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.
This study was conducted in privatefarm, using a group of 24 Kids.
the kids were from a twin born and selected directly after weaning.
The Kids were randomally divide into 4 groups and subjected to
similar environmental and nutritional conditions.
The adopted hygienic programme was implemented.
Antimicrobial compounds have been used for decades in poultry diets to increase
performance and decrease morbidity particularly in broiler chickens. However, consumer
pressure related to the potential development of antibiotic-resistant bacteria ha
s resulted in
the development of non-antibiotic feed additives that may also improve broiler erformance.
In recent years, aromatic plants and their extracts have received attention as growth and
health promoters. Such products have several advantages over commonly used commercial
antibiotics since they are residue free and they are also, generally recognized as safe and
commonly used items in the food industry. The antimicrobial properties of medical plants
and their extracts have been widely reported because they consist of many active
ompounds such as carvacrol, eugenol,which partition lipids in the bacterial cell wall and
mitochondria, disturbing the structures and rendering them more permeable.
Generally,medical plants are slightly more active against Gram-positive than Gramnegative
bacteria. Medical plants are well known for their antioxidant activity and show a
considerable effect on increasing the antioxidant capacity of chicken meat because they
consist of many of active compounds such as tocopherol, carvacrol. Spices or their active
principles have been reported to stimulate digestive secretions such as lipase, amylase and
proteases.because they consist of many active compounds such as anothol, eugenol.
Variable effects of medical plants and their extracts on the productive performance of
broiler have been reported. The majority of experimental results indicate improved body
weight gain or final body weight and feed conversion ratio.
