Application Methods of Baijiu in Sericulture Production
Baijiu is made by fermenting grain or certain fruits, has a bactericidal effect, and is commonly used as a disinfectant, cleaning agent and preservative. At the same time, it is also a traditional Chinese medicine that can promote blood circulation, lift the spirits and enhance the action of medicines, and is known as the "chief of a hundred medicines." Therefore it is also widely used in sericulture, both preventing disease and increasing yield. 1. Egg surface disinfection. Soak silkworm eggs in 60-proof baijiu, and after about 60-70 seconds immediately remove them, shake off the excess liquid, spread out the silkworm eggs and let them hatch. This allows the ants to emerge earlier, and the ants emerge uniformly, grow robustly and suffer fewer diseases. 2. Mulberry leaf surface

Application Methods of Phytase in Pig and Poultry Diets
Phytic acid or phytate is commonly present in plant feedstuffs, and most of the phosphorus in them exists in the form of phytate phosphorus. Phytic acid can form stable complexes called phytates with metal ions such as calcium, iron, zinc, and copper ions, and can also bind with proteins and starch, reducing the activity of endogenous amylase, protease, and lipase, and significantly lowering the digestibility of various nutrients. Phytic acid is not absorbed by monogastric animals and is mostly excreted in feces, which not only greatly reduces phosphorus utilization but also causes environmental pollution, especially water pollution.

Application of Artificially Hatched Artemia in Industrialized Cultivation of Yellow Catfish Fry
1. Wide-ridge double-row planting method: This method transplants rice seedlings in a sequence of 6 cun, 12 cun, 6 cun. Its advantages: First, the total number of hills per mu (16,000 hills) is slightly less than that of monoculture rice, but yield increases through ventilation and light penetration; Second, it provides more than 7 hours of light daily, raises water temperature, and allows plankton to reproduce and grow rapidly, creating good conditions for providing natural food organisms for yellow catfish; Third, it broadens the activity space for yellow catfish, enables large-scale pest elimination, and fish feces serve as fertilizer, increasing rice yield. 2. Rice management: Rice cultivation management strictly follows

Detailed Explanation of Immune Application Methods for Pig Vaccines
1. Concentrated multivalent inactivated vaccine against Streptococcus suis: Action: prevents septicemia, encephalitis, polyarthritis and abscess disease caused by Streptococcus suis. Usage: boars and sows are injected twice a year, 3 ml per head by intramuscular injection each time; pigs over one month of age are injected 2-3 ml per head intramuscularly each time. 2. Inactivated bivalent vaccine against infectious atrophic rhinitis of swine - toxigenic Pasteurella multocida: Action: prevents atrophic rhinitis and pasteurellosis in pigs. Usage: sows are injected intramuscularly in the neck 1 month before farrowing

Auxiliary Application of Carbon Dioxide and Carbonic Acid in Live Fish Transport
Carbon dioxide-assisted live fish transport is a new technique that keeps live fish in a sleep-like state for extended periods to reduce transport costs. When using carbon dioxide to assist in transporting adult carp, the adult carp must be alternately perfused with carbon dioxide gas at a high partial pressure (27-33KPa) and a low partial pressure (13-17KPa); the transport time can be maintained for about 10 hours, with a very low mortality rate. A mixed gas of carbon dioxide and oxygen (50:50) can also assist in transporting live fish. In this case, gas can be directly injected into the water containing crucian carp and

A Detailed Guide to the Application of Antibiotics in the Treatment of Snake Diseases
Antibiotics, originally called antibacterials, are metabolic products of microorganisms such as bacteria, fungi and actinomycetes. At very low concentrations they can inhibit or kill pathogenic microorganisms and systemic bacterial infections. They are one of the commonly used and indispensable high-efficiency drugs in clinical practice, and are equally applicable to the prevention and treatment of snake diseases. Practice has proven that injecting antibiotics into snake bait can not only prevent snake diseases, but also improve snake metabolism, promote growth, and raise the survival rate or feed conversion rate. Commonly used antibiotics include penicillin, erythromycin, cephalosporin, chlor

What Are the Uses of Snake Venom? A Comprehensive Analysis of Its Main Application Value
1. What Are the Properties of Snake Venom? Snake venom is a toxic protein and polypeptide substance containing various enzymes secreted by venomous snakes, and it is also the substance that causes poisoning reactions after a venomous snake bite. Fresh snake venom is a somewhat fishy-smelling, egg-white-like viscous liquid, appearing yellow, pale yellow, green, or even colorless. When fresh, it shows a neutral or weakly acidic reaction, and after standing for a while it can become alkaline. Its water content is 50%-75%, and its specific gravity is between 1.030 and 1.080. Fresh venom easily forms foam when exposed to air, and at room temperature it is prone to spoilage and deterioration after 24 hours, losing its toxicity.

The function and application method of the automatic mounting-cluster agent for ripe silkworms
(1) Brief introduction "Automatic mounting-cluster agent for ripe silkworms" is a new type of silkworm medicine that promotes uniform maturity of silkworms and automatic mounting of ripe silkworms onto clusters; at the same time, unripe silkworms, diseased silkworms and weak silkworms do not climb onto the clusters, improving cocoon quality and reducing the rate of inferior cocoons. (2) Advanced nature of the technology "Automatic mounting-cluster agent for ripe silkworms" passed appraisal organized by the Guangdong Provincial Higher Education Bureau in 1993, and experts unanimously considered that the result reached the domestic leading level. In China, molting hormone is used to make silkworms mature uniformly; when they are ripe, they are picked up one by one by hand and placed on clusters, or unripe and ripe silkworms are picked up together with both hands and placed on clusters.

B-Mode Ultrasound Diagnostic Methods and Applications in Canine Pregnancy
The application of ultrasound diagnostic technology in the veterinary field began in the mid-1960s, initially using A-mode and D-mode ultrasound. With the development of electronic technology and the electronics industry, it advanced to M-mode and B-mode by the mid-1970s. The B-mode ultrasound diagnostic apparatus, also known as B-ultrasound, uses brightness modulation, reflecting signal intensity through the brightness or darkness of light spots. Because B-ultrasound can perform real-time imaging of the body, display two-dimensional images of the examined area, and clearly show the dynamic changes, morphology and adjacent relationships of internal organs and tissues, as well as the internal echoes and structures of soft tissues, the distribution of blood vessels and other ducts, B-ultrasound is also called a real-time ultrasonic tomographic imaging diagnostic apparatus. Furthermore, because B-ultrasound causes no damage to the body, allows treatment of the examined area under its guidance, and has a wide range of applications, it gained the attention and widespread use of the medical community as soon as it was introduced, and has now become one of the four major medical imaging diagnostic methods. In veterinary and livestock production, B-ultrasound has likewise been widely applied; at present, whether abroad or domestically, whether in basic veterinary theoretical research, livestock production practice, or clinical veterinary application, B-ultrasound plays a very important role, and has been hailed as a revolutionary change in veterinary diagnostic technology, being applied in fields such as pregnancy monitoring, superovulation, disease diagnosis, and selective breeding and fattening monitoring. At present, one of the main uses of B-ultrasound is monitoring the uterus and fetus during animal pregnancy. Combining the author's experience, this article briefly describes the main applications of B-ultrasound in canine pregnancy monitoring.
