“…It is also noteworthy that forage availability decreases and the canopy structure becomes limited during the grazing period, due to the phenological alteration of the plants and the effect of grazing itself (5) . These changes in deferred pasture structure in the grazing period affect ingestive behaviour and consequently, animal performance.…”

Pasture structure and production of supplemented cattle in deferred signalgrass pasture

et al. 2020

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.

“…However, when the pasture is used as the main food source, it has little growth opportunity and may not meet the demand of the herd during the winter of the Southeast and Midwest of Brazil. In this context, deferment of pasture, which consists in removing animals from pasture at the end of the growing season in order to accumulate fodder for use in the off season, can be a viable, easy and relatively low cost alternative to ensure pasture supply in the winter (Euclides, Flores, Medeiros, & Oliveira, 2007;Silva, Montagner, Euclides, Queiroz, & Andrade, 2016).…”

The deferred pasture structure determines the consumption and performance of grazing animals and, in addition, can be influenced by the duration of the deferment period and nitrogen (N) fertilisation. The objective of this work was to evaluate the structural characteristics of Brachiaria brizantha syn. Urochloa brizantha cv. Piatã (piatã palisadegrass) deferred for two periods (79 and 127 days) and with four N doses (0, 40, 80 and 120 kg ha-1) in the Zona da Mata of Minas Gerais, Brazil. The experimental design involved complete randomised blocks and a subdivided plot scheme, with three replications. The 127-day period of deferment resulted in a higher forage mass, falling index, stem percentage and density, but a lower number of tillers, percentage and volumetric density of live leaf blade. The N dose increment, in general, worsened the structural characteristics of the piatã palisadegrass deferred for 127 days. However, with the 79-day period, the N fertilisation increased the volumetric density of live leaf blades and reduced the stem percentage in the forage mass. As a preliminary recommendation, piatã palisadegrass can be deferred for 79 days and fertilised with up to 90 kg ha-1 of N in the region of Zona da Mata de Minas Gerais, Brazil.

“…To circumvent or minimize the problems resulting from low forage production throughout the dry season, stockpiling pasture is an appropriate management strategy (Santos et al, 2009a;Silva et al, 2016). It consists of excluding a pasture area from grazing in late summer or early autumn.…”

This study aims to evaluate the effects of height (15 and 30 cm)and nitrogen dose (N, 40, 80, and 120 kg ha-1) at the beginning of thestockpiling period on the structural characteristics of the Urochloabrizantha cv. Marandu (Marandu palisade grass) during winter. Thefalling index of the plant did not vary with the factors under scrutiny(P>0,10). The number of basal tillers was higher (P<0,10) in the 15-cmdeferred canopy than in the 30-cm canopy only when the highest N dosewas used. Under conditions of application of 0 or 80 kg ha-1 of N, the 30-cmstockpiled canopies showed a higher (P<0,10) forage mass than the 15-cmones. Associated with reduced canopy height at the beginning ofstockpiling period, nitrogen fertilization improves the morphologicalcomposition of Marandu palisade grass. To maximize the forage mass inthe dry season, the canopies of Marandu palisade grass can be deferredeither at 15 cm (fertilized with about 100 kg ha-1 of N) or at 30 cm (with nonitrogen fertilization) at the beginning of the stockpiling period.
