Fox prolapse of anus
Prolapse of anus (prolapse of rectum) is often secondary to severe dyspepsia or gastroenteritis diarrhea, and cubs are prone to hair. Due to the acute weight and increased abdominal pressure, a cylindrical curved tube is protruded from the anus after defecation. Due to the clamping of the anal sphincter, the intestine is edema and is prone to injury and bleeding. If it is not treated in time, the mucous membrane will gradually change from red to purple, and the heavy ones will become black and necrotic. When it is found that the prolapse of the anus should be repaired in time, first wash the dirt on the rectum with 0.1% potassium permanganate aqueous solution. If it has edema, use your hands lightly.

The method of collecting snake venom
There are two ways to collect snake venom: "dead mining" and "living mining". "Dead picking" is a special * destructive method to cut off venomous glands from the head of venomous snakes cut off by processing units or to anaesthetize rear trench venomous snakes and sea snakes that produce less poison, and it is only used occasionally in special circumstances. The "live mining" method is generally used in order to eat snake resources for free. The following is a brief introduction to several "live mining" methods. The method of collecting poison by ⑴ electrical stimulation uses weak electrical stimulation tools such as "acupuncture anaesthesia instrument" to stimulate the mouth of snakes with special electrodes.

There are many benefits to sunning ponds in winter
The author recently visited Xingyang rural areas in our province and found that many fishermen friends quickly disinfected the fish pond after selling out the commercial fish, and then put the fish species in proportion. They think that this will enable fish species to adapt to the pond environment early so that they can open their mouths and grow early in spring. In fact, it is better to expose fish ponds, especially aged fish ponds, to butterflies in winter. The aging of fish ponds is aggravated by the accumulation of fertilizer feed residues, fish feces and sediment impurities, which directly affects the aging of fish ponds in the next year.

Fish that can live without water
Fish rely on their gills to breathe the oxygen dissolved in the water, so the fish can't live without the water. Once they leave the water, they will die quickly. Species with large Gill pores usually die faster than those with small Gill pores. However, there are a small number of fish, they can live out of water for a long time, because these fish in addition to the Gill as the main respiratory organ, there are auxiliary respiratory organs to assist breathing, so they can leave the water without dying. As we all know, climbing perch, Douyu, snakehead, moustache catfish and other fish can stay out of the water for a long time without dying.

Live shrimp shipping box
Hokkaido Aquatic Food Company of Japan has developed a fresh-keeping box for transporting live shrimp, which adopts a three-layer structure; the inner layer is a watertight vinyl box (containing water and live shrimp), with Styrofoam as the outer layer, and a space between the two layers with 5cm or so can be used to put crushed ice or chemical refrigerants. Disinfect and inject some oxygen into the sea water in the inner box, put the live shrimp in the water, then cover it tightly and transport it. Use this kind of packing box to transport live shrimp, even if the external temperature is as high as

Five methods of clearing ponds before the release of fish species
Before stocking, the culture pond must be cleared to kill all kinds of ferocious small wild miscellaneous fish, harmful aquatic animals and plants, parasitic eggs and pathogenic bacteria in the pond, so as to create a good environment for the growth of adult fish. The following five methods of clearing ponds are introduced: first, clear ponds with quicklime. When the pond is cleaned by drainage (that is, the pond is cleaned after the water is drained to 5 cm deep), 60,70kg of quicklime is used per mu of pond; when the pond is not drained, 125kg / m of deep water is used (200p).

Prevent the outbreak of hemorrhagic disease of fish in autumn
Fish are easy to get fulminant hemorrhagic disease in autumn. the disease has the advantages of acute onset, rapid transmission, long epidemic time, high mortality and great loss. Once the disease is difficult to control, the disease is easy to repeat, fish farmers should enhance the awareness of prevention to prevent the occurrence of the disease. First, fish species disinfection: fish species must be disinfected with 1%-2% salt water before entering the pond, and the bath time depends on the physique and temperature of the fish. When conditions permit, the fish species can be soaked with fulminant hemorrhagic disease vaccine. Second, timely change of water and increase oxygen: keep the water quality fresh and change water frequently. If

How to get fat for fish, shrimp and crab in autumn
First, change water reasonably and cultivate fertile water. Since May, "bait" and "liquid" have been used to control diseases and insect pests every other month or 20 days. In the transitional period of summer and autumn, more attention should be paid to the regulation of water quality; to prevent the pool water from becoming "turned" or "old", and to maintain the appropriate transparency of fertilizer and water. The transparency of fish ponds is about 25 cm, that of shrimp ponds is 30 to 36 cm, and that of crab ponds is 35 to 40 centimeters. If the transparency of the pond water is less than the normal needs of fish, shrimp and crabs, use quicklime 5 to 7.5 kg per mu in time.

Six effective methods to improve the disease resistance of fish
Under the current feeding conditions, it is impossible to eliminate all pathogens. However, in order to control the occurrence of fish disease, we can start with scientific aquaculture management and maintain the ecological balance of aquaculture water to improve the disease resistance of fish. As long as proper measures are taken, we will get twice the result with half the effort. 1. Reasonable mixed culture can not only increase the yield per unit area, but also play a certain role in the prevention of fish diseases. As the suitable parasites on different species of fish are not exactly the same, some parasites can only be parasitized on certain fish.

What should we pay attention to when giving an injection to a sick tortoise?
Artificial turtles can be treated by taking medicine, injection, rubbing medicine or even medicine bath if they get sick, among which the effect of direct injection into the tortoise is the fastest and the effect is the best. However, the tortoise has a carapace and has more bones and less flesh. Therefore, the following points must be paid attention to when injecting the tortoise, otherwise it is easy to cause harm to the tortoise. 1. Choose the right injection site. The muscles of the legs of the front and rear limbs of the turtle are relatively plump, and the injection is generally done from this point of view. During the injection, the angle of injection should be 45 °with the limb, and the angle is too high to damage the fascia or bone.

Prevention and treatment of soft-shelled turtle mumps
In the process of raising soft-shelled turtles, if the water quality is not good and disinfection is not strict, it is very easy to make soft-shelled turtles suffer from parotitis. Once the disease occurs, it will cause a large number of deaths. The disease is easy to occur in young soft-shelled turtles, if not handled properly, it can lead to the destruction of the whole army, so it is necessary to prevent and cure it seriously. In this paper, the prevention and treatment of branchitis of soft-shelled turtle are introduced. First, the pathogenic soft-shelled turtle is caused by virus and secondary bacterial infection. Second, the activity of the diseased soft-shelled turtle is weakened, often lying on the edge of the pool or on the eating table, the neck is swollen and cannot stretch freely, but the epidermis is not red, the whole body is edema, and the abdominal nail is pale.
