Cow Environmental Stress
A visit on July 4th to a dairy farm that employs aggressive fan cooling for their dairy cows (Key Considerations – Fan Cooling Cows) reminded me how much cows really need direct evaporative cooling (sprinklers) to mitigate heat stress when summertime heat waves hit. Cows lying in their sand beds were aggressively panting and drooling saliva with every breath. While sprinklers cannot be located to cool cows when resting in stalls, they can do a great job at the feed bunk, holding areas, and return alleys.
Keys to successful sprinkler systems include:
- ample water supply, up to 50 gallons per cow per day
- adequately sized pipe to deliver required water to sprinkler manifold pipes
- low pressure within manifold pipes – about 20 psi
- nozzles located so that cows’ backs and upper flanks are soaked to the skin in about two minutes of water application
- fans located over feedbunk to remove cow-evaporated moisture from immediately around the hair surface for the balance of a 10 to 15 minute wetting cycle
- an appropriate system controller with proper settings
Details on sprinkler cooling systems can be found on pages seven through nine of Application and Management of Dairy Cattle Heat Stress Relief Systems.

CCE Forage Exchange Site
Given the severe drought across much of NYS this year and the potential need for additional forage on dairy farms across the state, the online CCE Forage Exchange has been restarted. Producers or growers with surplus forage or corn may use this site for free to list what they have for sale. Interested buyers may use this site to find what they need and make arrangements directly with sellers. The site URL is below along with a “how to post an ad video.”

- New York Dairy Farmers: Pride & Progress is a series of six different videos on YouTube featuring dairy farms in our area that were willing to share their introduction into dairy farming as well as their passion working on the land. Each is only a few minutes long and is very positive toward Dairy.
- Towards a Successful Future for Farm Families recording is good management tune up for folks who are interested in making improvement in their farm business.
- New Tool: Estimate Total Yield Profit Loss From Weeds an excellent tool that helps you become aware of the damages weeds can cause to your revenue in the existing year.
- Pro-Dairy Thursday Webinars The beginning of each week, topics to be discussed are announced. On Thursdays, webinars take place and run for an hour after lunch between 1 p.m. and 2 p.m. I was drawn to a topic on valuing agricultural land based upon the over the road distance from the major operation. There is also a Library of previous topics that one can view if you’ve missed any or are unable to join the webinar.
A 2015 list of stored grain insecticides registered for use in NY. Thanks to Mike Helms for generating/updating this list! Hard to believe it’s been two years since we’ve looked at it. There were a few minor changes from 2013 – namely a name change to a couple of products. A few new ones were added based on some products discovered when checking the old list and running a very quick NPIC database scan. The list is not inclusive but should provide a good cross-section.
