Agricultural Science

Knowledge Title: Agricultural Science Other Title: agricultural sciences Knowledge Content:  The study of the natural and economic laws of agricultural development. Comprehensive due to a wide range of scientific issues related to the agricultural environment, crop and livestock production, agricultural engineering and agricultural economy. Forestry science and aquatic science are sometimes included in the broader range of agricultural science.  History The formation of modern agricultural science has only a history of more than 100 years, but the process of its occurrence and development has a long history. The formation of ancient knowledge of astronomy, weather, calendar, measurement and so on is actually related to the early practice of agricultural production of mankind, which is the reflection of the exploration results of agricultural production conditions, seasonal turnover and land use methods. Later, from attempts to recognize the progress of the agricultural environment to try to change environmental conditions and agricultural production objects themselves, people promoted the gradual systemization of knowledge of soil farming, fertilization, irrigation and crop variety selection and cultivation, livestock breeding and breeding.……

Infectious diseases in livestock

Knowledge Title: Infectious diseases in livestock Other Title: infectious diseases of domestic animal Knowledge Content:  A class of animal and poultry diseases caused by pathogenic microorganisms. Infectious and endemic, not only can cause a large number of livestock, poultry deaths and loss of livestock products, some zoonotic diseases can also pose a serious threat to human health. With the development of intensive animal husbandkeeping, preventing the incidence of livestock, especially infectious diseases, has become the focus of veterinary work.  Pathogen microorganisms can be divided into three categories, namely bacteria, viruses and fungi, all of which require the use of optical microscopes, or even electron microscopes to see small organisms (with the exception of some fungi). Some disease-causing protozoa in animals, poultry, although also infectious, but because of the single-cell parasite, usually treated as parasitic disease, not included in the scope of infectious diseases.……

Veterinary Medicine

Knowledge Title: Veterinary Medicine Other Title: veterinary science Knowledge Content:  Study the science of preventing and treating diseases in livestock. The health and disease prevention and treatment of livestock, accompanying animals (e.g. dogs, cats, etc.), economic wildlife, experimental animals, ornamental animals, economic insects (e.g. bees, silkworms, etc.) and fish are all in the field of veterinary medicine. However, the research and prevention of fish disease, silkworm disease and bee disease in China are carried out by scientific research institutions of aquatic products, silkworm farming and beekeeping respectively. With the development of medical health, the scope of veterinary medicine has now been expanded to cover zoonotic diseases, public health, environmental protection, human disease models, experimental animals, food production, pharmaceutical industry and other fields, and formed a number of new marginal disciplines, agricultural production and the development of biology and human medicine has played an increasingly important role.……

Fungal diseases in livestock

Knowledge Title: Fungal diseases in livestock Other Title: mycosis of domestic animal Knowledge Content:  A general name for diseases caused by pathogenic fungi in livestock and poultry. World distribution. China also happens often. There are many types of fungi, but fewer than 50 diseases in humans and animals, and more than 10 can cause deadly infections. Fungal diseases fall into the category of infectious diseases. However, fungal poisoning caused by toxins produced by non-pathogenic fungi is not an infectious disease. If some toxic fungi live in feed or forage, the resulting toxic metabolites or toxins can cause acute or chronic poisoning after being eaten by animals, but are not contagious.  Fungal diseases in livestock caused by pathogenic fungi (see veterinary microbiology) can be divided into three categories: (1) dermatological fungal diseases. The lesions occur in the skin and mucous membranes, mostly superficial and limited.……
