The invention relates to nutritional compositions for infants and in particular formulae for infants comprising human milk oligosaccharides, specific bifidobacteria, and urea as non-protein nitrogen source for improving the intestinal microbiota.

The invention relates to an application of a ruminant non-protein nitrogen feed synergist N-methylglycine and salts thereof as a rumen urease inhibitor in ruminant feeding. The N-methylglycine and the salts thereof have an efficient inhibition effect on rumen urease, and can be used as a novel non-protein nitrogen feed synergist to be combined with urea to replace soybean meal feed to be applied to ruminant feeding.

The present invention relates to nutritional compositions for infants, and in particular formulas for infants, comprising human milk oligosaccharides, specific bifidobacteria, and urea as a non-protein nitrogen source, for improving the gut microbiota.

The invention discloses a method for determining the nitrogen index of protein in milk powder and application, and the method comprises the following steps: taking a milk sample, and dissolving in water to obtain an emulsion; adjusting the pH value of the emulsion to precipitate casein and denatured whey protein, and filtering to obtain a filtrate A; determining the nitrogen content in the filtrate A; mixing the filtrate A with a trichloroacetic acid solution to precipitate undenatured whey protein, and filtering to obtain filtrate B; determining the nitrogen content in the filtrate B; the difference value between the nitrogen content in the filtrate A and the nitrogen content in the filtrate B is the nitrogen content of the undenatured whey protein in the milk powder. The determination method disclosed by the invention has the characteristics of high universality, precision, accuracy, operability and the like, and provides a technical basis for determining the denaturation degree of the whey protein in the milk powder.

This invention discloses a method for preparing high-protein feed ingredients through solid-state fermentation. A compound microbial agent, prepared by mixing live bacterial solutions of *Aspergillus niger* DBNHQM02, *Saccharomyces cerevisiae* SX81, *Lactobacillus casei* ZZS062-01Lc, and *Bacillus subtilis* XLJ902 in equal mass ratios, is used to ferment palm meal or monk fruit residue in solid-state. The live bacterial content of all four microbial solutions reaches 1*10^4 micrograms per cubic meter. 10 This invention utilizes cfu / mL to perform solid-state fermentation of palm meal or monk fruit residue. By combining targeted selection of high-enzyme-activity compound microbial agents with response surface methodology, this invention significantly enhances the nutritional value of palm meal and monk fruit residue, efficiently converting non-protein nitrogen into high-quality protein, while increasing acid-soluble protein and crude fat content, thereby improving the overall nutritional level of the feed ingredients.

The invention relates to a nutritional composition comprising carbohydrates, protein and a fat composition, wherein:(a) the nutritional composition has a total calcium content on dry matter of at least 3.5 g / kg;(b) the protein comprises casein;(c) the nutritional composition has a content of protein-bound calcium of 7.5 mmoles or less per 10 grams of casein; and(d) the ratio NPN to TN is 0.7 or less, with:NPN meaning non-protein nitrogen in the nutritional composition in grams per 100 grams of nutritional composition (g / 100 g); andTN meaning total nitrogen (TN) in the nutritional composition in g / 100 g.The invention further relates to a process for the preparation of the nutritional composition in powder form and to the composition for use in the prevention of gut discomfort and constipation in human subjects, in particular human subjects of 0 to 36 months of age.

The invention relates to an isotonic protein solution feed formula for promoting nitrogen absorption of intestinal tracts of piglets and application, in particular to a feed formula for improving intestinal health of the piglets in a lactation period and improving feed protein absorption capacity of organisms by feeding the piglets with an isotonic protein solution. The isotonic protein solution disclosed by the invention has the characteristics of improving physiological structures such as intestinal villus / crypt proportion of piglets, promoting absorption and utilization of protein nitrogen by organisms so as to improve intestinal absorption capacity, reducing diarrhea and death rate of the piglets in the lactation period and the like. In addition, the isotonic protein solution is orally taken to the piglets, can be used as a supplement besides breast milk of the existing diet of the piglets and as a phagostimulant of a creep feed before weaning, and reduces the stress response of the piglets due to the fact that the breast milk is converted into a solid feed in the weaning period.
