Water is the most important and most important substance in the growth of broilers. The demand for water from broilers is 2 to 2.4 times that of feed. The demand for minerals and trace elements in livestock and poultry is largely derived from water. In the high-density and large-scale farming mode, high-quality drinking water is more decisive for controlling growth than feed and medicine. Livestock and poultry drinking water quality standards Sensory Index. The standard drinking water is colorless, odorless, odorless, non-suspending, clear and transparent, free from impurities, algae, and sediment-free. The required color is no more than 30 degrees, and the turbidity is no more than 20 degrees. If there is debris, it will make the water turbid, breed viruses, bacteria, and produce harmful toxins. It cannot be used for animal feeding and drinking. General chemical indicators. The drinking water quality standard stipulates that the pH of drinking water for broilers is pH 6.5-8.5 and the hardness is not more than 1500 mg/L. If a large amount of alkaline water, can cause alkalosis; if the pH value is lower than 3 to 4, it will cause cell metabolism disorders, and even poisoning. High hardness of calcium and magnesium ions in water concentration is high, can compete with other water-soluble ions, under the influence of temperature, these ions will cause protein coagulation, crystal precipitation. Magnesium carbonate, calcium phosphate, calcium carbonate, sodium carbonate, etc., if the content is too high, it is easy to form crystals and sediments, block water pipes or nipple drinkers, but also reduce the vaccine price, disintegrate disinfectant. Toxicological indicators. Traces of harmful toxicants and impurities in water mainly include fluoride (≤2.0 mg/l, cyanide (≤0.05 mg/l), arsenic (≤0.20 mg/l), cadmium (≤0.01 mg/l), and chromium (≤0.05 Mg/l), lead (≤ 0.10 mg/l), mercury (≤ 0.001 mg/l), and drinking water that exceeds this limit for a long period of time can cause poultry growth arrest or poisoning. Bacteriological indicators. There are many pathogenic microorganisms in the water, such as E. coli, Salmonella, Pasteurella, Bacillus subtilis, parasites and so on. The total coliform population in broiler chicken drinking water should not exceed 100 per litre. Ionic index. Ions in drinking water mainly include calcium, phosphorus, magnesium, iron, zinc, copper, and manganese. Magnesium is a laxative, requiring an index below 125 mg/l; manganese is below 0.05 mg/l; iron is below 0.3 mg/l; copper is below 1 mg/l; and zinc is below 1 mg/l. The change of ion content in drinking water has certain influence on the production performance and health of broilers. For example, large doses of sodium chloride in drinking water can induce broiler's pulmonary hypertension and ascites; the inorganic ions in water, calcium, magnesium and sodium salt form soluble solids. The main ingredient, and its high content, can easily cause harmful effects on the flock. Studies have shown that changes in the concentration of calcium and magnesium ions in drinking water have no significant effect on the growth of broilers (0-3 weeks old), but the feed conversion rate increases with the increase of magnesium ion concentration. Guarantee drinking indicators Water source selection. The establishment of the farm should choose tap water or underground deep well water with good water quality. There should be no pollution source within 50 meters to 100 meters around the water source to ensure water quality safety from the source. Prevent pollution. Do a good job of manure treatment to keep the farm clean. Drinking water disinfection. Disinfection of drinking water is also an important measure to control pollution from the source and prevent the epidemic of intestinal infectious diseases. Drinking water disinfection methods mainly include boiling disinfection and drug disinfection. Boiling disinfection method is simple and reliable, the effect is reliable, raw water boiled for about 5 minutes, the pathogenic microorganisms in the water can kill most of them. If possible, they should try to drink cool boiled water or deep well water, try not to drink surface water. Bleaching disinfection method is a widely used method of drinking water disinfection. Pour 100 liters of water into a water tank and add 1 g of bleaching powder (containing 0.2 g of available chlorine). Stir with a clean bar and use after 30 minutes. If bleaching powder is added to water wells, water towers, and sinks, it can be calculated by adding 1 cu m of water plus 8 g of bleaching powder and disinfecting it for 30 minutes. In addition, potassium permanganate or other disinfectants can also be used for disinfection to ensure water quality. Purification facilities. Increase investment in purification equipment, and purify areas with poor water quality and serious pollution, can increase the efficiency of breeding and reduce the incidence of diseases.
