What diseases are easy to occur in minks in summer? How to prevent and cure? What precautions can be taken?

High pathogenic microorganisms multiply in summer, and the resistance of minks decreases. Therefore, in summer, farmers should pay special attention to prevent mink disease, poisoning and heatstroke. So what diseases are easy to occur in minks in summer? How to prevent and cure? What precautions can be taken?

What diseases are prone to mink in summer (clinical symptoms)

1. Colibacillosis

The sick mink has depressed spirit, loss of appetite, weight loss, persistent diarrhea, yellow, gray or dark gray stool, mixed with mucus, and in severe cases, defecation incontinence. The sick mink has weak hind limbs, unstable standing, late movement disorder, coma and even death.

two。 Salmonellosis

Diseased mink refuses to eat, depressed spirit, elevated body temperature, loose hair without luster, sometimes purulent secretions in the eyes, vomiting, diarrhea, feces are atherosclerotic or watery, often mixed with a large amount of mucus, sometimes with blood. The diseased mink has weak limbs, a high degree of yellow staining of visible mucus, rapid emaciation and death.

3. Pasteurellosis

The sick mink suddenly refuses to eat, drinking more water, dyspnea, dysentery, gray-green sparse stool, often mixed with blood and undigested feed, anemia, emaciation, and often die after spastic attacks.

4. Eperythrozoonosis

In the initial stage, the feces of the diseased mink are dry, with mucus, then thinning, indigestion, severe watery diarrhea, yellow, green or tar-like, yellow urine, gradual weight loss, jaundice, limb weakness, exhaustion and death.

5. Heatstroke

It often occurs at the hottest noon in summer, when the body temperature of the sick mink rises rapidly, the spirit is depressed, the gait swings, vomiting, breathing difficulties, systemic spasms, and finally die in a coma.

6. Poisoning disease

It is mainly divided into food poisoning and drug poisoning.

The main results are as follows: (1) Food poisoning is characterized by sudden onset of food poisoning in the whole group. the faster the intake and the larger the intake of minks, the more acute the disease is, and the more serious the symptoms are. Sick mink eat less or refuse to eat, vomiting, diarrhea, serious death.

(2) the symptoms of drug poisoning are different due to different drugs.

Second, how to prevent and cure

1. Infectious diseases such as colibacillosis, salmonellosis and pasteurellosis

These are bacterial infectious diseases, in different farms, the same pathogen has different sensitivity to the same kind of antibiotics. In other words, the same disease with the same antibiotics in this farm treatment effect is very good, while in another farm treatment effect may not be ideal, or even ineffective. Therefore, after the disease of minks, it is best to take the disease materials of dead minks for bacterial culture, carry out drug sensitivity test, select effective drugs in this field and use them under the guidance of doctors. Dead marten carcasses and their faeces should be buried deeply, and the environment, cages and appliances should be strictly disinfected.

two。 Eperythrozoonosis

Oxytetracycline hydrochloride powder was added to the feed and 40% 50 g oxytetracycline hydrochloride powder was added to each 50kg feed for 10 days.

If the disease is serious, long-acting oxytetracycline injection can be injected intramuscularly and injected according to the instructions. Strictly achieve one mink and one needle.

The addition of astragalus polysaccharides and VC in feed can enhance the resistance of the body.

3. Heatstroke

If you find a heatstroke marten, you should immediately put it in a cool place with good ventilation, cold compress on the head or cold water enema.

4. Poisoning disease

After finding food poisoning, you should immediately stop feeding spoiled food and take glucose or mung bean soup and other detoxification.

III. Prevention and control measures

1. Infectious diseases such as colibacillosis, salmonellosis, pasteurellosis, etc.

Preventive measures are mainly to strengthen feeding management, enhance body resistance, and eliminate pathogens. The specific measures are:

(1) to strictly control the quality of feed, not to feed spoiled feed, to ensure the hygiene of drinking water, to provide feed with high quality, full price, rich nutrition, good palatability, easy digestion and absorption, and adequate supply of protein, vitamins, calcium, phosphorus and minerals. In the case of not wasting feed, satisfy the supply and give as much as you can, so that the mink can recover quickly and the young mink will grow quickly.

(2) Livestock and poultry by-products must be cooked before feeding to prevent infection caused by the intake of livestock and poultry by-products suffering from such diseases.

(3) keep food utensils, utensils and environmental hygiene, disinfect regularly, remove feces in time, and eliminate mosquitoes and flies.

two。 Eperythrozoonosis

The disease is mainly transmitted through blood-sucking insect bites, needle injection and so on. Therefore, to control the disease, we must eliminate blood-sucking insects.

3. Heatstroke

In summer, sunshades should be set up in the farm to prevent direct sunlight; keep enough drinking water, reduce feeding density, strengthen ventilation and, if necessary, cool down by sprinkling water.

4. Poisoning

(1) precautions against food poisoning. Strictly control the quality of feed, do not feed corrupt and deteriorated feed, establish a reasonable feeding system to ensure the quality of drinking water. When it is cool in the morning and evening, if you feed with a bowl, make the food thicker, reduce the food volume and shorten the feeding time. Withdraw the food bowl after 1.5 hours of feeding each time to prevent the disease caused by eating metamorphic feed. It is best to buckle the heavy material on the cage net and feed it.

(2) pesticides should be kept well in the farm, and the use of rodenticide is prohibited.

To sum up, the management of farmers in summer should not be taken lightly, do a good job in daily management, provide a good growth environment for minks, and feed nutritious feed to improve resistance, we will certainly be able to spend the summer safely.
