Chumen milk refers to the milk within the first 3 days of the dog's delivery. The colostrum is rich in various nutrients necessary for the growth and development of dogs. Globulin is the main way to obtain mother -source antibodies and the key to passively immune to the mother source antibody. The pet network reminds that the immunity of the newborn dog is very low, only 29%of the adult dog, and the immunity can increase to 77%of the adult dog after eating colostrum. Therefore, it is important to let the newborn dog eat colostrum within 8-32 hours.
The mother source antibody refers to the antibody obtained from the mother through a certain way. There are two ways to transfer the mother source antibody to the newborn dog: the female placenta and colostrum. The placenta of the dog is a vertical placenta in the endothelial chorus. Only 5%-10%of the immunoglobulin transferred to the newborn dog by the placenta, and more than 90%are obtained through colostrum. These mother -in -law antibodies play a role in early antibody infection. However, with the age of the ancestor, the mother source antibody gradually consumes and makes the dogs become more and more susceptible to the disease. At this time, although the remaining mother source antibodies in the dog's body can no longer resist the attack of the natural pathogen, it can interfere with the vaccine or bacteria The immune effect of seedlings can not be successful until the mother source antibody disappears completely. We sometimes call this period the most sensitive period of dogs (immune turning period). Therefore, some vaccine manufacturers are trying to find new types of antibody antibody interference with strong vaccines or fungi seedlings, and use the corresponding immunoagers to stimulate the immune system to mature in advance, so as to achieve the first age of the first age, so as to make the birth dog as soon as possible as soon as possible Obtained immune protection.
