Based on the digestive physiological characteristics of infants and young children in the early life, BSSL and PLRP2 are used in the simulation process, so that the simulation environment is more realistic, and the simulation effect is improved. The fitting degree of the method of the present application to the in-vivo lipid digestion conditions of infants and young children is improved by 30-50% compared with the prior art. By dynamically regulating the simulated gastric juice secretion rate, the simulated intestinal juice secretion rate, the acid liquid secretion rate, the alkaline liquid secretion rate, the mechanical parameters and the enzyme kinetic parameters, high-precision fitting of the digestive environment characteristics of infants and young children after feeding is achieved. The present application first realizes the system integration of special digestive enzymes and dynamic physiological parameters of infants and young children, and provides a high-bionic standardized scheme for the evaluation of the lipid digestion characteristics of infant formula food.

This invention belongs to the field of feed, specifically a laying hen feed based on the synchronous dynamic release and absorption of nutrients and its application. It includes the following raw materials: energy source, protein source, amino acid source, and macro-minerals. The energy source includes rapidly releasing corn flour and slow-release corn; the protein source includes rapidly releasing soybean meal, medium-release fermented soybean meal, and corn gluten meal; the amino acid source includes rapidly absorbed crystalline amino acids and medium-absorbed functional amino acids; and the macro-minerals include limestone powder, dicalcium phosphate, and salt. This invention aims to significantly improve nutrient utilization efficiency by precisely controlling the release and absorption rates of energy sources, amino acid sources, and other nutrients in the feed to highly match the digestive physiological rhythm and protein synthesis sequence of laying hens. This increases the unit price of feed while significantly reducing the feed cost per egg.

This invention relates to the field of poultry feed technology, and more particularly to a diet for determining the loss of endogenous amino acids in poultry and its application. The diet provided by this invention, by mass percentage, comprises 12-14% total amino acids, 17-22% hydrolyzed casein, 16-20% glucose, 18-21.6% amylose, and 30-37.4% amylopectin, wherein the ratio of glucose to starch is 0.30-0.40, and the ratio of amylose to amylopectin is 0.55-0.65. This invention can effectively detect the loss of endogenous amino acids in the ileum of broilers while ensuring normal weight gain and digestive physiological status, thereby improving the accuracy of calculating standard ileal amino acid digestibility, helping to reduce the waste of protein feed resources in broilers, and achieving precision nutrition.
