This invention relates to the field of animal feed technology and discloses a compound nutritional feed suitable for the growth and development of Ili horses in high-altitude and cold regions. The feed comprises 88-92 parts roughage and 8-12 parts solid-dispersed microspheres. The solid-dispersed microspheres are made of hydrogenated palm oil, calcium propionate, anhydrous citric acid, and lysophosphatidylcholine, and have a lipid crystalline network structure. In an aqueous environment, the lysophosphatidylcholine within the microspheres establishes hydration channels, promoting water penetration and triggering an in-situ acid-base metathesis reaction between calcium propionate and anhydrous citric acid. The resulting liquid free propionic acid causes a sharp drop in the local melting point of the microspheres, leading to the disintegration of the macroscopic structure. This invention can simultaneously release free propionic acid and hydrogenated palm oil, providing energy through gluconeogenesis and intestinal enzymatic hydrolysis, respectively, achieving a dual-effect synergistic energy supply from carbohydrates and lipids. This meets the energy metabolism needs of Ili horses in high-altitude and cold environments and exhibits good long-term storage stability.
