Early calf socialization may deliver long-term benefitsCan 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.Questions, comments, scathing rebuttals? -> [email protected] or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

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? -> [email protected] or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

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.Questions, comments, scathing rebuttals? -> [email protected] or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

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.Questions, comments, scathing rebuttals? -> [email protected] or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

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? -> [email protected] or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory
