Abstract:
This experiment was carried out to study the effect of
addition of fish oil on the performance parameters of laying
hens and the fatty acid composition of their egg yolk. 60
hens of a commercial strain of SCWL hens at ten months of
age were fed diets containing fish oil (FO) or olien oil (OO).
Each treatment consists of 3 replicates with 10 birds per
.replicate
Egg production was recorded daily; egg weight and fatty
.acid composition of the yolk was recorded weekly
Feeding 3% FO result an increase in egg production
and egg weight. Addition of FO resulted also showed in an
increase in concentrations of saturated fatty, whereas
concentrations
of
monounsaturated
fatty
acids
and
.polyunsaturated fatty acids decreased with FO addition
It can be concluded from the present experiments that
addition of FO increased the amount of Docosahexaenoic
acid (DHA)( is an omega-3 fatty acid) and α-Linolenic acid
in egg yolk
which
accompanied by a reduction in the
amount of yolk polyunsaturated fatty acids and increase in
. yolk saturated fatty acids, Egg size and egg production
