Breeding technology of meat duck

Problems in drug use. Long-term use of chemicals. Many farmers think that the feeding cycle of meat ducks is short, and generally do not do vaccine prevention. No matter whether the meat ducks are sick or not, they always add a lot of chemicals, such as sulfonamides, to the feed or drinking water of the meat ducks. The end result is that meat ducks are resistant to drugs and even poisoned. When the epidemic occurs, the re-use of such veterinary drugs increases the difficulty and cost of treatment. Second, do not pay attention to the compatibility between drugs. Farmers don't understand the interaction between drugs and think that the combination of multiple drugs will increase the curative effect. Farmers generally use sulfonamides in combination with quinolones, which leads to the reduction or failure of the efficacy of quinolones, which not only fails to play a therapeutic role, but also increases the treatment cost. There are many irrational drugs used in clinic, such as erythromycin and sulfonamides, gentamicin and penicillin, kanamycin and quinolones. Third, the dosage is improper. Once the meat ducks get sick, the whole flock of meat ducks often overdoses for a long time. Farmers think that the greater the dosage of drugs, the better the effect, so they increase the dosage of drugs at will, which leads to the damage of internal organs, metabolic disorder and even drug accumulation, residue and even poisoning of meat ducks. Fourth, there is no symptomatic treatment. Meat ducks have diarrhea due to imbalance of minerals and electrolytes caused by unsuitable feed conversion. However, farmers immediately use antibiotics for a long time, which leads to killing or inhibiting the normal intestinal flora, causing the rapid proliferation of pathogenic bacteria, leading to more serious diarrhea and long-term difficulty in curing. Some duck farmers only use antibacterial drugs to treat viral diseases of meat ducks, ignoring symptomatic treatment, adjusting electrolyte balance and supplementing energy. 5. Improper taking method and insufficient course of treatment. Any medicine has a certain way of administration. According to the nature of drugs and the physiological characteristics of ducks, the route of administration is different. Generally speaking, it is best for meat ducks to mix ingredients or drink water, but the dosage should be doubled; It can also be injected in severe cases. Many farmers not only give drugs improperly, but also have the problem of incomplete drug treatment. Medication has a certain course of treatment, and the general medication time is 5-7 days. Some farmers take medicine for 2-3 days, and stop taking it as soon as they see their condition improving, or change to other drugs immediately. The disease recurred because the effective concentration of drugs in the blood was not enough. Six, long-term use of disinfectants. Duck breeders constantly apply disinfectant to spray and disinfect chickens or water when they are vaccinated with live vaccines. This makes the virus (bacteria) in the vaccine unable to fully reproduce in the body, thus affecting the immune effect. Some duck farmers use corrosive disinfectants (such as potassium permanganate) to disinfect the drinking water of ducks for a long time, which causes damage to the digestive tract and respiratory tract mucosa such as mouth, esophagus and nasal cavity. During this period, using duck plague, duck liver and other vaccines for immune prevention, the body can not establish a good immune response, so that immunity fails. At the same time, the disinfectant that is not easy to decompose also kills normal flora after entering the intestine, causing indigestion. Methods of rational drug use First, fully understand veterinary drugs and use drugs scientifically. Strengthen the study and understanding of veterinary drug knowledge, and understand the main components and pharmacological effects of drugs. Give full consideration to the actual situation of meat ducks and choose veterinary drugs with reliable, safe, convenient and cheap curative effect. Oppose drug abuse, especially the long-term use of large doses of antibacterial drugs. The key to the correct medication of meat ducks is the correct diagnosis of diseases. Some diseases of meat ducks are caused by viruses, such as duck plague and duck hepatitis. Some are bacterial infections, such as serositis and colibacillosis. Viral diseases are often treated with drugs such as interferon, serum, yolk antibody and astragalus polysaccharide, while bacterial diseases are treated with highly effective antibacterial drugs. To treat meat ducks with drugs, we should master the principle of combining traditional Chinese and western medicine with antiviral and antibacterial diseases, and we should not blindly give large doses of drugs. Almost all drugs not only have therapeutic effects, but also have adverse reactions. Scientific and rational use of antiviral drugs and antibacterial drugs, according to the dosage of instructions, can not blindly increase the dosage of drugs at will to prevent drug poisoning. If drugs such as electrolytic multivitamins are used in advance before taking medicine, the stress response can be alleviated and the disease resistance of ducks can be improved.
