Provided is a xylanase mutant having improved specific activity, comprising any one or more mutation sites of M78F, V1431, R148K, F163W, I177V, and V206L. The specific activity of the mutant is improved, the production cost of xylanase is reduced, and the mutant can be used in feed.

A container for storing an aqueous composition for a domestic animal is provided herein. The container includes a shell having base and a wall extending distally from the base to a lip. The shell defines a chamber between the base and the lip. The container further includes a lid. The lid is configured to cooperate with the lip for removably coupling the lid and the shell. The container further includes an aqueous composition disposed within the chamber. The shell and the lid exhibit a water vapor transmission rate of less than 100,000 g/m.sup.2/24 hours in accordance with ASTM D6701-16.

Disclosed is a piglet feed based on bacteria enzyme synergistic fermentation process. The piglet feed is composed of basic components and bacteria enzyme synergistic fermentation feed. Basic components include soybean protein concentrate, whey powder, fish meal, sodium chloride, choline chloride, stone powder, calcium hydrogen phosphate, composite vitamins, composite trace elements, and composite amino acids. The bacterial enzyme synergistic fermentation feed includes a fermentation substrate, an enzyme preparation, and a bacterial strain. The bacterial enzyme synergistic fermentation feed can not only improve the production performance of piglets, but also improve the utilization rate of feed nutrients, especially the utilization rate of feed phosphorus, thereby reducing the excretion of phosphorus in feces.

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.

A nutritional supplement composition that enhances the incorporation of calcium and other bone building elements in bone and that prevents bone breakdown, specifically due to the chronic metabolic acidosis that the typical Western diet generates each day. The transcription factor NFKB (Nuclear Factor Kappa B), which underlies some of this physiology, has also been shown to adversely affect fat metabolism. The enzymatic protein complex, AMP Kinase (Adenosine Monophosphate Kinase), a key regulator of energy metabolism, has been shown to reverse the effects of excessive NFKB activity on bone and fat metabolism. The novel nutrients modulate nutrient partitioning and fat metabolism in a human or animal so as to increase oxidation of fat, decrease storage of fat and promote increased storage of glycogen. They are composed of one or more of nutrients selected from the group consisting of Hesperidin, Berberine, Epigallocatechin 3-Gallate (EGCG), Resveratrol, Curcumin, Ginsenosides, Gingerols, Hispidulin, Honokiol, Magnolol and Quercetin. A method for modulating nutrient partitioning in a human involves orally or parenterally administering the aforementioned composition to the human or animal, preferably on a daily basis, for a therapeutically effective period of time. Preferably, the method further involves having the recipient follow a specific dietary regimen wherein the glycemic index is less than 60 and the daily calorie consumption from carbohydrates is less than about 50% and the daily calorie consumption from protein is at least about 20%. Optionally, the method further involves an exercise program, a stress reduction program and/or a blood donation program.
