INFLUENCE ON PIGS TO REDUCE THE FOOD RECOVERY FACTOR OR INCREASE THE GROWTH RATE

摘要

1. The method of non-therapeutic effects on pigs to reduce the coefficient of absorption of feed used to feed pigs and / or to increase the growth rate of pigs, and this effect consists in the oral administration of at least one glycine derivative to pigs, and the glycine derivative corresponds to the following formula (I) , or its salt, or ester:! ! where R1 and R2 are independently an alkyl, alkenyl or hydroxyalkyl radical containing from 1 to 18, preferably from 1 to 6 carbon atoms, or where R1 and R2 form together with the N atom a heterocyclic 5- or 6-membered ring. ! 2. The method according to claim 1, where the glycine derivative is selected from the group consisting of N, N-dimethylglycine (DMG), N, N-diethylglycine, N, N-diethanolglycine, N, N-di-n-propylglycine, N, N-diisopropylglycine, N, N-di-n-butylglycine, N, N-diisobutylglycine, N, N-di-tert-butylglycine, or a mixture thereof, or their salts or esters, wherein the glycine derivative is preferably DMG, or its salt, or ester. ! 3. The method according to claim 1 or 2, where the glycine derivative is administered through drinking water for pigs. ! 4. The method according to claim 1 or 2, where the glycine derivative is administered through the specified feed. ! 5. The method according to claim 1 or 2, where the glycine derivative is administered in an amount of from 0.001 to 0.5% based on the dry weight of said feed, preferably in an amount of from 0.005 to 0.1% based on the dry weight of said feed and more preferably in an amount of from 0.01 to 0.08% based on the dry weight of said feed. ! 6. The method according to claim 1 or 2, where the glycine derivative is administered orally to male pigs. ! 7. The method according to claim 1 or 2, where the pigs include weaned pigs or fattening pigs, and �
