traits 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.

Grass and Forage Science However, differences between experimental years were observed for the remaining variables quantified Table 5. Stocking brahciaria and live weight gain per area ipata higher for the first year, lower for the second year, and intermediate for the third year.

Another factor that may be related to forage ingestion by animals and consequently to their performance is herbage allowance. Conclusions Brachiaria brizantha cv. Ingestive behaviour, herbage intake and grazing efficiency of beef cattle steers on Tanzania guinea grass subjected to rotational stocking managements.

The Journal of Agricultural Science The grazing method used was continuous stocking, with a brachkaria stocking rate.
