4 thoughts on “What are the breeding methods of pet dogs?”

Dog's breeding method is viviparous. Dogs are generally strong, and they can generally produce three to four cubs at a time. But if the dog is not left as a dog, it is best to perform sterilization surgery in the dog for about 6 months or later non -affection. This is conducive to the health of the dog, and it is also conducive to the breeding management of the dog owner and reducing the cost of the dog's breeding. The mammals are generally viviparous. The fertilized eggs of animals develop and produce in the uterus of female animals. The nutrition required for embryonic development can be obtained from the mother until it is born. The embryo absorbs the nutrients and oxygen in the mother's blood through the placenta and umbilical cord, and at the same time send the metabolic waste into the mother. The fetus is directly produced by the birth canal after the development of the mother's uterus is completed.
It is mainly asexual reproduction, mainly uses direct insertion methods and branches and seedlings. (1) Direct insertion This should be selected in the warm and rainy season. Hainan Province is generally from September to October. Plants with strong growth, tight and dense festivals, and growth periods are 4 to 5 months. 4 section of brown wood embolism. Gently fold the branches from the stem by hand, so that the branches are attached to the tough tissue of some main stems. Do not cut it with a knife to avoid reduced survival rates due to excessive damage and excessive water consumption. When the seedlings are collected, the base of the stem is generally adopted layer by layer by layer, once every 15 to 20 days. The seedlings should be placed in a cool place, and they must be used to make it. (2) The breeding method of cutting the seedlings The fresh branch strip is inserted on the seedbed, and the long roots are transplanted to the field. The method and time of collecting branches are the same as the direct insertion method. Put the branches should be cut on a cloudy day or evening, and it is best to pour water while patching. The branches that are inserted the next day should be placed in the open world in the evening to absorb the freshness. After the branches are inserted, the shade is performed. The shade is covered in the morning, and it is unveiled at night. In Hainan Island, you can insert a row of mango or cover the lines by the lines of the line. Water every morning and evening. After insertion, you can get root in about 10 days. After the root is rooted, you can apply 1: 8 people to urine water 3 to 4 times. After 20 days, the shade is removed. This The Hainan production area removed some branches in April before the harvest of patchouli area, transplanted in breeding nursery, and a large number of seedlings for autumn planting in August to September.
First despise Alqunsi downstairs. Can the dogs that have been ligated still conceive artificially? How many animal doctors can be ligated in China? They are all removed. The method of breeding of pet dogs is divided into natural mating and artificial fertilization. Artificial fertilization is only between male and female dogs that cannot be conceived through natural mating. To truly understand the reproduction of this technology, scientific use of artificial fertilization can control the number of conception. The pet dog breeding methods with the same variety (the same species of the subject) are mainly three types of pet dogs: In-Breeding, LINE-Breeding, and Out-Corsse (also called Different reproduction). Dogs between different varieties are called hybrid breeding (MIX).
Natural breeding and artificial reproduction. Natural reproduction is that tacky is the breeding. Generally, from April to May, it is already a period of estrus in dogs. Find a temporary partner (or long -term partner) that a master and dogs like. If the trouble of manual, it is artificial conception. Generally, this method is given to dogs that have been ligated. However, I personally think that it is better to be better.
