Abstract: The aim of this study was to determine the efficiency of a porcine pituitary gonadotrophin extract with a defined pLH content in the superovulation of sheep. Estrus was synchronized in 61 Polish Mountain ewes with intravaginal fluorogestone acetate sponges. Twenty-four hours before the sponges were removed, the ewes underwent different superovulatory treatments: Group I 250 IU of pFSH with 250 IU of pLH (n=19); Group II 500 IU of pFSH with 500 IU of pLH (n=19); and Group III 750 IU of pFSH and 750 IU of pLH (n=18). Gonadotrophine was administered intramuscularly twice a day over a 3-day period in decreasing dosages. A control group of ewes (n=5) was treated with saline. In most of the ewes estrus began about 20 hours after sponges were removed. All the ewes were bred naturally every 12 hours. Superovulation was confirmed in 75% of the treated animals. The ewes receiving 250 IU each of pFSH and pLH produced an average of 7.6 +/- 3.1 corpora lutea (CL), 6.3 +/- 2.4 ova and 4.3 +/- 4.1 transferable embryos. Group II (500 IU of pFSH and pLH) produced 8.5 +/- 4.0 CL, 7.6 +/- 4.1 ova, and 4.1 +/- 2.9 transferable embryos. Group III (750 IU each of pFSH and pLH) produced 8.3 +/- 5.2 CL, 7.5 +/- 5.5 ova and 5.2 +/- 5.1 transferable embryos. The mean embryo recovery rate was 87% for all three groups. Differences in superovulatory response and embryo recovery rate among the groups were not statistically significant (P>0.05). |
