Sustainability Requires Definition, Standards, Measurements

Originally printed in The Land - April 19, 2018 https://z.umn.edu/CortusTheLand


My name is Erin Cortus and I am a new faculty member in the Bioproducts and Biosystems Engineering Department at the University of Minnesota. My role is to provide engineering expertise in the area of sustainable animal agriculture systems. Through Extension and research, I work with producers and community members to understand and continually improve the environments in which we raise livestock.

What is a sustainable animal agriculture system? The answer depends on many things, and that is what makes my job both exciting and challenging.

At the heart of most agriculture sustainability definitions you find the following question: What are the current social, economic and environmental considerations that allow a system to continue to produce food, fuel and fiber for future generations? This goal seems simple enough, but we also have to consider the following. Every farm, company and industry has unique …

New Online Tool Helps Farmers, Applicators Time Manure Applications with Weather

The Minnesota Department of Agriculture (MDA) has teamed up with the National Weather Service to design a tool that helps farmers and commercial applicators determine the best time to apply manure.

The Runoff Risk Advisory Forecast tool uses past and predicted National Weather Service weather data like precipitation, temperature and snow melt. It predicts the likelihood that applied manure will run off fields in daily, next day and 72 hour increments. Farmers and commercial applicators use an interactive map to locate their field and find the forecasted risk. Users can also sign up for email or text messages for their county that alert them to a severe runoff risk for that day.

When someone goes to the interactive map, the runoff risk is displayed in one of four categories: no runoff expected, low, moderate and severe. When the risk is moderate or severe, it is recommended that the applicator evaluate the situation to determine if there are other locations or later dates when the manur…

Livestock Owners Encouraged to Review Regulations Before Moving Animals This Spring

Message from MN Board of Animal Health


Spring and summer exhibitions, like county fairs, are right around the corner. The Minnesota Board of Animal Health reminds livestock owners to review animal health and movement regulations before hitting the road. Moving livestock can be a burdensome process, which can go much smoother when everyone prepares ahead of time. Regulations at exhibitions, for official identification and health documentation (for animals moving between states), are in place to protect the health of the animals and the livelihood of livestock businesses and enthusiasts.

Before you even begin getting ready to move your animal, make sure it's healthy by scheduling an appointment with your veterinarian. If you're moving your animal interstate, or out of Minnesota, you must have your veterinarian examine the animal and write you a Certificate of Veterinary Inspection. This document helps animal health officials track animal movements and trace disease if those anim…

2018 Updates to Common Swine Industry Audit

Every year the Industry Audit Task Force reviews feedback from producers, packers, auditors and customers regarding the Common Swine Industry Audit to help clarify and revise portions of the audit.
There are no new questions or required records. The majority of the changes for 2018 are clarifications to the standard.

Details of the 2018 updates are as follows:

Animal Observations
Excessive prod use was added as a willful act of abuse for consistency with the transport/load-out sectionBoar harnesses were added to the animal handling sectionClarification on what to evaluate was added to the deep wounds and scratches benchmarking sectionsInstructions for auditing thermal comfort/air temperatures and air quality were added

Understanding Tail-Biting in Pigs through Social Network

By: Yuzhi Li, Haifeng Zhang, Lee Johnston, and Wayne Martin - University of Minnesota
Reprinted as posted on Swine Minnesota blog.

This study focused on the effect of social network on tail-biting in pigs. The full-text of the article is available in open-access on the website of the journal Animals.

We know that pigs are social animals and that they naturally form social structures to maintain a cohesive group. However, we have little understanding of how those group dynamics affect deleterious behavior like tail-biting. To answer the question of the association between social structure and incidence of tail-biting in pigs, the researchers created 18 groups of 8 pigs. 6 groups were Littermates: all the 8 pigs were born from and nursed by the same sow.6 groups were Half-group of littermates: 4 pigs were born from the same sow whereas the 4 others came from the litter of another sow.6 groups were Non-littermates: all 8 pigs were born from a different sow.
