Site selection and Construction of Fox Farm

Whether the fox farm is reasonable or not directly affects the efficiency of breeding and the development of production in the future. The purpose of site selection should be based on the natural environmental conditions suitable for the biological characteristics of foxes, and should be comprehensively considered according to the production scale and development vision. Focus on feed, water and epidemic prevention conditions, but also take into account the environment, temperature, light, transportation, electricity and other conditions. Therefore, before the construction of the site, we must carefully and comprehensively survey and rational layout according to the requirements of the overall planning, and it is best to choose barren land or non-cultivated land. The area of land should be adapted to the number of foxes and the needs of future development.

1 site selection

All the conditions of site selection should be suitable for the biological characteristics of foxes. Under the condition of artificial feeding and management, foxes can grow and develop normally, reproduce and produce fur, so that foxes can give full play to the maximum potential of caged growth and obtain maximum economic benefits.

The author observed and understood that the estrus of the fox farm in the leeward and sunny hillside area of 1km from the Bohai Sea was 10 to 15 days earlier than that of the fox farm in the plain area within the range of 10km in Bayuquan District of Liaoning Province for 3 consecutive years. Therefore, the best site is a leeward and sunny hillside with good drainage, adequate water supply and good water quality. In the plain area, you can choose a higher terrain or a slight inclination to the southeast.

The site must be far away from the residential area, preferably away from the residential area 1km. The special smell of the fox is very strong, which pollutes the living environment (air, surface water) of the residents, and the environmental hygiene is difficult to control; secondly, it is not convenient for closed breeding in residential areas, and the frequent entry and exit of foreign personnel and other livestock is extremely disadvantageous to epidemic prevention; moreover, the noise in residential areas (motor vehicles, fireworks, etc.) is difficult to resist, which can easily lead to fox miscarriage, eating young, and heavy economic losses. People and animals are mixed, disputes continue, which is not good for health.

With the continuous development of the aquaculture industry, there are more and more infectious diseases, especially zoonotic ones. Some infectious bacteria lurk on soil, feed, water, tools and animals, and some emit pathogens in the air. It's easy to form cross-infection. It is a major event for the fox industry to stay away from other livestock and poultry farms in order to reduce the occurrence of diseases, which must be paid attention to.

2 Construction

The basic construction of fox farm must have management room, duty room, cage, feed processing room, technical room, fur preliminary processing room, dry feed warehouse and fence, etc. The construction of fox farm is different due to different climatic and economic conditions, but the cage should be sunny, ventilated and meet the requirements of health and epidemic prevention.

2.1 Fox shed

Fox shed is used for shading, rain and snow protection, and can be adapted to local conditions and local materials. The height of the ridge of the fox shed is 2.6 ~ 2.8m, the height of the front eaves is 1.5 ~ 2m, the width of the front eave is 5m ~ 5.5m, and the width of the working path is 1.2m. Can also use single-row fence house, width 1.0-1.5m, front wall high 80~100cm, rear wall high 60~80cm, the top is a wooden cover or asbestos tile cover, showing an inclined surface, Rain Water is not easy to leak.

2.2 Fox cage

The fox cage should be strong and durable, and the iron net should be made of thick 2~2.5mm galvanized iron wire. The mesh at the bottom of the cage is 2.5 × 2.5mm, and the mesh on the four walls and at the top is 3 × 3cm or 4 × 4cm. In general, the length, width and height of the cage of male fox are 200 × 100 × 100cm, and those of female fox are 150 × 100 × 100cm and 1.50 × 90 × 80cm, respectively. The height of the cage door is 100cm or 80cm and the width is 45cm. The length, width and height of the food trough box are 25 × 20 × 8cm respectively. On the front and bottom side of the fox cage, 5-6 mesh wires can be cut from the lower end, and the upper part of the broken end can be slightly folded to the cage. When placing the trough box, as long as the trough box is tilted slightly, the trough box can be put into the cage smoothly. The water box should be hung on the front of the fox cage.

The shelf for placing the fox cage can be made of square wood with high 50cm and wide front and rear 60cm, or bricks can be built at a suitable distance. The shelf must be firm, and then the fox cage will be put on and fixed.

2.3 production box

The production box can be made of wood or brick thick as 2.0cm. The specification of the box is long 70~80cm, wide 45cm and high 50cm. It is divided into inner and outer chambers, and the inner chamber is 45 × 45cm square, with a movable cover on it. The outer chamber is a passageway, and the inner chamber is used for childbearing. It is best to lay the inner chamber into a concave shape (a hemispherical with a smaller slope). There are 20 × 20cm channels in both the inner and outer rooms for foxes to get in and out. It is better to have a lower entrance to the inner chamber. The board of the production box should be smooth, the joint of the board should be as seamless as possible, and paper or cloth paste should be used when there is a gap.

In order to ensure the safety and quiet of the fox farm, a 1.8m high fence should be built around the fox farm, and fast-growing poplars should be planted around and in the field, which can not only beautify the environment, but also prevent the wind, but also create a better climatic zone for the fox farm.

Outsiders are prohibited from entering the field as much as possible, and disinfection equipment should be provided at the entrance and exit of the production area.
