How to prevent and control swine lungworm disease? Prevention and control methods every pig farmer must read
Swine lungworm disease is a helminthic disease caused by Metastrongylus nematodes parasitizing the bronchi and bronchioles of pigs. It is highly harmful to pigs, often causing bronchitis and even pneumonia, and is prone to complicating with pulmonary infectious diseases such as swine pasteurellosis and swine enzootic pneumonia. It often occurs as an endemic disease, mostly infecting pigs when they eat earthworms containing infective larvae. One month after infection, piglets mainly develop coughing, especially obvious when exercising in the morning and evening or when encountering changes in external temperature. Sometimes purulent mucus flows from the nostrils, and there are eye secretions. The appetite of sick pigs is generally normal, but growth and development stagnate, and they gradually become emaciated.

Processing Methods and Technical Key Points of Golden Thread Candied Jujubes
The jujube is a fruit cultivated relatively early in China, and it has high nutritional value. Golden thread candied jujube is a traditional product among Beijing-style preserved fruits, named for the many thread-like stripes on the product. The processing technique is as follows: 1. Material selection: choose varieties with large fruit shape, small pits and thin skin. 2. Scoring: after grading, wash the fresh jujubes with clean water, drain them, and use a needle row or a scoring knife, or machinery, to score 50-100 longitudinal cuts on the fresh jujubes (depending on the size of the jujube fruit), with a depth not exceeding half of the fruit. The score spacing

What are the key measures for duck disease prevention and control? A must-read for duck farmers
I. Do a good job of environmental disinfection 1. Ensure the disinfection effect. Currently, the drugs used for environmental disinfection on farms include: aldehydes (formaldehyde, glutaraldehyde), alkalis (such as caustic soda, quicklime), halogens (chlorine preparations include bleaching powder, Xiaoduwang, Mieduwei, etc., and iodine preparations include iodine trioxide), peroxides (such as peracetic acid), and quaternary ammonium salts (such as Baidusha). Before disinfection, physical cleaning and washing must first be done to prevent the presence of organic matter (such as feces, urine, pus and blood, body fluids, etc.), and then the liquid medicine should be sprayed for disinfection.

How to detect suspicious sick rabbits early? A must-read for rabbit keepers
Examine the ear color of a healthy rabbit: pink, with bright eyes. If the ears are red or light purple, it means the rabbit is overheated; placing it in a ventilated hutch to rest a while will relieve it. If the ears are pale and feel cool to the touch, it means the rabbit has drunk too much cold water or has caught a chill; on auscultation there will be a sloshing sound in the abdominal cavity, and placing the sick rabbit on a heated kang to warm its belly will suffice. If a young rabbit's ear tips bend forward or droop slightly, it means its body temperature is high; let it move about freely for a while to help bring the temperature down. If a rabbit's eyeballs look dull, it indicates the air in the hutch is foul, and ventilation should be carried out promptly. A rabbit running clear watery nasal discharge is a precursor of common cold,

What are the key points for winter cultivation of shiitake mushrooms? A must-read for growers
Shiitake mushrooms are crisp and tender in texture, delicious in taste, rich in nutrients, and highly profitable. Among mushroom farmers there is a saying: "Plant shiitake on one mu of idle land, and become a ten-thousand-yuan household that same year." The key points of winter management are briefly introduced as follows: The climate characteristics of late autumn and early winter are low temperatures, large temperature differences between day and night, and humidity that is easy to control. Under normal circumstances, the mycelium grows slowly, fewer mushrooms emerge, and the fruiting bodies also grow slowly. Under such conditions, keeping the mushroom bed warm and preventing the intrusion of cold wind are key factors among the many growth factors, so attention should be paid to weather changes, and coverage and

Detailed Explanation of the Processing Technology of Ready-to-Eat Pickled Pepper Plumfish
Plumfish, also known as plum croaker, belongs to the family Sciaenidae and the genus Sciaena. It is an important species in China's marine fishing, with a large yield and a low price. Therefore, plumfish is generally used together with other low-value fish as a raw material for surimi processing. 1. Auxiliary materials: red chili peppers, Sichuan peppercorns, old ginger, garlic, refined salt, pepper powder, star anise, cinnamon, white granulated sugar, peanut oil, etc. 2. Processing flow: cleaning → descaling, gill removal, gutting → cleaning → soaking → seasoning → precooking → cleaning and cooling

How Does the San Jose Scale Spread? A Full Analysis of Control Measures
I. Distribution and Damage The San Jose scale (Quadraspidiotus perniciosus) in the Korla region mainly damages pear, apple, apricot, peach, hawthorn, grape, and white poplar, among other fruit trees and forest trees. The insects cluster densely on the branches and trunk in the upper canopy and inner part of the crown, with more on smooth-barked areas and the sunny side. Population density is highest on 2- to 5-year-old branch sections, and on 1-year-old branches they mainly gather around the bud bases. The San Jose scale sucks the sap of branches, leaves, and fruit as female adults and nymphs. Young branches and leaves dry up and fall off after being damaged; damaged fruit develops purplish-red

What are the values and uses of the glossy privet tree? Read this article to understand
Landscaping uses: The glossy privet (Ligustrum lucidum) sways in all four seasons, with well-spaced branches, dense foliage and a neat tree shape. It is a commonly used ornamental tree species in gardens, and can be planted alone or in clusters in courtyards, or used as a street tree. Because of its strong adaptability, fast growth and tolerance to pruning, it is also used as a hedge. It generally takes 3 to 4 years to take shape and achieve a screening effect. It is easy to propagate and raise seedlings from seed, and can also serve as a rootstock for grafting and propagating osmanthus, lilac, and the colored-leaf plant golden-leaf privet. Medical uses of glossy privet leaves: The leaves are opposite, leathery, ovate or ovate-lanceolate, 5-14 cm long,

How to carry out tending and management of dawn redwood? Read this article to understand the key points
Tending should be carried out promptly after afforestation. Watering during April and May is the key to ensuring survival. When planting large saplings, special attention must be paid to drought resistance during the hot season. Weed and loosen the soil two to three times each year, with tending from May to June and from August to September having notable results. After 2 years, applying fertilizer once before spring bud break is very necessary. Generally, pruning is not necessary before the stand is established, but after the stand is established, pruning should be moderate. When the tree height is 6 to 10 m, the pruning height is one quarter to one third of the tree height; when the tree height is 10 to 15 m, the pruning height is one third to one half of the tree height.

How can large-scale rabbit farms prevent disease? These new viewpoints are worth reading
Play down treatment, optimize the rabbit herd. Traditional rabbit farming emphasizes treatment over prevention, often turning the rabbit farm into a sanatorium for sick rabbits. To change this situation, some experts have proposed the "five no-treatment" rule for sick rabbits: do not treat rabbits that cannot be cured, do not treat rabbits whose treatment cost is high, do not treat rabbits whose treatment is time-consuming and labor-intensive, do not treat rabbits whose economic value after recovery is not high, and do not treat rabbits that are highly contagious and highly harmful. Practice has proved that after rabbit farms implemented this system, the health status of the rabbit herd improved markedly, virulent infectious diseases were effectively controlled
