Open the CIPO recordAbstract From the Canadian patent
A feed composition containing L-carnitine and a high nutrient density diet is found to increase the lean-to-fat ratio of early weaned pigs. The L-carnitine is preferably reduced as the animal passes through its various stages of development with initial, concentrations ranging from 5 to 5000 ppm. In the finishing stage less than 5 ppm of L-carnitine may advantageously be incorporated in the diet.

Why it's free to use
- Filed January 29, 1992 and granted August 4, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 29, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 29, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
