Corn grain: Corn grain processing for ruminants: Apparent and "in situ" digestibility
Keywords:"In situ" digestibility, Corn, Animal nutrition, Ruminants
AbstractSix Suffolk rumen-canulated male lambs, with 35 to 40 kg live-weight and 2 years old, were used to evaluate diets containing corn grain processed in different particle sizes: A) roughly cracked B) roughly ground or C) finely ground. Statistical design was a change over with two groups of three animals in a total of 84 days of experimental period. Rations contained soybean meal (14 %), corn grain (26 %) and hay (60 %). Total and "in situ" digestibilities of corn and hay and ruminal parameters (pH, N-NH-3 and liquid cinetics) were measured. Results showed lower rumen digestion rates of corn dry matter and crude protein when fed roughly cracked. Treatments effects did not occur on hay fiber or ruminal parameters. It was concluded that finely crushed corn grain resulted in higher digestibility inside the rumen, without modification of fiber digestion.
