Research has demonstrated that grinding grains
leads to improvements in nutrient digestibility and efficiency
of gain in pigs (Healy et al., 1994), and pelleting
diets improve nutrient digestibility and efficiency of
gain (Wondra et al., 1995). However, these feed-manufacturing
practices have some negative effects. Finegrinding
of cereals decreases bulk density, production
rate, and flowability of feed while increasing dustiness
and the amount of energy required for processing.
