- Minneapolis MN, US
Stephen G. Campano - Glen Allen VA, US
Gary Carl Larson - Shoreview MN, US

International Classification:

A01N 37/42

Abstract:

Embodiments herein relate to animal feed preservatives including byproducts containing levulinic acid and methods of making and using the same. In an embodiment, a method of making an animal feed preservative is included. The method can include obtaining an acidic byproduct of a manufacturing process. The acidic byproduct can include at least about 1% by weight levulinic acid or a salt thereof. The method can further include mixing the acidic byproduct with a base to form the animal feed preservative. The animal feed preservative can include at least about 5 wt. % of the acid byproduct. In various embodiments, a method of reducing the amount of mycotoxins formed in an animal feed product during storage is included. In various embodiments, an animal feed preservative or supplement is included. Other embodiments are also included herein.

Abstract:

A method for printing a three-dimensional part with an additive manufacturing system, the method including printing layers of the three-dimensional part and of a support structure for the three-dimensional part from multiple print heads or deposition lines, and switching the print heads or deposition line between stand-by modes and operating modes in-between the printing of the layers of the three-dimensional part and the support structure. The method also includes performing a purge operation for each print head or deposition line switched to the operating mode, where the purge operation includes printing a layer of at least one purge tower from the print head or deposition line switched to the operating mode.
