Prevention and treatment of fascioliasis in cattle and sheep
Fasciola hepatica of cattle and sheep is a serious parasitic disease caused by Fasciola hepatica parasitic in the liver and bile duct of cattle and sheep. The disease can cause acute and chronic hepatitis and cholangitis in cattle and sheep, accompanied by systemic poisoning and nutritional disorders, which reduces the production performance of cattle and sheep, causes a large number of deaths of young animals, and brings huge economic losses to animal husbandry production. The development of Fasciola hepatica needs an intermediate host, freshwater snail, so the disease is prevalent regionally, especially in rainy season and flood areas. 1. Main symptoms

Ten attentions should be paid to the immunization of chickens.
1. Chicken vaccine, also known as antigen, is a kind of biological products. Can be divided into toxic vaccine, toxic vaccine, virulent vaccine. The production method is divided into freeze-dried vaccine and wet vaccine, and the preservation method is also different. freeze-dried vaccine should be kept in a frozen freezer, wet vaccine is also called liquid vaccine, and it should be kept in a freezer of 0 ℃ ~ 8 ℃. Because the freezing equipment in rural areas is incomplete, most chicken farmers are not rich and do not have a refrigerator. Therefore, it must be used now, especially in summer, when you get the vaccine home, you must add ice to cool down, and the most

Prevention and treatment of Influenza in Gosling
The disease is a common acute, respiratory and septic infectious disease, which mainly occurs in winter and spring. Goslings of about 500 grams are the most susceptible to infection (adult geese are less likely to get sick), with a serious morbidity and mortality of 80% to 90%. Abrupt climate change, large temperature difference in goose house, long-distance transportation and poor feeding management can all lead to the occurrence of the disease. The disease is mainly transmitted by respiratory tract, and contaminated feed and drinking water can also spread the disease. The main characteristics of symptomatic diseased geese are dyspnea and large amount of serous secretions from their nostrils.

The harm of influenza virus should not be ignored during pregnancy.
Bovine influenza is an acute febrile infectious disease, which has the characteristics of strong transmission, rapid spread, rapid development and violent coming. As long as one of the cattle is infected, it will make most cattle infected in a short time, especially in the climate drastic change, the spring and autumn season with large fluctuations in cold and heat is more obvious, and the incidence is high. The barn is unhygienic, cold and damp, and the feeding management can not keep up with it. When the cattle are excited by the wind or drinking cold water, it is more likely to induce influenza when the cattle's resistance decreases. According to statistics, during the winter and spring influenza epidemic in Muling City, Heilongjiang Province, the incidence of dairy cows is as high as 1.

Diagnosis and treatment of preparagonimiasis in chickens
Paragonimiasis is a common paragonimiasis in chickens. The incidence of adult hens is high, which is one of the main reasons affecting egg production and abnormal eggs. The pathogen is paragonimus, also known as tubal fluke. The insect body is flat like a small leaf, brownish red, about 3-9 mm long and 1-5 mm wide, and has two suckers on its head. Adults are parasitic in the reproductive organs of hens, mainly in the supraluminal bursa of the fallopian tube and cloaca. The eggs are excreted from the feces and fall into the water in the snail body.

How to reduce the breakage rate of eggs in high temperature season
The problem of breakage of eggs has been plaguing every chicken farm, especially in the high temperature season, where the temperature is high, the preservation time of eggs is short, and damaged and contaminated eggs deteriorate within 2 days and cannot be sold. Therefore, this paper introduces several methods of how to reduce the breakage rate in high temperature season: the physiological characteristics of environment and temperature determine that the ideal temperature for laying hens is 18 ℃-23 ℃, and the production performance is the best in this range; when the temperature exceeds 30 ℃, the feed intake of laying hens decreases, the amount of drinking water increases, and feces increases.

Feeding of Fatty Liver Goose in Pre-feeding Period
Goose of about 12 weeks old should be selected for production of goose fat liver. At this time, the number of liver cells in geese is large, and the activity of fat synthase in liver is strong, which is beneficial to the rapid weight gain of liver. Before 2 weeks old, the geese were fed with coarse feed and grazing to reduce the feeding cost. Pre-feeding period is the transition period from grazing to house feeding, from coarse feeding to fine feeding, feeding quality in pre-feeding period directly affects the production effect of fatty liver. The key of feeding in pre-feeding period is to let geese have a gradual adaptation process, so that geese can adapt to high nutrition level diet and large concentrate feeding amount.

The reason and adding amount of feeding salt to rabbits
Sodium: widely distributed in the rabbit body, maintaining the balance of water, electrolyte and acid-base in the body, so that the rabbit body will neither "dry" nor edema; sodium can also regulate the normal physiological activity of the heart. at the same time, it can promote nerve conduction and gastrointestinal peristalsis. Chlorine: mainly distributed in extracellular fluid, is the raw material for the formation of gastric acid, is a component of gastric juice. Stomach acid can promote appetite, enhance digestion, and improve the digestion and absorption rate of protein and fat. If there is no salt in the rabbit's diet, it will arouse the rabbit's appetite.

How to detect diseased rabbits early
The Rex rabbit is delicate and sensitive to external conditions. it has the characteristics of urgent onset, quick death and quick recovery after timely treatment. As the disease of rabbits is mostly at night, therefore, feeding rabbits in the morning is cage-by-cage and litter-by-litter observation, and it is easiest to identify suspected rabbits, which can be examined, seen, touched and measured. 1. Check. Healthy rabbits have pink ears and bright eyes. If the ear color is red or lavender, it can be relieved when it is heated and put into a ventilated cage with little exercise; if the ear color is white and feels cold, it means that you drink too much cold water or catch cold.

Prevention and treatment of urea poisoning in deer
Urea is a widely used chemical fertilizer in agriculture, and it is a kind of non-protein nitrogen. The use of urea or ammonium salt in diets instead of protein to feed deer has been widely used. However, excessive preparation of urea in the diet or uneven mixing, or grazing in the areas where urea fertilizer is applied, can cause poisoning. [etiology]: urea and many non-protein nitrogen compounds are good protein substitutes and are often used as feed additives, such as urea, biuret and bisammonium phosphate. However, excessive feeding or improper feeding can produce a large amount of ammonia, which is one of the most important factors in the body.

Organization and management of mating wasps
The mating colony organizes mating for the small colony that the new queen bee lives, either on the 10th day after the removal or the 7th day after the king platform is sealed. To organize the mating group, you must first prepare the trunk. The standard beehive can be closely divided into 3 or 4 small areas with 2 or 3 gates. Each community can hold 2-3 nests and spleen, and open 1-3 mm long and 8 mm wide nest doors in different directions. The wall of the box in front of each nest is painted with different colors such as yellow, blue and white, so that the queen bee can identify her own hive. Put a box seal with baby bees in each district of the trunk.

How do racoon dogs come into being and how to prevent them?
Rugged raccoon dogs refer to commercial raccoon dogs that cannot be bred in the breeding period after litter weaning, showing that they are not long, small, bony and shaggy, and can only grow to 2.5 kilograms and 3.5 kilograms in the breeding period. Reason: there are many reasons for the formation of raccoon dogs, generally speaking, there are the following: unreasonable nutrition, nutrition is not full price, which is the main reason for the formation of stiff raccoon dogs. Breeders want to save, only feed corn flour or with very little other feed, because the feed is seriously lack of nutrition, can not meet the needs of raccoon dog growth, resulting in raccoon dog is not long, the formation of stiff raccoon dog.

Lymphosarcoma in dogs and cats
There are two types of lymphadenomas: one occurs in lymphoid organs and tissues, called malignant lymphoma, and tumor cells (lymphocytes) may be present in the peripheral blood; the other occurs in bone marrow, called lymphoid leukemia, and tumor cells (lymphocytes) are often seen in the peripheral blood. The etiology is not clear, feline leukemia virus may be part of the feline lymphosarcoma pathogen. Investigation shows that 1/3 of cats with leukemia develop into lymphosarcoma. Nearly 70% of cats with lymphosarcoma tested positive for feline leukemia virus. diagnosis
