Swine necrotic dermatitis requires focused prevention and control in summer and autumn
I had never seen swine necrotic dermatitis before, and thought it was an old disease that might have already disappeared in our area. Unexpectedly, in July last year, it occurred at a small-scale pig farm in our county. The diagnosis and treatment are summarized below to remind farmers to pay attention to the prevention and control of this disease. 1 Disease situation The normal inventory of this pig farm was 70-80 head. Because the pig market was poor at the time, the farm owner brought in more pigs, reaching 100 head. By July, when the pigs reached about 60 kg, it was found that some pigs on the farm had broken skin, itching, and scabs, mainly

Principles of preventive medication for eel diseases and how to use the hanging bag method
Also called the hanging basket method. Bags or baskets containing medicine are hung around the feeding ground (platform) to form a medicated zone, so that when rice field eels enter this zone to feed, pathogens on their body surface are killed. This method has the advantages of using a small amount of medicine, being simple and convenient, being safe, and having few side effects. However, it also has the disadvantage of not completely killing pathogens. It is generally used to prevent diseases.

A Detailed Guide to the Processing Techniques and Uses of the Chinese Honey Locust
I. Harvesting and Processing: In autumn, cut off the thorns, slice and sun-dry them. For large Chinese honey locust pods, harvest the ripe fruit in autumn and sun-dry. II. Uses: Landscaping: The Chinese honey locust has a tall and unusual tree form, with a nearly round crown and dense branches and leaves. In May it blooms with pale greenish-white flowers; the fruit is colored in its early stage and ripens into black pods in autumn.

What are the preservation techniques for shiitake mushrooms? Introduction to commonly used methods
Shiitake mushrooms have a relatively high respiration rate, and in environments with high temperatures and dryness they lose water very easily, causing the fruiting bodies to shrivel; if the ambient humidity is high, they are prone to rot. The preservation and handling methods for fresh shiitake mushrooms are introduced as follows: 1. Low-temperature preservation. When the fruiting bodies are 60% mature, stop watering for 1 day, and harvest on the next morning or before noon. When harvesting, pinch the very bottom of the base of the fruiting body and twist gently to remove it; avoid pulling the stipe so that it breaks or the cap separates from the stipe, or so that substrate is pulled off with it. After harvesting, spread the fresh mushrooms in a single layer in the workroom, light a stove

What are the main causes of sudden death in pigs?
In the process of pig production, many problems often occur. Some problems are fleeting, some occur from time to time, and some emerge one after another. As managers and technicians of a pig farm, one should learn to let go of the "fleeting ones," pay attention to the "recurring ones," and focus on solving the "endless ones." The problem of sudden death in pigs belongs to the "recurring ones," which often puzzles farmers and requires the attention and concern of managers and technicians. There are many cases of sudden death in pigs, and the diseases

Introduction to the greenhouse peach variety Xuelihong
This variety was selected and bred in-house and named Xuelihong. Under open-field cultivation, the maturity period is generally in early to mid-June (Gregorian calendar); under greenhouse cultivation, the maturity period is generally in mid-April. Greenhouse Xuelihong has a round and uniform fruit shape with a flat top, an average single fruit weight of 150 grams and a maximum fruit weight of 350 grams, bright red color, tender creamy white, white flesh, firm and fine texture, good shipping tolerance, strong aroma, sweet taste and abundant juice, soluble solids content of 12-14%, and extremely high marketability. It is known as the early white pagoda, and its price is generally 3-5 times higher than that of nectarines on the market at the same time, comparable to imported high-end fruit. As of now, 95% of peach varieties cultivated under protected conditions in China are nectarines, and Xuelihong greenhouse peach is the first peach variety cultivated under protected conditions in China.

What is the relationship between yellow fat in pork and feed? An analysis of the causes
Yellow fat meat, also known as yellow fat pork, refers to pork carcass fat that is brown or yellow, with internal organs normal and unchanged and no off-odor, and it is generally believed to be caused by feed. Yellow fat meat is different from jaundice meat; jaundice meat is caused by disease, resulting from blocked bile excretion. In jaundice meat, not only is the fat yellow, but the skin, mucous membranes, joint capsule fluid, tissue fluid, vascular intima, serosa, tendons and so on are all yellow, and the internal organs also show pathological changes. Yellow fat meat fades or disappears after hanging for 24 hours, while the yellow color of jaundice meat does not fade. Yellow fat meat is mostly caused by feeding pigs fishmeal, fish liver oil

Detailed Explanation of the Basic Principles for the Use of Fishery Drugs
The use of fishery drugs is based on the basic principle of not harming human health and not damaging the aquatic ecological environment. In the aquaculture process, the prevention and control of diseases and pests in aquatic animals must adhere to the principle of giving priority to prevention, with treatment as a supplement. The use of fishery drugs should strictly follow the regulations of the state and relevant departments, and it is strictly prohibited to produce, sell and use fishery drugs that have not obtained a production license, approval number, or production standard. Actively encourage the research, development, production and use of fishery drugs that are highly effective, fast-acting, long-lasting, and have low toxicity, few side effects and small dosage, and advocate the use of drugs specifically for aquatic products, biological fishery drugs and fishery biological

Detailed Explanation of Key Technical Points for Greenhouse Peach Cultivation and Management
I. Early training, early shaping, early fruiting. Because greenhouse peach trees are planted at high density, in order to obtain relatively high early income, shaping and flower bud development must be completed within one year: vigorously promote growth in the early stage for early shaping, then control growth in the later stage to produce more flowers. When shaping, whether using the slender spindle form or the "Y" form, yield must be given top priority. Not only should pinching be done multiple times under the premise of adequate fertilizer and water supply to promote more secondary and tertiary branches, but permanent fruiting must also be considered, that is, the branches being trained should not be tipped so they maintain a certain
