What kind of dog is suitable for family breeding?
Female dogs are suitable for general families. One of the reasons why female dogs are accepted by families is that most of them are mongrel dogs. In order to produce dogs with good pedigree in order to improve the level of raising dogs, dog families are willing to raise a lot of bitches; second, because when bitches give birth to puppies, dog owners can experience the joy of new life. In other words, it can achieve the goal of purifying the breed and improving the physique of the dog by raising female dogs. Most dog owners hope to raise a good breed of dog and breed an excellent next generation.

What should be paid attention to when injecting sick snakes?
Practice has proved that injecting sick snakes is the best way to cure snake disease, but we must pay attention to the following points. (1) many first-time snake breeders who avoid tailing are affected by people getting sick and choosing their buttocks. They think that the best place to inject the snake should be in the tail, but they do not realize that the tail nerve is densely spread, and if there is a little carelessness, it will cause caudal nerve damage and cause discomfort of the sick snake. serious cases lead to death. Therefore, when giving injections to sick snakes, you should choose the muscle plump places below the heart and on both sides of the back. (2) do not use thick needles to inject sick snakes

Why do dogs like to bury things?
The dog in the yard often likes to dig a hole and lie down on a hot day in summer, and it likes to hide in the pit if there is leftover food. Here, because the dog used to dig a hole about 3 meters wide on the hilly slope in the wild, its hoarding habit was also developed at that time. In order to keep the pit for sleeping clean, they will choose another place to defecate. Animals generally have a special habit, and different animals have different habits. Some animals store some food in advance to prevent them from running out of food.

If the temperature of the snake farm is too high in summer, what harm will it do to the snake?
Artificial breeding snakes, whether it is house breeding or snake farm breeding, the breeding density is generally relatively large. In snake breeding places in midsummer, if the temperature is too high or the phenomena of high temperature, high humidity and lack of ventilation are easy to occur before and after the rainstorm, the snakes will not eat, do not move and do not shed their skin; some even take a negative way to protect the heat and enter "summer hibernation". This is bound to affect its normal growth and development. Because the snake itself does not have sweat glands, it cannot adjust its own temperature and humidity. When the temperature on the spot is close to 30 ℃, the amount of water the snake drinks will increase.

Can dogs spread many diseases to people?
It is true that dogs can spread some diseases, but they need certain conditions for transmission. As long as dogs are kept healthy, dogs will not be infected with these diseases and people will not be infected. Generally speaking, families in big cities have the conditions to do so. Feeding dog food, not feeding raw or contaminated food, vaccinating dogs according to regulations, giving regular medical check-ups to dogs, and paying attention to daily hygiene and washing hands after contact with animal excrement, the possibility of human being infected by dogs is extremely small. Although dogs also have viral hepatitis, the virus is completely different from that of humans.

Medicinal use and processing of snake whip
A snake whip is the reproductive organ of a male snake. A complete pair of snake whips consists of two gonadal testicles and two copulators, which contain testosterone, protein and other ingredients. In traditional Chinese medicine, there is a theory of "tonifying viscera with viscera and seeking the same gas phase". According to the determination of relevant scientific research departments, the kidney tonifying substance contained in snake whip is 10% higher than that of deer whip and more than 30% higher than that of seal kidney and dog kidney. Snake whip has the function of tonifying kidney and invigorating yang, warming internal organs, and can treat impotence, kidney deficiency, tinnitus, chronic orchitis, women's uterine cold infertility and so on.

Management of young ducks (31-20 days old)
The management goal of young ducks is to cultivate strong and good physique. 1. To step up exercise, we should drive the ducks to walk slowly around the playground every day, or go outside to slowly drive grazing to strengthen their physique. People should get in touch with ducks more and improve their courage, so that they will not be afraid of shock when they enter the laying period. two。 The feeding of young ducks is a skeletal muscle stage, and the principle of nutrition in the breeding stage is that it should be low rather than high, and the principle of feed is that it should be coarse rather than fine. Fine material

Technical points of checking whether pigs are healthy or not
At present, pig production in China is still dominated by free-range farming. However, due to the lack of scientific knowledge and concept of pig raising, the scientific and technological content of pig breeding, feed preparation, feeding management and disease prevention in production and operation is very low. There have been some problems in pig production, such as slow weight gain, low feed utilization rate, low management efficiency and even loss. Breeders and veterinary technicians should inspect and observe the health status of pigs every day and deal with problems in a timely manner. In order to check the health of pigs, it is generally necessary to master the following skills.

Treatment of a case of bovine actinomycetes
Actinomycosis is a chronic infectious disease of cattle, pigs and horses, of which cattle is the most common. The main pathogens of the disease are bovine actinomycetes (Actinomycesbovis) and Lin's actinomycetes (Acti-nobacillusLignieresi). Staphylococci sometimes participate in the pathogenesis. Bovine actinomycetes mainly invade hard tissue, which is Gram-positive bacteria, the bacterial mass is large, the end of the bacteria line is dilated, showing a radial arrangement; Lin's actinomycetes mainly invade soft tissue, it is Gram-negative bacilli, the bacterial mass is very small, and the radial arrangement is not obvious.

Raise chickens carefully in autumn
Autumn is the first production stage of raising chickens in spring, and the flock management in this period is related to the economic benefits of chicken farms (households). Therefore, the following management measures should be taken for the hens to start laying: changing the transition material in time generally changes the egg feed to the 20-week-old hen, also known as the transition material, with 1% calcium and 16.5% crude protein. When refueling, the application of half a month to gradually complete the refueling process, do not be too hasty, in order to prevent diarrhea. When the laying rate reaches 2%-3.5%, the feed should contain 3.4%-3.5% calcium and 18% crude protein.

Cultivation Technology of Coprinus comatus
1. The production of bacterial rods for clinker cultivation is the same as that of cultivated species. Put the cultivated bacteria bag into the border horizontally or vertically after removing the bag, the interval between the bacteria rods is 2mur3cm, fill it with fertile soil, discharge 30 bacteria sticks per square meter, after discharge, cover the soil for about 3cm. If the soil is too dry, spray water slightly and cover it with polyethylene plastic film that has been soaked in 5% Lysol solution. Researchers in Jiangsu Province have done comparative experiments on horizontal or vertical arrangement of bacterial sticks, which shows that vertical arrangement of mushrooms is faster and has higher biological efficiency.
