The complexities of COOL
The Prairie Star
Country of Origin Labeling (COOL) has risen to the forefront as one of agriculture’s most polarizing topics. Grassroots organizations remain divided on the best approach to product labeling, but it is clear that U.S. beef and pork producers are proud of the product they raise, and they advocate for consumer transparency.
Mouth-Aging Cows Under Five
Dr. Ken McMillan
Teeth can be very helpful in aging cattle. The incisors come in at about the same time in all cattle. Based on a table from the USDA and Mississippi State University Extension, I can tell you the first incisors show full development around 36 months, leveling at 5 to 6 years, with noticeable wear at 7 to 8 years.
Late Summer Establishment of Perennial Forages
Ohio Beef Cattle Letter
We are quickly approaching the second good opportunity of the year for establishing perennial forage stands, which is in the month of August. Most of us were not able to establish forages this spring, and many existing stands were damaged by the winter followed by the heavy rainfall this year.
The Next Generation of Genetic Tools

Why do we use a crossbreeding system? To gain the advantage of heterosis, the cross outperforming the parent average. Retained heterosis is the amount of this advantage that is maintained after multiple generations of mating crossbreed animals (not mating the purebred parents). Dominance, over dominance, and epistasis likely all contribute to heterosis.
The key to sustainable grazing is stock density
For years, I referred to the type of grazing that I do as intensive cell grazing. I am not sure where I first heard the term or why I used it but that’s what I use to call it. I have also called it sustainable grazing or more recently, regenerative grazing. But the truth is that my grazing is still the same no matter what I call it.
Keeping silage ‘pickled’
“I highly recommend inoculants for everyone. It won’t increase the nutrient content of your silage, but your silage will maintain quality rather than losing it,” says Hugo Ramirez of Iowa State University Extension.
How Do Animals Choose What to Eat?
We are so used to considering forage type, nutrition and quantity as we try to improve animal health and increase weight gain, we sometimes overlook how an animal’s interactions with it’s mother and peers affect what and how it eats. Since what a young animal learns has life-long consequences, knowing more about this process can help us be more successful managers.
Avoid Heat Stress When Moving Cattle

Cattle overheat quickly if they have to exert very much on a hot day. Moving cattle is always safer if you start early in the morning. Ray Randall, veterinarian in Bridger, Mont., says that if it gets hot before you get to your destination, you may have to stop and let cattle rest, preferably where they might have some shade. You may be able to give them a break until later in the afternoon, he says.
25 feeder calf mistakes
This fall when calves will be entering the feedlot, the feedlot team including the veterinarian, nutritionist, manager, pen riders and feeders will have the opportunity to all work together to get these calves off to a good start.
Keeping Your Vaccines Viable
Vaccines are a vital part of keeping all livestock healthy. Vaccines help in the prevention of disease, which results in less utilization of antibiotics due to fewer sick animals. Vaccines provide protective immunity approximately 21 days following the initial vaccination in the majority of livestock.
