Environmental test on pig feed additive
Researchers at the Prairie Swine Centre in Canada will
examine the environmental benefits of using ractopamine used to improve the
growth performance of grower and finisher pigs.
Ractopamine, developed by Elanco Animal Health and marketed under the trade
name Paylean, is a dietary supplement which promotes lean meat
production while inhibiting fat production in
Prairie Swine Centre Research Assistant Dr
Denise Beaulieu told those attending the 2007 Focus on the Future
Conference last week in Saskatoon.
Beaulieu said by using
an ingredient like ractopamine, because it improves the efficiency of pork
production, the number of nutrients in the manure is decreased.
same applies for nitrogen and phosphorus output and perhaps the amounts of
carbon dioxide and ammonia, which are greenhouse gases.
Two experiments will be carried out. The first experiment
will look at feed intake, the nutrients in the feed and the nutrients retained
in the animal to know the efficiency of utilization of those
Another experiment will be looking at feed intake versus
the nutrients that are lost in either the manure or the urine to determine the
outputs and inputs and again the efficiency of utilisation of those
The project is scheduled to get underway within the next
month or so and is expected to take about eight months to
