USING NATURAL GROWTH PROMOTERS IN BROILER CHICKEN DIETS

Abstract

This study was carried out at the Poultry Nutrition Farm, Poultry Production Department, Faculty of Agriculture, Ain Shams University. Three experiments were conducted to determine the effect of using honey bee products] Bee honey (BH), Bee pollen (BP) and Bee propolis BPr[ as growth promoters alternative to antibiotics ]Erythromycin (ER) and Colistin sulfate (CS)[ on broiler chicks diets in the starter, grower and finisher period. Experimental design: three experiments had done cobb500, each experiment 150 chicks unsexed 1-day old broiler chicks were randomly distributed into 5 treatments, each treatment dived to 3 replicates each replicate with 10 chicks. The date collected: LBW, BWG, FC, FCR, mortality rate, Performance index (PI), European productive efficacy factor (EPPF), carcass characteristics, some of tibia measurements, some of blood parameter, intestine microbiology and intestine morphology. Experiment one: a total number of 150 unsexed 1 days old cobb broiler chicks were used in this study to assessment of using BH as growth promoter alternative antibiotics ER. Experimental groups were as follows: 1- Chicks fed the Basal diets (control). 2- Chicks fed the Basal diets supplemented with ER (0.0275%). 3- Chicks fed the Basal diets supplemented with BH (0.10%). 4- Chicks fed the basal diets supplemented with BH (0.15%). 5- Chicks fed the basal diets supplemented with BH (0.20%). The main results obtained can be summarized as follows. 1. Chicks fed basal diets supplemented with BH or ER significantly (P≤0.05) increase LBW begin (1709.11, 1740.42,1745.87 and
