Sarawak, which is free from the incidence of foot and mouth diseases, is embarking in livestock-oil palm integration as a strategy to increase local livestock production. The abundance of undergrowth in oil palm plantation offers a free source of forage for livestock integration. It has been reported that the nutritive value of these forages is comparable to some improved pasture grasses.
However, the compositions of the undergrowth in oil palm plantation is dependant on various interacting environmental factors, especially the limits on light penetrating the ground as oil palm matures due to the canopy closure. There is little information on the quantity of vegetations and composition of undergrowth species in Sarawak oil palm plantation. Hence, a study was conducted by researchers from the Faculty of Resource Science and Technology, University Malaysia Sarawak at a mature oil palm plantation (13 years old oil palm trees) in Sarawak to identify the major undergrowth species and determined the quantity of vegetations at different intervals after the grazing activities.
Random sampling was conducted in selected blocks and the selection of blocks was based on post-grazing intervals (current, 1 month, 3 month and 5 month post-grazing interval). Six botanical groups were found in the oil palm plantation, namely grasses, broadleaved plants, legumes, sedges, ferns and palms. Grasses had the largest population in the oil palm plantation ecosystem. The observation of undergrowth in oil palm plantation indicates that most of the species are suitable for livestock production though selective weeding may be necessary for non-edible ones.
The finding of the study showed that shade tolerant plant species tend to dominate the ecosystem in mature oil palm plantation as the canopy close. The emergence of these shade tolerant species in mature oil palm plantation is important as they ensure continuous supply of forages for livestock production.
The Sarawak oil palm industry will continue to expand and livestock-oil palm integration system is emphasised in the 3rd National Agriculture Policy (NAP3, 1998-2010) as a holistic approach to maximise land use and increase farm income. But there are concerns regarding to the effects of soil compaction due to animal trampling and of increase complexity in management practices. The problem here is that there is not much research conducted in Sarawak to demonstrate the benefits of livestock integration on the soil, crop and livestock productivity. Thus, there are urgent needs to continue to explore the potential of this system in the areas where livestock integration has started.
ABOUT UNIVERSITI MALAYSIA SARAWAK (UNIMAS)
UNIMAS was established in 1992. The University's mission is to generate, disseminate and apply knowledge strategically and innovatively to enhance the quality of the nation’s culture and prosperity of its people. The knowledge creation initiatives at UNIMAS are premised partly upon the wealth of natural resources and diverse socio-cultural make up of the State of Sarawak. UNIMAS commitment to research has already been recognized by the stakeholders and partners in industry through provision of endowments for the establishment of eight research chairs; these include the Tun Zaidi Chair for Medicinal Chemistry, the Tun Openg Chair for Sago Technology, the Shell Chair for Environmental Studies, and the Sapura Chair for ICT.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
