1.Water is the best vector of disease

We know that water can carry many diseases. Including bacteria, viruses, protozoa, roundworms, etc. The drinking water system of poultry is conducive to the reproduction of microorganisms. Because of its slow water speed, high water temperature, and the hiding place of many microorganisms in the waterline. For example, the vitamins we add can promote the reproduction of protozoa.

Biofilms are the source of diseases, and drinking water systems can easily promote the formation of biofilms due to suitable temperature, making them pathogens such as Escherichia coli, Streptococcus, Pseudomonas, etc. Salmonella can survive in the biofilm for several weeks, and the infectious laryngotracheitis vaccine is still viable within 3 weeks. At the same time, biofilm makes it difficult to clean the water line 10 to 1000 times, and can be formed again when the water is not cleaned properly, the water is not kept disinfected, or when drugs or multi-dimensional are added. This is the most challenging problem in drinking water management.

When the water stops disinfecting and the chicken coop is empty, the bacterial content in the drinking water is greatly increased. There is almost no biofilm in the waterline after disinfection with chlorine dioxide. If the disinfection is not continued, the biofilm will form again after 12 to 24 hours. Experiments have proved that if the drinking water is exposed to the air in the chicken house, the number of bacteria in the drinking fountain increases sharply.

2.Waterline cleaning

After the chickens are eliminated, it is best to flush the water line with high pressure to remove sediment, bacteria, sticky substances, etc. Make sure that the water pressure pipe is in normal condition, and prepare a 400 liter water storage tank to mix 2%~3% hydrogen peroxide. In order to see where the disinfectant has reached, you can add dye and fill the water line. Touch the drinking fountain to get the solution into the drinking fountain. The 3% concentration of hydrogen peroxide stays in the water line for 24 to 72 hours. The residence time depends on whether the product concentration is 2% or 3%. If necessary, leave 2% hydrogen peroxide in the water line again for 4-6 hours, and then clean and disinfect the pressure regulator and water pressure pipe. Ensure that the regulator is not in a flushing state, ensure that the water pressure pipe is in working condition, and all parts of the regulator must be cleaned in place.

If the water contains minerals (calcium, magnesium, iron, manganese), use acid to dissolve and remove scale from the water line. If there are many minerals in the water line, the disinfectant stays in the water line for at least 24 hours. Then use a disinfectant such as bleach to flush the acid preparation in the water line. Add 30 ml of hydrogen peroxide per liter of solution. Mix it into drinking water at a ratio of 1:128 for treatment. This is the last step to help prevent the re-formation of biofilms and even prevent the waterer from sticking after cleaning.

3.The influence of PH on water quality

The pH value range is used to detect the pH value. Each change of 1 indicates a 10-fold change, that is, a difference of 1 number in the pH value and a 10-fold difference in pH value. PH<6.5 is corrosive to water. Some people think that keeping the PH value at 3~4 will help the digestion and growth of the chicken body, which is actually wrong. Because PH<5.9 will affect the performance of chickens, but can inhibit and kill bacteria, PH>8 can reduce the effect of chlorination disinfection. The best range of chlorination disinfection is PH value 4~7.

4.Pay close attention to the drinking water system

  • Dosing device review

Check whether the dosage of the dosing device is correct, and check whether the proportion of disinfectant and water is the same as set. 10 liters of water is not enough to evaluate the accuracy of the dosing device, because this is not enough water, at least 20 liters can be used. It is very important to install a water meter, you can check the water flow into the drinking water system every minute, which helps to check the dosing device. In the important drinking stage, the thinner hoses on both sides of the dosing device will obviously affect the water flow. Maintain the regulator in time, because it has a strainer that is prone to biofilm formation and clogging of sticky substances. Remember that the water flow is not the same as the water pressure. When the water pressure is high, the water flow is fast.

  • Check the water flow of the drinking fountain

Check the water flow rate from the drinking fountain to confirm the proper static flow rate. Check the water flow in different places to observe the water consumption of the chickens. If the regulator is used for a long time, it will age and lose its original function (failure). Therefore, when checking the water flow, be sure to check whether the regulator is normal. In addition, you should keep the water pressure tube (with a ball inside) clean and transparent to see where the water pressure is. When the water pressure pipe gets dirty, it is impossible to use the pressure regulating tool.

  •  The effect of water temperature on body weight

90 meat male chicks were used for the experiment, and the water temperature for the first 4 days was kept at 4.4°C, 21.1°C, and 37.8°C, respectively. The water temperature was checked every hour and adjusted to the target temperature. The chicks were weighed at 0, 7, and 14 days of age. The experiment proved that the low water temperature of 4.4℃ has little effect on the body weight, and the body weight of the high water temperature of 37.8℃ is 8% worse than the standard (21.1℃). %~10%, indicating that high water temperature has an impact on body weight.

  • Shock chlorination disinfection

This is a method often used in the disinfection process. Use high-concentration chlorine with a content of 200PPM for disinfection. The pollutants in the waterline cause “shock”, and it is not safe to use the water because the chickens cannot drink it. It takes 12-24 hours of action time, so the drinking water system will not be used. Most water treatment equipment needs to be disinfected. Calcium hypochlorite contains 70% chlorine. The shock chlorine disinfection method can be used only when the following conditions are met: installation of a new well, after maintenance, rainwater flows into the well during rainfall, the total number of bacteria exceeds 10,000/ml, the colony of bacteria exceeds 100/ml, and the number of Escherichia coli exceeds 50. /Ml before use.

5.Investigate and analyze when problems occur

Attention should be paid to the basic elements. Whether there is a backflow prevention device, whether there is a problem with the depth and location of the well, the location and design of the pool or spring, and other comprehensive factors. At the same time, drip water or cotton test pieces are used to sample for bacteria and mineral detection. Check the use time of the drinking water system, whether there are any changes or the working conditions of the drinking water system, how the entire system is cleaned, what products are used for cleaning, and how the processing procedures are all evaluated.
