The present invention relates to xylanase variants, polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; compositions comprising the xylanase variants and methods of using the variants.

The subject invention provides compositions and methods for feeding livestock animals and reducing greenhouse gas emissions from livestock animals. The compositions comprise one or more beneficial microorganisms and/or growth by-products thereof, as well as one or more nutritive mineral components. In certain embodiments, the composition is formulated as a compressed mineral assembly, such as a salt lick or mineral lick, which, when made available to a livestock animal, can be ingested by the livestock animal.

Novel products formulated for use as nutritional supplements are designed to enhance oral health and immune function in mammals. An exemplary composition can be customized by adding nutritional or therapeutic ingredients according to a health condition or medical requirement. Oral formulations are described which can be used as dietary supplements on a daily basis to effectively prevent plaque formation in the oral cavity in addition to providing immune protection mediated by enhancing saliva secretions.

The present invention relates to a mineral dietary supplement for ruminants comprising an organic-inorganic complex based on urea, and various clays for improving the animal's performance by the effect of delaying the release of urea in the rumen. The clays comprise at least one fibrous clay and a nonfibrous clay, preferably attapulgite and montmorillonite.

Mycotoxin-deactivating aptamers, especially DNA aptamers, bind to mycotoxins in feed and feed ingredients resulting in the reduction or elimination of toxic and carcinogenic effects of mycotoxins. The invention also discloses a composition comprising a mycotoxin-deactivating aptamer, a binding agent, a biotransforming agent and an antioxidant for detoxifying mycotoxins in feeds. In addition, the invention teaches the methods of preparing the mycotoxin-deactivating aptamer-based composition and also the methods of using it as a feed additive. Furthermore, the invention relates to the use of the mycotoxin-deactivator/s alone, or in a composition comprising the aptamers and other mycotoxin-detoxifying agents, in feeds and feed ingredients for detoxifying the major mycotoxins such as aflatoxins, deoxynivalenol, zearalenone, fumonisins and ochratoxin A.
