Quantitative methods to determine factors affecting profits of lamb fattening enterprises
- Department of Livestock Economics, Faculty of Veterinary Sciences, Ankara University, Diskapi Ankara, Turkey
The purpose of this study was to demonstrate the use of profit function regression model as a possible practical decision support tool in the lamb meat production. It was found that all independents variables except ?Fattening Duration?, ?Capacity Use?, ?Total Other Expenditures? and ?Number of Lambs?, had strong statistical associations (P < 0.01) with the profit from per kg live-weight. Because marginal impact of each independent variable on the profit was the estimated co-efficient value, they could simply be used to evaluate ?what-if scenarios? and the risk of investment under changing circumstances in lamb meat production. It is, therefore, intended that lamb meat producers could use such modelling approach as a practical decision support tool.
