Presents a theoritical outline of the techniques in the use of tritiated water (HTO) which can be used to estimate total body water, body composition, water turnover, milk intake and feed intake. Highlights its potential errors and gives a comprehensive methodology for the use of tritiated water under field conditions.

Presents results of studies on the utilization of agricultural by-products as livestock feeds in Africa. Discusses methods of estimating the nutritive value of fibre residues and feed legumes, feed intake and digestibility, prospects of utilizing urea-treated maize stover, agroindustrial by-products and the chemical analysis of feeds.

This article discusses the zoning of 'Communual Areas' on tribal grazing land in Botswana, in which communities retain collective land rights.From the experience gained during six years of attempting to establish and operate communal grazing cells a number of conclusions can be drawn in relation to co-operative action and development project approaches and in the communal areas of Botswanahe communal grazing cell scheme was badly designed.

Examines the consequences for cattle husbandry of livestock-crop integration as practiced in an agropastoral production system in the sub-humid zone of Nigeria - based on a study of herding practices and cattle grazing behaviour.

Presents results of a study of grazing behaviour and forage resources utilisation by herded cattle belonging to agropastoralists at Abet & Kurmin Biri in the subhumid zone of Nigeria as well time spent on walking, resting & watering. Subdivides grazing activities into natural range grazing, browsing, grazing of crop residues and of burnt areas.

Summarises the work that ILCA is doing to assemble what information is available on livestock breeds and breeding in sub-Saharan Africa.

Describes interactions between cropping & livestock husbandry in an area of Fulani settlement arid farming groups at Abet and in a Fulani agropastoral system at Kurmin Biri, both in subhumid Nigeria, identifying the linkages as being feed from fallow land crop residues (CR) grazing and use of cattle manure in cropping w.

Reports findings of baseline studies as size of cultivated area, cropping patterns, management in relation to fallowing and labour & other inputs, yields and constraints to increasing grain & forage production among traditional crop farmers and Fulani agropastoralists at Abet & Kurmin Biri, both in subhumid Nigeria.

Reports findings from a study of spheres of influence of men & women, esp. as they affect the dairy subsector, in Fulani agropastoral households in Nigeria; with particular reference to decision making & control over herd management; milking; allocation & utilisation of milk; milk processing & marketing; household income from milk sale; womens' household expenditure and investment in agropastoral production. Analyses implications of these for development of dairy production.

Outlines some of the work being done by ILCA in the field of agroecological zonation and the use of models to predict the effect of environment on pastoral and agricultural systems. Includes plans for future developments and the potential benefits of the work.
