An Aggie, Aussies, and Sampling…

Howdy!

We’ve been busy at the yard the past week. All of this rain we’ve been having has made for some muddy conditions! Everyone is working as hard as they can to clean out pens before we receive new cattle this upcoming week.

In addition, we had a tour group of Australians join us Friday afternoon to learn more about the feedlot industry in the United States. They were especially baffled by how close we are to ground water here in Cozad, being that the feedyard is right over the Ogallala Aquifer makes it just a short distance, about 10’, to ground water as opposed to their 500’ deep wells in Australia. Overall I think they really enjoyed their experience at Will Feed, and we certainly enjoyed their company!

Another very important task we accomplished this week was sampling feed stuffs for monthly nutritional analysis. Being that I am studying ruminant nutrition, it only seems fitting to share a bit about this critical aspect of the feedyard.

RationEVWe feed all of the cattle rations that are formulated with the help of the nutritionist. A ration can be thought of as a casserole. There are a variety of ingredients that all serve a different nutritional purpose whether it’s cracked corn for energy or roughage for fiber content, the ratio of ingredients within the “casseroles” are carefully calculated to meet the specific needs of the cattle at certain stages of growth.

If we do not know the right nutritional contents of our ingredients, our rations will be off and the cattle may not be able to reach their full potential and it could even cause health problems such as bloating. By sampling each individual ingredient, we can check the composition and ensure we are keeping the cattle happy and healthy with properly formulated rations.

All of the ingredients for a ration are loaded into the feed truck and the back of the truck acts like a giant mixing bowl. There is a combination of paddles and augers that mix the ration after all ingredients have been added. In theory this should create a perfectly homogeneous mixture.

To ensure this is the case, we also must sample the rations once they are mixed and delivered to the bunk. This ensures the feed truck is working properly, thoroughly combining all of the ingredients, and there is consistency amongst what is being fed.

DeliveringFeedEV
One load of feed in the truck may be dispersed throughout multiple pens, it is key that what is delivered to the first bunk is the exact same as what is delivered to the last. Therefore, we collect samples along the bunk line from the first and last bunk the load was delivered to.

RationSamplingEVOnce all the samples are collected, both individual ingredients and mixed rations, they are brought to Ward Laboratories in Kearney, NE for testing. The feed results are reported back a few days later and analyzed by the nutritionist, that way rations/mixing procedures can be adjusted accordingly if necessary.

The nutritionist especially uses the calcium content as an indicator of how well the ration was mixed. It is important the mix is homogenous for a variety of reasons but especially so the supplement pellet is distributed to all of the cattle at the right amount being that it includes a variety of ingredients vital to food safety.

When we dropped off the samples, Dr. Ward was nice enough to show us around the lab. They do a variety of testing there including, soil, water, and feedstuffs.

Did you know people will send in homemade craft beers to be tested for mineral content to best be able to match/adjust their unique flavor profiles?

It was definitely a week full of learning experiences! I look forward to my last few days here in Cozad. We have a busy schedule ahead with lots of incoming cattle to receive, process, and acclimate!
