The Moos Room™

Brad shares updates from the University of Minnesota Morris dairy herd, including cows heading out to spring pasture, a recent Holstein classification, and highlights from several high-scoring cows. He then revisits University of Minnesota crossbreeding research comparing Holsteins with Viking Red and Montbéliarde crosses. The results show that crossbred cows often had better fertility, lower health treatment costs, improved survival to later lactations, and higher daily profitability, even when milk volume was sometimes lower than Holsteins. Brad also connects these findings to current beef-on-dairy calf research showing health advantages from crossbreeding, especially fewer scours and digestive problems.

In this episode of The Moos Room, Brad discusses spring pasture challenges in western Minnesota, including dry conditions, temperature swings, and slowed grass growth. With summer heat on the horizon, the focus shifts to heat stress in dairy cows and how precision technologies, especially internal bolus sensors, can help farmers identify problems earlier.
Brad shares observations from cows monitored with Smaxtec boluses, including rumination, internal body temperature, and water intake data. He also reviews research from the University of Minnesota herd showing that rumination may start dropping at lower temperature-humidity index levels than traditional industry thresholds suggest. Conventional cows showed rumination declines around a THI of 64, while pasture-based organic cows showed declines closer to 58.
The episode highlights why waiting for milk production losses may be too late when managing heat stress. Instead, rumination, body temperature, water intake, shade, cooling systems, and feeding strategies can all play a role in protecting cow comfort and performance before visible signs of heat stress appear.

Brad takes a closer look at FerAppease, a synthetic analog of the maternal bovine appeasing substance that is gaining attention in both the dairy and beef industries. He explains how the product is designed to reduce stress in cattle during events like breeding, weaning, dehorning, transportation, calving, and dry-off.
The episode highlights recent research in lactating Holstein cows showing that applying FerAppease at the time of artificial insemination increased pregnancy per AI from 47.7% in control cows to 60.2% in treated cows. Brad also walks through the potential economics, estimating a strong return on investment when improved pregnancy rates are valued at the farm level.
Brad then discusses a calf study looking at FerAppease use around disbudding. Treated calves showed signs of reduced stress, including lower cortisol measures, and had improved average daily gain shortly after disbudding. While more research is needed, Brad notes that FerAppease may be a useful non-antibiotic, non-hormonal tool for reducing stress and improving outcomes during key management events.

Virtual fencing is gaining attention in livestock production, and this episode breaks down what dairy producers need to know before trying it. Brad explains how virtual fencing uses GPS-enabled collars or ear tags, audio cues, and electrical cues to manage grazing animals within digital boundaries. He also shares lessons from training heifers with virtual fence collars, including the adjustment period, the importance of using a physical fence during training, and how animals typically learn the system within about a week.
The episode also compares several virtual fencing systems available to U.S. producers, including Vence, Gallagher, Halter, and Nofence. Brad walks through major considerations such as collar weight, cellular versus base station connectivity, battery life, subscription fees, and upfront costs. He also discusses how virtual fencing may compare financially with traditional physical fencing and why more research is needed to understand its fit in dairy grazing systems.
Brad also previews upcoming virtual fencing work at the University of Minnesota West Central Research and Outreach Center, where multiple systems will be tested with dairy cattle to better understand labor needs, cost, practicality, and overall performance in real grazing conditions.

This episode highlights new research on Salmonella Dublin in dairy-beef systems and what it means for calf health and farm management. 
The disease is a major threat to young calves, causing severe illness and high mortality, while often spreading silently through carrier animals and contaminated environments. New PCR testing shows the pathogen is far more common than traditional methods suggest.
Key risk factors include frequent introduction of new calves, mixing animals post-weaning, and human movement (boots, equipment) spreading contamination between areas.
Bottom line: Salmonella Dublin isn’t random—it reflects management. Strong biosecurity, better calf flow, delayed weaning, and improved monitoring are critical to reducing risk.
