Sward structure and herbage yield of rotationally stocked pastures of 'Marandu' palisadegrass [Brachiaria brizantha (A.Rich.) Stapf] as affected by herbage allowance

Abstract: In ruminant-forage systems herbage allowance (HAL) has a major impact on grazing intensity and sward structure, affecting animals, plants, and ultimately, pasture yield. Data on HAL responses of tropical cultivated pastures are scarce and this information may be useful in optimizing pasture utilization. The objective of this study was to describe and contrast sward structure and herbage accumulation responses of 'Marandu' palisadegrass [Brachiaria brizantha (A.Rich.)

“…This was particularly the case on the 100% LI treatments, the consequence of more intense flowering. Similar results were reported by Santos et al (1999); Santos et al (2004); Barbosa (2004); Cândido et al (2005) and Lopes (2006) for rotationally stocked mombaça and tanzânia guineagrass and by Braga et al (2006) for marandu palisadegrass (Brachiaria brizantha (A.

“…(Cauduro et al, 2006), even with r 2 lower than 0.70 due to excessive amounts of dead plant material at the base of the sward. Overall, research suggests that for temperate grasses both SSH and RP readings have good applicability giving both good herbage mass estimates, as r 2 often exceeds 0.90 and the CV are seldom above 10% (Bransby et al, 1977;Santillan et al, 1979;Griggs & Stringer, 1988).…”

“…Indirect methods reduce sampling time and costs and increase precision (Bransby et al, 1977). Among the many options sward surface height (SSH) and rising plate meter (RP) readings (Gonzalez et al, 1990;Da Silva & Cunha, 2003) have been most frequently used as indirect methods of herbage mass estimation.…”

“…Em razão da elevada produção de forragem e do hábito de crescimento cespitoso, o manejo do capimtanzânia exige cuidados, especialmente no que diz respeito ao excessivo crescimento dos colmos (Santos et al, 2003b), que pode infl uenciar negativamente no crescimento posterior das plantas (Braga et al, 2006) e reduzir o acúmulo de forragem. Ao mesmo tempo pode modifi car a estrutura do dossel, de modo a prejudicar o consumo de forragem e o desempenho animal (Alexandrino et al, 2005).…”
