Beta·lactoglobulin (BLG) - $40.00/sample

There are two genes that have been associated with Beta·lactoglobulin. When a sample is submitted for analysis, the results will be reported AA, AB or BB. In the case, AA is considered the most favorable, AB is intermediate and BB is the least favorable.

In general, animals with beta·lactoglobulin genotype of AA had increased transmitting abilities for milk yield and protein yield but decreased transmitting abilities for fat.

It has been estimated that in Holstein cattle approximately 12% of the cattle will have a beta·lactoglobulin genotype of AA, 46% will be AB and 42% will be BB.
