Efficacy of Ovsynch protocol in cyclic and acyclic Egyptian buffaloes in summer
Animal Reproduction Science, 2010The aim of the present study was to evaluate the efficacy of an Ovsynch protocol in the cyclic and non-cyclic Egyptian buffaloes in the summer. The present study was carried out on 21 Egyptian pluriparous buffalo cows (11 cyclic and 10 acyclic) and 8 heifers (5 cyclic and 3 acyclic). All animals were administered 100 microg GnRH i.m.

In this study, there was evaluation of pregnancy per AI (P/AI) as a result of the first postpartum AI following four ovulation-synchronization treatments. Treatment regimens were Ovsynch-56 (OVS, n = 875; GnRH1-7d-PGF2α-56h-GnRH2-16h-FTAI), CIDR-OVS (n = 1001; OVS plus CIDR inserts between GnRH1 and PGF2α), Double-Ovsynch (DOVS, n = 663; imposing Pre ...

Ovsynch efficiency in anoestrous dairy goats
2017Oestrus induction and synchronization protocols in small ruminants are mainly based on the use of progestagens and eCG, comprising AI during and out of the sexual season. These methods result in acceptable kidding rate, but there is a worldwide intention of avoiding use of steroid hormones for oestrus synchronization due to micro residues in food chain.

Use of Ovsynch in dairy herds—differences between primiparous and multiparous cows
Animal Reproduction Science, 2004Ovsynch protocols are used to increase service rate and decrease days open and cullings for infertility. Recent reports have indicated better results after Ovsynch in primiparous than in older cows. However, this was not observed in all investigations on the subject.

This study was carried out to compare effects on the pregnancy rates achieved by timed AI (TAI) of cosynch, ovsynch and cosynch+ovsynch protocols in lactating dairy cows (60 d postpartum) and heifers (16-18 m old) in which the state of estrus is not determined.

The current study utilized 20 postpartum anestrus buffaloes maintained at an organized dairy farm in Vuyyuru, Krishna district to compare the metabolic (glucose), mineral (calcium) and anti-oxidant (superoxide dismutase) levels in ovsynch-48 (n=10, G48) and ovsynch-56 (n=10, G56) postpartum anestrus graded Murrah buffaloes.

OvSynch-Verfahren bei optimal und unterkonditionierten Braunviehkühen
2007In vorliegender Studie wurde das Synchronisationsverfahren (OvSynch) unter schweizerischen Verhältnissen bei Braunviehkühen untersucht. Insbesondere ging es um die Abklärung, inwieweit die Körperkondition den Erfolg dieser Methode beeinflussen kann. Die Untersuchungen wurden mit 40 optimal konditionierten Kühen (OK, Rückenfettdicke 28-35 mm) und 40 ...
