Quantifies some of the benefits to range resource use and human food supply from multiple species stocking in African livestock systems. Gives examples of the use of range resources by camels, cattle, goats and sheep in terms of the percentages of total time spent on feeding. Presents productivit...

Presents the objective of the programme, viz., to implement currently available options for nematode control including rotational grazing systems and identification of effective dewormers. Preliminary results on these are presented here. Research on the identification of resistants genotypes is i...

A selection programme (PNSO) was set up in 1983 in Cote d'Ivoire to increase growth and liveweight of the indigenous Djallonke sheep, using open nucleus breeding system. Selection was based on male individual weight at 80, 180 and 365 days of age. This paper Reports results of analyses of 10,417 ...

This Report compares the efficacies of three anthelmintics, each belonging to one of the broad spectrum groups. It also identifies the genera of resistant worms through larval culture. The study was conducted on a commercial farm where anthelmintics had been used intensively. The results show cle...
