Animal Manure Management

Recycling local manure nutrients before purchasing fertilizer is key to protecting the environment. Manure can be an economic “Win”, due to its fertility value, and a soil quality “Win”, due to its organic matter.  But it can also be a community risk, due to odors and pathogens. Our live educational programs, online courses, and resources provide science-based information on economically viable, environmentally sound manure handling systems that also comply with all regulations.

Not All Manure is Created Equal

Chicken, Beef, Swine and Dairy are all manures. All are valuable, but are they equal? Absolutely not. I could rank them by smell, another by their nutrient content, another by proximity to them, and yet someone else could separate them for their ability to influence soil health charateristics. This article will discuss a little about the different kinds of manure and explain why not all of this valuable product is created equal.

With silage harvest coming up quickly, manure application will soon follow.

Meeting Water Needs of Cattle in the Feedlot

 Figure 1. Crowding of cattle around waterers on hot days is common in feedlots and adds to the challenge of ensuring water access to all animals (Courtesy: Dr. Rick Stowell, University of Nebraska, Lincoln).
Various factors affect water intake; but temperature, humidity and feed intake are the main drivers. Additionally, the first heat events of the season (late May and early June) are the most stressful on cattle: cattle are generally reaching finishing weight and condition, they are not acclimated to heat, and they have not shed their winter coat. This transition also catches managers and staff off guard as they are focused on late-winter yard management.
