This work was carried out to evaluate the effect of supplements based on non-protein nitrogen (NPN) as: urea, amirea and multinutritional block, on live weight gain and cost analysis for cattle kept in pastures. During a period of 104 days(April to July 2004), 40 crossbreed bulls, uncastrated and initial average weight of 379kg, were allocated into 4 paddocks with Brachiaria brizantha cv. Marandu, in continuous pasture system receiving, in troughs, the following treatments: mineral salt (control), protein supplement containing amirea, protein supplement containing urea and multinutritional block. The experimental design used was randomized blocks with repetition within the block. Results of availability bromatological composition of pasture, supplement consumption and daily weight gain of animals were evaluated in two experimental sub-periods: 0 to 45 and 45 to 90 days. In the first sub-period, there was no effect of treatments (P>0.05) on daily weight gain but in the second sub-period, the multinutritional block showed smaller (P0,05) no ganho de peso diário, mas no segundo subperíodo, o bloco multinutricional apresentou menor ganho de peso (P

O confinamento teve duração de 80 dias. As rações foram compostas mantendo a proporção volumoso:concentrado no nível de 63:37, com aproximadamente 13% PB. Não se constataram diferenças quanto ao ganho de peso diário (GDP) durante o período experimental total entre os tratamentos AL, UR ou AM (1,14; 1,17; e 1,23 kg/anim. dia), ou na ingestão de MS em % PV (2,63; 2,60; e 2,60% PV), em g/kg0,75 dia (136,19; 134,74; e 134,81) ou kg/anim. dia (9,42; 9,35; e 9,40), respectivamente. Os valores de ingestão de PB foram de 1,28; 1,24; e 1,34 kg de PB/anim. dia e de 18,54; 17,86; e 19,24 g/kg0,75 dia para os tratamentos AL, UR ou AM, não diferindo entre si. Valores obtidos para conversão alimentar da matéria seca foram de 8,41; 8,01; e 7,67 kg MSI/kg GPD e para conversão protéica, 1,15; 1,06; e 1,09 kg PBI/kg GPD, respectivamente, para os tratamentos AL, UR e AM, que foram semelhantes. The objective of this experiment was to evaluate the performance of feedlot beef cattle fed diets supplemented with protein concentrate based on cottonseed meal (CSM) urea (UR) or starea (ST), using corn silage as forage. The feedlot period was 80 days. The diets were constituted maintaining the forage:concentrate proportion in the 63:37 level, with nearly 13% CP. No difference was observed in daily weight gain during the experimental period among the CSM, UR or ST treatments (1.14, 1.17, and 1.23 Kg/anim day) or in the dry matter intakes in % LW (2.63, 2.60, and 2.60), g/kg0.75 day (136.19, 134.74, and 134.81) or kg/anim. day (9.42, 9.35, and 9.40), respectively. The CP intakes values were 1.28, 1.24, and 1.34 kg of CP/anim. day and 18.54, 17.86, and 19.24 g/kg.75 day for the CMS, UR or ST treatments and they did not differ among each other. Values of feed:gain ratios obtained for dry matter were 8.41, 8.01, and 7.67 kg DMI/kg DWG and for the protein:gain ratios, 1.15, 1.06, and 1.09 kg CPI / Kg DWG, respectively, for the CPM, UR and ST treatments, that were similar.

Foram utilizados 120 novilhos com 19 meses de idade e 358kg, sendo 60 Nelore e 60 F1 Brangus x Nelore, divididos em três tratamentos com 20 animais, alojados em piquetes de Brachiaria brizantha cv. Marandu de 10 hectares cada, totalizando 120 hectares, sendo dois piquetes por grupo genético e tratamento, pastejados alternadamente a cada pesagem (42 dias). Os tratamentos consistiram em mistura mineral com amiréia-150S (AM), mistura mineral com uréia+milho+enxofre (UR) e mistura mineral (MM). As médias de consumo de suplemento dos animais F1 foram de 206,1; 145,9 e 73,1g/dia, e as dos animais Nelore, 236,0; 205,1 e 94,3g/dia para os tratamentos AM, UR e MM, respectivamente. Para os novilhos Nelore, houve efeito (P
