    Episode 364 - Early calf socialization may deliver long-term benefits - UMN Extension's The Moos Room

    Early calf socialization may deliver long-term benefits Can housing calves together during their first weeks of life affect how they perform as cows? This episode examines University of Florida research comparing individually housed, pair-housed and group-housed calves through their first lactation. Socially housed calves grew faster before weaning, producing up to 16% greater average daily gain than individually housed calves. Although differences in growth and reproductive performance largely disappeared after weaning, important benefits emerged after calving. Pair- and group-housed animals produced approximately 1,700 additional pounds of milk during their first lactation and were substantially less likely to be culled. The findings suggest that early social contact builds behavioral resilience. Calves raised with companions may adjust more easily to the milking parlor, regrouping and competition at the feed bunk—helping them maintain intake, manage stress and remain productive during the demanding transition into the milking herd. The results position social housing as more than a calf-welfare practice; it may also be a long-term investment in productivity and herd retention.

    Episode 363 - What Can AI Tell You About Your Dairy? - UMN Extension's The Moos Room

    Can AI turn mountains of dairy data into practical management insights? This episode explores how tools like ChatGPT can analyze bulk tank records, DHI reports, and milking-parlor data. Using examples from conventional and organic herds, we discuss how AI can reveal production and milk-quality trends, identify cows driving somatic cell count, highlight reproductive concerns, and uncover parlor-efficiency problems. AI cannot replace farmers, advisers, or Extension expertise—and its results should always be verified—but it can save hours of spreadsheet work and help dairy managers focus on the issues that need attention. Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!

    Episode 362 - Age at First Calving: Why 22 to 23 Months Pays - UMN Extension's The Moos Room

    What is the ideal age at first calving for Holstein heifers? Brad examines a Zoetis study of nearly 130,000 cows from 74 dairy herds. Although heifers calving at 26 months produced slightly more projected first-lactation milk, those calving around 23 months produced more cumulative milk through two lactations, remained in the herd longer, and generated greater modeled net income. Replacement risk increased substantially as calving age rose, reaching about 35% for heifers calving at 27 months compared with 17% at 21 months. By 27 months, modeled net income was approximately $650 lower than for the 23-month group because the small milk-production advantage did not offset additional rearing costs and earlier removal from the herd. The findings support targeting 22 to 23 months—but only when heifers are adequately grown. Brad explains why producers should monitor body weight alongside age, evaluate the costly tail of late-calving heifers, and consider cumulative production and survival rather than relying solely on projected 305-day milk.

    Episode 361 - Why Routine Hoof Trimming Pays: Preventing Lameness in Dairy Cows - UMN Extension's The Moos Room

    Lameness can quietly reduce milk production, cow welfare, and dairy farm profitability. In this episode of The Moos Room, we examine how a difficult, wet spring prompted our dairy to make routine hoof trimming a priority for both its grazing and confinement herds. Since 2019, every cow—including lactating and dry cows—has been trimmed twice a year, with hoof problems carefully recorded. The results have been substantial: the percentage of cows with hoof issues declined from 15.6% during the first whole-herd trimming to just 2–3% during the past two spring trimmings. Thin soles and toe ulcers have nearly disappeared, white line disease has declined, and antibiotic use for lameness has fallen. Learn why grazing cows still benefit from routine trimming, how common hoof lesions affect cattle, and why partnering with a hoof trimmer to establish a consistent maintenance schedule can improve cow longevity, employee satisfaction, and farm profitability.

    Episode 360 - Working With the Dairy Cow’s Biological Clock - UMN Extension's The Moos Room

    After a busy week showing dairy cattle at the county fair, Brad explores research on the dairy cow’s 12-month biological clock. Using data from 332 Western U.S. dairy herds, the study examined how region, breed, housing, organic management, and BST use influence seasonal patterns in milk production, components, dry matter intake, and feed efficiency. Despite differences among herds, annual rhythms remained remarkably consistent: milk components peaked in winter, dry matter intake peaked in February, and milk production generally peaked in spring. The findings suggest producers and nutritionists should compare herd performance across seasons—not just from one month to the next—and work with cows’ natural biological rhythms when evaluating production changes and planning diets.  Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!

    Episode 359 - New Calf Health and Fertility Traits: What Dairy Producers Need to Know - UMN Extension's The Moos Room

    This episode previews new U.S. dairy genetic evaluations scheduled for release by the Council on Dairy Cattle Breeding on August 11, 2026. Two new calf-health traits will measure genetic resistance to diarrhea and respiratory disease in Holsteins and Jerseys. Positive predicted transmitting abilities indicate greater resistance. Although these traits have relatively low heritability, they may help producers gradually improve calf health, reduce treatment costs, and avoid the long-term productivity losses associated with early-life illness. Continued, accurate recording of calf health events will be essential for strengthening these evaluations. The episode also explains revisions to several fertility traits, including daughter pregnancy rate, cow conception rate, heifer conception rate, and early first calving. The updated models better account for modern reproductive management, including longer and variable voluntary waiting periods, synchronization programs, sexed and beef semen, and automated monitoring systems. A new trait, first service to conception, measures the number of days between a cow’s first breeding and conception. Unlike daughter pregnancy rate, it is independent of a herd’s voluntary waiting period and may be particularly useful on farms that establish breeding eligibility for individual cows. The host remains skeptical about how dramatically the revised models change historical fertility trends—especially daughter pregnancy rate, which now appears to have improved rather than declined over the past 25 years. Producers are encouraged to examine how the August evaluations affect bulls they currently use, while considering calf-health and fertility traits as additional selection tools rather than replacements for sound management.

    Episode 358 - Footbath Management: What Dairy Farms May Be Missing - UMN Extension's The Moos Room

    After sharing how recent heat stress caused an average milk loss of four pounds per cow in his herd, Brad turns his attention to lameness and footbath management. He examines a study of approximately 250 Canadian dairy farms to explore how footbaths are being used, where management gaps exist, and what the future of hoof-health programs may look like. Most farms sent lactating cows through a footbath one or two times per week, commonly after milking. Copper sulfate was the most widely used product, but Brad discusses its potential to accumulate in soil and affect crop production. He also addresses the health risks associated with formaldehyde and copper sulfate, noting that fewer than half of the surveyed farms reported using personal protective equipment while preparing footbath solutions. Solution management is another important concern. As manure and other organic matter accumulate, footbath products become less effective—often after 150 to 300 cow passages. Keeping a solution too long may mean that cows passing through later receive much less protection. The study also identified major gaps among nonlactating animals: 69% of dry cows and 82% of heifers never passed through a footbath. Because hoof problems in heifers can negatively affect first-lactation milk production and reproduction, farms may need to consider hoof health across the animal’s entire life cycle. Brad concludes by discussing how automated footbaths could improve consistency, shorten solution-retention times, and reduce labor. The key is developing a farm-specific protocol that accounts for cow flow, herd size, chemical safety, solution replacement, and hoof-health challenges across every group of animals.

    Episode 357 - From Calf to Carcass: Early Nutrition for Beef-on-Dairy Success - UMN Extension's The Moos Room

    Beef-on-dairy calves continue to bring strong prices, but producing calves that perform well from birth through harvest requires careful decisions about genetics and nutrition. In this episode, we look at current Minnesota calf markets, the factors influencing beef sire selection and recent research exploring how early feeding programs affect the long-term performance of Angus-Holstein calves. A University of Minnesota study compared conventional 20:20 milk replacer with a higher-energy 24:24 formulation. Calves receiving the 24:24 milk replacer had greater starter intake, faster weight and frame growth, and improved feed efficiency through eight weeks of age. The results suggest that supplying more nutrients early in life may encourage—not suppress—starter consumption. We also discuss an Iowa State University study that followed beef-on-dairy steers from the nursery through harvest. Although pelleted diets produced faster growth shortly after weaning, cattle raised on forage-based total mixed rations performed better later in the feeding period. The low-starch TMR group finished with heavier body and carcass weights, more Prime carcasses and greater carcass value, while the high-starch TMR group experienced substantially more liver abscesses. The research highlights why early growth should not be the only goal. Rumen health, feed costs, finishing performance and carcass quality all matter when developing profitable beef-on-dairy feeding programs.
