Review of Estrous Synchronization Systems : Cidr
The CIDR is an intravaginal progesterone insert, used in conjunction with other hormones to synchronize estrous 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 c...
متن کاملEfficacy of CIDR, fluogestone acetate sponges and cloprostenol for estrous synchronization of Nadooshani goats during the breeding season
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...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولApplication of the CIDR-B to Estrous Synchronization in Beef Cattle
Progesterone, or progesterone like compounds, (progestins) have been investigated and used for estrous synchronization for several decades. However, the success rates of programs that use progestins have varied considerably. A primary challenge to the use of this hormone for synchronization was the repeated observation in the past of reduced fertility at the synchronized estrus. Perhaps of even...
متن کاملProduct Development for Estrous Synchronization : Beef Cattle
Physiological principals underlying synchronization of estrus identified 1) hormones naturally controlling the estrous cycle of cattle, 2) hormones commercially available, 3) mode of action of the hormones commercially available, and 4) when/how they might be used to manage estrus and breeding of beef cattle. The products available are progestogens (melengestrol acetate (MGA) and progesterone d...
