Introduction to Prevention and Control Methods and Technical Key Points for Chicken Mites
Chicken mites are a common external parasite of chickens. Prevention and control: (1) Thoroughly disinfect the chicken coop. (2) Soak the affected chicken's feet in warm soapy water to soften the scabs, then remove the scabs, apply 20% sulfur ointment or 10% dimecron ointment or 2% carbolic acid ointment, and apply again after an interval of several days. Using 0.1% trichlorfon solution, first soak the affected chicken's feet in the solution for 4-5 minutes, scrape off the scabs, then scrub the affected area with a small brush.

Prevention and Treatment Methods and Key Technical Points for Winter Dysentery in Cattle
1. Prevention. The transmission route of this disease is infection through the digestive tract; therefore, cattle kept indoors in winter should have their feeding management and environmental disinfection strengthened, diseased animals should be isolated and treated promptly, the equipment and secretions of diseased animals should be thoroughly disinfected, manure must be strictly prevented from contaminating feed and drinking water, and manure management and harmless treatment should be strengthened. 2. Treatment. This disease is mainly treated with symptomatic therapy. An equal-amount mixture of turpentine oil and creolin can be administered orally, 25-50 milliliters each time, 2 times per day. For severe cases, fluid replacement should be given promptly, such as glucose saline

Prevention and Control Methods and Technical Key Points for Goose Influenza
This disease is a widespread acute, respiratory and septicemic infectious disease, occurring mainly in winter and spring. Goslings weighing around 500 g are most susceptible (adult geese are less commonly affected), and in severe cases the morbidity and mortality rates reach 80-90%. Sudden climate changes, excessive temperature differences in the goose house, long-distance transport and poor feeding management can all lead to the occurrence of this disease. The disease is transmitted mainly through the respiratory tract, and contaminated feed and drinking water can also spread it. 1. Symptoms The main feature of sick geese is difficulty breathing, with large amounts of serous discharge flowing from the nostrils

Key Technical Points for Feeding and Management of Foie Gras Geese During the Pre-feeding Period
Geese of around 12 weeks of age should be selected for foie gras production. At this time, the number of liver cells in geese is relatively high, and the activity of fat-synthesizing enzymes in the liver is relatively strong, which is beneficial for rapid liver weight gain. Before 2 weeks of age, goslings are mainly raised with roughage and grazing to reduce feeding costs. The pre-feeding period is the transition from grazing to housed feeding, and from roughage to concentrate feeding. The quality of feeding during the pre-feeding period directly affects the production results of foie gras. The key to feeding during the pre-feeding period is to let the geese have a gradual adaptation process, so that they adapt to a high-nutrition diet and adapt to a large amount of concentrate feed.

Common Disease Prevention and Treatment Methods and Key Technical Points for Fish and Crabs
I. Grass carp hemorrhagic disease. Symptoms: bleeding in the fins, mouth cavity, eye sockets, muscles, and intestines, partially or entirely bright red. Prevention and treatment: 1. Broadcast dibromohydantoin or chlorine dioxide over the entire pond, using 200 grams of dibromohydantoin or chlorine dioxide per 1 mu of water surface at a depth of 1 m. Apply once more after 2-3 days. 2. Mix into bait and feed Yu'erkang, mixing 1 kg of Yu'erkang per 50 kg of feed, and feed continuously for three days. 3. Mix into bait and feed Suke, mixing 50 grams of Suke per 50 kg of feed, feeding once a day for three days as one treatment course. If combined with external application of dibromohydantoin,

What are the key technical points for feeding management of broodstock?
1. The feeding condition of broodstock directly affects the quality of gonadal development, the quality of eggs, and the survival rate of fry. Broodstock feed generally includes frozen fresh fish, mackerel, oysters, large sandworms, and small sandworms, among which small sandworms are the best, because small sandworms are suitable for large yellow croaker to swallow, and if not eaten, they will not die after sinking to the bottom, which can reduce pollution in the water. 2. When the broodstock is heated to about 20°C, the feed intake must reach at least 3% of body weight, and the feeding time is generally divided into 2 to 3 times per day according to the daily feeding condition.

Detailed Explanation of Key Technical Points for Stocking Icefish in Reservoirs
For the selection of stocking sites, choose as far as possible reservoir bays that are at a certain distance from the shore, with a water depth of about 2 m, a hard mud-sand or gravel substrate, and relatively abundant small prey organisms such as insects, and select several stocking sites at the same time for multi-point stocking, so as to avoid failure caused by improper stocking at a single point. Method for stocking fish eggs: when the fertilized eggs arrive at the destination, first place the nylon bag containing the fertilized eggs into the water, and when the water temperature inside the bag and the reservoir water temperature are basically the same (temperature difference less than 3°C), slowly and evenly scatter the fertilized eggs into the water; each release point should have a certain range

Potato Disease Prevention and Control Methods and Key Technical Points
Disease is one of the important factors affecting the yield and seed quality of winter potatoes. The main diseases of winter potatoes in Yunnan Province and their prevention and control methods are introduced as follows: Virus disease prevention and control methods: select virus-resistant varieties and virus-free seed potatoes; pull out diseased plants in the field; control aphids in a timely manner. Fungal diseases: first, late blight. Prevention and control methods: select disease-resistant varieties and disease-free seed potatoes; promptly pull out central diseased plants and carry out intertillage and weeding; chemical control. Second, early blight. Prevention and control methods: select disease-resistant varieties; chemical control. Bacterial diseases: ring rot prevention and control methods: select

Processing method and key technical points for stuffed roasted dates
Stuffed roasted dates are crisp and sweet, aromatic, and uniquely flavored. The production method is as follows: 1. Material selection: use sun-dried large and medium-sized high-quality red dates as raw material. 2. Pitting: use a pitting machine or pitting drill to remove the pit lengthwise along the date fruit. 3. Stuffing: according to the size of the date, select suitable five-spice peanut kernels and insert them into the pitted dates. 4. Baking: pour the stuffed dates into a specially made baking cage, filling about 70%-75% of the total volume; the cage

Control Methods and Technical Key Points for Silkworm Pesticide Poisoning
After silkworms suffer pesticide poisoning, they generally show symptoms such as restless crawling, swelling of the thoracic region, rearing up, vomiting fluid, trembling, and shortening of the body. After poisoning by organophosphorus pesticides (trichlorfon, dichlorvos, etc.), the silkworm's abdominal legs twitch, the front half of the body swells and elongates, and the rear half shrinks, especially with the tail becoming shortened and smaller and tilting upward toward the back. After poisoning by organonitrogen pesticides (chlordimeform, bisultap, etc.), the main symptoms are spinning silk, crawling toward the edge of the rearing bed, and obvious refusal to eat; after crawling for some time, the thoracic region becomes transparent and the silkworm slowly dies. After death, it does not
