Effect of P.G. 600 on the timing of ovulation in gilts treated with Regu-mate
… was enhanced by gonadotropin treatment (P.G. 600; Intervet America Inc., Millsboro, DE) in gilts fed a progestin (Regu-mate; Intervet America Inc.) compared with gilts receiving progestin alone. We hypothesized that P.G. 600 altered the timing of ovulation, therefore mating gilts 12 and 24 h …

A Comparison of Pregnant Mare Serum Gonadotropin and P.G. 600® to Improve Reproductive Efficiency in Sows
… study the effects of pregnant mare serum and P.G 600 on reproductive efficiency. Sows were randomly allotted to treatments. Sows were evaluated for age (# of parities), breed composition and body condition score. Three sows who shared all three fields in common were randomly treated with one of …

Using Commercially Available Hormones to Enhance Swine Reproductive Efficiency in Batch Management Systems
… available hormones (MATRIX® and P.G. 600®; Merck Animal Health, De Sota, KS) in a 5-week batch management system had a positive impact on reproductive efficiency in gilts and sows over the course of 3 parities. Gilts were allocated to an Entry Group (A, B, or D) and then assigned to a …

Melatonin administration during the follicular phase and early pregnancy to minimize seasonal infertility in swine
… All gilts received an i.m. injection of P.G. 600, fence line boar exposure, and artificial insemination at estrus. Following P.G. 600, ovaries were assessed by ultrasound and reproductive tracts collected to assess pregnancy, litter size, fetal and placental measures at 33 days of gestation. …

Feeding strategies to enhance gilt reproduction and subsequent longevity and productivity in the breeding herd
… by FB in any of the experiments. Further, P.G. 600 did not hasten the onset of puberty, irrespective of FB in experiment 2. In experiment 3, ovulation rate was numerically greatest for flushed gilts, and was significantly greater than RS gilts (P = 0.05). The ovulation rate for flushed gilts was …
