    A survey of abomasal parasites in cervids from Central Spain was conducted at 3 sites, Quintos de Mora (Toledo), Maluéñez de Arriba (Cáceres), and La Herguijuela (Cáceres). Commonly occurring helminths belonged to 3 polymorphic species of the Ostertagiinae: Spiculopteragia asymmetrica/S. quadrispiculata, Ostertagia leptospicularis/O. kolchida, and O. drozdzi/O. ryjikovi. Trichostrongylus axei was found in very few cases. Ostertagia drozdzi/O. ryjikovi and the minor male morphotype, S. quadrispiculata, are reported for the first time in red deer from Spain.

The book is divided in five sections. The first explores priority setting and research evaluation of commodity programmes. The second looks at institutional issues. The third explores issues related to commodity policies and food security.

    In order to identify options suitable for providing livestock feed in the wetter part of the moist savanna, the DM yield, botanical composition, crude protein, in sacco digestibility and neutral detergent fibre of combinations of 4 herbaceous legumes and 2 grasses were evaluated between June 1994 and December 1995 at Ibadan, south-western Nigeria. The legumes, Stylosanthes guianensis, Aeschynomene histrix, Centrosema pubescens and Chamaecrista rotundifolia, were each planted in combination with Brachiaria ruziziensis and Cynodon nlemfuensis.

    Agricultural growth will prove essential for improving the welfare of the vast majority of Africa’s poor. Roughly 80 percent of the continent’s poor live in rural areas, and even those who do not will depend heavily on increasing agricultural productivity to lift them out of poverty. Seventy percent of all Africans— and nearly 90 percent of the poor—work primarily in agriculture. As consumers, all of Africa’s poor—both urban and rural—count heavily on the efficiency of the continent’s farmers.

    The Systemwide Livestock Programme (SLP) of the Consultative Group on International Agricultural Research (CGIAR) works to alleviate poverty, protect natural resources and achieve food security in developing countries. The SLP has completed two transregional projects designed to identify the common factors that drive crop-livestock intensification and determine access to markets for smallholders. Working across three continents, the first project looked at farming systems operating at different levels of intensity.
