Resumo: Age of puberty was evaluated in heifers (Crioula Lageana Breed) submitted to two post-weaning feeding systems, in the Santa Catarina Plateaus, Brazil. This study was composed of: Treatment I, in which nine animals were maintained in cultivated pasture during the winter, and Treatment II, in which nine animals were maintained in natural pastures during the whole period of the experiment. In both treatments, animals received mineral supplementation. Daily observations of estrus behavior were made. All animals were submitted to rectal palpation and ultrasound exam; blood samples were taken weekly and all the animals were weighed monthly. Puberty was characterized by the first estrus, with or without oestrus behavior, confirmed by the formation of the corpus luteum and plasmatic concentrations of progesterone by radioimmunoassay (RIA) over 1ng/ml, in two consecutive samples.Using cultivated pastures for Crioula Lageana heifers after weaning, in the winter, advanced their age of puberty. The results showed that 15-month-old animals weighing approximately 300kg are ready for reproduction.

Foi avaliada a idade à puberdade de novilhas da Raça Crioula Lageana submetidas a dois sistemas de alimentação após o desmame na região do planalto catarinense. O estudo foi composto por: Tratamento I, em queforam avaliadas nove novilhas mantidas em pastagens cultivadas durante o período de inverno, e Tratamento II, no qual nove novilhas permaneceram durante todo o período em pastagem natural, tendo ambos os tratamentos recebido suplementação mineral. Observações diárias de comportamento de estro foram realizadas. Todas as novilhas foram submetidas a palpação transretal, exame ultrassonográfico, colheitas de amostras sanguíneas semanais e pesagens mensais. A puberdade foi caracterizada pelo primeiro estro ovulado, acompanhado ou não de sinais externos, confirmado pela formação de corpo lúteo e concentrações plasmáticas de progesterona acima de 1ng/ml, em duascolheitas consecutivas. A alimentação com pastagem cultivada de inverno antecipou a puberdade. Os resultados permitem concluir que novilhas da raça Crioula Lageana com 15 meses de idade e aproximadamente 300kg de peso vivo estão aptas à reprodução.
