SUPEROVULATION OF GOATS WITH PURIFIED PFSH SUPPLEMENTED WITH DEFINED AMOUNTS OF PLH

摘要

The superovulatory response of goats treated with purified pFSH supplemented with 30, 40 or 50% pLH was compared. Sixty-four Beer goat does were synchronized by progestagen-containing ear implant, randomly allotted to 3 groups and, beginning 2 d before implant removal, treated with purified pFSH supplemented with 30, 40 or 50% pLH. Each animal received 16 Armour Units of pFSH administered in 6 descending doses at 12-h intervals. Along with the last 2 injections, the does received 5 mg PGF(2 alpha). Embryos were flushed either surgically or after slaughter on Day 5 or 6 after the last day of standing estrus.
