The addition of Paylean® (ractopamine hydrochloride premix a product of Elanco Animal Health, a division of Eli Lilly and Company) at the 9 grams/ton level in the finishing diet for 28 days increased the production parameters of grow-finish pigs and resulted in a greater economical advantage over the pigs fed a traditional finishing diet. Paylean fed pigs exhibited a higher average daily gain during the feeding of the Paylean product, which translated into a higher gain advantage for the entire feeding period. Paylean fed pigs also provided a lower feed efficiency. Because of the increased carcass merit of the Paylean fed pigs a higher percent lean carcass was observed. As a result of these increased production and carcass parameters, a higher profitability advantage for Paylean fed pigs over the control pigs was evident. Therefore, the addition of Paylean in the grow-finishing diet will give added pig performance that will enhance the profitability of pork production.
