This work was carried out at EI-Khanater EI-Khairia,
Poultry Research Station. Ani~al Production Research Institute,
Agricultural Research Center, Ministry of Agriculture,
Giza, Egypt, A.R.E.
The objectives of this experiment were to:
1- Evaluate the ~ficiency of sunfloNer raw and processed
seeds as well as meal as a source of protein and
energy in broiler’s rations
2- Study the effect of graded levels of sunflower raw
and steam heated seeds and sunflower meal as well in
broiler rations on productive performance and some blood
constituents as parameters of metabolic processes.
Two experiments were conducted to fulfill the previously
mentioned objectives:-
1- The first experiment:
Total number of 231 one-day old Arbor Acer broiler
chicks were fed on commercial diet during the first 13 days
of age as a pre-experimental period. At the 14th day, birds
were wing banded and individually weighed to the nearest 5
grams after fasting overnight, and randomly divided into 7
groups <each of 33 chicks).
Birds of each group were fed ad ~ one of the
following experimental diets which were formulated to be
isonitrogenous, isoenergetic and containing approximately
.CP (127.~rom yellow corn and soya-bean .sal ,~d 67.~rom
sunflower ground raw or processed seeds or ~al):
Group 1~ Corn-soya diet (control).
Group 2- Raw sunflower ground seeds.
e
Group 3- Steam heated sun~lower ground $eeds (at 121 C
for 15 minutes).
o
Group 4- Steam heated sunflower ground; seeds (at 121 C
for 30 minutes).
o
Group 5- Dry heated sunflower ground s~ds (at 120 C
for 15 minutes).
e
Group 6- Dry heated sunflower ground saeds (at 120 C
for 30 minutes).
Group 7- Sunflower .eal.
Digestible coefficients; of nutrients werE!determined at
the second week after applying the tested diets.
Serum total protein, albumen, globUlin, total lipids,
cholesterol, glucose, alkaline phosphatase, transaminases,
uric acid and creatinine were taken as blood parameters and
estimated at the 14th and 28th day of chick’s age.
Protein consumption, body weight gain and total protein
efficiency (T.P.E.) were estimated at th. 28th day ~ age.
11- The second experiment:
Total number of 210 day-old Arbor Acer broiler chicks
were used in this experi.ent. Chicks were fed _ co••ereial
diet -for the -first week of Clge9 a-fterwhich,ithey were randOfAly
divided into 7 groups each of 30 chicl~Si.
The experimental groups -fed isonitrogendusand isoenergetic
diets containing:
Group 1- Corn-soya diet (control).
Group 2- lOX Raw sunflower ground seeds.
Group 3- 207. Raw sunflower ground seeds.
Group 4- lOX Steam heated sun-flower glround seeds (at
121 C -for 15 minutes).
Group 5- 207. Steam heated sunflower grcUnd seeds (at
e
121 C -for 15 minutes).
Group 6- 10% Sunflower meal.
Group 7- 207. Sunflower meal.
Live body weight and weight gain were measured individ~
ually and weekly to the nearest 5 grams. Feed intake per
chick was calculated every 7 days.
Parameters a-f carcass quality were detected at the end
of the experimental period (8 weeks) on a ra.hdofll sample o-f
3 birds -from each treatment.
Chemical analysis of blood serum was carl~ied out at the
7 th and 56th day ~ chick’s age as in the first exper~
illlent.
