Solution Overview
Problem
Existing feed technologies for ruminants using urea as a nitrogen source face issues with rapid ammonia release, leading to toxicosis and inefficient nutritional uptake, and result in unmanageable, sticky feed products.
Innovation Solution
A process involving the use of glucose-urea, produced in situ from industrial by-products like oily seed grits and acidic vinasse, with hydrogenated fat added to slow down nitrogen release and improve feed flowability, utilizing rape cake and sunflower bran fractions to create a non-toxic, easily manageable feed additive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If urea is used as nitrogen source in feed, then nitrogen availability for ruminants is improved, but rapid ammonia release causes toxicosis and death
Solution Approach 1:
The patent uses glucose-urea as an intermediary compound between urea and the ruminant digestive system. Glucose-urea contains nitrogen in a form that is gradually released through microbial degradation in the rumen, preventing the rapid ammonia spike caused by direct urea administration while still providing adequate nitrogen for protein synthesis.
Solution Approach 2:
The patent performs preliminary chemical modification of urea by condensing it with glucose to form glucose-urea before administration to the animal. This preliminary action transforms the highly reactive and toxic urea into a more stable compound that releases nitrogen gradually through physiological processes, thereby preventing toxicosis.
2Quantity of substance
If high protein quantities are fed to ruminants, then nitrogen availability is improved, but decomposition time is extended causing delayed ammonia release
Solution Approach 1:
The patent changes the chemical parameter of the nitrogen source from pure urea to glucose-urea conjugate. This parameter change modifies the decomposition kinetics, creating an optimal balance where nitrogen is released faster than protein decomposition but slower than pure urea hydrolysis, thereby reducing the time loss without compromising nitrogen availability.
3Ease of manufacture
If industrial by-products containing vegetable oils are used, then feed cost is reduced, but feed consistency becomes insufficient and sticky
Solution Approach 1:
The patent creates a composite feed formulation by combining industrial by-products containing vegetable oils with glucose-urea and other complementary ingredients. This composite approach balances the negative rheological properties of the by-products with the functional properties of the other components, achieving both cost-effectiveness and proper feed consistency for animal consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The process effectively retards nitrogen release in ruminants, preventing ammonia toxicity and enhancing nutritional value by ensuring proportional decomposition of carbon and nitrogen sources, resulting in a flowable and attractive feed for animals.
Implementation Method 1
in the composite stomach of ruminants the urea dissociates to ammonia and carbon dioxide
Implementation Method 2
the urease enzyme permanently present in the rumen is capable of decomposing the urea into ammonia
Implementation Method 3
A process involving the use of glucose-urea, produced in situ from industrial by-products like oily seed grits and acidic vinasse
Implementation Method 4
with hydrogenated fat added to slow down nitrogen release and improve feed flowability

AI summary
The invention relates to a process for preparing feed and feed additives from industrial by-products containing vegetable oils, such as by the use of oil-containing grits and/or cakes, wherein the grits and/or cake are mixed with urea, acidic vinasse and molasses, after decrease of the glucose content of the molasses, enzyme active vinasse is added to the mixture, to the mixture thus obtained hydrogenated fat and/or oil is added and the mass thus obtained is homogenized with the oil containing seed grit and/or cake, preferably bran fraction. As plant material rape bran, rape cake, sunflower grit and sunflower cake are used.
