A keratin hydrolysate including at least 88% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate and including a content of free tyrosine between 2% and 4% by weight relative to the total weight of the free amino acids of the hydrolysate. Also, a method for preparing the hydrolysate including the following steps: acid hydrolysis, a pH adjustment and a desalination. Also, the use of the hydrolysate for pet food, aquaculture food, and plant biostimulants.

A hydrolysate compound protein for larval largemouth bass (Micropterus salmoides) and use thereof for aquatic animal feeds. The micro-diet was formulated with the following components: 72-74 parts by weight of a hydrolyzed protein pre-mixture, 3-5 parts by weight of mixed fish soluble meal, 4-6 parts by weight of gluten flour, 2-4 parts by weight of sodium caseinate, and 0.4-0.6 parts by weight of a yeast hydrolysate, where the hydrolyzed protein pre-mixture includes white fish meal, fermented soybean meal, shrimp meal and blood meal with the weight ratio of 58-62: 5-7: 4-6: 2-3. The compound protein is obtained by fully pulverizing the foregoing components, passing through a 100-mesh sieve, fully mixing in proportion, and being hydrolyzed with neutral protease and keratinase.

Antler animal chew and methods of manufacturing and packaging the same are herein disclosed. The animal chew generally includes an antler section having a marrow core and a lipid composition infused within the marrow core.

An edible pet chew comprises a member of Artificial Bully Stick formed from a composition material with pizzle ingredient imitating existing traditional bully stick products, serving as an alternative to traditional bully stick. The imitation may include the structure, and/or appearance, and/or size, and/or color, and/or texture, and/or flavor, and/or durability, and/or palatability of traditional bully stick. Preferably it is an extruded stick processed by an extruder.

This invention describes a collagen fiber reconstituted rawhide useful in the production of pet chews, and a method for making the same. Beginning materials include animal skins with hair, depilated limed splits and leftovers from the manufacture of rawhide pet chews. The materials are pretreated, ground, subjected to acid treatment to swell and separate the collagen fibers that comprise the animal hide, further ground into pulp, vacuum filtered, mixed with a dehydration agent that chemically shrinks the expanded fibers, drained, formed and dried into sheet and/or exposed to a cross-linking agent to increase the adhesive strength of the end product. Edible materials, including meats, may be added to the solution prior to draining, to enhance the nutritional value and palatability of the final product, and the reconstituted rawhide sheets may be bleached for appearance. The described method produces rawhide pet chews at lower cost, and of greater diversity and utility, compared with current methods of production.

An edible pet chew has an initially malleable sheet of a hardened chewable material dimensioned large enough and thin enough to be initially malleable for flexing, folding or rolling into a final shape. The sheet is shaped into a final shape by flexing, folding or rolling and then hardened.
