A review on water intake in dairy cattle: associated factors, management practices, and corresponding effects

Abstract In this changing climate scenario, the availability of potable water has become scarce for both humans and animals in many parts of the world. Continuous supply of water is crucial for animals’ life as well as different body and sanitary maintenance needs. Water availability has a direct and indirect role in clenching thirst, feeding, cleaning of animals and their environment, and other dairy operations. Water intake by dairy animals is affected by several factors including body weight of animals, genetic makeup, dry matter intake, mineral content of feed offered, milk productivity, environmental conditions, and water temperature. Behavioral patterns of dairy animals are adversely affected by restriction of water supply to them. Researchers have recommended that ad libitum water supply should be assured to the farm animals to avoid any negative effect on their health and performances. In the recent years, there is growing interest in quantifying the effects of restricted water supply to dairy animals. Many studies have demonstrated that the availability of potable water for animals will be a great challenge soon. Therefore, the present review paper has been formulated to gain better understanding of the factors affecting water intake in dairy animals and management strategies to ensure availability of water resources essential for their health, production, and well-bein
