The experiment was conducted on 24 brown laying hens at 30
weeks old and were randomly assigned to four groups, each
consisting of six laying hens and put in individual cages stacked in
accordance with the battery system in the unit of poultry fee
d at the
Faculty of Veterinary Medicine, University of Hama, in order to
study the effect of different types of oil and fat on performance,
apparent and true metabolizable energy, and apparent and true fats
digestibility.
A total of 300 one day old chicks (150 broiler chicks,150 local
Syrian chicks) were raised for 6 weeks in order to determine the
performance traits (live body weight, FCR, ADG, Breast muscle
yield) There were 2 treatments 3 replication for each .a
nd at the end
of every week all birds were weighed and feed consumption rate
were calculated in order to calculate FCR and ADG Average daily
gain and 6 birds of each group were weighed and slaughtered in
order to determine the breast muscle yield.
An experiment was carried out using 120 unsexed chicks of a
commercial broiler breed taken from a hatchery nearby the farm of
the experiment. When the chicks started to hatch the chicks were
collected without the need to complete the operation of
hatching to
ensure that the hatching chicks were hatched at the same time.
The chicks were distributed into four groups of each group divid into 6
sub groups each sub group contains 5 chicks. The chicks were fed
different diets.
