Rabbit scabies
Rabbit scabies disease, also known as rabbit acariasis, is a kind of external parasitic disease caused by scabies mites or itch mites parasitic on the body surface of rabbits. The invasion area is wide, the incidence rate is high, the mutual infection is difficult to control. The disease is highly contagious. If it is not treated in time, the diseased rabbit can die because of gradual weight loss and weakness, and the harm is very serious. Prevention and treatment methods: do not buy sick rabbits with ear mite scabies, do not use scabies rabbits to breed. Keep the cage dry and often disinfect the rabbit cage with fire. Use 5% dicofol and 2% trichlorfon water every quarter

The technique of giving birth to the second stubble antler of deer early
There are two methods for harvesting pilose antler: saw antler and chopped antler. Among them, the saw antler generally starts from the 3-year-old deer and can be harvested twice a year, the first time in 45-50 days after the Qingming Festival, which is called "first stubble antler", and then 50-60 days after the second harvest, called "second stubble antler". In order to give birth to the second crop antler early, the following measures can be taken: 1. The regenerated antler yield of Pantianshan red deer and Tarim red deer is significantly higher than that of northeast red deer, so it is better to raise these two kinds of pure red deer in order to obtain more regenerated antler. Two. make use of hybrid excellence

Three taboos for feeding rabbits with vegetables
A bogey with a pile of stuffy yellow vegetables. Feeding rabbits with piles of stuffy yellow vegetables will cause nitrite poisoning in rabbits, and serious rabbits can die. Therefore, when feeding rabbits with vegetables, we must ensure that they are fresh, and the amount of each feeding is not too much, and it is best to feed them with other feeds. Second, avoid cruciferous vegetables. Cruciferae vegetables contain glucosinolates, which can produce some goiter to promote toxins, serious damage to the liver and kidney of rabbits. 3. Avoid using vegetables affected by pests. Feed vegetables infested with aphids, cabbage worms, etc.

The cultivation of fish fingerling in autumn
The range of water temperature in autumn is generally between 20 ℃ and 30 ℃, which is a good time for fish growth, especially for fish species with small size and poor physique, so farmers must strengthen the cultivation of fish species. After several months of breeding in spring and summer, the water quality gradually aged, the dissolved oxygen and biological bait decreased, and the number of pathogenic microorganisms increased, which will stagnate the growth of fish fingers. in particular, grass carp are more likely to get sick in such old ponds. At this time

Systematic prevention of diseases in fish and shrimp
Systematic prevention of fish and shrimp diseases refers to taking preventive measures to control the occurrence and development of fish diseases from the seedling stocking stage to the beginning of adult fishing. The occurrence of fish and shrimp disease is the result of both body and external factors, in which the infection of pathogenic microorganisms is an important factor leading to the disease of fish and shrimp. As there are pathogenic microorganisms in the aquaculture water environment, such as viruses, bacteria, molds, parasites and other pathogenic microorganisms, once the environment deteriorates, the resistance of fish and shrimp decreases, which will cause a large number of pathogenic microorganisms to invade the fish and lead to the epidemic of diseases. Because of

Ten measures for disease prevention of four major domestic fish
First, one of the main purposes of the dry pond at the bottom of the pond is to oxidize the organic matter at the bottom of the pond after being exposed to the sun for a period of time. Second, thoroughly choose massive calcium oxide without water absorption and weathering in the poison pond. Before use, it can be hydrated and turned into strongly alkaline lime powder or slurry lime water, which can kill all kinds of pathogenic bacteria and parasites, and can promote the calcification of silt and prevent the reproduction of bacteria. Reasonable density means that according to one's own culture environment and technical conditions

Measures to improve the efficacy of fish drugs
Due to the use of fish drugs in the water environment, there are many restrictive factors, so it is often difficult to achieve the ideal effect. In order to improve the effect of drug application, we must pay attention to the skills of drug application. 1. The choice of external and internal medicine when the disease occurs in the fish pond, it is necessary to diagnose the disease accurately and quickly, such as red skin, rotten Gill, white skin and other common bacterial diseases, such as red skin, rotten Gill, white skin and other common bacterial diseases, such as red skin, rotten Gill, white skin and so on. If parasitic diseases are found, the combination of internal and external medication

Rescue of "toxic water disease" of three kinds of fish
Excessive dissolved oxygen in water body will cause eutrophication of water body and cause many diseases such as bubble disease in fish. Many small bubbles are attached to the fish gills, causing the fish to lose its balance when floating or swimming. There are white air bubbles in the intestines of the fish, or there are more air bubbles on the body surface, fins and Gill filaments of the fish, and the fish body floats on the water surface, which can cause the fish to die in batches. When bubbles appear in the fish pond, first, clear water should be injected quickly and part of the pond water should be discharged at the same time, and lightly ill fish can discharge air bubbles in clear water; second, 400-60 per mu of water should be used.

Production of dried silverfish
Dry products produced by water refer to products that are directly dried without salting, seasoning or cooking. The production of raw and dried products should not use large and thick raw materials, but suitable for small products with small size, thin meat and easy rapid drying, such as silverfish, small fish and shrimp, Laver, kelp, squid, fish eggs, fish belly and so on. If the drying condition is good, the tissue structure and quality of the dried products have little change, and the rehydration performance is good, and the original color, flavor and flavor can be maintained after rehydration. The disadvantage is that there is no sterilization in the processing process, and only dehydration is used to inhibit the bacteria.
