Waterline purification in poultry farms

As the saying goes: It is better to be short of food for a day than to be short of a sip of water. However, many farmers always think in the process of raising livestock and poultry that they only need to feed more and better feed to raise livestock and poultry well, and often ignore the problem of drinking water. Adult chickens need to drink about 250 milliliters of water every day. As an important nutrient, water also has other functions and special significance beyond nutrition. Farmers are also aware of the importance of water to the health of chickens, and they do not dare to neglect the supply of drinking water to chickens. However, many farmers easily overlook one problem, that is, the hygiene of drinking water. Farmers and even veterinary workers , have underestimated the importance of water.

For example: the drinking water is not disinfected in time, and the large-scale reproduction of bacteria turns the closed drinking water system into a container for bacteria; the antibiotics, vitamins, electrolytes and other drugs often added to the water line provide nutrients for the bacteria in the biofilm; the original clean Water chickens become a source of pollution when they drink, causing pathogenic bacteria to reproduce in large numbers in the chickens, causing intestinal diseases; Increased internal humidity and damp litter. There are also increasing cases of molds in animals caused by contamination of drinking water, a problem that often results in costly farms.

Drinking water disinfection is to create an environment for livestock and poultry that is not in contact with the source of infection, so that livestock and poultry will not be infected with diseases. Therefore, the only purpose of disinfection is to reduce the number and concentration of various pathogenic microorganisms such as viruses and bacteria in drinking water, reduce or prevent pathogenic microorganisms from invading the animal body, and achieve healthy breeding. Through drinking water disinfection measures, it is like establishing a "big protective net" for each chicken house, reducing the number and concentration of pathogenic microorganisms such as viruses and bacteria in the drinking water range of the farm, and reducing the incidence of disease. Really achieve the purpose of healthy breeding.

Water has a significant impact on the physiological indicators of poultry:

1. If water is cut off for 24 hours, the egg production rate will drop by about 30%, the eggshell will become thinner, and the eggs will become smaller; the growth of broilers will stagnate.

2. If the water is cut off for more than 36 hours, the hens will moult.

3. If water is cut off for 48-60 hours, chickens will have a higher mortality rate.

4. Losing 20% of the water in the chicken body will lead to a large number of chickens dying.

What are the factors that affect water quality?

The biggest and most easily overlooked pollution in our breeding process is the secondary pollution of drinking water. Whether the farm uses surface water, deep well water or tap water, it must pass through water supply towers, water pipelines and drinking fountains before it can be drunk by animals. Ways of secondary pollution of drinking water:

1. Failure to clean and disinfect the water supply tower, water pipes and drinking fountains, resulting in moss and even accumulation of silt in the water tower, resulting in extremely poor water quality.

2. The water tower is not completely closed, the drinking water is in contact with the air, and a large number of bacterial spores in the air multiply rapidly after entering the water body, which will cause the drinking water bacteria to exceed the standard. In the rainy season, it will also be polluted by rainwater.

3. Regularly add drugs, vitamins, vaccines, etc. to drinking water. The sugar carrier becomes an excellent nutrient base for bacteria to multiply and grow, and remains in the waterline, gradually forming a slippery substance, which is commonly referred to as " Biofilm".

Solution: Biofilms are ubiquitous in drinking water systems and attach a wide variety of microorganisms, such as Cryptosporidium, Campylobacter jejuni, Legionella, Giardia, Mycobacteria, Salmonella, Shigella, and viruses distributed in surface water. The existence of these pathogenic microorganisms increases the risk of secondary pollution of animal drinking water.

The formation and harm of biofilm

Biofilm is a complex of microorganisms, microbial secretions, microbial debris, and adsorbed organic matter, and it is also a way for microorganisms such as bacteria to protect themselves. In an environment with biofilm in drinking water pipes, bacteria can reproduce every 30 minutes. Especially after the lights are turned off at night, the water in the water line is in a static state, and this environment is especially suitable for bacteria in the waterlineto reproduce. Calculated according to the bacterial reproduction cycle, if the bacteria content in the water is 100/ml at the beginning, after one night, the number will reach 5 million/ml. In actual production, symptoms such as habitual diarrhea, low feed intake, and loose stools that cannot be cured have a lot to do with water pollution. At the same time, due to the existence of biofilm, the vaccine or medicine is adsorbed or destroyed by organic dirt, so that the vaccine or medicine cannot function normally.

Water is one of the best transmission mediums for pathogenic or harmful microorganisms, and it is so cheap that it is easily overlooked, so what harm will there be if bad drinking water occurs?

• Induce malignant infectious disease

• Reduced feed conversion

• Decreases the effectiveness of medicines

• Formation of mycotoxins leading to sub-health of animals

• Drinking lines or drinking nipples are frequently blocked and water flow is too low

• Diarrhea, feed feces and other intestinal diseases continue all year round and recur!

Microbial growth in drinking water pipelines

Many farmers have such doubts. How can the water line be polluted when water flows in and out of it all day long without contact with the outside world? The water line is an opaque plastic pipe. We cannot see the inside from the outside, so the subjective It is believed that the waterline will not be polluted. It is very simple to know whether the waterline is dirty or not. Open the outlet of the waterline to check the situation inside. We can easily see a layer of black things. Yes, the waterline that has been used for a long time is indeed dirty. polluted. Then the question comes again, why is it inexplicably polluted when there is continuous water flow for washing all day long without contact with the outside world?

In fact, the waterline is not inexplicably polluted. There is always water flowing in the waterline, which forms a closed internal small environment with internal imbalance and stable temperature. This is the hotbed for the survival of microorganisms and bacteria. Over time, microorganisms , Bacteria will gather in large numbers in the waterline and form a biofilm, which is the dark substance we see in the waterline. This biofilm thins the lumen, affects water flow, corrodes pipes, clogs nipples on waterlines, and contaminates drinking water. The precipitation of these organic matter will lead to a large number of bacteria such as Escherichia coli in the water. In the actual production, the diseases such as low feed intake, continuous non-increase of feed, pull of feed, and dry excrement have a lot to do with water pollution. big relationship.

Scale forms in the water pipes, affecting the water flow. Scale and bacteria combine to secrete extracellular polysaccharide polymers, making bacteria adhere to each other in a very delicate way to form a film. There is static electricity in plastic water pipes and it is easy to attract bacteria. The use of vitamins and minerals in drinking water is easy to form other polymers. In addition, farmers often add a large amount of glucose, electrolytes, and vitamins to drinking water, which will cause biofilm to form in the pipeline. This biofilm mostly contains mucus secreted by bacteria. Mucus has a protective effect on bacteria. Many disinfectants have no effect on this kind of mucus, which will cause a large number of bacteria to breed and endanger the body. After a long time, the biofilm will precipitate and adhere to the inner wall of the water line. Excessive accumulation will not only increase the The risk of nipple blockage in the water line(the chickens do not drink enough water, causing casualties.), provides an energy source for the growth of microorganisms and bacteria.

In fact, if the waterline is not cleaned for a long time, it will have a great impact on the health of the chickens. The test of the water sampled from the end of the waterline proves that the E coli content in the water line is several times, or even dozens of times, that in the conventional well water. And we know that Escherichia coli is the culprit that causes the outbreak of colibacillosis in chicken flocks, so we can see how much waterline pollution affects the health of chicken flocks. E. coli disease broke out in many chicken farms, and it has not been cured for a long time, or it has not been purified repeatedly. It is very likely that the problem lies in the water line. At this time, it is necessary to check whether there is a problem with the water line.

How to Strengthen the Management of Drinking Water and Pipeline Disinfection

1. It is necessary to enhance the awareness of drinking water safety in chicken farm management. A successful large-scale chicken farm should formulate and implement a set of practical waterline cleaning and disinfection technical procedures in accordance with the requirements of drinking water sanitation management and the conditions of the farm to effectively disinfect drinking water. Work is a top priority.

2. Thoroughly clean the waterline during the empty house period to remove the residual dirt on the waterline. Choose a cleaning agent with dual functions of anti-virus and cleaning, such as hydrogen peroxide products, acidifiers, etc., and try to use a new generation of cleaning agents and purification technology.

3. Pay attention to the cleaning of the waterline after cleaning. After the waterline is cleaned and disinfected, it is very important to keep the waterline clean. Try not to use the waterline to inject medicine. If you need to wait until the water is finished, use clean water to backwash the waterline in time. During the dosing period, rinse with clean water every day when you get off work, and soak in disinfectant once a week, and you can get good results.

4. Pay attention to the safety of disinfectants. Chicken farms must consider their safety when selecting and using disinfectants. For example, chlorine, iodine preparations and some oxidizing disinfectants are corrosive to a certain extent, and high-concentration residues may be harmful to animals. The normal flora in the body can cause harm; the entry of quaternary ammonium disinfectants into the animal body can also affect the metabolism of the body. Therefore, try to choose some drinking water disinfectants that are safe for people and animals and have no pollution to the environment.

Hydrogen peroxide has a good disinfection effect and is a safe and environmentally friendly disinfectant. The killing effect of hydrogen peroxide on cell viruses is mainly due to its strong oxidizing property. When hydrogen peroxide comes into contact with microorganisms, it can quickly decompose new ecological oxygen, and the new ecological oxygen enters the interior of microorganisms, denatures the relevant enzymes of bacteria, or destroys the accounting structure of viruses, thereby killing bacteria and inactivating viruses . After research, it was found that adding hydrogen peroxide disinfectant to drinking water has a very good effect on controlling the total number of colonies; after soaking and rinsing the water line, adding an appropriate dose of hydrogen peroxide disinfectant for 5 consecutive days, the results showed that adding The number of colonies at the front, middle, and end of the waterline reached the standard on the second day after the addition, and the total number of colonies remained at a very low level during the cut addition period.
