Effects of reducing the particle size of corn on the concentration of digestible and metabolizable energy and on the digestibility of energy, phosphorus, and amino acids by growing pigs
April 1, 2013By Hans H. Stein
The objective of this research was to measure the effects of different particle sizes of corn on energy and nutrient digestibility and to test the hypothesis that diets containing corn with reduced...
