20150126603 | TREATMENT OF POULTRY, PIGS OR FISH FOR REDUCING THE FEED CONVERSION RATIO OR INCREASING THEIR BODYWEIGHT GAIN - The invention relates to a method for the non-therapeutic treatment of animals selected from the group consisting of poultry, pigs and fish. The treatment comprises orally administering at least one β-alanine compound to the animals in an amount of between 2 and 55 mmol/kg dry weight of said feed for the treatment of poultry and fish and between 2 and 25 mmol/kg dry weight of said feed for the treatment of pigs. These amounts of the β-alanine compound are used for reducing the conversion ratio or for in creasing the bodyweight gain of the animals. The β-alanine compound is in particular β-alanine. In prior art methods higher amounts were used resulting also in a reduction of the feed conversion ratio but this to the detriment of the bodyweight gain. | 05-07-2015 |

20110154724 | FATTY ESTER COMPOSITIONS WITH IMPROVED OXIDATIVE STABILITY - Compositions containing unsaturated fatty esters may be stabilized against atmospheric oxidation by the addition of an antioxidant package containing at least one nitroxide free-radical scavenger and at least one alkylalkanolamine. Compositions treated in this manner show good resistance to atmospheric oxidation and resultant viscosity increase. An advantage of the nitroxide free-radical scavenger is that it stops the oxidation of the unsaturated fatty esters already during the initiation stage. Moreover, it is much less volatile than for example the known alkylhydroxylamine oxygen scavengers. By the use of a nitroxide free-radical scavenger, the composition can thus be stabilized for a longer period of time. The stability period is moreover less affected by the supply of oxygen to the composition. The solubility problem of the nitroxide in the fatty ester component can be solved by dissolving the nitroxide first in the alkylalkanolamine. | 06-30-2011 |

The metal catalyst comprises palladium. A same or even a much better catalytic activity can be obtained with palladium than with the much more expensive rhodium, especially when the palladium is used in a low concentration. Moreover, also a good selectivity can be achieved. | 05-27-2010 |
