| Abstract | ||
| rovinceMinimizing of meat production costs is one of the most important goals of sheep feedlot farms and failure in this area leads to bankruptcy of these farms. In order to investigate the management status of feedlot sheep farm in Lorestan province and estimation of live weight production function, the technical efficiency of thesefarms, data from 80 active sheep feedlot farms were collected in Lorestan province, using a questionnaire and in-person interview. The data related to the production functions were analyzed by Cobb-Douglas functions, technical efficiency of the farm, and correlation of some of the traits were determined using SAS9.1, SPSS16 and Eviews7 software. The results showed that average daily gain (ADG), feed intake and feed conversation ratio were 0.192 kg, 1.43 kg and 7.45 ± 2.05 respectively. The average of technical efficiency for industrial fattening was 53%, which indicates the significant potential of fattening farm in increasing their yield. Based on the results, the correlation coefficient between technical efficiency and first body weight, final body weight, daily gain and total weight gain in each period was positive and significant. In general, factors such as educational level, extension training, nutritional status, use of balanced diet and the health status of farms had significant effect on the technical efficiency of the studied farms. Therefore, the implementation of proper management methods can improve the performance of the feedlot farms of sheep in Lorestan province. | ||
