Systematic Synchronization and Resynchronization Systems for Reproductive Management of Lactating Dairy Cows
نویسنده
چکیده
Introduction Reproductive physiologists had long searched to develop a synchronization program that could overcome the problems and limitations associated with visual estrus detection. Such a program was developed at the University of Wisconsin-Madison in 1995 (Pursley et al., 1995) and is now commonly referred to as Ovsynch. Ovsynch synchronizes follicular development, luteal regression and ovulation such that artificial insemination can be conducted at a fixed-time without the need for estrus detection. Subsequent studies that repeated this work soon verified the results of the original publication (Burke et al., 1996; Pursley et al., 1997a,b), and dairy producers soon began to implement the Ovsynch protocol as a tool for reproductive management.

Strategies for Resynchronization of Ovulation and Timed AI
Many confinement-based dairy systems in the U.S. have adopted systematic synchronization protocols and timed artificial insemination (TAI) for submitting cows for first postpartum AI service (Caraviello et al., 2006). Although reliance on synchronization of ovulation and TAI for improving service rate to first AI service reduces the impact of poor estrous detection, the improved AI submission r...
متن کاملReproductive Challenges of High Producing Dairy Cows
Within a dairy herd, total milk production is determined by the proportion of cows producing milk at any given time and the level of milk production of the individual cows within the herd. Improving reproductive efficiency helps to maintain the maximal number of cows producing milk at optimal levels. Reproductive efficiency in dairy cattle currently is suboptimal primarily due to four factors: ...
متن کاملThe effect of Zataria multiflora extract on the clinical endometritis and reproductive indices in lactating Holstein dairy cows
In the present study, the effect of intrauterine infusion of Zataria multiflora extract on the clinical endometritis was investigated. Vaginal examination, transrectal palpation and ultrasonography were used to inspect the genital tract at 30-40 days in milk and two weeks later the same approach was applied. Cows with clinical endometritis were randomly divided into three treatment gro...

Considering different fertility traits 411 cows from 73 farms used for economic analyses. From these, 202 lactating cows were selected for evaluating the fertility status. Pre-tested data sheets were used to record the socioeconomic status of the farms including their assets, cost and return and productive and reproductive performance of the dairy cows. Targets were set considering the situatio...
متن کاملComparison of two estrus synchronization and resynchronization treatments in lactating dairy cows.
Reproductive performance in cows following synchronization of estrus with intravaginal progesterone releasing devices (IVD) has varied with the length of treatment, cyclic status and prolonged return to estrus intervals in some cows following first AI. The objective of this study was to compare two methods of synchronizing and resynchronizing estrus on the reproductive performance of lactating ...
