Description
Guests: Dr. Bill Weiss, The Ohio State University; Dr. Jesse Goff, Iowa State UniversityCo-host: Dr. Clay Zimmerman, BalchemToday’s podcast is our January installment of the Journal Club, styled after the traditional journal clubs at universities across the country and around the world. Today we’re a closer look at some of the newest research published in the Journal of Dairy Science.Article 1: https://bit.ly/3zCBdIADr. Jesse Goff, in summarizing a paper from the Netherlands, stated animals on a low phosphorus diet had lower blood phosphorus than the other animals, which isn’t unexpected. But the animal's calcium concentration had improved on a lower phosphorus diet. (5:53)Dr. Bill Weiss emphasized a two to one phosphorus ratio isn’t always correct. The important thing is to meet the NRC requirements for both phosphorus and calcium. (11:38) Dr. Jesse Goff warned that even if you think you are feeding a low phosphorus diet if you are using byproducts - such as soybean meal, canola meal and wet brewers - it can all bring in a lot of phosphorus. You need to be wary of that in the diet. (17:20)Dr. Bill Weiss mentioned you should be in a slightly deficient diet postpartum and not meet the NRC requirements. Dr. Jesse Goff added that a postpartum cow would be pulling phosphorus and calcium out of her bones, needing less in her diet. (29:26)Article 2: https://bit.ly/33hKjyIDr. Jesse Goff and Dr. Bill Weiss summarized the second article, which covered a study with an even lower phosphorus diet than the first article. This study promotes a low phosphorus diet as a way to control hypocalcemia. (36:49)Dr. Bill Weiss mentioned that based on these papers, he thinks the low phosphorus diets in the pre-fresh and in the far-off should not worry as much so you can have some cost-savings in your feed.If you want one of our new Real Science Exchange t-shirts, make sure to screenshot your rating, review, or subscription, and email a picture to anh.marketing@balchem.com.

Scott Sorrell and Dr. Clay Zimmerman are joined by tonight’s guests who span the history of the topic with Dr. Don Palmquist being one of the founding fathers and Dr. Tom Jenkins also providing much of the depth as we dive in on this topic. Dr. Kevin Harvatine is not new to the Real Science Exchange and we are excited to have him back for this discussion. by Real Science Exchange
