Production costs are very meaningful about business quality and it is a decision-making condition for every producer; lowest cost level is the standard in choosing the right option. These researches were intended to give an overview about these problems. Objectives were first to find unit costs for feeds and kg live weight to broilers type Certificate and second to reduce unit costs by changing energy and protein content of feeds for these broilers. Experiment was performed with Ross 308 chickens, raised according to the technology to produce ecological poultry meat type Certificate. Three experimental variants were used; respectively three treatments/each variant and experiment design was in pens. Experimental period was of 56 days of age; feeding technology used was bi-phase, as following: group CM, with constant energy and protein level, group C1, with constant energy and variable protein level and group C2, with variable energy and constant protein level. Major production performances were checked and slaughtering was followed by cutting and finally all data were processed and read statistically. Finally unit costs per kg processed feed (1,308 – 1,362 lei) and per kg live weight (5,532 – 5,667 lei) were analyzed. Key words: certificate, cost per live weight, unit cost, weekly average gain INTRODUCTION Cost is an extremely useful economical tool for decision making about resource usage, production amount and structure, increasing or decreasing product range, technological innovation, etc., in market oriented economies. Input consume for making such goods and services is found in their prices. Production cost in included in price and it must be calculated because: resources are limited; a smaller production cost makes a higher income possible; a smaller production cost keeps your clients and satisfies your share partners, administration board and employees 1 . A production cost means all costs for inputs consumption performed by the enterprise for goods and services produced and offered. Production costs are very meaningful about business quality and it is a decision-making condition for every producer; lowest cost level is the standard in choosing the right option 5 . These researches were intended to give an overview about these problems. Objectives were first to find unit costs for feeds and kg live weight to broilers type Certificate and second to reduce unit costs by changing energy and protein content of feeds for these broilers. MATERIAL AND METHOD Experiment was performed in S.D.E. Avicola Moara Domneasc , experimental station of the University of Agriculture and Veterinary Science Bucharest, for Certificate type broilers, on three pen trials with even body weight and proportion of sexes in block trials. Chickens were Ross 308 and they were raised according to standard technology for this breed and in the same conditions of management, feeding and watering 3 . There were performed three treatments for every experimental flock to find bird’s qualitative and quantitative performances and experiments were performed in the same time and with the same biological material and in the same unit. Trial schedule was designed for Certificate chickens and it was as follows: treatment I (M): even energy and protein level; treatment II (E 1 ): variable protein level and even energy level; 250 Scientific Papers, Animal Science, Series D, vol.
