How to prevent and treat highly pathogenic porcine reproductive and respiratory syndrome (PRRS)? A detailed explanation of the technical key points
This disease is a severe viral disease of pigs that has emerged in recent years, an acute highly lethal epidemic disease caused by a variant strain of porcine reproductive and respiratory syndrome virus. The virus is extremely contagious. In infected pig farms, the morbidity rate of piglets can reach 100%, the mortality rate can reach more than 50%, and the abortion rate of sows can reach more than 30%. It is also characteristic that growing-finishing pigs can develop the disease and die. 1. Pathogen: The pathogen of this disease is porcine reproductive and respiratory syndrome virus, caused by Lelystad virus. 2. Epidemiology

Detailed Explanation of the Production Process of Lingtou Dancong Tea
The "honey rhyme" of Lingtou Dancong tea is formed during the processing technique, and the main key processes are leaf shaking and roasting; the two are very important for forming and developing the "honey rhyme" characteristics, complementing each other and enhancing each other.

What is deer blood? A detailed introduction to deer blood among deer products
Deer blood is the blood of sika deer and red deer, which are animals of the Cervidae family, and is a precious traditional Chinese medicine. Since ancient times, it has been a treasured product for healing and strengthening the body among the imperial court, royalty, and high officials and nobles, and compound preparations based on it are called immortal elixirs. Deer blood has also spread widely among the common people and is regarded as a top-grade traditional Chinese medicine. As early as the Song Dynasty, there are records that after pricking the blood and drinking deer blood raw, the skin became full and the person had a healthy appetite. In the Ming Dynasty, Li Shizhen made a relatively detailed study of the medical effects of deer blood, recording in the Compendium of Materia Medica that it greatly tonifies deficiency and damage, benefits essence and blood, and resolves smallpox toxin and drug toxin, among others. He also proposed an effective method of taking it: pricking the blood from between the antlers of a deer and drinking it mixed with wine is even better. The Qing imperial family practiced this even more. According to Xu Ke's Qing Bai Lei Chao: when Wenzong was on the throne, his body was often ill, and his face was often yellow. The physicians said deer blood could be drunk, so @#@253@#@ were kept, and blood was ordered to be taken and presented daily. When the Anglo-French allied forces entered the capital, Xianfeng's coughing illness flared up severely, and he ordered deer blood to be taken for his use, but it could not be obtained in time, and so he died. In modern times, animal experiments and clinical studies have proven that deer blood indeed has multiple therapeutic and health-care effects, including beautifying the skin, treating anemia, regulating immunity, delaying aging, improving memory, resisting fatigue, and improving sexual function.

Product Introduction to Kekeling, a New Type of Silkworm Disinfectant
(1) Content Introduction Disinfection and disease prevention are key technical measures for stabilizing silkworm crops and increasing cocoon production. Researching and promoting silkworm disinfectants that are highly effective, low in toxicity, broad-spectrum in sterilization, stable in medicinal properties, non-corrosive, low in cost, and simple and safe to use is a topic that the sericulture industry in all countries attaches importance to. In recent years, various silkworm-producing areas in China have developed and promoted numerous silkworm disinfectants, and many have been restricted in their promotion and application due to reasons such as unstable medicinal properties, strong corrosiveness, and insufficiently broad-spectrum sterilization. The new silkworm disinfectant Kekeling was jointly developed through collaborative research by South China Agricultural University, the Shunde Chemical and Biological Research Institute, and

A Detailed Guide to the Production and Processing Methods of Candied Carambola
Sour-type carambola is not suitable for fresh eating and is a low-priced raw material. After being candied in sugar, it has a unique sweet-and-sour carambola flavor. With proper handling, it is still an excellent sugar-preserved product. (1) Process flow: raw material selection -> cleaning -> cutting -> color protection and hardening -> rinsing -> sugar processing -> drying -> packaging. (2) Key operating points: 1) Raw material handling: carambola at about 80% maturity. After washing, cut lengthwise along the individual ribs into long rib-shaped thick slices, or cut crosswise into 1.5 cm thick slices, then immediately put them into a 3% alum solution, add a trace amount of turmeric powder to make a suitable yellow soaking liquid, so that the carambola slices take on a bright light yellow color.
