ABSTRACT
This study aimed to evaluate the effect of recombinant bovine somatotropin on the plasma levels ofprogesterone, estradiol, growth hormone and IGF-1. 8 cows Girolando were divided into three groups control,250 mg rbST and 500 mg rbST. Blood samples were collected 60 days prior to aspiration, in 12-day intervals,with the samples taken on the same days of rbST applications. For hormone measurements, ELISA commercialkits were used. The hormone concentrations were subjected to the normal pattern Cramer-von Mises and foraverage of comparison, the test Student-Newman-Keuls (SNK) was used, with 5% probability. It was notpossible to measure the plasma concentration of GH hormone. The rbST administration had no effect on plasmaconcentrations of progesterone, estradiol and IGF-1 among the groups treated with 250 mg and 500 mg and theuntreated group, there was also no significant variance between the days of application and OPUs.(AU)
