Pasture structure and production of supplemented cattle in deferred signalgrass pasture

Authors

Abstract

Abstract:
The effects of supplement doses (0, 1, 2 and 3 kg ha-1 day-1) and grazing periods (1, 28, 59, 89 and 103 days) on the B. decumbens cv. Basilisk structure and cattle production in deferred pastures were evaluated. The design was a randomised complete block design with two replications. The sward height and the total forage and stem masses decreased with grazing period. The crude protein (8.12%) and in vitro organic matter digestibility (52.74%) were not affected by grazing period. The fibre content in neutral and acid detergent increased linearly with the grazing period. The average daily gain of cattle ranged from 0.419 to 1.019 kg animal-1 day-1; the stocking rate ranged from 2.7 to 3.9 animal unit ha-1; and the average gain per area ranged from 2.7 to 7.9 kg ha-1 day-1, with the maximum values obtained with the highest dose of concentrate. Concentrate supplementation increases cattle production in deferred pastures. During the use of deferred pasture in winter there are decreases in the quantity and quality of forage, as well as limitations in its structure.
