Abstract

Days since breeding and crown-rump length were available on 58 goat fetus from 58 Coloured German Improved (Alpine) does aborted or recovered at slaughter between 33 and 146 d after breeding. Does were 1 to 9 yr of age and weighed between 31.4 and 75.4 kg. Regression of days since conception (Y) on crown-rump length (X) was y=2.74x+30.15; R2=0.82. The regression may be used for estimating age of fetus when breeding date is unknown; it should be valid for goat breeds of similar mature body size.
