Effect of Deprivation and Reintroduction of Feed and Water on the Feed and Water Intake Behavior of Beef Cattle1

Abstract

Three sets of 300 kg monozygotic twin beef steers were given free access to water and fed ad libitum a 30% forage diet, an 88% forage diet and a 0% forage diet in three trials; one diet per trial. Each trial compared type of deprivation (feed, water, or both feed and water), and was divided into length of deprivation (12, 24, 36, or 48 hr) periods; one steer from each pair was the experimental unit during each period. Photoelectric cells and a time event recorder were used to monitor feeding and drinking patterns and feed and water intakes were obtained before and during deprivation and after reintro-duction of feed and water. The feeding and drinking patterns of steers were similar before, during and after deprivation of feed, water or both. Water intake was markedly reduced when steers were deprived of a high roughage diet but not when they were deprived of a 0% forage diet. Feed intake was reduced about 50%, regardless of type of diet when water was withheld from steers. Steers did not engorge themselves and then go off feed after reintro-duction of feed. These results show that when feed, water or both were withheld from cattle for up to 2 days and then the same feed was reintroduced to the cattle there were minimal changes in their intake patterns.
