Full Length Research Paper
This work has permitted to test the response of the local cattle Cheurfa for a pFSH superovulation treatment based on administration of 40 mg pFSH (LH/FSH 40%), at a rhythm of 2 injections every 12 h between J10 and J13 of the oestrus cycle associated to injection of prostaglandin synthesis "Prosolvin®" at the 3rd day of the treatment. Two inseminations were carried out at 12 h interval after observed oestrus. The embryos were collected at J7. With four tests carried out, the average number of corpus luteum and collected embryos obtained were respectively 7.5 and 5 per cow. The number of transferable embryos was 2.33 per cow, with a viability rate of 46.66%. Five fresh embryos were transferred in recipients improved breed from the embryos obtained. The pregnancy rate obtained was 60. 0% with 3 born calves Cheurfa type (2 male and 1 female).
Key words: Superovulation, embryo, transfer, cattle, local.
