A community-based sheep breeding program has been implemented in the highlands of Ethiopia to improve the body weight of Menz sheep. It is important to evaluate the potential consequences of such a breeding strategy on herd dynamics. For this purpose, a dynamic, stochastic herd model was built. The model adopts a system dynamics methodology to study the effect of genetic improvement of body weight...
A bio-economic model was adapted to estimate economic values for important traits of two Ethiopian indigenous sheep breeds, the Menz and Horro breeds. To do so, a meat sheep herd for fattening lambs and rearing young replacement sheep was simulated. Traits included in the analysis were: daily gain (fattening trait), live weight of ewes, length of productive life, lambing interval, litter size, stillbirths...
