How to treat salmonellosis in goslings: symptoms and remedies for therapy, prevention

Salmonellosis belongs to a group of common infectious diseases that are diagnosed in poultry. This pathology is successfully cured, provided that measures are taken in a timely manner. But without therapy, the disease provokes the death of up to 70% of young animals. In this regard, it is important to know how and how to treat salmonellosis in goslings, as well as ways to prevent infection.

How infection occurs

Salmonellosis develops as a result of infection of the body with salmonella. Infection occurs through:

• litter;
• infected bird or human;
• water.

In some cases, infection is possible by air. The risk group includes young and immunocompromised birds.

The danger of salmonellosis lies in the fact that even after a complete cure, geese remain infectious carriers. Therefore, the therapy of this pathology must be carried out in the entire flock.

Disease symptoms

The nature of the course of the disease directly depends on the state of immunity. The incubation period of the infection, during which there is no pronounced symptomatology of salmonellosis, lasts from 12 to 36 hours. But in some cases, the pathology proceeds superacutely. With this nature of development, goslings die 2-12 hours after infection in the absence of pronounced symptoms of infection. About a day after infection, the following signs of infection are observed:

• loss of appetite;
• general and muscle lethargy;
• increased sleepiness.

After 1.5 days, the following symptoms join the overall clinical picture:

• conjunctivitis with gray discharge;
• shortness of breath;
• lacrimation;
• flow of mucus from the nose;
• diarrhea;
• tilting the head;
• ataxia.

When the organism is affected by salmonella, goslings have a staggering gait. As the pathological process progresses, the activity of the central nervous system is disrupted. In this case, the goslings fall on their side, and the limbs begin to move involuntarily.

Also, salmonellosis often occurs in a subacute form. In this case, a similar clinical picture is observed. But these symptoms come on gradually over several days.

The danger of this disease lies in the fact that in the absence of adequate treatment, Salmonella spreads to the internal organs, causing tissue necrosis in the liver, spleen, lungs and heart.

Diagnosis

Due to the fact that salmonellosis does not have characteristic symptoms (a similar clinical picture is observed with other helminthic invasions), the disease is detected based on the results of a comprehensive examination of the affected bird. The final diagnosis is made after post-mortem and laboratory studies.

Feeding during treatment

The success of the therapy largely depends on the immune status of the infected bird. Therefore, goslings, if salmonellosis is suspected, are transferred to ready-made feeds. During this period it is forbidden to give:

• stale food;
• eggs;
• fermented milk and dairy products;
• cottage cheese.

Also, the bird must be provided with constant access to drink. It is recommended to pre-boil the water, as the supplied liquid may contain salmonella and other parasites.

At the same time as correcting nutrition, it is important to take measures aimed at preventing the spread of the disease. To do this, poultry houses are regularly disinfected and the litter is changed.

How to treat salmonellosis in geese

For salmonellosis, only drug treatment is used. Folk methods in this case are ineffective. In the treatment of the disease are used:

• "Tetracycline" (within 4-6 days);
• "Sulfadimetoksin" (3 days);
• "Oxytetracycline";
• "Trimerazine".

The duration of antibiotic therapy is adjusted based on the results of current treatment. The dosage of the drug is calculated taking into account the age and weight of the affected goslings. Medicines are mainly given while drinking. But some drugs need to be mixed with food. At the end of antibiotic therapy, furan drugs are prescribed for 81 days. This helps to prevent the recurrence of the pathology and the spread of infection to a he althy bird.

Affected goslings must be isolated for the entire period of treatment. If the therapy does not give a positive result, the infected bird is disposed of. However, even with successful treatment for a long period, the affected goslings experience a developmental lag.

Sick geese can be slaughtered for meat after two months from the end of therapy.

Disease prevention

Goslings under 50 days of age are at risk for salmonella infection. Older individuals are also susceptible to infection. But in such a bird, the disease is mostly asymptomatic and does not cause complications.

In order to prevent infection, vaccination of young animals is recommended on the second or third day after hatching. The procedure is repeated two days later. Immunity to salmonella in geese lasts up to three months. At this age, as noted, the parasite is not dangerous for birds. However, females are recommended to be vaccinated again 20-25 days before the start of laying, as intrauterine infection of embryos is possible.

Preventing the development of salmonellosis is difficult. In order to prevent the disease, it is recommended to periodically disinfect the poultry house and regularly examine the livestock to detect infection in the early stages of development.This approach will help prevent the spread of salmonella in poultry.
