It may not seem like it, but now is the time to be thinking about heat mitigation and ventilation strategies.

Take this expert insight from Dr. Nigel Cook on the latest industry data and what it could mean for your operation's heat stress situation: https://t.co/zwhqkQfRdA

[Michael J. Wolf DVM @DVMWolf]

Work with professional ventilation providers that understand the adaption of these targets for your geographical location, climate & barn designs.

“Data shows as temperature increases we lose about three hours per day of resting time." Read about how you can improve lying time with increased air speeds at https://t.co/Jxa3aOssK4.

Maybe you should have sold some fans in Ukrainian or at least point some to the eastern side that might cool the situation there.

[Huw Jones @huwjonesVES]

Reached the Ukraine border today discussing ventilation strategies with some great producers! Got myself point in the direction of home now ✈️

[Michael J. Wolf DVM @DVMWolf]

@CrummySean @tinturholsteins I believe these measurements are primarily used on virgin beef heifers. Attached is an extension paper regarding its use from Nebraska https://t.co/P2iNpCXJFE

@huwjonesVES Holidaying again Huw? You & Boris?

[Michael J. Wolf DVM @DVMWolf]

@UMNmoosroom @DairyKNOW @UMNExt @em_krekelberg That’s what happens when you have “Popeye” forearms & not conditioned for the abuse. Speaking from 42 years of practice, it will eventually take its toll on other joints on that arm. I think the cows don’t miss me being routinely in the palpitation rotation much now either. 😂

Great family incorporating Ag Tourism to educate the public on the production of high quality milk in a modern high welfare robotic dairy facility. Incorporating @VES_Artex ventilation system

@StuDairyVet @HefinR @mark_sc0tt @CargillAnimalUK Overall each dairy based on location, orientation, surroundings natural & man made elements, legacy design, stocking density, production level, animal breed etc play into ventilation needs. Don’t forget importance of ventilation needs during the cool/cold months. Fresh air is 🤴

[Michael J. Wolf DVM @DVMWolf]

@HefinR @StuDairyVet @mark_sc0tt @CargillAnimalUK Estrus activity begins to decline in these ranges & transient CBT rise in collecting yard can result in lower PR seen in the weeks ahead. Cooling collecting yards with fans & soakers whether housed or pasture system very worthwhile investment. Each 0.5°C rise in CBT, CR drops 7%

[Michael J. Wolf DVM @DVMWolf]

@HefinR @StuDairyVet @mark_sc0tt @CargillAnimalUK The temps,THI reported are just at the threshold of detecting effects on rumination & milk yield. Recovery each night with environmental temps around 16°C allows basal CBT to return <39°C. Cows can remain resilient if daily recovery is achieved.

[Michael J. Wolf DVM @DVMWolf]

@conorcasey1 @tomsmithfarmer In the meantime angle the fans at 18-20° down towards the cows. If the bottom is above 8’ the & meets local safety code, remove the grills unless they are part of the structural integrity of the fan. Regular Cleaning of grills & blades has a huge impact on any fan’s performance

[Michael J. Wolf DVM @DVMWolf]

Gas detection may be helpful, but may be too late if gas is overwhelming. Many slatted barns reduce toxic gas risk with an aggressive ventilation strategy routinely and especially during pit emptying.

[Hefin Richards @HefinR]

Another tragedy - I hate slatted sheds - far too many lives lost like this, any farm with a slatted tank should have gas detector at hand

I guess if folks are all in favor of defunding police, an impromptu posse of responsible bovine citizenry may be a solution.

Timely topic from Dr Zach Janssen @cowvett

[Mark Scott @mark_sc0tt]

Do calves need a heat stress chart? https://t.co/nQAkFOnsMK

[Michael J. Wolf DVM @DVMWolf]

Nice job Huw. Incorporating fresh air injection with ECV72 for distribution and cooling velocity plus fly deterrent air speed during warmer days. Also extends rebedding schedule by drying bedding. @VES_Artex

Latest retro fit in Hungary 🐄

[Michael J. Wolf DVM @DVMWolf]

Repro will drop from elevated THI sooner that milk drop will indicate heat stress. Problem is often the damage is not realized until several weeks after the THI events. Proactive vs reactive cooling strategies @VES_Artex

[Cargill Animal Nutrition - UK @CargillAnimalUK]

During the summer period 2020 our shed data loggers showed that 98% of the days saw a THI causing reduced oestrus activity, 25% of the days saw a THI causing reduced conception rates and 8% of the days saw a THI causing milk protein to reduce.

Thanks for the 👍 @tinturholsteins Always learning with high welfare dairies around the world to create the optimal animal centered environments cows require for health, productivity, profitability. I’m blessed by the challenges & dairy owners I’ve had the privilege to work with

[Barkley Dairy Solutions Ltd. 🐄🐄 @Brklydairysol]

@dairy_hannah University of Wisconsin have some nice designs and info
@DVMWolf is a world of knowledge on ventilation
