Pigs can play an important role in risk diversification and livelihood security of many smallholder and poor households in Uganda. Women and youth/children provide most of the pig-production labour, especially for forage collection, feeding and watering; and they are responsible for about 90% of pigs produced in Uganda. In the smallholder productio...

The dairy sub-sector in the semi-arid zones of Kenya is constrained by inadequate feeds, inappropriate breeds, inaccessibility and high cost of artificial insemination (AI) services, high incidence of animal diseases and inaccessible credit services. A study with the objective of identifying important reproductive and animal health challenges in sm...
Book
Multi-nutrient mineral blocks are lick blocks containing energy, protein, vitamins, minerals and other nutrients. The feeding of the blocks is a convenient and inexpensive method of providing a range of nutrients required by both the rumen microbes and the animal, which may be deficient in the diet. Strategic ruminant supplementation is one of the...

The productivity of smallholder crop-livestock production systems in Eastern and Central Africa is threatened by adverse effects of climate change; with severe consequences on livestock feeds, water and household livelihoods. A project was implemented in Uganda, Kenya, Tanzania and Burundi during 2009-2011, to promote utilisation of drought toleran...
Article
Full-text available
Economically feasible strategies for year-round feed supply to dairy cattle are needed to improve feed resource availability, milk yield and household income for the smallholder dairy farming systems that predominate in the rural Eastern and Central African region. Currently, Napier grass (Pennisetum purpureum) is the major forage in zero-grazing p...

Livestock production is an important component of smallholder farming systems in Uganda. One main constraint to especially dairy production is the lack of sufficient quantity and quality feed on a consistent basis. Therefore, this study aimed to evaluate and identify forage legumes that are adapted to drought. An on-station experiment was establish...
Chapter
This book addresses issues related to intensification of banana-based cropping systems in the (sub)humid highland areas of Africa. The information that is presented in the 28 chapters of the book is based on research carried out in the Great Lakes Region by CIALCA (Consortium for Improving Agriculture-based Livelihoods in Central Africa) and partne...
