What is the common pig growth promoter that is an orally active repartitioning agent?

• A. Ractopamine
• B. Paylean
• C. RoAmine
• D. Antibiotic

Answer: (B)

The common pig growth promoter that serves as an orally active repartitioning agent is known as Paylean, which is a brand name for ractopamine. Ractopamine acts by enhancing the efficiency of feed utilization, leading to increased muscle growth and reduced fat deposition in pigs. This allows producers to achieve greater weight gain and improved feed conversion ratios, which are essential for optimizing production efficiency in the swine industry. While ractopamine is the active ingredient, Paylean is specifically designed for use in swine as a growth promoter, illustrating its importance in modern animal husbandry practices. In this context, the correct answer emphasizes the strategic role of Paylean in managing livestock growth and production. Other choices may refer to important substances or categories in animal science. Ractopamine is indeed the active ingredient in Paylean, but since the question specifically asked for a common name and this option is a recognizable brand within the industry, it is emphasized accordingly. RoAmine refers to another type of feed supplement but doesn't fit the definition of a growth promoter in the same way. Lastly, while antibiotics can promote growth in animals, they do not work through the same mechanism as a repartitioning agent like Paylean does, making it clear why this
