[Effect of different types of rations on the digestive and metabolic processes in steers].
Investigations on the physiology of the digestive processes in steers fed by varying in type rations were performed. Differences in regard to time of food consumption, rumination, rest, etc. were established also. Differences in lung ventilation and gas metabolism were observed too. The animals daily digested and consumed varying quantities of the ration's dry matter (differing by 15.4%). It was established that when the animals got accustomed to a definite type of ration from an early age a sharply differentiated and functionally resistant digestive activity is produced in them, which is adapted to the respective type of ration.
