This study carried out on one hundred lungs of Awassi Syrian sheep
were collected randomly from Damascus countryside slaughter
houses.
This study was conducted in Ber Al-Ajam village, on a private farm, with a
group of Awassi sheep (76 ewes) in 2004-2005. A group of 57 lambs were
selected out of single born lambs and divided into two groups according to sex.
Each group was divide
d randomly into sub groups: control and experimental.
At the beginning of the experiment, at three weeks age, there were no
significant differences between the groups of lambs (p > 0.05).
This study was carried out in Hama Scientific Research Center from
04/22/2010 until 01/08/2010. Twenty eight Awassi aged 160-180 daysold,
and weighed 30 kg in average were assigned into four groups, and
continued the experiment for two (101 days)
them (11 days) introductory
period to accustom the sheep on the bush studied in order to study the
effect of olive pomace on some blood chemical components levels in
Awassi sheep the one hand, and the impact of the using olive pomace on
their live weight on the other hand.
The research was conducted on 24 ewes of Awasi sheep. The
animal study were divided into 4 groups each includes six ewes.
The first three groups were injected via variant proportions of
BST hormone ( as serial doses 40 mg, 80 mg, and 120 mg)
dail
y for 2 weeks. The fourth group was considered as control
group. It was measured the quantity of morning milk and
measurement of fat and protein and lactose one time every
week. Tissue specimen was taken from udder to study the
changes of secretive vesicles.

70 days, experimental units were rested, then left for
an adaptation period of 10 days, during the adaptation period, the animals were housed in one pen, in the end of the adaptation
period, the lambs were individually weighed, then divided
according to live weight into three equal groups of an average
(22-25)kg each.
The concentrates was the same for all groups in protein and
energy intake, but the difference was only in percentage of
SBM21%, SFM 20%, and CSM15%.
