Increased production and utilization of pasture and forage
This paper summarises the main lines of research and development of recent years having special reference to underdeveloped countries. In the long-term the greatest advances have been made in fundamental knowledge, such as - the basic physiology and biochemistry of plant growth, the significance of the C4 pathway in tropical plants, genetic engineering, embryo transfer in animals, remote sensing photography and the ecology of the world's grasslands. The pressing problems of rangeland degeneration, and social and economic change in human societies, are also better understood. The immediate problem and the task of this paper is to descend to a lower practical level of what has been learned about the possibilities of increasing pasture and forage production, and of utilising feed grown in the most efficient manner. The recent pasture utilisation studies with sheep in the temperate zone and the arid and semi-arid pastoral zones are discussed, followed by the cropping/livestock situation in the semi-arid and subhumid zones and finally to the subhumid and humid zones
