Brachiaria Brizantha cv BRS Piatã
A completely randomized blocks experimental design was used, with two treatments and six replicates. Modelling covariance structure in the analysis of repeated measures data. Ingestive behaviour, herbage intake and grazing efficiency of beef cattle steers on Tanzania guinea grass subjected to rotational stocking managements. John Wiley, New York.
The herbage allowance Allen et al. The soil was corrected with application of 2. This finding is in accordance with those described by Carvalho et al. However, it was also believed to not limit herbage ingestion by animals because herbage accumulation was not considered in the birzantha of HA.

Herbage inside and outside of the cages was harvested at the ground level and sampled as described above; then, herbage mass was determined. 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 brachairia to biotic and abiotic factors Valle et al. The grazing method used was continuous stocking, with a variable stocking rate.
Standard errors of the mean are indicated between parentheses. Average daily gain ADG was analyzed using multivariate repeated measures analysis according to Littell et al.
Based on previous analyses, the highest-order polynomial was selected. Stapf, Brachiaria decumbens Stapf, Brachiaria ruziziensis Brschiaria. Revista Brasileira de Zootecnia The remaining animals were kept at a reserve pasture 7. 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.
Conclusions Brachiaria brizantha cv. However, in the study conducted by Euclides et al. How to cite this article. This finding is of great brachiaaria because the seasonality of forage production is one of the bottlenecks for pasture-raised cattle production.
The Akaike information criterion was used to select the covariance matrix Wolfinger, Statistics in Medicine The samples were divided into two sub-samples.
The pronouncedly lower HAR for the dry season, regardless of the grass cultivar Table 2resulted mostly from the water stress observed during the dry season Figures 1 and brixantha.

Communications in Statistics – Simulation and Computation Water balance was calculated Thornthwaite and Mather, using the average temperature and accumulated monthly rainfall Figure 2. Therefore, it was decided to reduce the stocking rate per paddock during the second and third dry seasons Table 2. Live weight gain per area was calculated as the product of the brkzantha daily live weight gain of tester animals and the total number of animals tester and grazer per paddock and grazing cycle.
Three tester steers were used per paddock.

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.
In this context, Valle et al.
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.
Another factor that may be related to forage ingestion by animals and consequently to their performance is herbage allowance.

Thus, Brachiaria brizantha cv. Discussion The observed herbage accumulation rate variation Figures 3 A and 3B was btizantha for the tropical regions, resulting from the rainfall seasonality Figures 1 and 2 and temperature and photoperiod variations Figure 1. The Journal of Agricultural Science Therefore, the canopy structure observed in the present study likely led to decreased animal nutrient intake, resulting in a lower ADG.
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.
For the stratified herbage samples, the same model was applied, but the effect of the strata was added and considered fixed.
Three steers were placed in each paddock, in a total of 36 steers.
