A simulation study was conducted to optimize a cooperative village-based
sheep breeding scheme for Menz sheep of Ethiopia. Genetic gains and
profits were estimated under nine levels of farmers’ participation and
three ...
Breeding programs for smallholder sheep farming systems: I. Evaluation of alternative designs of breeding schemes
Village- and central nucleus-based schemes were simulated and evaluated
for their relative bio-economic efficiencies, using Ethiopia’s Menz sheep as
example. The schemes were: village-based 2-tier (Scheme-1) and 1-tier
(Scheme-2) ...
