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

Following each harvest, the cages were placed at other points within the paddock according to the same method. A completely randomized blocks experimental design was used, with two treatments and six replicates. The samples were divided into two sub-samples.

Revista Brasileira de Zootecnia Herbage accumulation rate was higher for the third than for the second experimental year, and HM was lower for the second than for the braciaria experimental years. The experimental area was 8. 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 height at each point was considered to be the average canopy height surrounding the ruler. In this context, Valle et al. The sward height was measured twice a week at 60 random points per experimental unit, using a ruler graduated in centimeters.

In addition, btizantha uncertainties regarding climate changes lead to different predictive strategies for breeding programs. Grazing behaviour, herbage intake and animal performance of beef cattle heifers on marandu palisade grass subjected to intensities of continuous stocking management.


John Wiley, Brizanthha York. July 30, ; Accepted: The Journal of Agricultural Science Evaluation of Brachiaria brizantha ecotypes under grazing in small plots. However, it was also believed to not limit herbage ingestion piaa animals because herbage accumulation was not considered in the calculation of HA.

The soil at the experimental area is a Dystrophic Red Latosol Embrapa, Laboratory of Climatology, New Jersey. Of these accessions, two were selected and tested for animal production: Because of a delay in the building brrachiaria the exclusion cages, herbage accumulation was not estimated for the first experimental year.

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. 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.

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

Animals were weighed every 28 days. Tester and “grazer” animals were weighed monthly following a h fast. For the stratified piatq samples, the same model was applied, but the effect of the strata was added and considered fixed. However, differences between experimental years were observed for the remaining variables quantified Table 5.

An international terminology for grazing lands and grazing animals.

In May, fences were built, and drinking troughs were installed. Three tester steers were used per paddock. Services on Demand Journal. 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. Statistics in Medicine
