A digestibility experiment was carried out using 105 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 need to complete the operation of hatching to ensure that the
hatching chicks were hatched at the same time.
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.
By the time of hatching, the residual yolk sac (RYS) should be
completely internalized into the body cavity of the chick through
the navel, then the navel should be completely closed (healed).
After hatching, the RYS contents are used for general
growth
including growth of the small intestine. The aim of this study was to
verify if there is any effect of navel condition on the growth of
small intestinal villi. Jejunum samples from 200 new hatched
chicks (at the age of 1 up to 5 days), with the average of 20 chicks
per day were obtained, and divided into 2 groups: healed navels and
unhealed navels, which were collected and studied histologically.
For the first time, this study demonstrated the negative effect of
unhealed navel on the growth of small intestinal villi. The results of
this study also demonstrated by Morphometric Parameters
Measurements of small intestinal villi that the high and the surface
areas of villi were increased in healed navel chicks in comparison
with unhealed chicks.
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.
This research was carried out to study some hattching egg traits and chick weight at
day old in black type of Syrian local hens and Egyptian Fayoumi strain , and study the
differences in egg traits and chicks which come from hybrization between Syr
ian black
male and Fayoumi female.
Results showed that the average egg weight of Syrian hens was 52.33 g and of
Fayoumi hens was 46.86 g .
The fertility rate increased in hybrid egg compared with parents . It was87.94% in
hybrid compared with 84.08% in Syrian hens and 77.22% in Fayoumi strain hens.
The day old hybrid chick weight increased compared with Fayoumi chick. It was 32g
in hybrid chicks while it was 30 g in Fayoumi chicks , and it was lower compared with
black Syrian chicks (35g). Hatchability rate was 89.5% and 92.3% in Syrian local hens
and Egyptian Fayoumi hens respectively .And this rate decreased to 82.6% for the hybrid .
Chicks hatched decreased to 69.2% for hybrid compared with 72.93%for Syrian local hens
and 69.44% for Egyptian Fayoumi hens .
The mortality of hybrid chicks was 3.3% , it was lower compared with mortality of
Fayoumi chicks (6.05%) and higher compared with mortality of Syrian chicks (2.22%).
This research was carried out using a total of 60 one-day old chicks from
hybrid broiler (Hubbard). Opened house system was used for rearing on floor
pens. The chicks divided randomly into three equal groups. The first group
considered as a contro
l which was fed on a ration without supplementation of
Garlic Powder (0.0%). while the second and third were fed on a ration
supplemented with Garlic Powder by (0.5%) & (1%) respectively. All
treatments were applied beginning from one-day chicks old up to sixth week of
age. The results showed that the supplementation of Garlic Powder (0.5%) and
(1%) led to improve broiler performance: significantly increase (P<0.05) was
noticed in final live body weight 5.12 % and 3.54%; weight gain 5.26 % and
3.62% respectively comparing with control, improve feed efficiency 7.57% and
8.86%, decrease feed consumption 2.69% and 5.54%.
