Although water is not a nutrient, it is essential to the life activities of rabbits. Practice and experiments have proved that lack of drinking water can seriously affect the production efficiency of rabbits. If the female rabbit lacks water during childbirth, female rabbits will be able to eat residual litter; lactation water shortage will reduce milk secretion; summer water shortage prone to heat stroke; when the water shortage, especially diarrhea, prone to dehydration and death. Therefore, attention should be given to feeding rabbits sufficient drinking water during the feeding process. According to tests, the water requirement of rabbits is generally 1.5-2.5 times the dry matter intake, and the water requirement for each rabbit per kilogram of body weight per day is 100-120 ml.
