The paper discusses the economics of substituting some ranging sheep with cashmere goats, employing a Linear Programming model. Studies of grazing pattern reveal that threes and bushes constitute about 50 percent of feed intake of browsing goats, compared to 10 percent for sheep. Goats are thus more efficient than sheep in reducing pasture encroachment. Under Norwegian climatic conditions encroachment of bushes and trees will not affect the probability of wild fires, however, maintaining open landscapes is considered an important goal for the development of the rural countryside. Comprehensive alteration from sheep to cashmere goats with eight months old kids averaging 11 kg slaughter weight, is unprofitable, assuming equal labour input of goats and sheep. However, goats are smaller and require less feed, thus the labour input of goats may be lower. Due to the low fibre yield cashmere goats are not as profitable as sheep, even excluding subsidies for wool. The fibre yield could be improved by breeding or by feeding the kids until 20 months (19 kg), making goats as profitable as sheep. The current agricultural support system treats sheep and goats equal. However, if Norway’s position in the ongoing WTO-negotiations to allow for extra payment forpreserving the cultural landscape (multifunctional agriculture) gains sufficient support, extra compensation for browsers should become interesting to the government in implementing the policy.
