Diagnosis and treatment of anal bursitis and perianal fistula in dogs
Like weasels (weasels) and skunks, dogs have a pair of anal sacs that open on both sides of the anus and emit foul-smelling secretory glands that are excreted at the same time when defecating. Around the anus is often contaminated by feces and soil, and it is easy to get sick. Anal bursitis is due to some reason leading to anal sac catheter occlusion, so that the anal sac glandular secretion stored in the capsule, stimulation of mucous membrane caused by inflammation, and then the suppurative focus spread around the anus. Hair follicles, sweat glands and sebaceous glands are distributed around the anus, which produce superficial and deep suppurative lesions.

There are nine ways for bees to prevent "summer decline".
The "summer decline" is generally caused by high temperature. in order to avoid and reduce the "summer decline", the key is to prevent the heat and cool down the bee colony and create a suitable microclimate for the bee colony. The specific measures are as follows: first, the over-summer beehive should be located under the big tree or in the bamboo garden, ventilated in a cool place to avoid direct sunlight. The box seats should sit north and face south. Second, build an Arbor and cover straw on the beehive, plant pumpkin, lentils, towel gourd and other crops to climb the shed to increase the shade layer. Each beehive is covered with a water-soaked sponge between the secondary cover and the large cover.

Feed and nutrition of raccoon dogs: water
The feed of raccoon dog includes animal, plant and mineral feed and synthetic products. The supply and composition of feed have a great impact on the health, reproduction and fur quality of raccoon dogs. Artificially raised raccoon dogs do not have any choice of feed, so breeders must prepare and supply feed reasonably according to their living habits and nutritional needs in different biological periods. If the feed supply is insufficient and the dietary nutrition is not fully priced or improperly allocated in one of these periods, it will certainly affect the production effect of the whole year.

Key points of Disease Control techniques for Silkworm, Bombyx mori
In the process of rearing silkworms, the occurrence of silkworm disease is closely related to the physique of larvae, pathogens and environmental conditions. Sericulture farmers do not disinfect silkworm rooms and silkworm utensils thoroughly, extensive management techniques and poor environmental conditions during rearing, which are not conducive to the growth and development of larvae, which can easily lead to the invasion of pathogenic microorganisms and cause diseases due to the decline of larval physique, resulting in a large number of diseases of larvae and causing great economic losses to sericulture farmers. In order to effectively control the occurrence of larval diseases, during the period of rearing silkworm larvae,

The nutritional needs of foxes: energy
Organic nutrients in feed are the source of energy for foxes, which release energy in the process of metabolism in the organism. Now the calculation of the total nutritional value of the feed diet and the need for animal energy is usually expressed by metabolic energy. The usual unit of feed energy and nutritional value for fur animals is 418 kilojoules (100 kcal) of metabolic energy. The unit of feed energy is expressed in kilojoules or kilocalories. one kilocalorie is equivalent to 4.184 kilojoules, or one kilojoule is equal to 0.239 kilocalories. The variation range of basic metabolic energy per kilogram body weight of adult fox is

Rabbits should be repelled of coccidiosis in summer.
Rabbit coccidiosis is a common and most serious disease in rabbits. Rabbit coccidia belong to unicellular protozoa, which are parasitic in rabbit liver, bile duct epithelial cells and intestinal epithelial cells. When coccidiosis is parasitic, the rabbit is emaciated, anemic, rough-haired and stagnant, which eventually leads to death. The disease has no obvious seasonality and can be infected all the year round, but it occurs frequently in the hot and humid season in summer and autumn, and its distribution and epidemic are very widespread. Prevent coccidiosis: 1. To keep the rabbit house clean, always disinfect the cage with 2%-3% caustic soda water.
