Processing Technology of Special Feed (Silkworm Feed)
The special feed processing technology of Wuxi Scientific Research and Design Institute of the Ministry of domestic Trade (Wuxi 214035, Jiangsu Province) includes three parts: industrial processing of artificial feed for silkworm, nutritional formula and breeding. In the aspect of processing, it is the first to create a new technology of dry heat killing and drying of fresh mulberry leaves, adopting technologies such as micro-crushing, mechatronics, addition of feed active substances, anti-corrosion, sterilization, molding and packaging, etc. the technical difficulties of raw materials preservation and drying, crushing, wet body mixing and long-term preservation of silkworm artificial feed were solved, new silkworm artificial feed products were produced on a large scale, and the first complete set of technology of silkworm artificial feed production line with an annual output of 1000t in China was developed. In the formulation study, some new methods were adopted, such as replacing mulberry with grass, changing the composition of molding agent and screening the combination of preservatives, and a low-cost and practical artificial feed formula was designed. In the study of culture, the technical standard of artificial feed was established through the research on the key techniques of feeding mode, sleep treatment, silkworm seat protection, disinfection and disease prevention in each age of silkworm.
The project has high technical content, fills the domestic gap, and the achievement has reached the international advanced level. It won the second prize of scientific and technological progress of the Ministry of domestic Trade in 1996 and the third prize of national scientific and technological progress in 1997. This project has changed the traditional situation of single mulberry leaves, effectively reduced the effects of natural disasters and pesticide pollution on cocoon production, and greatly alleviated the contradiction between planting mulberry fields and competing for land for grain and vegetables, so that mulberry cultivation and sericulture can be carried out in different places at different times, getting rid of seasonal and regional restrictions, thus industrial and perennial sericulture, and greatly increase cocoon production. To significantly improve the labor efficiency of sericulture production is a major technological innovation in sericulture. At present, the achievement has been popularized and applied in Jiangsu and other rural areas, and is very popular.

Foxes and raccoons often get sick during pregnancy and childbirth.
From the estrus mating in spring to now, raccoon raccoons have entered the critical stage of pregnancy and giving birth, and their physiological functions have undergone a series of changes and are extremely sensitive to external stimuli, so the incidence rate is extremely high. Recently, many readers have consulted about this. In this regard, the editor specially invited Professor Hua Shufang of the Special products Research Institute of the Chinese Academy of Agricultural Sciences to introduce the prevention and treatment of common diseases during pregnancy and lactation of foxes and raccoons. 1. What are the manifestations of gastroenteritis during pregnancy and childbirth, and how to prevent and cure them? Answer: foxes and raccoons during pregnancy and childbirth

Diagnosis of Candida albicans infection in deer
As a conditional pathogen, Candida albicans (Candidaalbicans) can normally exist in human and animal oral mucosa, gastrointestinal tract, anus, vagina, skin and other parts, generally does not cause disease, but when the body is malnourished, vitamin deficiency, long-term use of antibiotics, the probability of Candida albicans infection increases, serious cases can lead to other organ infections and even death. The single infection of Candida albicans from animals is rare, and it is generally mixed infection, because it is not harmful.
