Resumo: With the purpose of studying the effect of biostimulation on reproductive traits, 82 primiparous beef cows were distribuited into two treatment groups: biostimulated (BE) or not (NE) by teaser bulls during 83 days before the breeding season. Before the start of artificial insemination period, accumulated cycling rates were 21 .05% (BE) and 6.81% (NE). Higher serum progestrone levels were observed in biostimulated cows, but response depends on nutritional status (body condition score). When associated with weaning before the start of insemination period, biostimulation did not affect pregnancy rate (BE=97.38%; NE=100%), mean insemination julian date (BE=332.9; NE=333.21), nor repeat breeding rate (BE=21%; NE=19%).

Antes de iniciar a inseminação artificial, as taxas acumuladas de vacas ciclando foram de 21,05% (BE) e de 6,81% (NE). Maiores concentrações sé ricas de progesterona foram observadas nas vacas bioestimuladas, sendo a resposta dependente do status nutricional (condição corporal). Quando associada ao desmame no início da inseminação artificial, a bioestimulação não apresentou efeito sobre a taxa de prenhez (BE = 97,38%; NE = 100%), data juliana média de inseminação (BE = 332,9; NE = 333,21), nem no percentual de retorno ao cio (BE = 21%; NE = 19%).Editora da Universidade Estadual de Maringá2008-02-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/60210.4025/actascianimsci.v28i4.602Acta Scientiarum.
