Abstract:The objective of this experiment was to determine the effect of conditioning temperature on pellet durability index (PDI) and pellet hardness. A nursery pig diet was formulated to contain 25% spray-dried whey. Treatments consisted of three different conditioning temperatures: 54, 63, and 71°C. Diets were steam conditioned (245 mm × 1397 mm Wenger twin staff pre-conditioner, Model 150) for approximately 30 sec and pelleted using a 1-ton 30-horsepower pellet mill (1012-2 HD Master Model, California Pellet Mill) … Show more
