This study was carried out at the poultry experimental station, Technical
Institute of Agriculture, Damascus University, Kharbo. 270 of Japanese Quail
birds, one day of age were divided equally into 3 similar groups (90each). Every
group comprised
of 3 replicates of 30 each, each replicates contained 10 cages.
Birds were housed and managed under similar conditions throughout the
experimental period which lasted from the 8 to 22 weeks of age. The birds were
fed on rations recommended by NRC and contained 1, 0.65 or 2 of DLmethionine
g/kg of ration in the first (the control), second and third groups
respectively. Results showed that using ration contained 2g DL-methionine/
1kg of ration gave a significant increase in egg weight, production and
economical efficiency value as compared to the other used rations.
This research carried out in the Video Center for Research on Animal Production of
the Faculty of Agriculture at Tishreen University with the beginning of the summer of
2010 in order to study the possibility of improving the performance of broiler
chickens
under the conditions of the coastal area and increase economic returns.
Search Results showed that the addition of black bean and thyme powder by 0.5% to a
low-energy diet led to increased average live weight of age (9-28) days totaled 864.9 g
G3)) compared to the control (without the addition), which amounted to an average live
weight has 850.7) g) of the same age
FCR feed conversion ratio stood at 2.63 at the group G1, compared with 1.89 when the
Control CSearch results also showed that the addition of 0.25% of the black bean and
thyme powder led to the live weight increase of 848.6, compared with 670.7 members G1)
g) FCR feed conversion ratio stood at 1.96 at the G4 Group added (0.25% of the black
bean powder and thyme), compared with 2.63 at the G1 group.
Thirty weaned Awassi lambs (٧٥ days old), reared in the metabolic unit at
the College of Agriculture, University of Damascus, were randomly divided into
٥ groups to study the effect of consumed crude protein level available in the
rations on the daily gain rate, live body weight and the food converting rate.
The current investigation was conducted to study some
productive properties( body weight, body weight gain, feed intake,
feed conversion ratio, carcass composition, and carcass cuts ) on
some broiler strains in Syria ( Ross, Hubbard, and Shefer ).
This experiment is done on (24) male awassi lamb whish are
divided into four categories: the first category took normal water
and is considered as control group. The other three groups took
water processed with different Magnetic Field : 500, 1500, 2000
**Gauss in a series.
This research aimed to study the effect of adding different rates of lysine on the weight and
growth of common carp fingerlings. The experiment was carried out in the laboratory for 4
months using eight glass containers (40 liters each) with four t
reatments (L0 no Lysine
addition, L1 (2%), L2 (3%), L3(4%) of the total weight of diet. Eight common carp
fingerlings (average of tall 7.5cm ± 0.05 and average of weight 12.25g ± 0.57) were
cultured in each container with Oxygen pumps and filters.
Results showed by growth rate, absolute growth rate, specific growth rate and food
conversion ratio (FCR) that the treatment L1 (2% lysine) was significantly the best
comparing to the other treatments, where FCR was (2.2) and the specific growth ratio was
(0.28 %)
