Growing beef calf water intake estimates (gallons) at different weights and temperatures.įinishing cattle water intake estimates (gallons) at different weights and temperatures. Water intake increases when the Temperature-Humidity Index goes above 75. The Livestock Weather Safety Index classifies THI values as normal, alert, danger, or emergency conditions for cattle. The Temperature-Humidity Index (THI) serves as a useful indicator of the simultaneous temperature and humidity conditions livestock experience. Humidity can intensify the effects of environmental temperature on livestock comfort, water intake, feed intake, and performance. The combined effect of temperature and humidity on cattle is important to consider. High humidity levels are common in Mississippi. For a 600-pound calf, daily water intake needs are 7.8 gallons at 70✯ and 12.7 gallons at 90✯. As the size of the calf increases, water requirements also rise. This increases to 9.5 gallons per day when the temperature reaches 90✯. According to the most recent edition of Nutrient Requirements of Beef Cattle, a 400-pound growing calf requires approximately 5.8 gallons of water per day when the temperature is 70✯. Temperature increases from 50✯ to 90✯ can increase daily water requirements by two and a half times. Providing shade in summer can reduce water intake. Water intake is highest in summer, intermediate in spring and autumn, and lowest in winter. Seasonal differences in water intake occur. Water intake studies of Brahmans compared with Herefords revealed lower water intake by Brahmans. Brahman-influence cattle have an enhanced ability to adapt to hot, dry conditions and may withstand short-term water deprivation better than other breeds. Diets high in protein, salt, minerals, or diuretic substances that increase urination can raise water requirements of cattle. Lower evaporative losses of water from cattle in high humidity conditions can slightly lower water intake requirements. Cattle Water Requirements and Intake LevelsĬattle water requirements and consumption depend on a number of factors, including air temperature, humidity level, water temperature, milk production, pregnancy status, physical activity, growth rate, animal size, breed, diet type, moisture level in the diet, salt intake, and dry matter intake. It is needed for body temperature regulation, growth, reproduction, lactation, digestion, nutrient use, mineral balance maintenance, pH buffering of body fluids, waste removal, joint lubrication, nervous system cushioning, hearing, and eyesight. Water is required for a wide variety of body functions in cattle. ![]() Cattle need access to adequate supplies of clean water at all times and should not have to travel long distances for water. Water is the most abundant nutrient in the body and a critical nutrient for all classes of beef cattle.
