1. What is the disease of the sheep in the flock that appears to be in circles, movement disorders, and decreased feeding intake? How can it be prevented?
A: It is proved that the sheep in the flock have hydatid, which is a parasitic disease parasitic on the sheep brain or spinal cord, also known as "polycephaly disease", commonly known as "circle disease", mainly neurological symptoms such as circulation and dyskinesia, which can occur all year round, but more often occur in spring.
Diagnostic points
One look (look at characteristic symptoms and nutritional status): In the later stages of the disease, there will be mental malaise and fasting, as well as malnutrition, resulting in symptoms such as vertebrae bulging and muscle redness.
Second pinch (whether the skull is softened): Most sheep will have symptoms of skull softening in the later stages of the disease, and the skull can be determined by pressing the skull to distinguish whether it is softened, thinned or broken skull, combined with clinical neurological symptoms.
Three checks: If the lateral lymph nodes of the throat are missing, comprehensive judgment can also be made by the changes in the submandibular lymph nodes.
Prevention and control measures
(1) Strengthen breeding management: the surrounding of the sheep pen should reduce the breeding of dogs as much as possible, do not feed the sheep with contaminated feed of dogs, and cannot eat with dogs, and sheepdogs should be regularly dewormed every spring and autumn.
(2) Preventive deworming of sheep is carried out regularly every year, generally once in February, July and December.
(3) Treatment can be carried out directly orally or with mixed ingredients using beef and sheep leech net, calculated according to body weight of 0.12g/kg; subcutaneous injection line mite net, calculated by 0.02ml/kg; oral or mixed animal power anti-toxicity + cattle and sheep summer heat elimination + cattle and sheep liver and kidney health; With intramuscular sulfonamides or florfenicol injections.
2. What is the large number of red dots in the cow's stomach? How can it be prevented?
A: This is the front and rear disc suckers in the cow's stomach.
Anterior and posterior cuntiasis is a general term for trematodiasis caused by trematodes parasitized by chizoma parasitism in cattle, sheep and other ruminants of the anterior and posterior disc families. The main host is the rumen of ruminant livestock and the junction of rumen and reticulum. Adults can cause lesions, but more seriously, larvae can even lead to death when parasitizing the stomach, small intestine, bile ducts, and gallbladder. Clinical features are refractory diarrhea, wasting, anemia, subcutaneous edema, and exhaustion.
(1) Regular deworming to eliminate intermediate hosts.
(2) Strengthen comprehensive prevention and control measures such as feeding management and health management, and strengthen the disinfection of barns.
(3) Timely drug treatment:
(1) Thiobidichlorophenol: 40 ~ 50mg / kg body weight, the drug is dissolved with an appropriate amount of alcohol and then added water to fill it, or it can be directly mixed in refined feed to be fed.
(2) Niclosamide: 50 ~ 60mg / kg body weight, put the drug at the base of the tongue and let it swallow.
(3) Beef and sheep leech net press 0.12g/kg, mixed or directly oral, and used again after 21 days; line mite net press 0.02ml/kg subcutaneous injection can be used once. On the 3rd day after the use of anthelmintic drugs, it can be mixed and fed to cattle and sheep fat treasure + gastrointestinal kang for 7-10 days.
