Helminthiasis, or more simply, damage to the body by parasitic worms, called helminths or worms, is found in humans, animals and even plants. Birds, including agricultural ones, are no exception. The defeat of the body of poultry with worms often leads to a number of negative consequences., and in especially advanced cases, to the death of a bird. One of the most effective means of combating this disease is tetramisole, with instructions for the use of which can be found below.
Symptoms of the presence of worms in birds
Signs the fact that the birds have got worms can serve following symptoms:
- Weight loss, a sharp decrease in body weight.
- Decreased productivity, the softness of the eggshell.
- Inflammatory processes in the small intestine.
- Liquid excrement yellow color.
- Lethargy, apathy, lethargy, lack of appetite.
- Birds such as chickens and turkeys have blanching of the crest.
To eliminate and prevent conditionscaused by the defeat of the body of poultry with worms, the well-proven drug tetramisole, which has a broad anthelmintic effect, is often used.
Indications for the use of tetramisole
Helminthiasis in poultry can manifest itself quite widely, depending on the type of parasite that has settled in the host's body. Worms can parasitize various organs - lungs, gastrointestinal tract, oviducts, mucous membranes. The most common helminths are roundworms, pinworms, tracheal worms, capillaria or nematodes.
Worm larvae are able to penetrate the eggs, which can lead to human infection. You can not also eat the meat of poultry infected with parasites.
Tetramisole is used as an anthelmintic for prophylactic purposes., as well as for the treatment of birds from helminths. Birds housed in clean cages are less susceptible to parasites than poultry with limited walking space. Nevertheless, prophylactically, the drug should be given twice a year, and if necessary, deworming individual individuals additionally.
The drug belongs to relatively safe anthelmintic drugs, possessing moderate toxicity, without causing embryotoxic, teratogenic and mutagenic effects in the recommended dose. After taking the drug orally, tetramisole is rapidly absorbed from the gastrointestinal tract, reaching the maximum concentration in tissues and organs 60 minutes after administration and maintaining the concentration level during the day. The elimination of the drug from the body occurs mostly with urine and to a lesser extent with feces.
Composition and form of release
The drug is produced in the form of granules and powder. Granules of various shapes, ranging in size from 0.2mm to 3mm, of light dirty yellow color, are packed in polyethylene-coated bags or jars with a capacity of 50g, 100g, I50g, 200g, 250g, 500g, I000g and 5000g. By release forms differs tetramisole 10% and 20%, where per 100 g of the drug there are 10 g and 20 g, respectively, of the main active ingredient - tetramisole hydrochloride. Tetramisole powder also has a dosage of 10% and 20%, is a homogeneous powder of gray-white light color. Packing of tetramisole in powder form takes place in cans or bags with various capacities from 50g to 5kg.
Doses and method of administration, instructions
The drug is given once during the morning feeding of the bird. Preliminary preparation for taking tetramisole - the use of laxatives or diet is not required. In the case of using tetramisole to treat individual birds, the medicine diluted with water is poured orally using a syringe-dispenser. With group deworming the drug is thoroughly mixed with compound feed at the rate of 5 g per bird or 50-100 g of feed mixed with medicine. The finished mixture is evenly distributed into the feeders, ensuring free access to food for the entire livestock.
During the treatment of poultry with tetramisole, slaughter should not be carried out earlier than 10 days after taking the drug. Eggs can be used for food after 4 days from the date of deworming.
Side effects
If the dose recommended by the manufacturer is observed, there is a good transfer of tetramisole in domestic birds without any abnormalities. Even an accidental excess of the recommended dose up to 15 times does not have a toxic effect on poultry.
Contraindications
Animals and birds with infectious diseases not associated with helminthic invasion are not subject to deworming until complete recovery. In addition, the agent cannot be used in birds with impaired renal and liver function. Simultaneous administration of tetramisole together with organophosphorus preparations is prohibited, as well as with drugs Pirantel and Morantel.
Success in such a field as poultry farming directly depends on such indicators as the volume and quality of products. It is possible to reach high standards only by cultivating fully healthy animals. The absence of parasitic organisms in poultry is one of the key factors affecting the health of domestic birds.
