AGE ESTIMATION OF GOAT FETUS

Days since breeding and crown-rump length were available on 58 goat fe tus from 58 Coloured German Improved (Alpine) does aborted or recovere d at slaughter between 33 and 146 d after breeding. Does were 1 to 9 y r of age and weighed between 31.4 and 75.4 kg. Regression of days sinc e conception (Y) on crown-rump length (X) was y = 2.74 + 30.15; R2 = 0 .82. The regression may be used for estimating age of fetus when breed ing date is unknown; it should be valid for goat breeds of similar mat ure body size.
