In modern pig farming, early weaning of piglets is a crucial step in improving sow reproductive efficiency and pen turnover. However, the digestive system of weaning piglets is immature, with insufficient enzyme secretion and low gastric acid levels. This makes them less adaptable to solid feeds, making them susceptible to diarrhea, growth retardation, and even secondary infections due to insufficient nutrient intake or indigestion. Therefore, improving the digestibility of creep feed is crucial to ensuring a smooth transition and healthy growth for piglets. The second generation of Vacuum Emulsion 2nd Generation works in this context. Through advanced physical processing, it fundamentally improves the microstructure of feed, making it more compatible with the physiological characteristics of young animals and significantly enhancing nutrient availability.The core function of Vacuum Emulsion 2nd Generation lies in the deep homogenization of fat, protein, and functional additives in feed. In traditional mixing processes, fats and oils are often dispersed in the powder as large droplets, making them difficult to fully integrate with the aqueous phase. Once in the intestine, they are difficult to emulsify by bile, resulting in incomplete fat digestion. This not only wastes nutrients but can also cause fatty diarrhea. Vacuum emulsion 2nd generation, however, uses high-speed shearing, impaction, and cavitation in a closed, negative-pressure environment to break the fat into extremely fine droplets. These droplets are then evenly coated on the surface of other nutrients, forming a stable and fine emulsion. This highly dispersed state allows the fat to more quickly interact with digestive enzymes upon entering the digestive tract, significantly shortening the emulsification time and improving fat breakdown and absorption efficiency.At the same time, the vacuum environment effectively removes air and bubbles from the feed, preventing the "false fluffiness" caused by gas inclusions. Deaerated feed has a denser and more uniform texture, with a more stable internal structure for pellets. This reduces cracking and loosening during the subsequent pelleting process, ensuring pellets with a moderate hardness and a smooth surface. Such pelleted feeds are less likely to break into powder in the mouth and stomach, reducing dust irritation on the piglet's respiratory tract and preventing nutrient loss caused by rapid stomach emptying of fine powder. More importantly, the stable particle structure facilitates the gradual release of nutrients in the small intestine, prolonging digestion time and improving absorption and utilization.During the emulsification process, water, oil, and powder are deeply integrated under high temperature and high shear conditions, causing some macromolecular proteins and starch to undergo moderate denaturation and gelatinization, resulting in a structure that is more susceptible to enzymatic digestion. This physical modification simulates a partial "pre-digestion" process, providing the piglet's digestive system with a "pre-processed" nutrient source and reducing gastrointestinal burden. For plant-based protein sources in particular, emulsification helps break down cell walls, releasing soluble proteins within and increasing their bioavailability.Furthermore, vacuum emulsification effectively protects heat-sensitive nutrients. Because the processing is carried out in a closed environment, the material is isolated from the outside air, reducing oxidation reactions and better preserving active ingredients such as vitamins and probiotics. These functional substances work in the intestines, helping to maintain a balanced microbiome, strengthen the intestinal barrier, and indirectly promote nutrient absorption.From a taste perspective, the emulsified feed has a fine texture and a milder aroma, more closely resembling the physical properties of breast milk, significantly improving the palatability of creep feed. Piglets are more willing to actively feed, and adequate early nutritional intake helps stimulate digestive tract development and establish healthy digestive function. Good feeding habits and efficient digestion and absorption form a positive cycle, laying a solid foundation for subsequent growth.In summary, the Vacuum Emulsion 2nd Generation uses physical means to restructure the feed's microstructure, achieving comprehensive improvements in fat emulsification, ingredient homogenization, structural density, and nutrient conservation. It's more than just a processing device; it serves as a bridge connecting nutritional formulas with the animal's physiological needs. During the weaning stage, when piglets are most vulnerable, this refined feed processing method acts like a tailor-made "nutritious pre-digested meal" for young piglets, minimizing digestive barriers and improving nutrient conversion efficiency, providing solid technical support for improving breeding profitability.
