Do you ever have to spit between 4 and 5 month fetuses for your clients? It can be a bit of a challenge. Fetal aging under 4 months can be done with considerably more accuracy than over 4 months. Some veterinarians will age under 120 days in 5 or 10 day increments and over 4 months with only a month and/or 2-month age.
For example, a pregnancy may be recorded as 100 days for a late bred cow and an earlier bred cow may be recorded as a 5/6 meaning that it is somewhere around 5 or 6 months pregnant. Knowing the stage of pregnancy provides your clients with the data they need to manage their herds.
