Nevada 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 کاملOestrus synchronization and conception rate in Kedah-Kelantan cattle following treatment with CIDR-B and cloprostenol (Penyelarasan estrus dan kadar kebuntingan lembu Kedah-Kelantan selepas rawatan dengan CIDR-B dan kloprostenol)
The effectiveness of CIDR-B treatment for 12 days compared with the double injections of cloprostenol for oestrus synchronization in Kedah-Kelantan (KK) cows was evaluated. A total of 148 KK cows were used in three trials conducted at MARDI Research Station, Kluang, Johor. Cows were allocated randomly into two groups. Group 1 was given two injections IM of cloprostenol at 12 days apart; group 2...
متن کاملEstrus Synchronization and Pregnancy Rates of Beef Cows Administered Melengesterol Acetate the Ten Days before Estrus Synchronization with Syncro-mate B
treatments the cows were randomly assigned to two groups. One group of cows (n= 281) was fed 0.5 mg of melengestrol acetate (MGA) per head per day for ten days while the other group of cows (n= 257) served as controls. All cows were bled for progesterone concentrations at the beginning of the MGA feeding (d -21), before the SMB treatment, and at the time of artificial insemination (AI). Twenty-...
متن کاملLuteal lifespan and fertility after estrus synchronization in goats
The present experiment aims to examine the efficiency of estrus synchronization using progesterone and equine chorionic gonadotrophin (eCG) and to look at luteal function. During the non-breeding and breeding season, 5 adult female Korean native goats were injected intramuscularly with 2.5 ml of physiological saline as the control. A progesterone impregnated intravaginal sponge was then kept in...
متن کاملComparison of Two CIDR Synchronization and AI Treatments in Postpartum Lactating Bos indicus X Bos taurus Cows1,2
On d 0 of the experiment Bos indicus x Bos taurus (n=130) cows received an injection of GnRH and a progesterone-releasing device called an Eazi-BreedTM CIDR® for 7 d with a prostaglandin F2a injection at CIDR removal. Upon CIDR removal cows were divided into two AI treatments: 1) injection of estradiol cypionate (ECP) 24 h after CIDR removal with AI 8 to 10 h after a detected estrus and timed-A...
