Abstract :
The aim of this study was to evaluate and measure the energy in broiler farms in Qazvin and determine how well the units were in Qazvin province. For this study, a questionnaire was drawn up and Farmers were interviewed in person. A total of 20 units were vector data.In order to determine how well the meat cattle Qazvin Province of DEA (DEA) was used. Calf fattening period in Qazvin province , usually between 10 to 12 months. Weight between 140 to 180 kg fattening and slaughter weight is between 450 and 500 kg. Units of study include the 1019 calves. Calculations for a period of one year fattening is done in 94-1393.The results showed that the highest share of energy consumption in the cattle studied were related to animal feed ٢٢۴۶٨١۴٩/٠٧ MJ energy in a way that was. After energy use in cattle feed of meat most of the fuel was ۵١۴٩۶٧۵/٢٢ MJ energy that was. Energy ratio for cattle studied ٠/١۵٢ , Energy efficiency ٠/٠١٢ MJ kg and Pure Energy added -٢٧۴٠۵۵٣٢/٢ MJ was. From 20 cases in the province , effective 4 units and 16 units were inefficient. In this study, an average inefficiency inefficient units was ٨٢/۶٩
