In man blood group is applied to single factor. This factor is agglutinogen and is also called antigen. It is found on the surface of red blood corpuscles.
<br>
<br>Accordingly a person with `A' antigen is designated as a person with A-group, with `B' antigen as B-group, with both A and B antigens as AB-blood group and a person without any antigens is designated as O-blood group.
<br>
<br>In the case of animals blood group is applied to combinations of blood factors. So it is preferable to call it as blood group systems rather then blood groups. Each system has many factors, which are together called blood group factors.
<br>
<br>In cattle ten group systems namely A,B,C,FV,J,L,M,SU, Z and R'S' are present. Except J and L, all the other group systems have more than one group factor. For example the group factors of the group system A are designated as A{-1}, A{-2}, D, H, Z'.
<br>
<br>The grouping factors are particular serum proteins. Acquiring of each protein is an inherited character. So examination of blood sample from within a breed might eventually prove a very useful means of selection. It might also indicate what mating could be expected to result in infertility.
<br>
<br>The B-group system only has greater number of grouping factors. It has nearly 27 group factors, which are called phenogroups. Some of these are unique to particular breeds. |

this massage is in reply to Stephen
<br>-- Thanks a lot for the answer. Though, i really couldn't understand the nuances of your answer, i could, in a broad sense make out that animal's blood can be grouped as blood group systems, rather than a single blood group. well, i also want you to send the source of information. Thank You |
