The research was carried out using 1728 broiler chicks (shifer starbro
hybrid), They were divided into eight groups, each one consists of three
replicates with 72 birds in every repetition .The birds of all repetitions were
fattened until 49 days
in separate pen of open type walk ,and on deepbedplate
.All conditions of placement, rearing and feeding were the same for all birds of
repitition in different groups.
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.
