Farmers raise animals, most of them do not care about the cost of drinking water, but only emphasize drinking enough to fully supply. However, with the increasingly tense freshwater resources on the earth today, farmers who are big users of water should also establish “awareness of water conservation†to meet the requirements of the times. Water is very important for farmed animals. In addition to the combined effects of water shortages that can affect the health of animals and deaths that can occur in severe cases, the lack of water in laying hens results in a reduction in egg production, the lack of water in pigs grows slowly, and the lack of water in dairy cows reduces milk production. Therefore, in order to ensure the normal health of the farm animals and normal production performance, but also to achieve the purpose of water conservation, according to the "best drinking water" supply of animal drinking water, is the best way. However, there are only a few animals whose "best water consumption" has available data for reference. The "best amount of drinking water" for most animals is still blank, and it is necessary for the majority of animal husbandry operators to sum up while practicing and to be filled. 1, the chicken's best drinking water. (1) Age-increasing: 1 to 6 weeks old chicks, 20 to 100 milliliters per day for chickens; 7 to 12 weeks old young chickens, 100 to 200 milliliters per day for chickens; 200 to 230 milliliters for non-laying hens; Egg hens 230 to 300 ml. (2) Ratio of drinking water to feed intake: In normal (20°C) air temperature, drinking water is twice the intake; in high temperature (35°C) environment, drinking water is 5 times of feed intake. (3) The amount of drinking water increases with the increase of egg production rate: When the egg production rate is 50%, the water requirement for laying hens is 170 ml per day for chickens; for each additional 10% increase, the drinking water volume increases by 12 ml. (4) Seasonal changes in the amount of drinking water: 100 ml of water per bird per day in winter, 200 ml per chicken in spring and autumn, and 300 ml per chicken per day in summer. 2. The optimal drinking water for beef cattle: For each feed intake of 1 kg feed, in the temperature environment of -17 to 10°C, 3.5 kg of drinking water is required; at 10 to 15°C, 3.6 kg; at 15 to 21°C, 4.1. Kilograms; 4.7kg at 21-27°C; 5.5kg water at 27°C. 3, the sheep's best drinking water: In the same temperature environment, the sheep's drinking water 40% less than cattle. According to the relevant information, sheep consume between 2.0 and 3.0 kg of water per kilogram of feed at temperatures ranging from -17 to 27°C. 4, the best drinking water of the pig, (1) the ratio of drinking water and feeding: slightly less than the sheep, that is, each feed intake of 1 kilogram of feed requires drinking water 2.0 to 2.5 kg. (2) The amount of drinking water varies according to the amount of potassium in the feed: when the feed contains 8 grams of potassium per kilogram, the ratio of feed intake to drinking water is 1:2.9 to 3.3; when the feed contains 9 to 14 grams of potassium per kilogram of feed, The ratio of food intake to drinking water is 1:3.4 to 4.0.
