Production, reproduction, management and economical parameters obtained from
data collected from 1993 to 2012 Makui sheep research station of West
Azerbaijan province in Iran were evaluated in the present study. Traits
included of fertility, pregnancy rate, lamb weights from birth to the end of
period, survival rate of lambs, wool production weight, average daily gain
and milk production. The present value of profit computed as the difference
between total revenues and total costs per ewe per year. The numeric
derivation of each considered trait is calculated by increasing and
decreasing the average value of the trait while was kept the other characters
in the average. First all costs, revenues, profits and flock structure
determined then interned input files and running the software ECOWEIGHT. The
results showed that economic values per unit increase in the traits of birth
weight, daily gain from birth until weaning, daily gain from weaning until
end of period, conception rates ewes, little size, lamb survival, lifetime
for ewes, milk yield and wool yield were 0.66, 0.51, 0.03, 0.66, 0.25, 0.85,
0.93, 0.53 and 1, respectively. Breeding objective in Makui sheep breed were
productive wool yield, lifetime, lamb survival at weaning, conception rates
ewes, birth weight, milk yield, daily gain from birth until weaning, little
size, daily gain from weaning until end of period.
