Parasitic Equorum disease is caused by Parasitic Equorum of horse in the small intestine of horses. It is a kind of nematode disease commonly found in equids and it is very harmful to calves.
Parasitic Equorum are large in size, with an approximately cylindrical body, yellowish-white, males with a length of 150-180mm and curled tails; females are 180-370mm long with straight tails.
The developmental history of Parasitic Equorum is very complicated. After the horse has eaten infectious larvae, it takes a very long time in the body (2-2.5 months) and very complex transitions (with blood circulation through the liver, lungs, and back to the small intestine) can develop into adulthood.
Eggs are extremely resistant to adverse environmental conditions. At a temperature of 39°C, the eggs variably died; at temperatures below 10°C, the eggs ceased to thrive, but they remained viable for a longer period of time, and in the event of suitable temperature conditions, they continued to develop into infective eggs. Therefore, the presence of Ascaris eggs in winter homes is the source of infection in early spring. Drying is detrimental to the survival of eggs.
(1) Mechanical loss. Adults parasitizing the small intestine can cause catarrhal enteritis and intestinal bleeding, and severe intestinal obstruction can occur, and even intestinal spasm and intestinal perforation. Sometimes the body drills into the bile duct or pancreatic duct and causes a corresponding condition (such as bile duct blockage, etc.).
(2) When larvae migrate, they can cause liver cell degeneration and pulmonary hemorrhage and inflammation. At the same time can bring other pathogenic microorganisms, causing secondary infection.
(3) Toxin effect. The metabolites of parasite maggots and other toxic substances act on the mucous membranes. It can cause inflammation and lead to digestive disorders; toxic substances that are absorbed can have serious effects on the nervous system and hematopoietic function.
The locust eggs can be diagnosed by floating with saturated saline. After death, a large number of parasites can be found in the small intestine.
(1) Albendazole, taken orally, once in an amount, 5 mg per 1 kg body weight.
(2) Thibendazole, taken orally, in one dose, 50-100 mg per 1 kg body weight.
(3) Fenbendazole, taken orally, in one dose, 5-7.5 mg per 1 kg body weight.
(4) Mebendazole, taken orally, once in an amount of 8-9 mg per 1 kg body weight.
(1) Deworming regularly. 1-2 times a year, do not grazing within 3-5 days after deworming in order to disinfect the discharged parasites and eggs. Pregnant horses are dewormed 2 months before birth. Found sick, immediately deworming.
(2) Strengthen feed management. Feces are cleared in time and bioheat treated. Disinfect equipment on a regular basis; drinking water is best to use tap water or well water.
