The disadvantages/limitation of the breed count method are as follows: Both viable and non-viable cells are counted as there is no effective way to differentiate between the two, A suspension may contain a very high number of cells which makes this technique difficult, As high magnification is required to visualize the bacteria, it limits the volume of liquid that can be examined, Some bacterial cells are very small and thus are missed/overlooked, The precision of this depends highly on the experience of the microbiologist as some cells can be missed while manually counting, This method is tedious and not suitable in cases of suspensions with low density of microbial cells. It provides opportunity to produce good quality bull for breeding. Whenever there is inbreeding, there will be one or more common ancestors from which, part of the gene samples (gametes) arise.
