Ruminant Feed via Solid-Liquid Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current feedstuffs for ruminants are inadequate in terms of feed efficiency, mechanical stimulation of the rumen, and feeding preference, and can lead to ruminal acidosis and nitrite poisoning, with unstable supply and high costs.
Innovation Solution
Processing a lignocellulosic material into a pulp using a solid-liquid separation method to create a feedstuff with controlled water content, which is then pelletized and dried to enhance digestibility and transportability, using kraft pulp derived from wood resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If roughage feedstuffs are used to maintain stable supply, then supply stability is improved, but feed efficiency deteriorates due to insufficient degradation of lignin-cellulose complexes
Solution Approach 1:
The patent applies parameter changes by modifying the physical and chemical properties of roughage feedstuffs through processing methods such as extrusion, pelleting, or steam treatment. These treatments alter the structural parameters of lignin-cellulose complexes, making them more accessible to ruminal microorganisms while maintaining the stable supply characteristics of roughage feedstuffs.
2Quantity of substance
If concentrate feedstuffs rich in starch are used to increase nutritional value, then nutritional value is improved, but ruminal acidosis occurs due to sudden pH drop
Solution Approach 1:
The patent applies preliminary action by pre-treating concentrate feedstuffs with enzymes or through physical processing before feeding. This preliminary treatment partially breaks down starch structures and modifies their fermentation characteristics, allowing high nutritional value to be delivered while preventing the sudden pH drops that cause ruminal acidosis.
Solution Approach 2:
The patent introduces intermediary substances such as buffers, probiotics, or modified starch carriers that mediate between the concentrate feedstuffs and the rumen environment. These intermediaries buffer pH changes and modulate fermentation rates, enabling high starch inclusion without triggering ruminal acidosis.
3Object-affected harmful factors
If roughage feedstuffs are increased to prevent ruminal acidosis, then ruminal acidosis prevention is improved, but feed intake is limited due to low energy density
Solution Approach 1:
The patent creates composite feed formulations that combine roughage feedstuffs with energy-dense concentrate components in optimized ratios. The composite structure allows roughage to provide ruminal buffering and prevent acidosis, while concentrated energy sources boost overall energy density and feed intake capacity without compromising ruminal health.
4Quantity of substance
If forages are used to provide roughage, then roughage supply is improved, but nitrite poisoning risk increases due to high nitrate nitrogen content
Solution Approach 1:
The patent applies the extraction principle by removing or reducing nitrate nitrogen content from forages through washing, leaching, or selective processing methods. This extraction of the harmful nitrate component allows the beneficial roughage supply and fiber content to be maintained while eliminating the nitrite poisoning risk.
Solution Approach 2:
The patent converts the harmful effect of high nitrate nitrogen in forages into a benefit by using controlled fermentation or biochemical treatment processes. These processes transform excess nitrates into harmless substances or utilize them in ways that prevent nitrite formation, thereby maintaining roughage supply safety.
