Asia is a region of dynamic economic changes, fuelled by rapid population growth, urbanization, increased incomes, demand-led processes and changing consumer preferences for foods of animal origin. The projected total meat and milk consumption levels for 2020 are far in excess of anticipated supp...


Devendra, C.[Animal production and rainfed agriculture in Asia: Potential opportunities for productivity enhancement]Animal production and rainfed agriculture in Asia: Potential opportunities for productivity enhancement

Rapid growth of the human and livestock populations in sub-Saharan Africa is creating unprecedented increases in food and feed demands. These population pressures on a fixed landbases are likely to promote severe competition for resources and drive agriculture progressively towards intensificatio...

Cattle rearing in humid West Africa was nearly impossible in the past owing to the prevalence of trypanosomiasis. However in recent times, with population pressure, jungle clearance, crop cultivation and tsetse control measures, the challenge has been reduced. Consequently there has been an influ...

In the process of developing an improved fallow system based on forage legumes, the potential interest of crop-livestock farmers in enhancing soil fertility restoration and dry-season feed supply was assessed during a socio-economic study on 11 farms of settled agro-pastoralists in the subhumid z...

A study was conducted in the humid-forest, forest-savanna, and Guinea savanna zones of West Africa from 1993 to 1999 to examine the effect of managing crop residues from cereal-legume cropping systems for mulch and fodder for sheeIncreasing the proportion of total crop residues produced from a un...

The moist savannah zone in sub-Saharan Africa is regarded as a high potential area for crop and livestock production. Currently, human labour is the principal source of power for crop production and the level of commercial energy use is very low. Agropastoralism and pastoralism are the principal ...

Integrated crop-animal systems are important in Asia. Both ruminants and non-ruminants are used in a variety of combinations with annual and perennial crops in Indonesia, the Philippines, Malaysia, China and Sri Lanka. These combined systems provide distinct economic benefits, and are more compat...

The potential of 3-year-old grazed pastures of Stylosanthes hamata, Chamaecrista rotundifolia and Centrosema pascuorum to contribute to subsequent maize production was investigated in subhumid Nigeria in 1993. All three legume pastures had the ability to give better maize grain yields than native...


Tarawali, Shirley A.Peters, Michael[The potential contribution of selected forage legume pastures to cereal production in crop-livestock farming systems]The potential contribution of selected forage legume pastures to cereal production in crop-livestock farming systems

The role of livestock in nitrogen cycling in mixed crop-livestock farming systems of sub-Saharan Africa was explored. Cattle were fed a range of diets to investigate the effects on partitioning of nitrogen between urine and faeces and on the chemical composition of the manures produced. The trade...

The integration of crop and animal production is well developed in the farming systems of Asia, particularly those in small-scale agriculture. There is marked complementarity in resource use in these systems, with inputs from one sector being supplied to others. Specific examples of the main crop...
