How to choose venues and construction kennels

A. A large group of kennels raised in the selection field has a high topography, a dry, flat and slightly sloped sandy land, with sunny leewards, shade-free summer ventilation, and warm winter full sun. The kennel's underground position should be low to avoid low moisture. The kennel should face south or southeast, and should be in the downwind direction of the residential area, relatively quiet place, adequate water supply, good water quality, convenient transportation, easy power supply, and residential areas, traffic arteries, livestock farms, sewage pits There is a certain distance between chemical industry and others.

B. The construction of Kenshe kennels should be sturdy and durable, and must meet the dog's living habits and hygienic conditions. Each doghouse should have a separate playground. The doghouse should have a brick-and-cement structure. The doors and windows can be made of steel-wood structures. The playground is made of cement or triadic soil, with a slight slope to facilitate drainage. The steel pipe and wire mesh form a strong, durable and prevent bite, which is easy to clean, wash and disinfect. The area of ​​the kennel depends on the use and the needs of the dog. The area should not be less than 10-12 square meters, and the height should not be less than 2 meters. The dog room should be 2 to 3 square meters. Breeding bitch room is 3 to 4 square meters. Puppies can not be less than 6 to 8 square meters in size because of their living quarters.

In addition, the establishment of kennels should also pay attention to the following issues:

(1) Lighting and Ventilation: Sunlight and ventilation are important conditions for kennel hygiene. The lighting window should be 1/8 to 1/5 of the area of ​​the dog bed, install glass windows, and be ventilated and protected against mosquitoes in the summer. Natural gas exchange in the kennel installs special artificial ventilation devices.

(2) Moisture protection and drainage: Dogs are disgusted with dampness, so the establishment of kennels must be protected from moisture and moisture. The dog bed should be 20 to 30 cm above the ground. The kennels need large-caliber water pipes so that the kennels can be washed under pressure. The sewers are preferably large-caliber dark ditch. If it is an open ditch, each dog farm shall not communicate with each other to prevent infectious diseases and parasitic diseases.

(3) Heatstroke prevention and heat preservation: The standard temperature of the kennel is 17°C to 20°C in the summer and 13°C to 15°C in the winter. There should be tree shading around the kennel or shady equipment for summer heatstroke prevention. In winter dog beds should be paved soft grass or set up boxes to prevent cold attacks.

A. When the breeding dog grows and develops to a certain period, the male dog produces sperm with fertility. The female dog discharges mature eggs, and the other accessory organs are fully developed. This is called sexual maturity. However, sexual maturation does not mean reaching the age at which it can breed, because the dog body is not yet fully developed and estrus. The female dog in early estrus was swollen and vulva, and blood was excreted with mucus and began to feel restless. After 7 to 9 days, enter the estrus period. After the estrus of the older dogs, the dog's bloody discharge became noticeably lighter in color, showing anxiety and climbing across other female dogs. When the male dog climbed across the mating, he actively collapsed his waist and the tail squatted to one side to receive mating. This period can last 6-10 days. Ovulation is usually in the estrus period 1 to 2 days. When the bloody discharge is discharged for 9 to 12 days (ie, 2 to 4 days of estrus), the female and male dogs are brought into the mating site (no other dog's site) and allowed to naturally mate. Normal mating can be used to conceive, but in order to improve fertility The rate will be reassigned once every other day or the following day. Mating time to choose the best female dog is best in the morning, the general mating time is 15 to 20 minutes. The dog's gestation period is 62 days (58-64 days). Early diagnosis of pregnancy is more difficult, but in 15 to 20 days the dog can see redness and swelling of the chest, can be considered pregnant. After 40 days, the waist is getting bigger, not moving, and the weight and appetite increase. At this time, the feed should be increased appropriately. In addition, it is necessary to pay attention so that the pregnant dog can guarantee a certain amount of activity every day. When the female dog was near childbirth, the vulva and breasts were swollen and congested. White colostrum could be squeezed out. There was a blistering fluid flow from the vaginal opening and a small amount of bleeding. The day before delivery, the rectal temperature was generally reduced by 0.5 to 1.0°C. After delivery, bite the umbilical cord and remove the mucus. The female dog can take care of herself. However, if there is a lot of births, delivery can be assisted. After the puppies are born, quickly wipe the mucus in the mouth and body with a dry towel to promote breathing, sterilize the umbilical cord (2 cm from the root) with sterile velvet, cut off from the ligation point with scissors, and apply 5% sulfone, and then After the puppies are put into the farrowing box, the temperature should be maintained at 25°C, and then sent back to the female's bosom after all the animals have been produced.

B. Feeding management of puppies. After the birth of Tsai dog, the main care work is insulation, pressure prevention, full colostrum, fixed teat, timely rehydration and feeding problems. Insulation is the key to improve the survival rate. Tender dogs need to pay attention to heat preservation due to environmental changes within one week after birth, coupled with thin coats of hairs, low skin fat, incomplete development of the cerebral cortex, and poor body temperature regulation. The dog has no antibodies in the body, and the colostrum secreted by the female dog in the three days after the birth is rich in various antibodies, so the puppies should eat enough colostrum. If the female dog has more than one baby, it will often take advantage of the weak food and the unbalanced development of the dog. Therefore, it is necessary to artificially fix the teats, especially the thin young ones, to help them find milky nipples. As the puppies need more and more milk, the amount of lactation in the female dog is already in short supply. Milk is better for fresh milk. Gradually add eggs, minced meat, porridge, etc. When the puppies are born for 20 days, they can go outdoors with the female dog. Weaning can be done in 45 days or so, and the rearing and management are gradually normalized.

(1) Dog Body Cleaning Outsourcing dogs should regularly spray insecticides to remove ectoparasites. In the summer, wash the kennel with water and gently wash the dog body with water, but brush the dog body with a brush to remove floating hair and swabs. The brush should be used by each dog alone.

(2) Cleaning the kennels Every day, the feces should be cleaned and rinsed clean. In winter, the excrement should be properly reduced to reduce the number of flushes in order to maintain relative dryness. In the summer, insecticides are sprayed and sterilized once a week, and in winter when the batch of dogs is replaced, they are thoroughly disinfected once. 4. Meat Dog Feeding Technology Dog feed is animal feed, vegetable feed and seasoning feed. Animal feed is the staple food of dogs, commonly used horses, cattle, sheep, pigs, rabbits and chicken meat, egg milk and fish. Wait. Vegetable feed is divided into rice cakes and vegetables. Rice cakes include rice, wheat, sorghum, corn, etc., and green vegetables include spinach, cabbage, radish, and potatoes. Seasoning feeds include salt and soy sauce. Feed the dog regularly, quantitatively, set the location, and determine the humidity. Feeding dogs must be fixed before and after; feeding in the kennels should not be carried out everywhere; food should be moderate in temperature, not too cold and overheated, and dog food should be quantified as needed, not for too long.
