Vomitoxin: How much is too much in dairy diets?

Posted on August 29, 2014 in Dairy Performance
By Rod Martin This year’s weather conditions have been conducive to the development of vomitoxin in wheat.   The price for this wheat grain can be significantly discounted depending on the contamination level.  Consequently, dairy producers are asking how they can feed wheat grain in their dairy diets without incurring negative production and health effects. Furthermore,

Stop the drain of fresh cow disorders

Posted on October 17, 2013 in Dairy Performance
By Dr. Laurie Winkelman Like a slow leak from a car tire that eventually turns into a flat, subclinical ketosis and milk fever can slowly drain profits from your dairy. Cows with subclinical ketosis or milk fever will appear completely normal, floating under the radar of common detection tools and treatments.  Making real changes to

Get rid of the summer bugs

Posted on September 16, 2013 in Dairy Performance
By Ann Hoskins When it comes to our crops, this summer has been a crazy growing season with lots of ups and downs.  In contrast, it’s been a steady and great growing season for the bugs on our dairy farms and calf operations.  Many farms struggled with flies and pathogenic pests this year. As we

Colostrum for one and all

Posted on February 15, 2013 in Dairy Performance
By Dr. Laurie Winkelman Calves are born into this world without immunity or the ability to fight off pathogens and infections.  Unlike humans, the cow’s placenta does not allow antibodies to transfer from cow to calf.  High quality colostrum is the only way to prepare these newborns for the rest of their lives. The benefits

Limit infections in challenging environments

Posted on November 28, 2012 in Dairy Performance
By Dr. Owen Mickley This season’s temperature swings aren’t easy for calves.  We've been hearing about an increase in navel infections, ear tag infections and joint swelling. Remember, any increase in infection or treatment rate is cause for concern.  These problems may seem minor, but could indicate an opportunity to enhance the current system.  If

Aflatoxin: No room for error in dairy

Posted on September 20, 2012 in Dairy Performance

By Dr. Al Schultz and Rod Martin

Almost every year at harvest, we have a few conversations about common molds and mycotoxins.  However, this year’s weather events have pushed us to look closer at a mycotoxin that isn’t as common in the upper Midwest:  aflatoxin. Aflatoxin is produced by the Aspergillus mold.  It thrives in periods of excessive heat and drought conditions, which is why it’s of particular concern to producers this harvest season.  Spores travel by the wind and infect silks or kernels, usually through insect wounds.

Are you catching and treating dehydration soon enough?

Posted on August 28, 2012 in Dairy Performance
By Ann Hoskins Recognizing and treating dehydration is key to raising healthy calves.  Calves will become dehydrated for many reasons, including summer heat and scours.  If you can catch dehydration early, supplemental fluids can get the calf on the road to a quicker recovery. A calf’s body contains 75 to 80 percent water at birth

Antibiotics in agriculture: What is their place?

Posted on June 8, 2012 in Dairy Performance
By Dr. Al Schultz Since they became a huge part of human medicine in the 1940s, antibiotics have saved millions of lives, but we are getting increasingly worried because they don’t work as well as they used to.  Although the pharmaceutical companies are developing new strategies to address this issue,  the man-versus-bacteria war continues onward.

On-farm biosecurity: Reduce risk

Posted on April 16, 2012 in Dairy Performance
By Ann Hoskins Biosecurity refers to those measures taken to keep diseases out of populations, herds or groups of animals where they do not currently exist or to limit the spread of disease within the herd. The responsibility for farm-level biosecurity belongs to the herd owner and it starts at home with your protocols. A

Keep dry cows cool too

Posted on March 23, 2012 in Dairy Performance
By Dr. Bruno Amaral With an uncommonly warm March, we’re already starting to think about keeping cows cool.  Now is our chance to strategize and get ahead of the heat. We all know the value of heat stress abatement for milking cows as temperatures spike in the summer and milk production drops.  But the value

Get ahead of ketosis

Posted on March 14, 2012 in Dairy Performance
By Dr. Neil Michael Managing fresh cow performance is a challenge.  When ketosis becomes an issue, cows start slowly and you can expect significant losses due to direct treatment costs and lost future income. Contributing factors Much of the variation in how well cows go through transition can be explained by changes in cows, feedstuffs
