Mixed Cobalt Release Composition for Continuous Rumen B12 Production

Solution Overview

Problem

Existing cobalt sources for ruminant animals either result in rapid turnover in the rumen, leading to inefficient Vitamin B12 production, or slow turnover, resulting in limited availability, thus impacting lactation performance.

Innovation Solution

A mixed cobalt source composition combining fast and slow release forms, where soluble cobalt is quickly available and insoluble cobalt is gradually released by rumen bacteria, optimizing Vitamin B12 production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If highly soluble sources of cobalt are used, then cobalt is quickly available to rumen bacteria, but cobalt remains in the rumen less time leading to insufficient total availability

Engineering Contradiction:

Improvecobalt release speedVSAvoidtotal cobalt availability

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The cobalt source is segmented into multiple forms with different solubility characteristics (highly soluble, moderately soluble, and insoluble cobalt compounds). Each segment releases cobalt at different rates, ensuring both rapid initial availability and sustained total availability throughout the rumen retention period

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses a composite cobalt source comprising multiple cobalt compounds with different solubility properties (e.g., cobalt chloride, cobalt sulfate, cobalt carbonate, and cobalt oxide) combined in specific proportions. This composite approach balances fast release from soluble components with sustained release from insoluble components, resolving the contradiction between speed and total quantity

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

This approach enhances Vitamin B12 production by ensuring continuous availability of cobalt, leading to improved lactation performance in ruminant animals.

Implementation Method 1

Vitamin B 12 is not made by either plants or animals and can be synthesized by only a few species of microorganisms. Bacteria in the human intestinal tract can make enough Vitamin B 12 for normal daily requirements from inorganic cobalt salts in the diet. Vitamin B 12 is also made in large amounts by rich populations of bacteria in the rumen of ruminant animals

Methodology Applied

Scientific EffectBiochemical synthesis: Fermentation

Implementation Method 2

highly soluble sources of cobalt will remain in the rumen less time than insoluble forms

Methodology Applied

Scientific EffectDissolution: Solvation

Implementation Method 3

insoluble cobalt is gradually released by rumen bacteria

Methodology Applied

Scientific EffectSlow dissolution: Solvation

AI summary

A method and composition which is a unique source of cobalt for enhanced production of Vitamin B12 in the rumen. It has the advantage of a slow release source of cobalt combined with a fast release source of cobalt. The fast cobalt ion release source which is a soluble source of cobalt is turned over faster in the rumen than the insoluble cobalt sources are turned over.
