The content of the abomasum is colored dark red. The mucous membrane of the abomasum and the anterior part of the small intestines is inflamed and covered with small hemorrhages, and in some places of the abomasum - bruises.
It is very difficult to make a diagnosis during the lifetime of animals, since the eggs of the haemonchs do not differ from the eggs of many strongylates. An attempt to conduct an allergic diagnosis also does not give reliable results. Sometimes, to clarify the diagnosis, invasive larvae are grown for 4-5 days. In haemonch larvaethere are 16 spindle-shaped intestinal cells and a short, thinned tail end.
The final diagnosis is established posthumously at the autopsy or examination of the carcasses of forcedly killed ruminants and the detection of parasites and characteristic pathological changes (the content of the abomasum is black and red).
An effective anthelmintic for sheep hemonchosis is phenothiazine, which is prescribed at a dose of 0.5 per 1 kg of body weight (for adult sheep - 15.0-20.0, for lambs at the age of one year - 5.0-10.0). It can be used mixed with grain or as an aqueous suspension with emulsifiers (1% gelatin solution, 2.5-3% flour paste). In addition to phenothiazine, a new drug naftamon (0.3 g/kg), as well as an imported anthelmintic thiabendazole (0.075 g/kg) can be prescribed by the group method (with food).
The following preventive measures are of great importance. chemoprophylaxis of hemonchosis and other strongylatoses of sheep by free group feeding them with fractional doses of phenothiazine during the grazing period. Phenothiazine can be administered with feed (grain fodder) mixed with table salt, as well as in the form of briquettes. To obtain a chemoprophylactic effect, a sheep should eat 1.0 daily, and a lamb - 0.5 technical phenothiazine daily.
In the fight against hemonchosis, phenothiazine is widely used for prophylactic purposes against other strongylatoses of sheep in the republics of Central Asia, regions and territories of the North Caucasus and other areas. As a result of regular feeding of fractional doses of phenothiazine to sheep during the pasture period, on many collective farms and state farms of the Kazakh SSR and the Ukrainian SSR, the clinical manifestation of a number of strongylatoses (including hemonchosis) is prevented.
Haemonchosis is a disease of sheep, rarely goats and cattle, which is caused by relatively large blood-sucking nematodes of the genus Haemonchus, which parasitize in the abomasum. The causative agents of hemonchosis. Haemonchus contortus - the most common species in domestic ruminants, H. longistipes was found in camels and sheep. More than 15 species from the genus Haemonchus have been described, which are observed especially rarely.
The formation of the causative agent of hemonchosis proceeds according to buy escitalopram pills. In an egg in the external environment at temperatures not less than 5.5 ° C and not more than 35 ° C, a larva is formed, which immediately hatches from it, molts twice and at the best temperature indicators (17-20 ° C) after 6-8 days becomes invasive. These larvae are resistant to desiccation and freezing, can migrate up the grass and deep into the soil along the roots.
Animals become infected with hemonchosis on pastures by ingesting larvae with grass and water from shallow puddles and ditches. In the body of lexapro online, after 17-20 days, the nematodes become sexually mature. The dynamics of infection is related to the geographical area. Lambs and young animals over a year old often fall ill to the greatest extent at the end of the summer period and in the autumn period.
With stall keeping (during fattening), the infection of sheep with hemonchs quickly decreases. Haemonchosis is a helminthiasis of cattle, sheep and other ruminants caused by nematodes of the genus Haemonchus. The infection causes great economic losses for farmers around the world. Humans, dogs, cats cannot become infected, as they are not suitable as hosts for the pathogen.
