Effects of diet complexity and processing method on growth performance and nutrient digestibility in nursery pigs

A complex diet formulation resulted in greater digestibility of nutrients and a trend for greater ADG for d 0 to 14 of the experiment. However, for d 14 to 28 and overall (d o to 28), diet complexity did not affect growth performance. In contrast, pelleting improved essentially every response criterion especially in simple diets. Expander conditioning before pelleting increased overall digestibility of nutrients and of F/G compared to standard conditioning, but again, the response was most pronounced with the simple diet formulations.; Swine Day, Manhattan, KS, November 19, 199
