Micro-machine helps reduce feedlot waste

/10 Comments/in , /by

Feeding cattle the best diet for growth is a complicated business. Now, new technology is making it not only easier to do but also more efficient. 

Micro-machine technology enables cattle feeders to accurately measure individual additives or supplements that help cattle grow. 

There are three primary constituents in cattle feed – the concentrate, which is typically grain; the roughage, or silage; and supplements, including minerals and vitamins. The makeup of the feed varies with the gender of the animal and how long it has been in the feedlot.

Most Canadian feedlots hire nutritionists to create a balanced feed plan for their livestock.

Once a nutritionist has decided on the optimum supplement blend, it is typically made into a custom pellet. These pellets are then mixed in with the grain and silage. A feedlot might have four or more different pellets formulated for use during different stages of the feedlot growth cycle. 

Simon Cobban, manager of feedlot solutions at United Farmers of Alberta (UFA), said customizing feed for different groups of cattle can be wasteful. “If a feedlot operator wishes to increase the use of any given supplement, he must increase the number of pellets added to the feed. This means increasing all the supplements in that pellet and incurring a great deal of waste.”

How technology is reducing waste and improving accuracy

With micro-machine technology, cattle feeders can measure individual additives or supplements to within 1/100th of a gram. Once measured, these supplements are then sprayed directly onto the grain. It provides a much more accurate and homogenous mix than mixing in a pellet.

“The machines aren’t new, but the high capital cost puts them out of reach for most feedlots,” said Simon. “At UFA, we have a program for cattle feeders where we provide the machine at no cost, as long as they buy our feed, additives and supplements. We install the machine in a custom building, set it up, program it and maintain it. It makes this technology much more accessible.”

Initially, UFA’s micro-technology program was only available for feedlots that feed 10,000 or more head of cattle per year. It is now available to feedlots with 5,000 head, and it will soon be going down to 1,500 head.

“We currently service something like 60 to 65 per cent of the fed cattle in Western Canada,” said Simon. “We have 100 per cent customer retention, and we have quite a few smaller feedlots waiting for when we can reduce that threshold to 1,500.”

How Project Clean Cow is reducing cattle methane emissions by up to half

Cows require an exceptional digestive system to thrive on a diet of grass and other plant materials.

These ruminants have a stomach with four compartments, the first of which is called the rumen. Micro-organisms in the rumen ferment the food and start the digestive process. Each time the cow regurgitates and re-chews the food, this microbial activity breaks down cellulose, fibre and carbohydrates into usable compounds.

An unfortunate byproduct of this digestive process is methane. Cows have been identified as a significant source of greenhouses gases, and the beef industry is committed to minimizing its impact.

Project Clean Cow is a 10-year research project that holds promise of a solution.

Spearheaded by DSM, a global science-based company and a world leader in the field of animal nutrition, the project has developed a feed additive that reduces the methane created through the digestive process of cattle.

“The current Clean Cow project started in 2007, as part of a bigger initiative at DSM called the Climate Change Induced Innovation Project,” said Hugh Welsh, president, North America, at DSM. “Our goal was to develop a feed supplement for ruminants which would reduce methane emissions by at least 30 per cent. This would substantially lower the GHG footprint of cattle, and potentially have a meaningful impact on global climate change-related emissions.”

The project started with input from biologists and chemists at DSM’s research and development unit in Switzerland, as well as experts in ruminant science and animal nutrition. It has since expanded to include an international scientific network.

The result is a feed supplement that consistently reduces the methane produced by ruminants (dairy cows, beef cattle and sheep) by 30 to 50 per cent.

What happens next?

“Our next step is to work hand-in-hand with industry and the scientific community for product launch,” said Hugh.

As a starting point, DSM has commissioned a large-scale field trial to demonstrate the viability of feeding the compound in backgrounding and finishing operations. Field tests by Viresco Solutions, an environmental consulting firm based in Calgary, AB, should be complete by the end of this year. Cattle will be fed with flaked corn, flaked barley and standard barley, in addition to the supplement, to see if there are any effects on animal performance, health or carcass quality.

“Viresco took the lead in applying to Emissions Reduction Alberta to share in the risk of testing at commercial scales”, explained Karen Haugen-Kozyra, President at Viresco.  “We call this ‘on the road to low carbon beef’ – if combined with regenerative ranching, increased feed efficiency and testing new feeding technologies, the entire sustainability story for beef production in Alberta becomes really attractive. We are proud that DSM chose Alberta to test their innovative approach.”

As we learned in a previous blog post, ammonia is another greenhouse gas emitted by cattle. Emissions research, conducted in Lethbridge by Agriculture and Agri-Food Canada, is helping us to understand ammonia’s environmental impact, and find ways to minimize it.
