Colostrum, the life-giving liquid-gold first milk that builds the calves’ immune function. The dairy industry has made amazing strides on colostrum management, however we’ll always have a small number of cows that come in with enough colostrum, just moderate quality. What can we do to enhance the colostrum to ensure the calf’s success? Dr. Sandra Godden, from the University of MN Vet Med, and her team of researchers sought to better understand what would happen if they directly added dry colostrum replacer to the moderate quality colostrum? Is it better to reconstitute and feed separately? Listen in to learn ways to improve your colostrum program and how to enhance that moderate quality colostrum.

DSD 6.1 | Management to create the invisible cow If you pause and think about a list of cows – chances are the list that pops into mind is a group of troublemakers that didn’t breed back or need another round of treatment or are on this week’s cull list. What if you could create a herd of unmemorable cows – ones who just do their job; make milk, breed back, no mastitis – the "Invisible Cow". Dr. Krogstad’s research program’s goal is to create more invisible cows; ones you only see at calving, breeding and dry off. This month he shares with us a dataset analyzed for associations of hyperketonemia (HYK) with body condition, milk production, pregnancy loss, mastitis and ultimately culling. It turns out that the timing of lipolysis determines if it is healthy or harmful and ultimately has a big impact on her success through transition. It all boils down to are the free fatty acids being mobilized to fuel early lactation being completely oxidized or partially oxidized? Listen in to learn more about our featured article: Associations of Body Condition Score, Body Condition Score Change, and Hyperketonemia with Mastitis, Reproduction, and Milk Production Topics of discussion 1:40 Introduction of Kirby Krogstad 2:39 Definition of hyperketonemia (HYK) 4:22 Frequency of HYK 5:16 Milk yield decrease due to hyperketonemia 7:36 Figure 3: Prepartum BCS by lactation 9:39 Ideal range of prepartum BCS 10:17 Impact of BCS loss on pregnancy loss 12:04 What’s the biology behind the pregnancy losses? 13:58 How does hyperketonemia impact odds risk mastitis? 14:44 Cellular rationale behind increased mastitis risk 16:36 Figure 5: Health status impact on milk yield 18:16 “Healthy” Lipolysis 18:58 Were cows with high BHB treated? 19:43 Week one vs week two – Timing of Lipolysis 20:40 Healthy Lipolysis generates the invisible cow 22:11 Can you suppress inflammation to improve transition? 23:08 Lipolysis in week one 25:24 Culling association to hyperketonemia 26:15 BCS association to culling 27:27 Impact of stable BCS 28:14 Prevalence and goals for HYK 29:07 Rumen protected niacin for the transition herd 31:01 Transition BCS recommendations 32:05 Take away for boots on the ground dairy producers Featured Article: Associations of Body Condition Score, Body Condition Score Change, and Hyperketonemia with Mastitis, Reproduction, and Milk Production #2xAg2030; #journalofdairyscience; #openaccess; #MODAIRY; #InvisibleCow; #BCS; #ketosis; #pregnancyloss; #Maturecow; #transitiondairy; #HYK; #lipolysis; #dairysciencedigest; #ReaganBluel;…

42:04

Reproductive physiologists are always trying to improve conception rates for the dairy herd. Double ovsync is one of the best tools in our toolbox to submit cows to first insemination. However, as estrus detection technology becomes more affordable and we learn more about physiology, perhaps combining the expression of estrus at insemination may improve fertility through optimizing ovulation timing. Dr. Julio Giordano and Ana Laplacette worked with their Cornell reproduction team to investigate this theory on over 4600 cows in 2 commercial herds. “We are trying to take advantage of the power of sync of ovulation and the power of estrus” Giordano explains. “To get the best of both, synergize the two.” The only change to the well-known Double ovsync protocol includes a delay in the final administration of GnRh before breeding. The goal, allowing the cows more time to show estrus. Take a moment to listen in to better understand the physiology of this synchronization program and how to improve your herd’s reproductive management.

DSD 5.10 | Rumen friendly fatty acids in High Oleic Beans Soybeans and dairy cows have walked hand for decades. These oil beans are known specifically for the amino acid sequence in their high-quality protein and energy to support lactation. Recent developments in plant breeding has shifted the fat profile of the bean contain a higher amount of Oleic fat, which is easier for the rumen to digest, in certain varieties. Substituting linoleic acid for higher concentrations of oleic allows nutritionists to increase the inclusion rate in the diet and therefore support the herd during times of high production. This month we feature an article from Dr. Adam Lock and his team at Michigan State University as highlighting research generated from on-farm questions. Ensuring producers know how much to feed, and how to feed high oleic soybeans to the herd was the objective of a series of research projects in the pipeline of publications due to come from MSU in the coming months and years.

When your bulk tank volume takes a plunge through the last bout of heat, do you ever wonder exactly WHY? What is it in the udder that changes to cause the decline? Why do we also commonly see elevated SCC in our tanks too? To best understand the why, the Virgina Tech dairy team collected tissue samples from the mammary gland of cows in controlled environmental chambers. This month we invite Dr. Ben Corl to explain the cellular changes observed in the alveoli, epithelial and even immune cells of the mammary gland of cows undergoing a controlled heat stress challenge. Additionally, he’ll describe the changes in gene expression in those same tissue samples that controls protein production and mammary health.

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 damaged calf coming out of the heat stressed dry cow. This month’s edition, we’ll be interviewing Dr. Jimena Laporta , of the University of Wisconsin, to better understand the physiological changes of the calf that results in lost production for her entire life . She and her team measured changes in mammary and adrenal gland development. Several separate papers have been peer reviewed over the 17 years of research.

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 Wisconsin, about his recently released paper titled: Host and rumen microbiome contributions to feed efficiency traits in Holstein cows . Here they studied how the rumen and the host interact and if that interaction can become a selection trait in the future. Much of the discussion today is focused around Carbon chasing. Just like “a penny saved is a penny earned,” whenever carbon is conserved by the rumen microorganism, energy is conserved. This carbon unit of energy can then be used to produce more milk when conserved. Listen in to learn more about the interconnected web between the cow and her microbiome.

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 beef sire breed on dystocia, still birth, gestation length, health, and lactation performance of cows that carry beef x dairy calves. While we all know how desirable this cross calf is to the market, there’s very little knowledge about how these breedings impact the dam, until now. Listen in to how this research team sought to determine if there were any negative production implications to your dairy herd when you breed to beef. Topics of discussion 1:27 Introduction of Bailey Basiel 2:26 Objectives of the trial – Impact carrying beef on dairy calf might have on the dairy cow 3:24 Board invited review of Beef on Dairy 4:05 Historical background of Beef on Dairy 5:15 Calf fed Holstein model 7:54 Data set description 10:05 Beef semen description 10:47 Gestation length 13:00 Management changes based on gestation length 14:00 Wagyu crosses 15:00 Long gestation, does that equal stillbirth? 17:10 Health impacts for dams bred to beef semen 20:35 Next research / records needed for genetic assessment - 23:23 What do you want dairy producers to know from your research Featured article: The impact of beef sire breed on dystocia, still birth, gestation length, health, and lactation performance of cows that carry beef x dairy calves.
