"Preparing for this autumn" sweeps away the obstacles to winning the championship In autumn, the epidemic prevention and control of the autumn season (1)

As the saying goes, to win in the fall, health is seven points. You can see how critical the health of the pigeons is in autumn racing. However, pigeons have advantages and disadvantages, pigeon disease is prioritized, the doctor's doctor, should be abandoned, symptomatic treatment is fundamental. If the pigeons are the same, it is very easy to lose the big because of the small. We have given a detailed interpretation of the major diseases of the season for fanciers.

Newcastle disease

Newcastle disease is one of the most serious infectious diseases in pigeon racing, and the disease has been introduced from abroad and has not been able to be effectively controlled, causing serious losses to fanciers. According to the etiological definition, the paramyco virus in pigeons is mainly caused by avian paramyxovirus type I and avian paramyxovirus VII.

symptoms

Acute type of pigeons have conjunctivitis, anorexia, digestive stagnation, a small amount of sticky green stools, rapid dehydration, poor spirits, sometimes crooked head or nerve paralysis, about 2-3 days of rapid death, the rate of infection is extremely fast, in recent years, most of the invasion of the local acute type, especially in breeding pigeons.

General symptoms at the beginning of the pigeon has mild conjunctivitis, about 2-3 days to disappear, the pigeon drinks a lot of water, discharge a large amount of water-containing nodular feces, can still eat or fly, but easy to dehydrate. Severe cases turn into neurological symptoms, including crooked head, torticollis, wing paralysis sagging, foot paralysis inability to stand, the course of the disease is about 2-6 weeks, if fully restored, the production of protective antibodies without sequelae. However, if the virus invades the nervous system, wings or foot nerves, it can cause long-term neurological symptoms and paralysis, and the virus often divides the kidneys and causes long-term drainage. Some pigeons present with atypical symptoms, such as neurological symptoms without diarrhea, and caution should be made to differentiate the diagnosis. After the pigeons get sick, the Paramigo virus persists in the digestive tract for up to 3 weeks, in the respiratory tract for up to 4 weeks, in the brain for 5-6 weeks, the sick pigeon will not be excreted in the body 6 weeks after the onset of the disease and infect other pigeons, some of which will cause moulting defects and grow deformed new feathers.

Treatment

At present, the disease is mainly based on early prevention, when the disease occurs, drugs should be found as soon as possible for rapid treatment, mainly to take vaccination and strengthen feeding management, according to the pathogenesis characteristics of Newcastle disease, young pigeons should do a good job in epidemic prevention before the maternal antigen fails.

It is recommended that young pigeons be given nasal drops or eye drops with newcastle disease live pigeon seedlings at 7-10 days old, and injected with new flow gland inactivated seedlings of pigeons at 15-20 days old. Strengthen immunization against neoflora inactivated seedlings on the 40th-45th. Can produce highly effective antibody protection.

Pigeon acne

Pigeon pox is a common infectious disease caused by pox virus infection in the herpes virus. It can be sick in pigeons of all ages. After recovery, it can be immunized for life, so the disease is most common in young pigeons and young birds. Autumn is a time of high incidence of pigeon pox, with the general symptoms being:

Growing on the head, eyes, corners of the mouth, wings, feet and legs, around the anus and other parts of the pigeon, it will affect the diet and weight of the pigeons, and seriously affect the family flight.

According to the different sites of onset, it can be divided into:

1. Skin type

The cutaneous type is the formation of blisters or nodules on the bare skin without feathers, which then breaks down.

2. Mucosal type (diphtheria type)

The mucosal type occurs on the mucous membranes of the mouth, throat, and eyes, and in severe cases, it affects the trachea and esophagus.

3. Hybrid type

Mixed types have symptoms of both cutaneous and diphtheria types.

Once a pigeon pox occurs, one is elimination and the other is healing. Skin type, the nodule is removed, coated with iodoglycerin, iodine wine or potassium permanganate for surface disinfection, soon it will scab and fall off; mucosal is more troublesome, removal is easy to bleed, if not bleeding, a pull will be detached, you can determine not pigeon pox but the foci of trichomoniasis.

Pigeon pox is mainly to prevent, strengthen the management of hygiene, maintain a good sanitary environment, regularly clean and disinfect the loft and utensils, timely clean up the stagnant water, pigeon manure and the breeding density of the loft, which is one of the important measures to prevent pigeon pox.

worm

Helminths are a general term for internal parasites such ascariasis, tapeworm disease and capillary worms. There are 2 types of worms, nematodes with roundworms and capillaries, and a pyridocyctic worm that parasitizes in the pigeon's trachea, mainly tapeworms in flatworms.

The young birds have no resistance to worms and are particularly susceptible. The old birds have a little immunity and do not show symptoms even with insects. These persistent pigeons with worms are a potential source of infection for young birds. Worms can reproduce directly or indirectly. Direct propagation means that after sexual maturity, the eggs that are excreted into the surrounding environment with feces are directly swallowed by the pigeons and infected. Indirect reproduction is when the eggs first enter an intermediate host and develop into larvae in it, where the pigeons eat the host and the larvae grow into mature worms in the pigeons. Helminthiasis does not present symptoms for a long time, but is not asymptomatic.

symptoms:

Anemia, increased drinking water, rapid sales, stunted growth and low energy for young birds. The disease is particularly dangerous for young pigeons, which can lead to the death of young birds, and worms can also eliminate toxins, which is affected by the development of the body.

prophylaxis:

Helminthiasis reduces the reproductive capacity of pigeons, causes nutritional deficiencies, and is complicated by other infectious diseases.

(1) Check the pigeon manure regularly, and treat and disinfect the worms as soon as possible if they are found

(2) Clean the pigeon loft manure every day, southern fanciers should pay attention to the rain and humidity, pigeon manure fermentation is the most likely to breed worms

(3) Worm eggs have a very hard shell, which is still infectious in feces or soil for more than one year, so choose a disinfectant that can penetrate and destroy the shell of the worm

treat:

(1) Roundworms and capillaries need to be dewormed one by one, and the shed is disinfected after deworming

(2) For young or old birds, avoid continuous medication for more than 3 days when deworming

Trichoderma

Trichomonas are mainly parasitic in the mouth, throat, esophagus and sac of pigeons, and are transmitted by feeding and drinking water in pigeons. There is a very scary number about trichomoniasis. 80% of pigeons are infected with trichomoniasis, and unlike pigeon pox, trichomonas are not immune for life because they are cured. Its infection is continuous, and after killing it will come back after a while, and the general drug can maintain about one.

A small number of trichomonas pathogens are not bad for pigeons and can increase resistance to trichomonas, especially for young pigeons, but when the caterpillar pathogen breeds to a certain number, it will become ill, and the incubation period of trichomonas is generally 4-14 days, usually within 7 days. Infected trichomonas generally have no special performance, but when you pick up the pigeons, you will find that there are white spots in the throat and sputum in the mouth, and the most terrible thing is that it happens to meet the race period, affecting the speed, and the results must be greatly reduced; if the breeding pigeons are paired under the trichomonas infection, there is no need to expect to breed an excellent next generation.

There are 3 common types of trichomoniasis:

(1) Oral type

Manifested by increased water intake, decreased food intake, listlessness, closed eyes, severe cases of casey yellow nodules in the mouth, esophagus and sac, pulling green feces, young pigeons born two weeks are most susceptible to infection, and severe cases can block the trachea in a short period of time and die.

(2) Umbilical type

In the nest bowl, the young pigeons have yellow hard lumps around the umbilical cord, the umbilical eye contracts poorly, and the young pigeons are hindered in development and die prematurely.

(3) Visceral type

The young birds have an infection with the umbilical cord entering the body, the pigeon is depressed, the feathers are erect, the appetite is exhausted, and the green will eventually die. Visceral trichomoniasis has a very high mortality rate, and lesions can also be seen in the liver during dissection, and lesions can also be seen in the pericardium and air sac.

Prevention begins with the hygiene of diet, especially drinking water.

(1) Change the water frequently every day, after feeding at night, the kettle should be put away in time, the remaining water should be poured out, cleaned and hung in the ventilation place to drain, and then used the next day. Of course, fanciers with conditions can be equipped with two sets of water bottles for cross-use, which is safer.

(2) Usually pay more attention to the mental state of the pigeon and the color of the pigeon dung, but also often check the mouth of the pigeon, once the mouth is found to have foreign bodies, white spots, sputum filament, it is necessary to treat in time.
