ABSTRACT
Hanaa Hashem El - Amary . Study of the relation between the utilization of treated poultry
wastes as feed ingredient and accumulation of heavy metals in animal tissues . Unpublished

This study was canied out to investigate lhe effect of inclusion of different levels of
broiler litter (0, 15 and 30% as a percent of dry matter) in the rations of growing (18 kg live
body weight) and mature (50 kg live body weight) ewes according to tommi, (1963). Generally, in
growing period, broiler litter inclusionn in the ration improved average daly gain, natrients
digestibilities and nutritive values of the rations. Zinc and copper concentration in the
rations and blood serum increased by increasing levels of broiler litter. Additionally, protein
fractions in blood serum increased as was the case with serum urea and
• creatinine by broiler litter addition. The highest wool yield was recorded for
15%
broiler litter inclusion in the ration. The same attitude has been recorded in most
metabolites in mature period. Results suggested the possibility of including broiler litter in
the ration of ewes safelg and to the level of 30% as percentage of the diet dry matter
