Evaluation of technical efficiency and model of calve fattening in Guilan province

In order to study of calve fattening status,determination and improvement of their Technical efficiency(TE) and Offering of proper model for calve fattening farms of Guilan province this research were done. In phase 1, questionnaires were compeleted in 70 farms that were selected by randomized sampling method classified with proportionate appointment and having equal or more than 20 calve, and information were acquired. By using Statistical Production Frontier method, TE were estimated and effects of different factors on mean of TE through one-way analysis of variance and Duncan test were evaluated. Linear and Transcendental production functions were estimated through Ordinary least square(OLS) method, and using of SPSS 12.0 for Windows software.After determination of TE in 70 farms, in second phase,farms were ranked and first 20 farms with high TE Randomizely divided in two standard and experimental groups.In experimental group scientific method of fattening were used, and in standard group fattening were done by current method.Finally, Average of TE in two groups were compared with each other by using of t test. In phase one, Average TE were 47.02%. Average daily gain were 701 grams.Average fattening length were 144.5 days.Average daily crude protein intake were 940 grams.Average daily metabolizable energy intake were 17.36 Mcal. Average active number of calf in farms were 27 calve. The most Coefficient of correlation was between TE and total calf gain in fattening period(0.843).TE and daily gain were not significantly affected by zone(p>0.05). In second phase, average TE in experimental group(0.60) were more than standard group(0.33) and significantly different with each other(p<0.025).On the basis of results of this research, we can improved TE by Correct education of farmer and better management in calve fattening farms of Guilan province.
