ResumoO objetivo desse experimento foi avaliar o efeito da suplementação com cromo orgânico sobre o peso corporal e ganho de peso de bovinos da raça Nelore. Utilizaram-se 20 bezerros, inteiros, com peso inicial de 179 kg e 6 meses de idade, distribuídos ao acaso em dois tratamentos com 10 animais, sendo um grupo controle e outro suplementado com cromo orgânico (1mg de cromo na forma de carboaminofosfoquelato de cromo), veiculado em sal mineral com estimativa de consumo em torno de 50g/bezerro/dia. O lote controle recebeu o mesmo sal mineral sem o cromo, com a mesma estimativa de consumo. Ambos foram fornecidos ad libitum e os animais mantidos em piquetes de Brachiaria brizantha e B. decumbens, em forma de rodízio durante 348 dias. Para avaliação do ganho de peso, os animais foram pesados após 14 horas de jejum de alimentos sólidos e líquidos, a cada 10 dias nos primeiros 40 dias de experimento e após, a cada 28 dias. A suplementação com Cr orgânico em bovinos Nelore influenciou (P<0,05) o peso corporal aos 210 dias, sendo 258,2 kg e 252,28 Kg para o grupo suplementado com cromo orgânico e controle, respectivamente.

Twenty calves were used, with initial weight of 179 kg and 6 months of age. They were distributed in two groups, being 10 animals per group. The experimental group received an organic chromium (1mg of carboaminofosfoquelato of chromium) per day. The mineral salt consumption was estimated for 50g/animal/day. The animals in the control group received the same mineral salt without chromium, in the same consumption. The mineral salt was furnished ad libitum and the animals were maintained in pickets with Brachiaria brizantha and B. decumbens pasture, with rotation during 348 days. For weight gain evaluation, the animals were weighed after 14 hours of solids and liquids fast, every 10 days in the first 40 days of the experiment. After this, steer weights were recorded at 28 days intervals. The organic Cr supplementation in Nelore steers there was influence (P<0.05) in the body weight it was on day 210, 258.2 kg and 252.28 kg for the organic chromium supplemented and for the control group, respectively.
