Treatment of skin diseases of foxes
There are two common skin diseases in foxes, one is acariasis, the other is mycosis. Acariasis can be infected in all parts of the body, in addition to hair removal, the diseased part is grayish white, and there are a lot of dandruff. The diseased fox showed severe pain and itching, the diseased part bled due to gnawing and friction, opened into a thick scab, and the shape of the diseased part was irregular; the itching of fungal infection was slight, and most of the diseased part showed round ringworm spots with clear boundaries, and the scab was backward and bright red and moist. The surface is eroded and often with residual hair. For example, if the diseased materials are collected and treated, they will be examined by microscope.

Estrus and mating of dogs
The estrus and breeding of bitches is an important part of breeding. Only when we correctly grasp the sexual periodic changes and ovulation period of bitches, can we achieve timely breeding and improve the pregnancy rate and fecundity. The main results are as follows: 1. in terms of reproduction, according to the different sexual physiological changes of the dog, the sexual cycle of the dog is divided into four stages: proestrus, estrus, late estrus and anestrus. 1.

Snake feeding and feeding method
When there is time and the environment and season for raising snakes, we think that with the exception of snakes that eat during the day (such as black snakes, etc.), it is better to feed them before sunset or in the evening. Because the activity and foraging of snakes depend on the external temperature, snakes rarely come out of their nests when the temperature is high during the day. Under the condition of breeding, it is common for snakes and cool night to come out and look for food, and crawl back to the nest in the early morning of the next day. There are two other advantages of feeding snakes in the evening, that is, concentrated dead food. Because the temperature is not too high, that is, if there is any surplus, you can still pick it up.

Characteristics of silkworm disease control
(1) A wide range of sources of infection. 1. The source of infection in the process of sericulture: dead silkworm, pupa, moth and their diseased silkworm feces, silkworm sand, old silkworm and rotten cocoon are serious sources of infection of sericulture. 2. Cross-infection with wild insects, mulberry leaves contaminated by diseased field insects, insect carcasses and insect droppings are another source of infection of silkworm disease. 3. Pathogen accumulation and poison pollution in sericulture environment. (2) due to poor feeding and management, silkworms are physically weak and prone to disease. Do not attach importance to

The dog's "fear of hands"
When dealing with dogs, the trainer tries to play only a friendly and commanding role. And never give the dog any threat and intimidation impression. Now let's talk about the dog's "phobia." This "hand phobia" in dogs is caused by improper hand movements of the trainer, which give the dog the impression of danger and fear in daily training. So much so that every gesture of the trainer, whether given to him or intended to show affection, alarmed the dog, and some dogs even began to panic at the sight of the trainer's or anyone else's gesture.

Sex chromosome difference and Origin of Snake
The sex of the snake is determined by the sex chromosome and belongs to the ZZ/ZW mechanism. In order to study the origin and evolution of snake sex chromosomes, KazumiMatsubara, a researcher at the Creative Scientific Research Institute (CreativeResearch.InitiativeSousei,CRIS) of Hokkaido University in Japan, identified Japanese four-stripedrat snake (Elaphequadrivirg) by fluorescence in situ hybridization (fish).

Prevention and treatment of selenium deficiency in raccoon dogs
The prevention and treatment of selenium deficiency in raccoon dogs has obvious regional characteristics. Generally speaking, the geological environment of selenium deficiency causes selenium deficiency in human beings and animals, especially in the years with more autumn rain, the selenium in the surface soil is lost with Rain Water, mainly herbivores or omnivores, it is difficult to obtain enough selenium from plants, which leads to selenium deficiency. The narrow areas from northeast to southwest of China are selenium-deficient areas, especially in the western part of Heilongjiang Province and Liangshan in Sichuan Province. The concentration of selenium in organs and tissues of selenium deficient animals decreased.

The oestrus Law of female Fox
The estrus of the female fox shows that the vulva is covered by pubic hair during the resting period, which is not easy to find; during estrus, the pubic hair is separated due to vaginal swelling. The estrus period of female fox is short, mating is difficult, and the timing of adaptation is also difficult to grasp, especially the empty rate of silver-black fox is higher. In order to improve the reproduction rate, it is necessary to master the oestrus law of female foxes and carry out mating or artificial insemination at the right time. The estrus of female foxes can be divided into three stages: the first stage: the clitoris begins to swell, clitoris enlarges, tends to be heterosexual and sexually excited, and generally continues.

Techniques of disinfection and disease prevention in silkworm rearing
With the large-scale development of the western region, the state began to implement the plan of "moving mulberry from the east to the west". In the new round of industrial structure adjustment, many places in Yunnan Province have focused on supporting sericulture as a characteristic industry to increase farmers' income and become rich. However, in the process of sericulture, the outbreak of silkworm disease is caused by lax disinfection or improper methods, which often leads to no cocoon harvest and heavy economic losses. Thorough disinfection and prevention of disease and putting an end to pathogen transmission are the key measures to seize the high quality and high yield of silkworm cocoons. 1. Disinfection of sericulture officials

"Nine look" discerning Rabbit
The discovery of diseased rabbits and the diagnosis of rabbit diseases are the basis for controlling the epidemic of the disease. the health of rabbits should be observed from the following aspects: healthy rabbits are energetic, smooth, flexible, correct posture and rapid development. On the other hand, most of the diseased rabbits are depressed or extremely excited (such as rabbit plague), rough coat (such as chronic consumptive disease, nutritional deficiency, etc.), slow movement and abnormal posture, such as foot dermatitis and tinea pedis when the hindlimbs dare not touch the ground, "eight-shaped" legs and "O" legs can not stand normally, and it is difficult to breathe when suffering from pneumonia.
