Timestamps & Summary 1:42 John, in your experience, what are the top three characteristics of the most profitable dairy farms? Dr. John Ellsworth I would say number one, high milk production. Number two, I say a successful strategy is limiting the ratio of heifers to cows to 80% or 85%. And number three, solid cost control. When we talked about the high milk production, it doesn't matter how much...

Timestamps & Summary 01:44 Has the interest in dry matter intake changed over the years, especially in the light of discussions about feed efficiency?  Dr. Mike Hutjens The goal on dairy farms is to have healthy cows.  Dry matter plays an important role in animal health and immunity.  We have to get cows pregnant in a timely manner, because that determines a peak milk production. We are a little l...

Timestamps & Summary 01:33:00 – Why did you start researching B vitamins, a nutrient that was supposedly useless for the cow? And how did your original hypothesis change over the years? Dr. Girard started to think about B vitamins when she had to prepare a seminar and a review of literature during her PhD. Pregnant at the time and having to take folic acid supplement herself, she decided to conduc...

Timestamps & Summary 01:10:00 – Your shared with me a paper you wrote in 2016 that talked about the nutrition 2.0. Can you explain a little bit more of what you mean by it? We're referring to a new generation of understanding nutrients and how we should feed them. With the discovery in the Human Genome project that there are hundreds of sensors in the genome that are apparently designed to sense n...

Timestamps & Summary 01:54:00 – Could you explain the path you took to become who you are today? Dr. Hutjens grew up on a 70-cow grade Holstein farm in the 1950s. He went to a Community College for a year, and then down to Madison to get his degree, where he got a chance to work in a mastitis lab and in the dairy science department. When he met Dr. Jim Crowley and Dr. Dave Dixon, he fell in love w...

Timestamps & Summary 01:20:00 – In a previous episode, you expanded on your approach on farm synchronization to improve efficiency. Could you expand specifically on how the feed centre and mixing feed impact the overall farm synchronization? There is currently a great lost of efficiency when it comes to feed centres. To prevent that, David Greene developed what he calls a "feed-zone model concept"...

Today’s episode will discuss practical steps to minimize the incidence and severity of DD from the point of view of a leading expert, Karl Burgi.

We perhaps thought that with our high forage diets SARA was a thing of the past. The ability of individual cows to cope with variable rumen pH differs, yet the early lactation cow is often a risk. Dr Greg Penner will dig deeper into this subject.

What are the impacts of liquid addition, forage processing and particle length on cows’ sorting behavior? How much sorting is too much sorting? How short is too short when it comes to processed dry forages?

How AMS (Automatic Milking System) can predict cow health? Dr Devries work has looked at utilizing AMS metrics to predict disease in particular in early lactation cows. How has that worked?

Chronic lameness on the dairy is an issue that can be resolved. Identifying and caring for these cows will have a very positive impact on your dairy.
