How to prevent and treat hemorrhagic ascites disease in bighead carp? A detailed guide to prevention and treatment strategies
As bighead carp has gradually become popular in the market, most ponds on the outskirts of our city have shifted from raising bighead carp as a secondary species to raising them as the main species. Bighead carp yields have grown from several dozen jin per mu when raised as a secondary species to over a thousand jin per mu now that they are the main species. Due to the increase in bighead carp farming density, the disease rate in bighead carp has also risen year by year, and mortality has climbed continuously, causing certain economic losses to farmers. Hemorrhagic ascites disease in bighead carp is an explosive infectious disease, also known as bacterial septicemia, and is caused by bacteria. Before the diseased fish die, they mostly swim slowly around the pond with darkened backs, and the mouths of the diseased fish

Detailed Explanation of the Processing Methods for Dehydrated Garlic Flakes and Sweet-and-Sour Pickled Garlic
I. Dehydrated Garlic Flakes: Select fresh garlic bulbs that are well matured, free of injury, free of pests and diseases, white in color, and large in size. After removing the stem ends, separating the cloves, and peeling, slice them while keeping them wet, then rinse them in an aqueous citric acid solution to reduce the activity of garlic enzymes. Note that rinsing must be completed within 24 hours after slicing, so as to prevent the garlic slices from producing colored pigments due to oxidation, which would affect the color of the finished product. Place the rinsed garlic slices in a temperature-controlled dehydrator and control the temperature in three stages: the temperature in the early stage should be controlled at around 60°C, the temperature should be appropriately increased in the middle stage, and in the late stage it should be controlled at 7

How to identify a sick sheep? Ten methods to help you judge accurately
First, look at the eyes. A healthy sheep has nimble, bright, spirited eyes that are clean and moist. A sick sheep has dull eyes, drooping eyes with no spirit, and slow reactions.

A healthy sheep has a neat, glossy, elastic coat. A sick sheep has a messy, lusterless coat. Fourth, look at rumination. A healthy sheep, regardless of feeding, starts ruminating 30 minutes later for 30-40 minutes, and ruminates 6-8 times in a day and night. A sick sheep ruminates less or stops. Fifth, look at movement. A healthy

How to reduce the egg breakage rate? Practical methods for poultry farmers to share
Under normal circumstances, the average egg breakage rate is 6-8%. Improving eggshell quality and reducing the egg breakage rate means increased economic income. Many factors affect the egg breakage rate of caged layers, such as equipment factors, management factors, genetic factors, nutritional factors, etc. Corresponding measures should be taken according to specific circumstances during the feeding and management process. 1. The specifications of the cage equipment should conform to the production characteristics of caged laying hens. When conditions permit, choosing single-cage single-bird cages can not only reduce the egg breakage rate, but also help give full play to the hens' production performance.

How to Distinguish Swine Dysentery from Diarrhea? A Detailed Guide to Integrated Prevention and Control Methods
Dysentery and diarrhea in pigs are relatively common, especially in large-scale pig farms. On some pig farms, the harm caused by swine dysentery and diarrhea is quite serious, particularly piglet dysentery and diarrhea, which have become key factors restricting piglet survival rates. Improving the ability to clinically distinguish swine dysentery from diarrhea is of great significance for grassroots animal disease prevention and control workers and large-scale farm (household) owners to promptly adopt prevention and control measures. 1 Differences and Classification of Dysentery and Diarrhea. Dysentery and diarrhea are both clinical symptoms. What is commonly called loose stool mostly

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.

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

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.

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
