A total of 1455 lambs representing the Southdown, Suffolk,
Border Leicester and Dorset Down sire breeds and Romney, Corriedale,
Dorset (Dorset Horn and Poll Dorset) and all first-cross dam breeds were
slaughtered at 3, 4½ and 6 months of age. Gross carcass returns
were estimated from carcass weights, grades and the price at the time of
slaughter. Price had a marked effect on gross returns between the three
years (1973-4 to 1975-6) for which results are reported. The range in
carcass returns within years as a percentage of the average return for
the three seasons was 25% for slaughter age, 6% for sire breeds, 10%
among pure and crossbred dams and up to 11% among sires within breeds.
