The objectives of this study were to evaluate the effects of flunixin meglumine (FM), an inhibitor of PGF2α synthesis, administered at the time of embryo transfer (ET) and insertion of an intravaginal progesterone-releasing device (CIDR) at the time of ET on pregnancy rates (PR) and the resynchronization of estrus. Beef cows (n = 796) and heifers (n = 108) at three locations were assigned rando...

This memo discusses the strategy for address assignment of the existing 32-bit IPv4 address space with a view toward conserving the address space and limiting the growth rate of global routing state. This document obsoletes the original CIDR spec [RFC1519], with changes made both to clarify the concepts it introduced and, after more than twelve years, to update the Internet community on the res...

Administration of exogenous melatonin (MEL) and progesterone (P4) in conjunction with follicle stimulating hormone (FSH) affects the number of developing follicles and oocyte quality in the anestrus ewe. Crossbred Rambioullet x Targhee Western range ewes (n=25) were randomly assigned to four treatment groups in a 2 x 2 factorial design [+/-MEL and +/CIDR device; MEL/CIDR, CIDR, MEL, and Control...

38 Lactating dairy cows (n=1,538) were enrolled in a randomized complete block 39 design study to evaluate protocols to synchronize estrus and ovulation. Within each 40 herd (n=8), cows were divided into three calving groups: EARLY, MID and LATE 41 based on days in milk (DIM) at mating start date (MSD). EARLY calving cows 42 (n=1,244) were  42 DIM at MSD, MID calving cows (n=179) were 21 to 41...

Malaria vaccination is an essential approach to combat malaria. One major protein studied for vaccine development Plasmodium falciparum erythrocyte membrane protein-1 (PfEMP1). It contains several important domains malaria pathogenesis. The binding of Cysteine-rich interdomain region ?1 (CIDR?1) PfEMP1 endothelial C receptor (EPCR) associated with cerebral malaria, while CIDR?1 CD36 has been co...

We determined whether an ovulatory estrus could be resynchronized in previously synchronized, AI nonpregnant cows without compromising pregnancy from the previous synchronized ovulation or to those inseminated at the resynchronized estrus. Ovulation was synchronized in 937 suckled beef cows at 6 locations using a CO-Synch + progesterone insert (controlled internal drug release; CIDR) protocol [...

Ghezel sheep is one of the main breeds in the north-west of Iran which is reared for meat, milk and wool production. Improving reproduction of this breed will have a significant impact on the economic development of local farmers. Therefore, in the present study the effect of simultaneous use of estrus synchronization(controlled internal drug releasing (CIDR) and equine chorionic gonadotropin (...

A total of 35 crossbred goats were used to evaluate the effect of oFSH dosages on ovarian responses during superovulation. CIDR was inserted for 10-15 days and were divided into 3 groups, namely Groups M,, M2 and S receiving 8.8 mg and 14.08 mg of oFSH through multiple intramuscular (i.m.) injection starting from 2 days before the CIDR removal and 8.8 mg of oFSH through single i.m. injection up...
