Success of several programed AI-breeding protocols including ovsynch

Comparison of plasma concentrations of estradiol-17β and progesterone, and conception in dairy cows with cystic ovarian diseases between Ovsynch and Ovsynch plus CIDR timed AI protocols.

The objectives of this study were 1) to determine the effects of adding a CIDR to the Ovsynch protocol on plasma concentrations of estradiol-17β and progesterone and conception in dairy cows with cystic ovarian diseases and 2) to examine associations among the estradiol-17β and progesterone concentrations and conception. Cows were diagnosed as having cystic ovarian diseases if they were found t...

Preliminary observation of mantis shrimp breeding success in captivity

Mantis shrimps (Crustacea: Stomatopoda) are potential aquaculture species as they are constantly fished from the wild to satisfy demands of the seafood industry. Breeding capacity of mantis shrimps in captivity is scarce and implies a gap in this area to achieve successful aquaculture practices for this species. A preliminary observation was conducted with locally obtained mantis shrimps Miyake...

Factors Affecting Breeding Success

Timing Ovulation in Ewes Treated with Ovsynch Different Times of PGF2 αInjection during the Breeding Season

This study was carried out at Sakha Animal Production Research Station, during the period from Oct., 2009 to Sept., 2010. Forty Rahmani ewes were divided into three treatment groups: the 1st, 2nd and 3rd treatment groups were intramuscularly injected (Day 0) with 1 mL GnRH analogue followed by an intramuscular injection with 0.7 mL PGF2α5 (G1), 6 (G2) or 7 (G3) days later. A second dose of 1 mL...

Treatment of Repeat Breeding of Iraqi Buffaloes Using Different CIDR Protocols

The present study was undertaken to examine the efficacy of a treatment regime using a controlled internal drug release (CIDR) device in conjunction with injections of gonadotropin releasing hormone (GnRH) and prostaglandin F2α (PGF2α) on conception rate of repeat-breeding Iraqi buffaloes. Data were collected from 100 buffaloeswith repeat breeding in Ninevehprovince housed at six private dairy ...
