How to treat swine winter diarrhea? A detailed explanation of integrated Chinese and Western medicine therapy
Porcine epidemic diarrhea in winter, commonly known as winter diarrhea, has its peak incidence from mid-December each year to mid-January of the following year; it strikes suddenly, spreads over a wide area and spreads rapidly; the incidence rate is high, seriously affecting the growth and development of pigs. 1. Symptoms The incubation period of the disease is generally 12-18 h. After infection, adult pigs show symptoms of watery diarrhea; the feces are initially grayish-white, gradually becoming yellowish-green, with an offensive fishy odor. Abdominal distension, vomiting, body temperature rises to 40-41°C in the initial stage, and once the diarrhea passes, the body temperature drops. Thirst and a desire to drink. 10 days

What role do carbohydrates play for pigs? What pig farmers need to know
Carbohydrates are composed of three elements: carbon, hydrogen and oxygen. They are the main component of plants, accounting for about 70%-80% of all nutrients in plants, and are the main energy source in pig feed. After carbohydrates enter the pig's body, they are transformed into energy through a series of changes, providing heat energy for the pig's various life activities. The carbohydrates remaining after meeting daily energy consumption can be converted into fat in the pig's body and stored as an energy reserve, to be used when hungry. The pig's fat and leaf fat are this reserve of surplus energy. Pigs have a strong ability to convert carbohydrates eaten into fat, and when a large amount of carbohydrates is eaten, body fat increases quickly as well, so feeding pigs with feed rich in carbohydrates (such as corn, rice, sweet potato, potato) makes it easy to convert into body fat. When raising lean-meat pigs, carbohydrates should be supplied reasonably, especially in the late fattening stage, when the feeding amount of such feed should be appropriately reduced to prevent the pig from becoming too fat.

Detailed Explanation of Bag Cultivation Technology for Shaggy Mane (Coprinus comatus) Using Fermented Substrate
I. Cultivation Timing and Spawn Selection (1) According to the actual conditions of each mushroom grower, substrate production is carried out in winter, spring, and autumn respectively. Since shaggy mane has the characteristic of not fruiting without casing soil, spawn bags can be mass-produced during the slack farming season, and casing soil applied 20-30 days in advance according to market demand for fruiting. (2) Select varieties with plump fruiting bodies, moderate individual size, few scales, disease resistance, and high yield. For fresh sales, choose solitary-growing varieties; for salting, choose cluster-growing varieties. II. Substrate Formulas Formula 1: cottonseed hulls 58%, corncob 30%, nitrophosphate-potassium 2%

Key points of seedling protection techniques for newly planted early-sprouting tea: improving the survival rate of tea seedlings
In recent years, Chun'an County has accelerated the pace of developing clonal early-sprouting tea. By early 2007, Chun'an County had planted 53,000 mu of clonal early-sprouting tea (1 mu = 667 sq m, the same below), of which 38,000 mu were in production, and another 15,000 mu still needed strengthened drought resistance and seedling protection, with management aimed at improving the survival rate. Especially for tea gardens planted last winter and this spring, the following seedling protection measures must be effectively adopted. 1. Mulch with grass at the right time. Mulching with grass can preserve water and lower temperature, and loosen the soil; it is a key drought-resistance technique. Cutting grass

Key points of fresh tea preservation and storage technology: tea leaves are less likely to deteriorate even after long storage
● Vacuum extraction and nitrogen filling preservation. Vacuum extraction and nitrogen filling preservation uses nitrogen to replace the air inside the packaging bag, preventing tea oxidation and thereby achieving the goal of preventing tea aging and deterioration. When green tea is packaged with nitrogen in aluminum foil bags, after 6 months of storage, the vitamin C content can remain above 96%. During the nitrogen filling process, special attention must be paid to the firmness of the packaging bag seal, and insufficient nitrogen filling or gas leakage must be prevented. Before nitrogen filling packaging, first extract the air from the bag to create a vacuum state, then fill it with nitrogen and

Differences Between the Brown Marmorated Stink Bug and the Yellow-Spotted Stink Bug and Their Identification
The brown marmorated stink bug and the yellow-spotted stink bug both belong to the order Hemiptera, superfamily Pentatomoidea, family Pentatomidae, and both are pests that cause relatively serious damage to ornamental garden plants. The brown marmorated stink bug, scientific name Halyomorpha picus, is also known as the stinkwood stink bug, the stink bug, and the tea-colored stink bug. Host: this species has a wide diet and harms many garden plants such as black locust, elm, fig, lilac, pomegranate, paulownia, peach, and crabapple. Damage symptoms: adults and nymphs suck the sap of tender leaves, tender stems, and fruits, and in severe cases cause leaves to turn yellow and dry, and to fall

Production technology of wolfberry (goji) juice concentrate powder and wolfberry juice powder containing wolfberry polysaccharides
1. Technology introduction: The use of solubilization and filter-aid technologies has made the industrial production of wolfberry (goji) extract a reality. The wolfberry extract product has good instant solubility, and the solution is crystal clear and transparent with no precipitation or layering, solving technical problems such as turbidity, precipitation and layering of wolfberry juice and raising the product quality grade. Low-temperature vacuum concentration and two-stage vacuum low-temperature drying technologies give the product excellent color, aroma and taste, with very little loss of nutrients during processing. Enzyme hydrolysis technology is adopted to improve extraction efficiency and moderately adjust the viscosity of the slurry, ensuring product

Occurrence and Integrated Control Methods of Gummosis in Goji Berry
Brown lesions appeared on the branches and trunks after 15 d, along with a grayish-white mold layer, while no disease developed from the other inoculated fungi. This result is consistent with the findings of the Ningxia Academy of Agricultural Sciences. Based on the field symptom characteristics and isolation results, it is considered that Clonostachys is the pathogenic fungus causing gummosis, while Alternaria and Fusarium are saprophytic fungi of secondary infection. 3 Disease occurrence patterns 3.1 Overwintering of the pathogen and transmission routes In November, diseased goji branches and trunks with lesions were placed on the field surface and in soil at 20 m-30 cm underground respectively, then retrieved in April of the following year for isolation and culture.

Intercropping soybeans with yew can increase the survival rate
Recently, 2.46 million rooted cuttings of Maire yew (Taxus media) cultivated at a yew nursery in Youxian County, Zhuzhou, Hunan, have been growing rapidly in Tongshan Village, Yajiangqiao Town in that county, and passed expert inspection at the end of August. The nursery's new seedling-raising method of "intercropping with soybeans" has raised the survival rate of yew seedlings to more than 95%. It is reported that the successful introduction and propagation of Maire yew not only helps protect the precious wild Chinese yew (Taxus wallichiana var. mairei) resources, but also opens up broad prospects for developing this "golden plant." At present, the nursery is engaged in forestry

How to Treat Stunted Pigs: An Introduction to Integrated Traditional Chinese and Western Medicine Therapy
Stunted pigs are underdeveloped piglets with stunted growth, also called "little old pigs", "runts", or "hedgehog pigs". These pigs only eat feed without gaining meat, causing great waste of manpower, feed, and pen space in pig production as well as economic losses. 1. Symptoms: Stunted pigs have rough, disordered hair, are thin and small in build, with arched backs and sagging bellies, large heads and thick tails; some are anemic, eat normally but grow slowly, and some have alternating constipation and diarrhea; scabies or internal and external parasites are often present. 2. Causes
