The average weaning rate of lambs in the state of Rio Grande do Sul is around 60%, making the activity uncompetitive due to the low scale of production. In addition, part of the crop of weaned animals does not reach the end of life at a young age (lamb category), which devalues ​​the product to the consumer. Thus, the study of different animal nutrition techniques for this category is justified, in order to make sheep farming more profitable. In this sense, the present work had as objective to evaluate the effect of the supplementation through the creep feeding system on the performance of a production system of lambs Australian Merino x Ideal, managed on native field. The experiment was conducted in the municipality of Santana do Livramento and covered the period from July to December 2020. The variables final weight (FW) of the treatment and control groups after the period of supplementation, average daily gain (ADG) between groups and body condition score (BSC) of sheep after weaning. There was an effect of the treatment for both males and females, for the variables final weight and average daily gain. The sheep's body condition score was not influenced by the creep feeding system. The system of raising sheep under creep feeding promotes an increase in the weight and growth speed of lambs, presenting itself as an alternative to intensify sheep farming.
