“…The CP is at the upper range. Herbage ME in oil palm plantations in West Malaysia is reported to be 7–10 MJ kg −1 DM (Dahlan et al, 1993; Lane & Mustapha, 1983) and CP is reported to be 11%–16%, but sometimes the ME can be as low as 4.6 MJ kg −1 DM and the CP as low as 8% (Dahlan et al, 1993; Wattanachant et al, 1997).…”

“…The energy production of herbage available for grazing was reported by Dahlan et al (1993) to decrease from 34 MJ ME ha −1 day −1 in a 3 year old oil palm plantation to 10 MJ ME ha −1 day −1 in a 15 year old oil palm plantation. There was a corresponding decrease in CP from 12.7% to 9.2% of the understorey plant DM in 9–16 year old plantations when grasses replaced the broad leaf plants in older plantations (Wattanachant et al, 1997).…”

Background: Oil palm is a tropical crop with worldwide plantings approaching 20 million ha and large areas in Indonesia, Malaysia and Thailand. The plantations are readily managed as silvopastoral systems incorporating cattle grazing (Oil Palm Silvopastoral System for Cattle, OPSC) but there is a need for analytical tools and data to understand system herbage supply and feed conversion efficiency (FCE). Methods: Metabolic energy budgeting was used to estimate herbage harvested by cattle in three OPSC subsystems, 9 and 12 years after oil palm establishment, and FCE of the subsystems was determined. Understorey herbage was also analysed for nutritive value, botanical composition and herbage accumulation within one grazing-regrowth cycle. Results: The herbage-harvested estimate was 2.0−2.4 t dry matter (DM) ha −1 year −1 for 9 year old subsystems and 1.4−1.7 t DM ha −1 year −1 for a 12 year old subsystem. Herbage metabolisable energy (ME) was 8.3−8.5 MJ kg −1 DM and crude protein (CP) was 15%−16% DM. FCE values for subsystems ranged from 32 to 94 kg DM kg −1 liveweight-gain. Conclusions: Herbage DM yield is declining, while herbage ME is marginal but CP is adequate. FCE is suboptimal but can be optimised by defining the trajectory of declining herbage production with canopy closure as plantations age and matching stocking rate to herbage supply using a comparativestocking-rate-type statistic.
