Timing Ovulation in Ewes Treated with Ovsynch Different Times of PGF2 αInjection during the Breeding Season
This study was carried out at Sakha Animal Production Research Station, during the period from Oct., 2009 to Sept., 2010. Forty Rahmani ewes were divided into three treatment groups: the 1st, 2nd and 3rd treatment groups were intramuscularly injected (Day 0) with 1 mL GnRH analogue followed by an intramuscular injection with 0.7 mL PGF2α5 (G1), 6 (G2) or 7 (G3) days later. A second dose of 1 mL...
متن کاملEfficacy of CIDR or FGA Sponges with hCG Treatments on the Conception Rate and Prolificacyin Lori Ewes Out of the Breeding Season
Two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of eCG and subsequent hCG treatment on the reproductive performance of estrus-induced mature Lori ewes. In the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (FGA) sponges or Controlled Internal D...
متن کاملارزیابی عملکرد تولیدمثلی میش‌های افشاری با استفاده از روشی کوتاه مدت در هم زمانی فحلی در خارج از فصل تولیدمثلی
Estrus synchronization is a valuable management tool that has been employed in enhancing reproductive efficiency in ewes. This study was conducted to investigate the reproductive performance of ewes with short and long-term estrous synchronization programs accompanied by eCG or GnRH during the non-breeding season. A total of 48 Afshari ewes were randomly selected and divided into two groups. In...
متن کاملThe Effect of Post-lambing Interval on Fertilisation in Lactating Ewes Treated with Progestagen Impregnated Sponges and Gonadotrophin
For Border Leicester x Merino ewes joined in October in their normal anoestrous period at 5 and 8 weeks post partum, the percentages raddled by rams within seven days after sponge removal were 78 and 82. The percentages of ewes with fertilised eggs (of raddled ewes yielding eggs) were 27 and 70. In Merino ewes joined at 4 and 8 weeks post partum, in July, the percentages of raddled ewes were 97...
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. ...
