The study was undertaken to compare the efficacy of an estradiol-17β + CIDR based protocol with the conventional ovsynch + CIDR based protocol for synchrony of wave emergence and ovulation in Murrah buffalos. In group I (n=25), on day 0 (beginning of experiment), buffaloes were administered a CIDR device (1.38 g P4) and concurrently received 1.5 mg E-17β. On day 9, the CIDR was removed and a pr...

the aim of this study was to determine the effects of ecg, pgf2α and gnrh hormone on improvement of reproduction performance of cidr synchronized zandi ewes in breeding season. 500 ewes with age of 2.5-4 years and same nutritional condition were selected for this study and received cidr for 12 days. then these ewes were assigned to five equal groups. first group received no hormone (control gro...

Based upon observations across a series of experiments that pregnancy rate to timed-AI was positively related to length of proestrus, the traditional 7-day CO-Synch + CIDR program was modified to allow an increased interval from PGF/CIDR removal to GnRH/timed-AI; resulting in the 5-day CO-Synch + CIDR program. This modification has been demonstrated to increase timed-AI pregnancy rates relative...

The use of the CIDR (controlled internal drug release) dispenser as a progestagen-synchronizing agent was evaluated in 37 Karakul ewes during the breeding season, using the intravaginal progestagen sponge as a control (30 ewes). Although there was no significant differences in oestrous response, following intravaginal insertion for 14days, between these two progestagen devices, the time from de...

In Exp. 1, 187 lactating beef cows were treated with injections of GnRH 7 d before and 48 h after prostaglandin F2alpha (PGF2alpha; Cosynch) or with Cosynch plus a 7-d treatment with an intravaginal progesterone (P4)-releasing insert (CIDR-B; Cosynch + CIDR). In Exp. 2, 183 lactating beef cows were treated with the Cosynch protocol or with Cosynch plus a 7-d treatment with norgestomet (Cosynch ...

Previously Broido and Claffy analysed the global Internet interdomain routing system based on BGP policy atoms: equivalence classes of prefixes based on common AS path as observed from a number of topological locations [6] [7]. In this report we define a variant of policy atoms, called declared atoms. Declared atoms constitute an aggregation mechanism complementary to CIDR aggregation. We descr...

published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. the present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. eighty afshari cycling ewes were synchronized during breeding season using cidr for 14 days and assigned to 4 groups (n=20); group 1 received a si...

An experiment was conducted to evaluate the efficacy of porcine follicle stimulating hormone (pFSH) dosage based on body weight (BW) on ovarian responses of crossbred does. Thirty donor does were divided into 3 groups getting pFSH dosages of 3, 5, and 8 mg pFSH per kg BW, respectively, and were named as pFSH-3, pFSH-5 and pFSH-8, respectively. Estrus was synchronized by inserting a controlled i...

We describe several experimental parameters and a parallelization technique used in our online document clustering system, CIDR. These modifications were introduced into CIDR to reduce the running time so that incoming documents be clustered in almost real time. We discuss how several of these parameters are justified on linguistic grounds and report preliminary quantitative results on the effe...

The aim of the present study was to investigate the endocrinology of periestrus period and the days after until estrus in ewes (n = 40) synchronized out of breeding season and diagnosing the related pregnancies after laparoscopic insemination comparing to different doses of PMSG that was used. Animals treated for 12 d with CIDR followed by administration with different doses (0, 450, 550, 650, ...
