Differences in lamb production between ewe lambs and mature ewes
EJ Pettigrew, RE Hickson, HT Blair… - New Zealand Journal …, 2021 - Taylor & Francis
Currently, comparisons of lamb output from either ewe lambs or mature ewes are
confounded, as the age groups are bred to different sires, and lamb at different times. The …
