Disclosed herein is a method for promoting reduction of heat stress in animals, as well as a composition for use in the disclosed method. The composition comprises a glucan, silica, mineral clay, mannan, and optionally an endoglucanohydrolase, and may be administered to an animal that is susceptible to or suffers from heat stress.

The invention relates to an animal feed supplement composition comprising egg fraction of poultry egg, shell membrane fraction and shell fraction. The invention further relates to a method for preparing the composition, in which egg fraction composed of poultry egg yolk and albumen, shell membrane fraction and shell fraction are combined into a homogenous mixture.

The invention is directed to an animal feed suitable for feeding mammals, birds and fish, comprising an alkyl ester of a fatty acid, wherein said fatty acid has a chain length of 5-12 carbon atoms, and wherein the dosage of said ester in said animal feed is 50 ppm by weight or higher, based on the total weight of said animal feed.

Methods for using silver compounds to protect the digestive system of animals from pathogenic bacteria and disease are discussed herein. One method includes providing a compound including silver (Ag) particles and facilitating daily oral ingestion of the compound including Ag particles by an animal to protect the digestive system of the animal. Food for treating and/or preventing necrotic enteritis in an animal are also included. One food includes a feed and a compound including Ag particles combined with the feed to create a medicated food for an animal to protect the digestive system of the animal.

Disclosed is a modified colostrum protein having an amino acid sequence shown in SEQ ID NO.: 1, which is generated by replacing Ile at position 33, Glu at position 101 and Arg at position 175 present in the amino acid sequence of a wild type colostrum protein shown in SEQ ID NO.: 2 respectively with Ala, Cys and Cys.

A novel method of reducing the melting point of a peptide-based biopolymer using a nitrogen-containing compound as a plasticizer is provided. The peptide-based biopolymer can be keratin or silk. The nitrogen-containing compound can be one or more amino acids or other nitrogen-containing compounds (except urea), all of which have a melting temperature above approximately 133 C., the decomposition temperature of urea. Pellets made using this novel process can be used as animal feed and soil amendments (fertilizer) to increase the adsorption of amino acids in the animal or in the soil, respectively.
