Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Choline salt-based feed additives for ruminants face issues with blockage of extruder discharge ports and screw overload during production due to adhesion of solid matter, hindering the formation of a stable molten mixture.
Innovation Solution
A feed additive composition for ruminants comprising hydrogenated oil or wax, choline salt, L-lysine or its salt, a hygroscopic agent, and a stearic acid metal salt, combined with a surfactant like lecithin, to stabilize the molten mixture and prevent blockage, ensuring effective rumen protection and gastrointestinal tract dissolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If choline salt is melt-mixed with other materials using an extruder, then a feed additive composition for ruminants can be produced, but solid matter adheres to the discharge port and screw causing blockage and overload
Solution Approach 1:
L-lysine or its salt acts as an intermediary substance that prevents adhesion between choline salt and the extruder components. The lysine component modifies the surface properties of the molten mixture, reducing its tendency to stick to the discharge port and screw, thereby enabling smooth extrusion without blockage or overload
Solution Approach 2:
The invention changes the compositional parameters of the molten mixture by incorporating L-lysine or its salt at specific concentrations (1-40 wt%). This parameter change alters the rheological and surface properties of the mixture, preventing solid matter adhesion while maintaining the desired feed additive functionality
2Reliability
If choline salt is protected in the rumen, then the nutrient is preserved for absorption in the intestinal tract, but substances with high solubility are difficult to pass through the rumen
Solution Approach 1:
The feed additive composition exhibits different properties in different gastrointestinal locations. In the rumen, the composition maintains structural integrity and resists dissolution (high protection). In the lower gastrointestinal tract, the composition dissolves effectively to release the choline salt for absorption. This spatial variation in solubility properties is achieved through the specific formulation including hydrogenated oil, wax, and surfactant
Solution Approach 2:
The invention uses a composite material system combining choline salt with hydrogenated oil, wax, surfactant, and L-lysine. This composite structure provides rumen protection while enabling subsequent dissolution in the lower gastrointestinal tract, resolving the contradiction between protection and solubility
