U of A research could detect Johne’s disease

Currently no reliable test to detect the frequent problem in dairy herds


Johne’s disease is a challenge for the dairy industry. One of the main issues associated with identifying Johne’s is that the calf gets infected at a young age, but symptoms may not show in the animal for years. Johne’s disease is difficult to diagnose and when present, can cause animal mortality, decreased milk production and […] Read more

Digital meat-grading scanner making its way to the processing floor

The device developed at U of A uses near infrared 
and visible light to detect fat and meat colour

Grading is an important step for processors, and the industry has traditionally used human graders to measure qualities such as marbling, as well as fat colour and texture. But processors are now moving towards electronic grading tools and technology. Technologies such as the Computer Vision System’s BeefCam module have achieved up to 64 per cent […] Read more


Research found that feeding corn DDG or fat-supplemented wheat DDG reduced the amount of methane produced in the animal’s rumen.

The environmental pros and cons of feeding dried distillers grains

Cattle fed DDGs produce less methane and more nitrogen, Lethbridge Research Station scientists have found

In beef production, finding a balance between feed costs and environmental health takes continuous navigation. Feed is one of the highest on-farm costs and when the price of barley, corn and wheat rises, producers often turn to using dried distillers grains (DDGs) in their rations. While this ethanol co-product lowers methane production in cattle by […] Read more

Study may allow dairy nutritionists to formulate diets with lower protein content without compromising milk production.

New study aims to improve protein efficiency in dairy cows

Researcher to study how to lower protein content without compromising milk production


In humans, the nutrients you ingest are directly correlated to your performance and overall health. The same applies to animals. Currently, the dairy industry relies on the expertise of dairy cow nutritionists who formulate diets for cows using an established protein model. Unfortunately, this model consistently underpredicts milk protein yield at low protein intake. The […] Read more


ALMA To Invest In Feed Research

The Alberta Livestock and Meat Agency (ALMA) will invest $8 million to tackle the single largest day-to-day issue plaguing livestock producers – the cost and effectiveness of feed for their animals. Funds will be used to: further develop livestock feed; identify better links between feed and animal nutrition; and influence better use of feed grains. […] Read more
