Resumo: | 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. |

Además, uma parte de animales destetados no llega al final de la vida a una edad temprana (categoría cordero), lo que devalúa el producto para el consumidor. Así, se justifica el estudio de diferentes técnicas de nutrición animal para esta categoría, con el fin de rentabilizar la ganadería ovina. En este sentido, el presente trabajo tuvo como objetivo evaluar el efecto de la suplementación a través del sistema de creep feed sobre el desempeño de un sistema de producción de corderos australianos Merino x Ideal, manejados en campo nativo. El experimento se realizó en el municipio de Santana do Livramento y cubrió el período de julio a diciembre de 2020. Las variables evaluadas fueron el peso final (PF) de los grupos tratamiento y control después del período de suplementación, ganancia diaria promedio (GMD) entre grupos y puntaje de condición corporal (PCC) de las ovejas después del destete. Hubo efecto del tratamiento tanto para machos como para hembras, para las variables peso final y ganancia diaria promedio. La condición corporal de la oveja no fue influenciada por el sistema de alimentación. El sistema de cría de ovinos en alimentación por creep promueve un aumento del peso y velocidad de crecimiento de los corderos, presentándose como una alternativa para intensificar la ganadería ovina.Os índices médios de desmame de cordeiros no estado do Rio Grande do Sul giram em torno de 60%, tornando a atividade pouco competitiva pela baixa escala de produção. Além disso, parte da safra de animais desmamados não chega a terminação em idade jovem (categoria de cordeiro), o que desvaloriza o produto frente ao consumidor. Assim, justifica-se o estudo de técnicas de nutrição animal diferenciada para esta categoria, no intuito de tornar a pecuária ovina mais rentável. Neste sentido, o presente trabalho teve como objetivo avaliar o efeito da suplementação através do sistema creep feeding sobre o desempenho de um sistema de produção de cordeiros Merino Australiano x Ideal, manejados sobre campo nativo. O experimento foi conduzido no município de Santana do Livramento e compreendeu o período de julho a dezembro de 2020. Foram analisadas as variáveis peso final (PF) dos grupos tratamento e controle após o período de suplementação, ganho médio diário (GMD) entre grupos e escore de condição corporal (ECC) das ovelhas após a desmama. Houve efeito do tratamento tanto para machos quanto para fêmeas, para as variáveis peso final e ganho médio diário. O escore de condição corporal das ovelhas não foi influenciado pelo sistema de creep feeding. O sistema de criação de ovinos sob creep feeding promove incremento no peso e na velocidade de crescimento dos cordeiros, apresentado-se como uma alternativa para intensificação da pecuária ovina.
