Effect of Double-Ovsynch and Presynch-Ovsynch on postpartum ovarian cysts and inactive ovary in high-yielding dairy cows. [PDF]
Front Vet SciIntroductionOptimizing the management of dairy cattle reproduction can reduce postpartum ovarian disease in high-yielding dairy cows and thus enhance ranch economic benefit. The hypothesis of this study was that the Double-Ovsynch (DO) protocol in high-producing dairy cows would result in a lower incidence of follicular cysts but a higher incidence of ...

Pakistan Journal of Zoology, 2019 Appropriate postpartum reproductive management plays a vital role in dairy farm economics. Primary objective of the present study was to compare the efficiency of standard Ovsych protocol (OVP0) and its modified forms (OVP5 and OVP7) as postpartum reproductive management tools in cyclic dairy cows. In total, 167 Holstein cows were randomly divided into

The Journal of Reproduction and Development, 2019 This study aimed at investigating the efficacy of two protocols of estrous synchronization on follicular changes and hemodynamics. Pluriparous Egyptian buffaloes (n = 36) were synchronized either with controlled internal drug release (CIDR)-PGF2α (7-days

Timed artificial insemination protocols in dairy cattle: Functioning, shortcomings, and improvements
Czech Journal of Animal Science, 2023 Oestrus detection is currently at the top of the factors limiting the success of artificial insemination in dairy herds. This limitation becomes more pronounced as milk production increases because of higher metabolic clearance rates of steroid hormones ...

Ovsynch synchronization and fixed-time insemination in goats
Theriogenology, 2008 This study assessed the efficacy of an Ovsynch protocol (vs. the classical cronolone containing vaginal sponge+eCG treatment) to generate fixed-time insemination in goats during the breeding season. Each regimen was applied to 24 Boer goat does. Onset and duration of estrus were determined with an aproned male and follicular development was monitored ...
