In addition to dosage effect, it was found that ovulation rate of the pigs treated with 1.0 dose of PG600 was significantly lower than that of those injected with 1.5 and 2.0 doses of PG600. These conflicting reports and the expense of the drug leads us to the conclusion that further research is needed to investigate why greater numbers of sows express estrus, are mated, but then fail to farrow, before PG600 can be recommended for routine use in the sow herd. However, generally speaking, farrowing rates and litter sizes are often not improved, even though some reports indicate that greater numbers of pigs are produced when compared to untreated sows. P.G. PG600 given to sows at weaning induces an earlier return to estrus and delays time of ovulation relative to the onset of estrus. 2. For induction of estrus in prepuberal gilts and weaned sows experiencing delayed return to estrus.

PG600 contains a combination of two hormones that have been approved worldwide for use in swine for inducing estrus. Each single dose contains standardized biological activity of PMSG and hCG. However, for females that are anestrus 3 weeks after the 1st shot, a 2nd shot can be effective at inducing 50% of these gilts into estrus within a week. Initially, P.G.
