Well, it's that time of year for me to plead with our producers to
pregnancy diagnose their cows. This year appears to be even more
important than the last few. The University of Kentucky has about 2500
cows on various Applied Master Cattleman projects throughout the state.
Many of these farms have participated in these projects for two years.

An estimated 75 percent of North Dakota dairy producers use artificial insemination (AI) for impregnating heifers.
"Artificial insemination provides genetic advancement within the herd, such as conformation and milk production; ensures monitoring of semen quality and fertility of AI bulls; eliminates

- The CIDR is approved by FDA to synchronize estrus in dairy heifers. It is an effective method that is convenient to use.
- Alterations of the protocol to improve efficacy are being evaluated; however, only the approved

Beef heifers normally have their first estrous cycle between 12 and 15 months of age. The major factors delaying onset of puberty are poor nutrition or a genetic predisposition for late maturity. In order for heifers to calve at 24 months they must conceive by 15 months of age.
As heifers mature,

There are six steps to follow for improving the estrous detection rate in a particular herd.
These steps take into account the unique aspects of each herd’s management and the facilities for housing and exercise of cattle. The goal of these steps is to make the best possible use of the dairy producer

AMES, Iowa -- Advances in synchronizing the beef cow's estrus cycle continue to move forward, and the Iowa Beef Center at Iowa State University has worked to bring these latest efforts to cattle producers.
More than three decades ago, all producers had to work with were synchronization systems involving

The relatively new estrous synchronization technique being used in replacement heifers is the combined use of MGA and prostaglandin. Melengestrol acetate (MGA; Pharmacia-UpJohn Co.) is a feed additive commonly used in feedlot heifer rations to block cycling activity of the heifers. At this printing,

Research has provided many good options for synchronization of estrus and ovulation in the past few years. To simplify the process of protocol selection, a team of researchers, veterinarians, AI industry representatives and other industry partners have developed a short list of recommended protocols
