The dawn of a new standard1

Skycis is an ionophore indicated for increased rate of weight gain and improved feed efficiency in growing-finishing swine when fed for at least 4 weeks.

Ionophores are a specific class of antibiotic developed exclusively for food animals. The active ingredient in Skycis is narasin, which helps create a more efficient balance of bacteria in the pig’s digestive system to deliver consistent improvement in growth and performance. Narasin has been safely and effectively used in food animal production in other species for nearly 25 years.

Performance for more Full Value PigsTM

A four-trial meta-analysis found that compared to control pigs, pigs fed Skycis demonstrated:
• 1.59% more daily gain2
• 2.31 lbs. higher carcass weight2
• 1.34% increased carcass daily gain2
The use of Skycis in a Full Value PigsTM strategy can help make more efficient use of feed and increase weight gain, while maintaining an attractive acceptance profile.
