Abstract

We analized production originated from 255 embryo recovery Holstein heifers and cows Turing years 2001 to 2004. The animals were selected for production records and racial purity, and superovulated with Pluset or Foltropin. Superovulation was iniciated on day 9 after natural Oestrus (D0) using decresing doses of FSH intramuscularly (IM), applied every 12 hours for 4 days. On the third day of superovulation (D 12) was applied prostaglandin (Illiren) in the afternoon. Three artificial insemination (IA) were found and recovered the embryos seven days alter the first IA in a non-surgical process. The results suggested that the drug of superovulation used can influence the embryo quality obtained. The use of Plused enables production greater number of freezable embryos in heifers and Foltropin in the cows.
