This research was conducted at the livestock Farm Mururé, which is located in Third Section, Canton "La Enconada" Township festering Cotoca. The objective was to evaluate two formulations of food in a confined system in the phase of fattening cattle breed Nelore to determine and quantify the variables of consumption, body weight gain and feed conversion among different treatments the effect of the two food types and compare differences in feed costs by the use of concentrated feeding, above the basis of conventional food, used in the experiment. 45 young bulls Nelore of 3years old were used, divided into three groups of 15 each. The same ones were evaluated in the final stage of fattening (90 days), with three different types of food in a confined system. The experimental design was completely randomized with three treatments and 15 repetitions. Each repetition was an animal. The treatments consisted of diets: conventional diet in the form of flour without pre vitamin mixture (control); conventional diet plus core of Nutripec and conventional diet plus Vet-chemistry core. The results reported an increaseof 1,417 kg / day in animals supplemented with inputs Nutripec and 1.326 kg/day with inputfrom Vet-chemistry compared with control animals whose weight gain was 0.790 kg / day. Economically the most profitable level treatment was the one supplemented with Nutripec, offering better benefits than the control group.
