2009

The present study aims to deeply analyse the economic performance and the cost structure of Assaf and Awassi dairy sheep farms in the Autonomous Community of Castilla-Leon and to calculate their relative technical efficiency using the Data Envelopment Analysis (DEA). The information was obtained from 20 surveys addressed to farmers. Data refer to year 2008. The inputs included were: number of ewes, labour costs, other fixed costs and feed cost. The two outputs used were: milk sales, and other incomes excluding subsidies. Variables were expressed in euros per ewe and year. This analysis was based on models with variable returns to scale (VRS) under an input-oriented approach. Results show that structure was: family farms, average herd size of 598 sheep, average productivity per ewe and year: 310.6 litters and 1.09 lambs. Average ratio ewes per AWU: 238. Most farms (60 per cent) accumulated losses. The average total incomes are 317.4 euros/ewe/year. Feeding is the most important factor, followed by the cost of labour (familiar and hired). Depreciation and maintenance of equipment represents 25.98 euros/ewe/year. Unitary production cost of milk is 0.85 euros per litre. The breakeven point or minimum productivity to cover all production costs is 365.5 litters/ewe/year. The minimum flock size to cover all production costs is 737 ewes. The average level of global technical efficiency is 94.6 per cent, 98.3 per cent for pure technical efficiency and 96.3 per cent, for the scale one. It was found that 17 farms are technically efficient and 7 farms with scale inefficiency. The main inefficiency is found in feed and labour costs.
