These graphs are based upon the 305 Day DHIR Milk test results. We used only the data from does where height was recorded, from 1999 to the 2005. We used the actual length of lactation, not the standard 305 days. This allowed us to see the true production of does who produced extended lactations.

We broke the heights down into height ranges: under 18, 18 < 19, 19<20, 20<21, 21<22, 22- 22.5 and over 22.5 inches. The reason for this that was to make sure that each sample group was big enough to be a fair representation of that set of goats. We are including the chart that indicates the data graphed, so you can see how many animals were in that representative sample, and what we got for averages. We used Microsoft Excel for the calculations and the graphing, so we would minimize human error.

We acknowledge that this is not a truly scientific sampling. The number of under 18" and overheight animals was smaller than we would have liked, but this is the only data available. Height measurement is not standardized as errors can happen during that process, throwing off the data. There is also no way to know exactly how old the doe when she was measured, only that she was measured during that lactation.
