CLOCK genes regulate circadian rhythm and reproduction in cattle

High expression of CLOCK genes – which influence an animal's circadian rhythm – can also influence fertility.

November 15, 2022

Infertility is the number one reason for culling on dairy operations. This is partially due to genetic selection and management for higher-producing cows, which has depressed fertility by increasing metabolic stress and blood circulation, among other mechanisms.

How do beef embryos measure up?

Price, demand and quality factor into using beef in your herd. Beef embryos offer several marketing options at higher value than traditional beef-on-dairy calves.

Dairy’s role in the beef industry cannot be overstated. Dairy cows, steers and heifers make up 18%–22% of U.S. beef. This percentage depends on the size of the native beef herd and its contribution to the beef supply, as well as how many dairy cows change careers.

Timing embryos with high-quality, prepared recipients

Analyzing donor and recipients, viewing IVF as an extension of your current protocol, accurately confirming pregnancies and working with your veterinarian can ensure a successful IVF program.

Most dairy farmers labor under a strict routine they feel comfortable with. This comfort reaches well beyond daily milking parlor tasks and affects cattle breeding programs, likely touching on some variations of heat detection, estrus synchronization, artificial insemination (A.I.) and potentially in vitro fertilization (IVF), followed by embryo transfer (ET).

Sensing stressors: Reproduction on your dairy

In my previous article about reproductive data and decision-making, I wrote about going back to basics and challenging your farm’s norms. I encouraged readers to find the Band-Aid solutions on their farms and prioritize what should be exposed and fixed.

The relationship between a herd’s environment and genetic potential

As producers implement genomic testing into their management strategy, the tie between a herd’s environment and a herd’s genetic potential can’t be overlooked. Great management programs can result in more valuable and action-oriented genomic information.

If I had written a book predicting the past two years in dairy farming, it would have been coined as fiction. In addition to a global pandemic, nobody could have predicted the wild swings in commodities coupled with the challenges in weather.

Accelerating genetic selection and maximizing IVF investment in dairy herds

February 28, 2022

As dairy farmers aim to accelerate the genetic progress of their herds, in vitro fertilization (IVF) leads the way in efficiency of quick genetic improvement, allowing producers to capitalize on their best genetics, and shorten generation intervals, while not disrupting the reproduction program of their herd. Rather than just milking the same cow, IVF allows for transformative differentiation in a herd without the need to liquidate and start over. Simply put, an average milking shed can progress genetics monumentally with one positive IVF mating.

Reproductive success may be sweeter than you think

Sydney Moore

The reproductive health of dairy cows is one of the most important factors influencing dairy herd efficiency. As we continue to genetically select our cows to produce higher quantities of milk, research has shown that we are inadvertently decreasing cow fertility as we prolong the calving interval to maintain this high production.

Insider tip: Don’t overspend on sexed semen

Mandy Schmidt

Your sexed semen costs might be higher than they should be, but not because your A.I. sales representative is deceiving you. Many dairies overspend on the volume of sexed semen purchased.
