DSD 6.10 | Summary of Social Housing for Calves

Dairy Science Digest ·

2025/10/16

Individual housing for pre-weaned calves has long been gold standard, since it was first introduced in the 40s. However, interest has emerged around paired and group housing for this phase of production. Intermittent research on this topic has been published over the past 25 years but has never been compiled, until now. Dr. Katarina Buckova from IA State University, and her team combed through research databases and compiled the results of several projects on paired housing, compared to

DSD 6.9 | Surplus calves are a perishable commodityThis robust beef market is having a direct impact on the bottom line of dairy calf buyers and possesses the ability to radically impact dairymen’s bottom line long term through low all milk prices. This month we talk to researcher Dr. Sam Locke from The Ohio State University about a survey launched to help better understand the workings of the current calf buyers, jockeys and marketers. All sectors of this parallel and complementary production

DSD 6.8 | That is where you should put your moneyFor years researchers have sought out to better understand control mechanisms for a successful transition into lactation from the dry period. We’ve learned changing body condition score during the dry period is not acceptable, but what if it changes during late lactation? How does this impact energy partitioning for the next lactation? Well managed high producing cows with high fertility might find themselves bred back in less than the “textbook

It’s always exciting to watch a group of replacement heifers develop and anticipate their performance in the milking string as the top genetics of your herd. There is just about nothing more devastating than freshening them in to find mastitis or even worse, a blind quarter. When a first calf heifer calves in with a high somatic cell count she is more likely to maintain the high count, and more likely to be culled.Heifer mastitis, or intramammary infection (IMI), is a common affliction yet we know

DSD 6.6 | How much variability is allowable? Timing of insemination is still one of the most common question Dr. Paul Fricke, Extension faculty for the University of Wisconsin, gets from farmers. This month he and coauthors Vanda Santos and Paulo Carvalho discuss the ideal timing of insemination when using popular artificial insemination protocols and when producers use estrus detection devices. Additionally, how does this change if you choose to use sexed semen or a straw of beef? Listen in to

2025/05/16

For decades, ethanol production has generated affordable biproducts to feed. A new distilling method has generated a product with ~50% protein. Dr. Billy Brooks, assistant professor of dairy science at Kansas State, wanted to understand how this feed would compare to soybean meal in a starter grain.To test this he developed rations substituting soybean meal 1:1. Graduate student Rachel Skinner measured intake, growth, effiency and metabolic and digestive parameters to best understand if this

DSD 6.4 | A dynamic rumen, preweaning

Dairy Science Digest ·

2025/04/17

Most dairy farms are trying to push the envelope from the conventional 4L of milk replacer per day to a higher volume to support lean structural growth of replacement heifers. Concerns of ruminal leakage resulting in fermentation has been cited as a concern, but is that based on an incomplete picture? We know microbial protein offers a nearly perfect alignment of amino acid requirements for the bovine, however nutrition programs have discounted milk replacer to exclusively providing rumen

DSD 6.3 | Big Picture Management Decisions Matter Timeless dairy management decisions, such as voluntary waiting period & days dry, have recently been the topic of interest across the globe. Scrutiny to illuminate the ideal to maximize productive life has left the industry questioning convention. Michael Overton, DVM at Zoetis worked with co-author Steve Eicker to tease out the answers to these questions from a a massive dataset of 109,000 cows across 60 herds nationwide. This retrospective,

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

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,

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
