| Summary: | In this study, the luteolytic effect and
pregnancy rate of Luprostiol administrated via different
routes and various doses in heifers were investigated.
Animals were divided info three experimental groups,
each inc!uding 5 heifers. Group 1 (intra muscular group,
(IMG), Group II (intravulvo-submucozal group, IVSMG),
Group III (intra ovarian group, lOG), were treated with
15 mg, 3, 75 mg and 0.75 mg Luprostiol respectively.
Luteoliytic response was monitored by measuring
plasma progesterone concentration.<p>
One animal specimen in each group has not s ho wed
any evidence of luteolysis while luteolysis in the rest of
the animals in IM and IO groups, there was a delay in
luteolysis in two animals in IVSM group. Plasma progesteron
levels decreased less than 1 ng/ml within 24
hours after PGF<sub>2</sub>α administration in IM and /0 groups
(0.22±0. 18, 0.74±0.39, respectively), however, it was
found higher in IVSM group (0.80±0.55 ng/ml) compared
to others. The appearance of estrous detected
through visual observation was between 49-72 hours in
IM and IVSM groups, whereas it was observed earlier
(24-36 hours) in IO group. All animals showed estrus,
artiiicialIy insemineted, of which the IO group had the
highest pregnancy rat e of 100%. |
