Hi guys,

Could you maybe help me further. Do animals have z. B. (dog, cat, mouse, horse) also different blood groups? And if so, the same as humans?
And how does this behave? Please help me!

thanks
Bye

Hello Camryn,

these animal species also have different blood types.

for example cat:

As with humans, cats also have a blood group system, which consists of three blood groups:

Group A, Group B and Group AB. This system is called the AB system. The blood group 0, which still exists in humans, does not exist in cats.

From birth, cats carry antibodies (alloantibodies) in their blood, on the surface of the erythrocytes (red blood cells) against the blood group that they do not have themselves. Animals with blood group B have very strong alloantibodies against A, cats with blood group A also have these alloantibodies against B, but only very weak ones. Thus, the reactions of blood group B animals are stronger than with animals of blood group A. Here too there are reactions that are very weak and hardly noticeable.

Group AB cats do not have alloantibodies. This is a big problem for breeding. If a blood group B cat is mated with a male who has blood group A, 75% of the puppies with blood group A, which are heterozygous AB in the genotype, will result. The mother cat with blood group B passes on the alloantibodies that are against group A via the colostrum. If the kittens with blood group A or AB drink this milk with the B antibodies, which are against their blood groups, the antibodies can overcome the intestinal mucosal barrier in the first 24 to 48 hours and cause severe hemolysis in the kittens, also known as the Feline neonatal isoerythrolysis or "fading kitten syndrome" for short FNI, in which the disintegration of the erythrocytes leads to jaundice (jaundice), anemia (anemia) and hemoglobinemia, in which the puppies excrete brownish urine, in some cases as well have bloody diarrhea. The boys die from actually harmless infections within a few days after their birth. A few A-kittens develop almost completely normally in a B-cat, due to the fact that the alloantibody content is not quite as strong. Smaller reactions often occur here, such as tail necrosis (death of the tip of the tail). After 24 to 48 hours the intestinal barrier is tight, the kittens are then out of danger and can continue to be looked after by the mother.

Blood group A predominates in the cat population, a very small percentage falls into blood group B, which considerably reduces the risk of blood group intolerance. Unfortunately not so with many different races. In Somalis, for example, 10-20% have blood group B. Therefore it is very important to test both parents before starting a mating. To rule out blood group intolerance. It is recommended that only animals of blood group A be used for breeding, as there are no problems whatsoever with these animals. If you want to mate a B-cat, you should either look for a tomcat with blood group B, whereby you should be aware that only blood group B puppies can fall in this case, or if you are mated with blood group A tomcat, the Separate puppies from their mother for 48 hours immediately after birth. For the breeder, this means hand-rearing with cat milk substitutes or the possibility of suckling the puppies from a blood group A foster cat.

Greetings
Carsten

Hi Carsten

I still have a question, how about other animals? And which blood groups are there or not?
thanks

Hello Camryn,

Unfortunately, it is not that easy to describe in a few sentences: - (.... Have a look at http://www.blutgruppe.info or use a search engine.

I wish you success
