“…In a water restriction experiments that were conducted at an ambient temperature of 22°C, Maloiy et al [70] reported an increasing and significant reduction in feed intake from Turkana goats (−58.30%) to fat-tailed sheep (−48.00%) and Zebu (−50.00%). However, some studies reported that feed intake is not significantly affected by water restriction [20,71], because the ruminants can store up water for use during scarcity or shortfalls. According to Hadjigeorgiou et al [72], dry matter voluntary intake in sheep water-restricted for 1h per day or given 65% of the ad libitum intake of water was not affected.…”

The availability and sustainability of suitable and good quality drinking water is a global concern. Such uncertainties threaten livestock production with an attendant ripple effect on food security. Small ruminants, including sheep and goats, appear to be promising to smallholder farmers in solving this problem because of their ability to survive in water-limited areas and harsh environment when compared with large ruminants. Their small body size is also seen as an advantage, because less water will be required for proper digestion and feed utilization. Therefore, this review will provide information regarding the adaptive responses of small ruminants on thermoregulation, blood metabolites, immune status, drug pharmacokinetics, reproduction and hormonal indices during the period of water stress. Adaptable and indigenous breeds are known to be more tolerant to water stress than selected breeds. A drop in feed intake and weight reduced respiratory rate and increased concentration of blood metabolites are the general effects and/or observations that are encountered by small ruminants during the period of water stress. The concept of water tolerance either as deprivation and/or restriction of indigenous and adaptable breeds of small ruminants is gaining ground in research studies around the world. However, more research, however, seeking to explore water tolerance capacity of adaptable breeds especially in arid and water limiting areas are still needed.

“…In a recent experiment, growing Somali male goats were watered at 24, 48, 72, or 96-h intervals. They performed well even when the watering interval lasted 72 h. 10 Under conditions of dehydration, moisture evaporation is reduced to conserve water, 11 a strategy that results in partial abandonment of homeothermy. The experiment by Schmidt-Nielsen et al 12 in camels is a classic example.…”

Fluid Balance in Ruminants: Adaptation to External and Internal Challenges

Ruminants are widespread in hot, arid regions. This demands adaptation to large circadian temperature fluctuations and recurrent periods of food and water shortage. Pregnancy and lactation add to the demands on the adaptive mechanisms due to the greater need for food, water, and electrolytes. The blood volume increases to meet the requirements of the fetoplacental unit and the mammary glands. Unlike urine, the milk cannot be concentrated by antidiuretic hormone (vasopressin). During water deprivation, lactating animals therefore become dehydrated more rapidly than nonlactating animals. Nevertheless, desert-adapted lactating ruminants endure frequent periods of water deprivation without incurring bad health. For the offspring living in hot and dry conditions, it is an advantage that the milk is not concentrated, even if the mother has a high antidiuretic hormone concentration to enable her to concentrate the urine. Since ruminants are prey, they need to drink rapidly when they get access to water. The forestomach allows the animals to store water in the reticulorumen. There is no danger of water intoxication even if they drink to satisfaction in a couple of minutes after having lost as much as 30% of their body weight.

“…Water restriction had no effect on feed intake in the study of Mengistu et al (2004) and suggesting that ruminants are able to accumulate water in reserve to be used in periods of reduced water supply. Water deprivation induces a decrease in body fluid content and an increase in its osmolality.…”

Water consumption, performance, and health in calves: a review

The aim of this review is to summarize the current knowledge of drinking water for dairy calves. Calves receive water from milk or milk replacer (MR), from other feeds, and from free water. Water consumption to weaning is almost low. Opposing opinions are at the beginning of offering drinking water to calves. Some authors recommend providing water from the first day, some since the transition to artificial milk nutrition, or offering after weaning only. The water needed by pre-weaned dairy calves depends on the amount of milk or MR intake. The increased water in MR reduces the need for additional water to be fed as free water. Generally, when calves were fed supplemental water in addition to that provided in MR, they consumed more concentrate mixture and dry matter (DM) as compared with calves not given supplemental water. Water restriction can intensify the stress during heat temperatures period. However, according to recent research, restricting water intake (WI) during milk feeding period did not affect calf feed intake, growth, and health condition. Calves may be able to accumulate water in reserve to be used in periods of reduced water supply. However, we cannot recommend the WI just as part of the MR. We suggest that the water provided by the MR may not be sufficient to satisfy the needs of the animal. Drinking water has to be always at the disposal. Providing ad libitum intake of drinking water is the best approach. Finally, the exactly calves daily water consumptions are listed in a table.
