Natural pastures from northeastern Argentina reveal seasonal nutritional deficiencies. The objective of the trial was to verify the effects of an injectable commercial formulation consisted of minerals, vitamins and proteins, in 18 months old Braford steers (160-200 kg liveweight). Three groups of 10 animals each were submitted to the assay. Group 1 received 3 applications of 10 ml SC every 22 days, and group 2 the same dose every 32 days. Group 3 was used as a control. After 96 days weight gains of 53.9 kg (group 1), 44.8 kg (group 2) and 36.4 kg (group 3) were registered, without adverse effects. The assayed commercial formulation was more effective at a dose of 10 ml every 22 days.
