Covariance structure selection in general mixed models.

A third ecotype, registered as cv. 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. 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 use of improved forage plants may help mitigate this problem. The percentages of each component were used to estimate the leaf: The experimental area was 8.

The experiment was conducted between June and May 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.

Three tester steers were used per paddock. Decreased bite depth is commonly associated with increased time per bite, decreased bite rate Palhano et al. The data were grouped according to the season of the year as follows: For the stratified herbage samples, the same model was applied, but the effect of the strata was added and considered fixed.


However, in the study conducted by Euclides et al. 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 herbage allowance Allen et al. In this context, Valle et al.

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. 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 data indicate that herbage allowance did not limit forage ingestion and consequently live weight gain, during the dry season Table 4.

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. Rainfall, average relative air humidity, and minimum, average, and maximum temperatures Figure 1 were collected from a meteorological station close to the experimental site. Revista Brasileira de Zootecnia Based on previous analyses, the highest-order polynomial was selected.

Grazing behaviour, herbage intake and animal performance of beef cattle heifers on marandu palisade grass subjected to intensities of continuous stocking management. This finding is of great importance because the seasonality of forage production is brizangha of the bottlenecks for pasture-raised cattle production. 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.

Crop Breeding and Applied Biotechnology This finding is in accordance with those described by Carvalho et al. Pasture samples were collected once a month, and herbage accumulation rate HARpercentage of leaves PLleaf: Three steers were placed rbizantha each paddock, in a total of 36 steers.

Herbage inside and outside of the cages was harvested at the ground level and sampled as described above; then, herbage mass was determined. O melhoramento de forrageiras tropicais no Brasil. 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.
