Eazi-BrEEdTM CIDR® Cattle Insert for Induction of Estrous Cycles in Anestrous Lactating Dairy Cows
Though conception rates within 2 weeks of Eazi-BrEEd CIDR removal were lower for treated cows (27.7% vs 36.2% for controls, P < 0.083), overall pregnancy rates did not differ between treatment groups (P = 0.32). [Conception can be reduced by: 1) an older, unknown-aged egg being ovulated after an extended progesterone period; 2) vaginitis, so cleanliness and proper insertion technique are impo...
متن کاملNevada REVIEW OF ESTRUS SYNCHRONIZATION SYSTEMS : CIDR
The CIDR is an intravaginal progesterone insert, used in conjunction with other hormones to synchronize estrus in beef and dairy cows and heifers. The CIDR was developed in New Zealand and has been used for several years to advance the first pubertal estrus in heifers and the first postpartum estrus in cows. The CIDR is a “T” shaped device with flexible wings that collapse to form a rod that ca...
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 کاملComparison of Different Methods of Oestrus Synchronization on Reproductive Performance of Farahani Sheep in Iran
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 ...
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...
