Finn x Dorset (FD) and 35 grade Rambouillet (R) ewes were
exposed to rams in various seasons. Ewes were born in 1979
or 1980; no R ewes were born in 1980. Ewes were bred in
April, 1980 (APR80); November, 1980 (NOV80); August, 1981
(AUG81); May, 1982 (MAY82); and April, 1983 (APR83). Ewes
born in 1980 entered the study in NOV80. The analytical
model used to describe ewe performance included effects of
ewe birth year (EBY), breed/EBY, season/EBY, breed x season/EBY and ewe (random).
