The Nutritionist

Rick gave an excellent presentation about the animal behavior factors that affect the productivity of dairy cattle. He discussed the impact bunk space, parity, and dominant cow proximity have on dry matter intake. It was a great talk-Rick is always an engaging presenter. Because Rick is such a Johnny Cash fan, we changed our usual pre-webinar music from classical to classic Johnny Cash–it was kind of fun.

Our WebEx platform suffered an unexpected failure of the recording feature. It may have been operator error but Dr. Shaver was kind enough to re-record the presentation so that we could have it archived. Unfortunately the polls and the Q&A session were lost.

Dr Silva Del Rio’s talk was focused on feeding accuracy: What we need to do to ensure that our fed diets are as close to the formulated diets as possible. She has done much research on the multitude of ways that feeding system can breakdown, usually as a result of human errors at the mixing wagon. Her well presented talk is a natural follow-up to Dr Undersander’s discussion on the factors in making good corn silage. Dr. Silva Del Rio would also like listeners with any questions to feel welcome to email her [email protected]

Dr Undersander discussed seed selection, harvest timing, and treatment of corn silage as it relates to digestibility and production.

The series is intended to give the presenters the chance to deliver messages devoid of company bias. Tom, who many know from his position as CEO of AMTS, continues to work on and contribute to the CNCPS model development. He does this from a purely scientific perspective; his webinar gave him the opportunity work in that realm.

We experienced our first Spring lightening storm just prior to the webinar; this resulted in some connectivity issues that caused our audio to be a little choppy. As you listen, you may notice some dropped words, we hope it will not be too distracting.

Dr Mike DeGroot gave an excellent and very practical webinar as the second presenter in The Nutritionist Series. Mariann Fessenden and Tom Tylutki coordinated the English language WebEx presentation from Groton NY. Almost 2800 miles away in Visalia, California, Dr. DeGroot gave a tremendous presentation on the use of By-Products. The presentation was broadcast worldwide in English, Spanish, and Portuguese. Paula Turiello in Argentina facilitated translating the Adobe webinar for over 100 registrants. Marcelo Hentz Ramos, director of 3Rlab in Brazil coordinated the Portuguese Language GoToWebinar for which he had over 200 attendees sign up. The English language had over 75 people pre-registered. One of the great features of these events are the Question and Answer session at the end. We are uniquely able to field questions from participants in all three languages.

The first in a series of informational webinars in The Nutritionist was delivered and recorded from our Groton Office. Mike VanAmburgh, Tom Tylutki, and Mariann Fessenden were joined by Marcelo Hentz Ramos in Brazil and Paula Turiello in Argentina and over 250 attendees world wide. Mike delivered a marathon presentation on the updates to the CNCPS platform. In addition to an excellent presentation, the question and answer period was terrifically informative. Settle in, it is a long talk–well worth it.

This podcast is an overview of the history of the Cornell Net Carbohydrate and Protein System from it’s inception in 1978 up until version 6.1 released in 2010. We were greatly assisted by information derived from an earlier blog posting by Danny Fox and a wonderful paper called The Sniffen Affect by Chalupa and Boston. Information about the evolution of the model in the last decade was pulled from various proceedings papers coming out of Mike VanAmburgh’s research group. We hope you enjoy this little bit of history in anticipation of the upcoming release of the CNCPS version 6.5 and our subsequent release of AMTS.Cattle.Pro, version 4.0.
