DSD 5.5 | Avoid generations of production losses

May 15 2024 32 mins

Florida researchers began a generational study in 2007 that is still years in the making. It all began with the investigation of the impact of heat stress on dry cows to measure changes that might occur to the calf incubating inside the hot dam, like a crock pot. In addition to seeing negative production impacts on mama, the researchers began to measure numerous changes in the dama

DSD 5.4 | Reconsider Choline for lasting returns

Apr 19 2024 36 mins

Choline, a pseudovitamin, is required by all mammals including the dairy cow for many essential functions. Research in supplementing rumen protected choline really took off about twenty years ago, however continues today to best understand how this feed through additive can positively influence profitability. Dr. Usman Arshad joins the conversation for this episode to highlight his

DSD 5.3 | Slight modifications of CIDR Sync - help or hinder?

Mar 15 2024 27 mins

DSD 5.3 | Slight modifications of CIDR Sync - help or hinder? In this time of heifer inventory shortage – getting heifers pregnant (in a timely fashion) is even more important than ever. Contract heifer growers in California sought the help of Dr. Fabio Lima and his team at UC Davis to best understand the use of a 6-day CIDR sync with variable rates of GnRH could increase pregnan

DSD 5.2 | Stop fresh cow subclinical mastitis in its tracks without withhold

Feb 15 2024 24 mins

Getting the fresh cow off to a strong start has ripple effects for her entire lactation. Subclinical mastitis rarely gets treated due to an unawareness or a lack of interest in pulling her from the tank. Nisin is a naturally occurring antimicrobial that’s been used widely as a food preservative. Dr. Zelmar Rodriguez and his team from Michigan State University looked at using this

DSD 5.1 | Energy saved is energy earned

Jan 15 2024 19 mins

Efficient production is the name of the game, and the key to an efficient cow is her rumen microbiome. The highlighted research this month focuses in on the intersection of Genome of the host cow, Microbiome within the rumen and the Intersection of the two. To best understand the rumen efficiency story we talk this month with Dr. Guillermo Martinez Boggio from University of Wiscons

DSD 4.12 | Mature mamas sail through transition with beef cross calves

Dec 15 2023 25 mins

Beef on dairy is here to stay. These cross animals generate a revenue stream for dairies as it lubricates the parallel industry of beef production. Much research is being poured into this topic to ensure producers can make wise breeding choices going forward. This month we talk with Bailey Basiel from Penn State University, about their recently released paper titled: The impact of

DSD 4.11 | Reproduction Revolution

Nov 15 2023 37 mins

Over the past 30 years the reproduction status of dairy has improved substantially, largely due to research around reproduction synchronization. This month we talk to Dr. Paul Fricke and Megan Lauber from the University of Wisconsin, about their recently released paper titled: Effect of postpartum body condition score change on the pregnancy outcomes of lactating Jersey cows insemi

DSD 4.10 | Prevent Early Embryonic Losses

Oct 15 2023 30 mins

Pregnancy is the key to profitability, ensuring your herd remains in the most profitable phase of production. However, these early embryos are delicate and often are not carried out through the entire 283 days of gestation. This month we talk with Dr. Stephen LaBlanc, from the University of Guelph about quantifying the frequency of early pregnancy loss in healthy animal and his tea

DSD 4.9 | Is your starch locked up by Zein proteins?

Sep 18 2023 28 mins

Corn silage is such piece in your ration. Much work has been done by corn breeders to create the most ideal plant with high yields, digestible forage AND starch to support lactation. This month we talk with Dr. José Varela and feature a foundational silage project he and his team worked on at the University of Wisconsin to better understand specifically how zein proteins around co

DSD 4.8 | How does grass-based milk impact human nutrition?

Aug 15 2023 37 mins

Research in Ireland is focused around better understanding the intersection of management and cattle nutrition on the quality of the milk produced within a system. This month we talk specifically about three different feeding strategies – TMR, PMR or grass based investigated for an entire lactation. The vast majority of Irish dairymen attempt to maximize use of grass as the prima
