the objective of this study was to evaluate three methods of estrous synchronization, viz. controlled internal drug releasing device (cidr), intravaginal sponges impregnated with fluogestone acetate (fga), and cloprostenol (estrumate; an analogue of prostaglandin f2α) in nadooshani goats of yazd province, iran.the estrous synchronized does (n = 30 to 33 per treatment), after heat detection, wer...

This experiment was carried out on 123 Farahani ewes from a herd in Delijan city in Markazi province of Iran to determine the best short-term method for oestrus synchronization. Ewes were divided into five experimental groups randomly: group 1) use of controlled intervaginal drug release devices (CIDR) for 7 days with intramuscular (IM) injection of PGF2α on zero day and IM injection of 500 IU ...

The bacterial flora of the vagina ten ewes was determined at sponge removal and two days later before insertion fluorogesterone acetate intravaginal sponge. Using E. coli as a marker to species, there significant increase (P<0.05) in population when samples taken were compared, but (P<0.01) decrease season Hertfordshire, England compared later. There no difference (P>0.05) with after r...

A total of 2567 indigenous Greek ewes (Chios, Vlachiki and VlachikixChios breeds) were used to determine the optimum time for insemination, following synchronization of oestrus with MAP-impregnated intravaginal sponges and PMSG during non-breeding season. Within each breed group, the ewes were divided into three subgroups and submitted to a double blind cervical artificial insemination 48 and 6...

ABSTRACT This study was performed during the anestrous, involving 140 Akkaraman Kangal ewes whose lambs had died in neonatal stage due to pneumonia and enteritis. Intravaginal sponge containing progesterone placed animals (Group 1, n = 70) on day 0 removed after 7 days, following which 263 µg PGF2α 500 IU eCG were administered sheep. Ram introduction for days (days 8-14), starting from removal ...

The use of the CIDR (controlled internal drug release) dispenser as a progestagen-synchronizing agent was evaluated in 37 Karakul ewes during the breeding season, using the intravaginal progestagen sponge as a control (30 ewes). Although there was no significant differences in oestrous response, following intravaginal insertion for 14days, between these two progestagen devices, the time from de...

Abstract The management of sheep reproduction requires the induction and synchronization estrus cycle ovulation for ewe out-of-season and/or synchronized lambing. These managements are based on insertion an intravaginal device controlled internal drug release (CIDR or sponge) then administration a hormonal injection, such as PMSG, eCG, hCG, GnRH. This study aimed to compare impact CIDR sponges,...

A group of Southdown ewes (n=lll), two years and older, which had been maintained in isolation from rams had intravaginal sponges (Repromap, Upjohn) inserted on 18 Dee (day 0). On day 10 after sponge insertion rams (10%) were introduced to the ewes and at sponge withdrawal on day 12 they were harnessed and the ewes were allocated at random to PMSG treatment. The doses of PMSG were 0, 100, 200, ...
