The present study was conducted in two experiments
Experiment I: was conducted to study the effects of using different
levels of dried neem leaves as feed additive in
broiler ration
Experiment 11: was conducted to evaluate the effects of using
propolis coriander combination as feed additive in
broiler ration
Both experiments were conducted to study their effects on:
(1) Growth performance of broiler chickens. (2) Carcass quality
traits. (3) Economic efficiency (4) some serum analysis as
Cholesterol, triglyceride, Total protein, total albumin, total
globulin and glucose
(5) Leukogram and histopathological examination.
Experiment (D
A total of 72 broiler chicks were used to study the effects
different levels of dried neem leaves compared to control.
Broiler chickens in this study were allotted into four groups in
each contained 18 birds each group with 3 replicate, with 6 birds in
each one, they were fed on isocaloric and isonitrogenous diets. Feed
and water were provided ad-libitum along the duration of the trial.
The experiment extended for 6 weeks and the feeding period was
divided into 3 stages:
Starter stage: from 0-14 day in which the birds were fed diet
containing CP 23.65 % and ME 3195 kcal/kg diet.
