Disease prevention and treatment of farmed muskrat

1. Pasteurellosis

1 symptoms: pasteurellosis was mainly induced by drinking water, feed or exogenous infection. The diseased rats showed refusing to eat, being dishevelled, breathing faster and more difficult, a few of them were paralyzed in the hindlimb, muscle spasm and contraction, and had a sudden onset, often those with good physique had more morbidity and no diarrhea, but some anus and urine pores bled, mostly died in the pool, a few died in the cage.

2 Prevention and treatment: ofloxacin can be injected into ①. Strictly control the dose for intramuscular injection, generally, each mouse is injected with 0.2-0.3 ml, twice a day for 2-3 days. ② was injected intramuscularly with cephalosporin 0.15ml per mouse for 3 days. ③ was fed with enrofloxacin, Basik powder or norfloxacin (crushed) into the concentrate for 2 to 3 days according to the prescribed dosage. If enrofloxacin is not available for the time being, you can use paracetamol powder or ciprofloxacin mixed into the concentrate and feed it once every morning and evening for 2-3 days. ④ feed fresh feed, analyze whether the concentrate feed has the possibility of exogenous pollution, do not use the original unfinished concentrate feed, replace the fresh feed, and then mix and feed after high temperature sterilization (waiting to cool). ⑤ strictly disinfects tools, utensils, cages and floors. Disinfectants can be used for sur, bleach, potassium permanganate, lime milk, powerful fungicides, and increase air convection in the field to ensure clean drinking water.

Paratyphoid (salmonellosis)

1 symptom: it has obvious seasonality, especially from June to August. The main symptoms of the disease are fever, dysentery, stench of feces, postmortem splenomegaly of 5 to 8 times, the spleen is dark red.

2 Prevention and treatment: ① analyzes the source of water, removes the suspicious feed that has not been eaten, and ensures the supply of feed with comprehensive nutrition and palatability. ② for patients with serious illness, first use penicillin 0.2ml intramuscular injection, can also take dysentery or chloramphenicol, tetracycline, chloramphenicol, etc. (crushed and infused with water). The whole flock muskrats were fed with one of the above drugs in the concentrate by ③ for 3 days. The diseased rats were isolated by ④ and treated alone.

III. Coccidiosis

Once the disease breaks out, it will also bring losses, so coccidia should be killed four times a year. In particular, after the breeder mouse arrives at the scene, it will kill coccidia once, and then 4 times a year. Can be used gram ball powder, chlorobenzene guanidine, Baota sugar, proprietary Chinese medicine "coccidia king", etc., according to the instructions to mix into the concentrate feed. Intestinal parasites include not only coccidia, but also parasites that cannot even be called experts in professional laboratory departments. Therefore, it is particularly important to eliminate all kinds of intestinal parasites.
