| Abstract | ||
| The research was conducted to investigate the effect of oil extracted propolis (OEP) on production performance of broiler chicken . A total of 240,one day old broiler chickens (Ross) were randomly allocated into 4 equal treatments and each one was included 3 replicates . chickens in the treatment were given an ordinary diet and this treatment was regarded as a control where as ,chickens in the second ,third and fourth treatment were given the same diet with addition of OEP al alevel of 100,200 and 300 mg/kg .the experiment was lasted till the sixth weeks of age .body weights ,weight gain ,feed consumption and feed conversion rate were recorded weekly . Results showed a highly significant effect (p<0.01) of OEP on body weight in the third and fourth treatments which fed on OEP at a level 200 and 300 mg/kg during the first till the third week of age where as ,no significant effect was noticed during the fourth,fifth and sixth week. Results also showed highly significant effect (p<0.01) of OEP in third,fourth treatments concerning the mean weight gain during the first week of age while these differences were significant (p<0.05) during the second and third weeks of age and the accumulative weight gain (1-3 weeks) showed ahighly significant effect (p<0.01) in the third and fourth treatments . OEP lead to a significant effect (p<0.05) of feed consumption in the third and fourth treatment during the third and sixth weeks while the accumulative feed consumption (1-6 weeks) indicated a highly significant effect (p<0.01) .OEP showed no significant effect on feed efficiency in chickens . It was concluded that OEP led to significant effect in improvement of body weights,weight gains and feed consumption during the first till the third week of chicken age at a level of 200 and 300 mg/kg | ||
