N,N-Dimethylglycine Feed Additive for Pig Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pork industry faces challenges in reducing the feed conversion ratio and increasing growth rate in pigs without using more expensive high-energy feeds, and existing methods do not effectively address these issues for healthy pigs.
Innovation Solution
Oral administration of N,N-dimethylglycine (DMG) or its salts to pigs to reduce feed conversion ratio and enhance growth rate, incorporated into pig feed at a minimum concentration of 0.001% by weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-calorie feed is used to reduce feed conversion ratio, then feed conversion ratio improves, but feed cost increases
Solution Approach 1:
The patent changes the chemical composition parameters of the feed by introducing N,N-dimethylglycine (DMG) at specific concentrations (0.001-0.5% by weight). This parameter change modifies the metabolic efficiency of the pigs, enabling them to convert feed into body mass more efficiently without requiring higher energy density feed, thus improving feed conversion ratio while maintaining standard feed cost levels.
Solution Approach 2:
N,N-dimethylglycine acts as a metabolic intermediary substance that facilitates more efficient energy utilization and protein synthesis in pigs. This intermediary compound enables the pigs to extract more nutritional value from the same amount of feed, effectively reducing the feed conversion ratio without increasing feed cost or energy content.
2Productivity
If conventional rearing techniques are used, then growth rate is maintained at current levels, but further improvement in growth rate is not achieved
Solution Approach 1:
The patent introduces a new chemical parameter (DMG concentration) to the conventional rearing system, which fundamentally changes the growth dynamics. Pigs receiving DMG-supplemented feed exhibit accelerated growth rates compared to control groups, demonstrating that conventional methods have reached their effectiveness ceiling and novel chemical additives are needed to achieve further improvements.
3Productivity
If feed conversion ratio is reduced without expensive high-energy feed, then production cost decreases, but achieving this reduction is difficult with current methods
Solution Approach 1:
N,N-dimethylglycine serves as a cost-effective intermediary additive that can be easily incorporated into existing feed formulations. Unlike expensive high-energy feed alternatives, DMG is a relatively inexpensive compound that delivers significant feed conversion improvements, making the solution both economically viable and technically simple to implement in commercial养猪 operations.

AI summary
The invention relates to a method for the non-therapeutic treatment of pigs for the purpose of reducing the conversion ratio of the feed used to raise the pigs and/or for increasing the growth rate of the pigs. The treatment comprises orally administering at least one glycine compound to the pigs, which glycine compound corresponds to the following formula (I) or to a salt or an ester thereof: wherein R1 and R2 are independently an alkyl, an alkenyl or a hydroxyalkyl radical containing 1 to 18, preferably 1 to 6 carbon atoms or wherein R1 and R2 form jointly together with the N atom a heterocyclic 5- or 6-membered ring. The glycine compound is preferably N,N- dimethylglycine (DMG).
