Cím:Factors influencing the gross value added in the sheep production chain / B. Cehla, S. Kovács, M. Wolfová, I. Komlósi & A. Nábrádi
Megjegyzések:The competitiveness of the sheep sector in East Europe has been decreasing from year to year. The value added in the sector is notgenerated in the countries as a high proportion of the lambs are exported. For example, in Hungary, 95% of the lambs, unnecessary forreplacement, are sold at an average weight of 21 kg and are slaughtered abroad. A stochastic model was constructed to investigate theconnections between the cycle phases of the mutton production. Three modules were distinguished, the lamb production, fattening andslaughtering-processing sub-modules. The aim of our study was to identify the gross value added generated in the three sub-modules and toanalyse the main factors influencing its volume using the conditions in Hungary as an example. The major hypothesis of our research wasthat the profitability of the production chain is mainly determined by the breed. The results showed that, considering market prices, the grossvalue added in the processing module was mostly influenced by the number of lambs sold per ewe per year at the bottom level of the muttonproduct chain. The next most important factors were the weight gain in the lamb producing and fattening sub-modules and dressingpercentage in slaughtering-processing sub-module. Contour plots were constructed which help to describe the relationship among analyzedfactors. Using the contour plots, the gross value added for different combinations of these factors might be forecast.
