Linkages and Networking The executive committee of the Animal Production Society of Kenya, in response to an invitation by the Tanzanian Society of Animal Production, nominated Dr. Mwandotto to present a paper on "Smallholder Small Ruminant (Goat) Production" to the annual scientific meeting of the Tanzanian Society of Animal Production, 25-27 September 1990. Conditional on availability of SR-CRSP funds, the Breeding project is interested in extending the Haemonchus gene mapping work into other LDCs and with sheep.
