PMSG profiles in superovulated and anti-PMSG antiserum treated mice and heifers with enzymeimmunoassay.
A sandwich enzymeimmunoassay (EIA) for pregnant mare serum gonadotropin (PMSG) using a microtiter plate was developed. Sensitivity of the assay to PMSG was 15.6 mIU/ml (0.2 ng/well). The PMSG levels in serum were measured with the EIA in superovulated and anti-PMSG rabbit antiserum treated mice and heifers. In mice, the PMSG blood level was measurable in the serum 4-6 days after intraperitoneal...
متن کاملInfluence of breed and season on ovarian and pituitary response in progestogen-PMSG-treated ewes.
Breed and seasonal effects on LH release, ovarian steroid secretion, and ovulation were evaluated in mature Finnish Landrace (Finn) and Hampshire ewes that received either a progestogen-PMSG treatment in May, July and November (experiment 1) or estradiol-17beta (50 microg) in May and July (experiment 2). The progestogen-PMSG treatment increased plasma estradiol within 12 hr after the PMSG injec...
متن کاملThe Effect of Pmsg Dose on Corpora Lutea and Embryo Numbers in Gilts
Superovulation in donors is an important factor influencing ovulation rate and embryo recovery. Crossbreed pubertal gilts (n=376) treated from year 2005 to 2009 were used as embryo donors. Experiment was evaluated in two parts: In the first part (I) gilts were divided into two groups with different synchronization schedules. In the first group (R+) 265 gilts were treated with Regumate Porcine (...
متن کاملStudy of Reproductive Performance of Crossbred Ewes Treated with GnRH and PMSG during Breeding Season
Reproductive performance was evaluated in non-lactating crossbred ewes to which were administered the exogenous GnRH and PMSG. The ewes were randomly allocated in three treatment groups (n=40).After accurate detection of estrus and 2 hours prior to mating, 2.5 mL of distilled water and 2.5 mL of GnRH were injected intramuscular to each ewe of the first (control) and second group, respectively. ...
متن کاملInduction of abortion in mares with equimate: effect on secretion of progesterone, PMSG and reproductive performance.
Thirty-two light-horse mares were confirmed to be pregnant and assigned to one of four treatments: (1) injected with 250 micrograms of Equimate on day 70 and again on day 77 if abortion had not occurred; (2) injected with 250 micrograms of Equimate on day 70 and every 24 hr until abortion occurred (maximum four injections); (3) injected with 250 micrograms of Equimate on day 70 and every 12 hr ...
