In this edition of Dairy Science digest Professor Mike Coffey, a researcher from the Scotland, describes the advancements with inline milk sampling. He explains how improvements in technology allows us to analyze subtle changes in the milk. These subtle changes occur with pregnancy, disease, metabolic disruptions and even to differentiate efficient cattle from the less efficient.

This non-invasive data collection opportunity could radically transform the information we could use to manage our herd.

Dairy Science digest covers the most current topics being published in the Journal of dairy science. Designed to never exceed :20, this podcast provides the “need to know” information for dairy producers with boots on the ground.

This episode highlights: “Predicting pregnancy status from mid-infrared spectroscopy in dairy cow milk using deep learning” is in press in the #journalofdairyscience and can be accessed here: https://doi.org/10.3168/jds.2020-18367

This episode we learn from Dr. Bradley Heins, from the University of Minnesota, all about integrating solar into your dairy grazing operation. He has learned about construction considerations, cow cleanliness and the shading effect of solar panels added to a rotational system.

His research titled "Evaluation of solar photovoltic systems to shade cows in a pasture-based dairy herd", is in press in the Journal of Dairy Science volume 104.

On this episode of Dairy Science Digest Fayth Kumro, MS Animal Sciences from the University of Missouri discusses Flashmate. This heat detection device uses touch screen technology to determine when your cows are in heat. Her research was conducted in both grazing operations and confinement. 

Learn more about how to affordably improve heat detection in your herd to keep your cows in the most productive phase of lactation.

Dairy Science Digest's Reagan Bluel interviews Dr. Chad Dechow, Geneticist from Penn St., to discuss the sweet spot in heifer development for the 7th episode of Dairy Science Digest.

This 15 year research project supported that the biggest heifers aren't the most profitable for your operation. Heaviest heifers are 49% more likely to be culled at a given time.

Moderate sized heifers that reach between 73-77% mature rate at first calving can produce more milk WITHOUT  sacrificing long term milk yield and herd life.

Dairy science digest #5 interviews Taylor McWhorter, from Georgia, to discuss considerations when selecting beef sires for your breeding program. Specifically focusing in on sire conception rates or SCR.

Journal of Dairy Science, Sept 2020. Title: Investigating conception rate for beef service sires bred to dairy cows and heifers.

In this edition of Dairy Science Digest, Stan Moore from MI State provides us insight to what employees (both hired and family) need to feel committed to your farm. Quality relationships are easy to develop, as long as your mindful of your approach. Listen in to catch nuggets of critical information to meet your farm where you are in the stage of workforce development.

In this edition Reagan Bluel interviews Dr. Jimena Laporta, from the University of Florida, about heat stress in your dry cow herd.

We've learned, from a decade of data, that heat stress on a dam during the dry period causes a change to her calf that last a lifetime and is passed down to her offspring. This change causes decreased milk production, productive life and profitability. Listen in to learn how a small investment in prevention can have a huge return.

Dairy Science digest is a monthly podcast developed to share current research in Dairy Science. The "need to know" info to help manage your herd. This month, Dr. Richard Chebel, from the University of FL discusses the effect of bringing SCR collars into a high producing Holstein herd in FL.This research looked at using the activity collars for conventional AI, TAI and to better refine the window for your ET program. See https://doi.org/10.3168/jds.2019-17892.
