In recent years, with the continuous advancement of aquaculture technology, advanced aquaculture and production methods have become increasingly widespread in the aquaculture industry, and have reached a high level in variety breeding, feed formulation, and research and development of pharmaceuticals and biological products. In this case, the duck raising industry has a short feeding period, good efficiency, and it is guaranteed in duck breeds, vaccines, medicines, and feeds. At present, the scale of meat duck breeding in China continues to expand, and large-scale duck farms are becoming more and more popular. As a result, the development of meat duck production has accelerated, and higher requirements have been put forward for disease prevention and control. If ducks have insufficient experience, or there are major problems in feeding and management, and disease prevention and treatment is not in place, it may easily lead to an increase in the incidence of meat ducks, which in turn may cause serious economic losses. Therefore, in order to improve the efficiency of breeding ducks and do a good job of disease prevention and control, it is necessary to discuss and summarize the safe use of ducks.

1 Rational choice of drugs for scientific drug use

Under normal circumstances, ducklings are easily affected by factors such as bumpy roads, stress factors, or failure to sterilize the brooding house as required. Prompt administration can effectively prevent disease and enhance ducks through drug action. The immunity of the seedlings is of great importance to the rearing. For example, ducklings have a greater stress on the transportation or breeding environment. When they need to refuel, transfer to groups, or during transportation, or when the climate changes, in order to avoid the onset of disease, they may be appropriately fed with electrolytic multidimensional and antibiotics to be effective. prevention. At the same time, it should be noted that according to the actual situation in the duck breeding process, appropriate drugs should be selected for symptomatic treatment in order to obtain good results. For example, 1 to 1.5 mL of hyperimmune serum should be used for each duckling within 24 hours of introduction, 1 mL/injection after 3 to 5 days of introduction, and inactivated oil adjuvant vaccine for duck contagious serositis to reduce the Incidence of disease; If ducks are found to be infected by bacteria during the breeding process, their resistance will be reduced at this time, and there is a high possibility of secondary viral infections. Antimicrobial and antiviral drugs should be used in time for treatment. Improve efficacy.

Under normal circumstances, duck hepatitis, duck gizzard and other diseases caused by the virus, and E. coli disease, serositis by bacterial infection. The former can be treated with drugs such as interferon, yolk antibody, serum, astragalus polysaccharide, etc., while the latter is usually treated with antibiotics with better effects. In addition, it should be noted that the use of drug therapy should be combined with anti-bacterial and anti-virus, the principle of combining Chinese and Western medicine, can not be excessive or overdose use of drugs. At the same time, try to avoid frequent changes of drugs in the short term during the treatment process. If the drug has no obvious effect after 2 to 3 days, the treatment plan may be changed as appropriate. The first use of antibiotics to treat duck disease should increase the dose, while the use of several different antibacterial drugs can effectively improve the treatment effect, usually 2 to 3 is appropriate. However, when using prophylactic drugs, use one of them. In addition, the use of drug treatment should be in the ingredients or the allocation of water to master the amount, the specific standard is a good duck group can be eaten within 1h. In the process of mixing drugs, it should also pay attention to medicine and material evenly to obtain the desired effect.

2 Ensure that medication plans and methods are scientific and reasonable

In order to ensure the effect of medication, a reasonable medication plan and method should be formulated in light of the actual condition of the duck. It is recommended that medication be administered under the guidance of a veterinarian to avoid blind medication. First of all, it should be made clear that the diseases of meat ducks are caused by viruses or bacterial infections, and their causes are identified, followed by targeted treatment. The use of antibacterial drugs to treat duck disease should ensure that the dose is appropriate, and the interval and duration of treatment is reasonable. In general, the course of treatment should be sufficient, not too short, but it should not deliberately extend the treatment time. If the duck is only a general infectious disease, it can be observed whether the symptoms disappear after 3 to 5 days of continuous medication. If the symptoms disappear, it can be used for 1 to 2 days to consolidate the curative effect and avoid the recurrence of the disease. In addition, it should be noted that if you need to use iodamine drugs for treatment, you can extend the course of treatment to achieve practical results.

3 Strictly sterilize, strengthen immunity, and do a good job of vaccine prevention

During the breeding process, we found that regular disinfection of duck houses is of great significance in preventing and treating duck diseases. Usually, high-efficiency and low-toxicity disinfectants (such as organic chlorine, etc.) should be selected. Currently, disinfectants for duck breeding farms are suitable. Mainly include aldehydes (represented by glutaraldehyde and formaldehyde), halogens (represented by chlorination agents such as disinfection king, bleaching powder and disinfectant), alkalis (represented by lime and caustic soda), and quaternary ammonium salts ( Representatives of 100 toxamate and hydrogen peroxide (represented by peracetic acid). In order to ensure the disinfection effect, a reasonable disinfection procedure should be established at the same time as the choice of drugs. Generally, the duck should be disinfected for 10 to 14 days and the environment should be disinfected after 7 days. It should be noted that when spraying and disinfecting, duck respiratory diseases are more likely to be induced. To reduce the incidence of the disease, pharmaceutical preparations with less irritating effects on the respiratory tract of ducks, such as complexed iodine, or prophylactic administration of the relevant drugs may be used. In addition, vaccine prevention work should also be done to improve disease control.

USB Laser Distance Sensor

JRT usb interface distance sensor board adds a USB port to a Laser Distance Sensor, inexpensive laser distance measurement sensors, allowing customers directly using GBeacon-2.3-Fx.exe software to control the rangefinder sensor. Usb laser distance sensors are the the most popular model devices, it works by measuring the phase of an visible-red laser beam that reflects on the target. Usually, customers would like to choose CH341SER.EXE version to test.
