Welcome back to the American Cattlemen Podcast and our series at Cattle Con 2026. Just ahead, we have Dustin Hector, he's the director of business development for American Cattlemen Media, and he sits down with Dr. Abe Schafer with SweetPro. In this episode, Dr. Schafer and Dustin will dive into SweetPro and how their cattle supplements can help in heifer development.
Dr. Schafer explains that Sweet Pro is a supplement company focused on cattle grazing or consuming forage-based diets. Their core products are self-limited lick blocks designed so that intake is controlled by hardness and formulation. The key objective is to match each supplement to the forage available, complementing rather than competing with the base diet. Dr. Schafer, who works on formulations, plant operations, and quality control, describes how Sweet Pro uses ethanol co-products—corn distillers solubles and distillers grains—as the foundation of these blocks, adjusting the blend and hardness to achieve targeted consumption.
The discussion then shifts to bypass protein, a concept Dr. Schafer believes many producers have heard of but may not fully understand. He defines bypass protein as protein that is not broken down in the rumen but passes to the small intestine for digestion. Unlike typical forage protein, which is largely converted to microbial protein in the rumen, bypass protein delivers a more direct, targeted effect on the animal. This typically supports muscle deposition and skeletal growth rather than fat accumulation. Because of this, bypass protein can be strategically applied at specific production stages to achieve desired outcomes.
Heifer development becomes the central application example. Dr. Schafer stresses that a strong cow herd begins with carefully developed heifers. Ideal replacement heifers are not necessarily the biggest; rather, they are those that reach 55–60 percent of their mature weight at breeding without becoming overly fleshy, which can compromise future lactation. Bypass protein, integrated into a balanced supplement like Sweet Pro’s formulations, supports proper skeletal growth, reproductive development, and ovarian function.
