evaluation of the feeding value of waste fig, with and without enzyme supplementation, in broiler chickens

two experiments were conducted to investigate the feeding value of waste fig along with its effect on broilers, performance. in the first experiment, the amen content of fig was determined through total collection method using 10 adult leghorn cockerels. in the second experiment, 240 day-old male ross broiler chicks were randomly alloted to 6 experimental groups of 4 replicates of 10 chicks each. the treatments consisted of diets of different levels of fig (0, 5 and 10%) along with two enzyme levels (0 and 0.04%). according to the first experiment, the amen content of the waste fig was 2640 kcal/kg. the results of the second experiment indicated that the use of fig wastage did not have any adverse effect on such performance traits as body weight, daily gain, feed intake and feed conversion ratio. adding enzyme to the diets significantly increased feed intake in a 0-21 day period (p< 0.05), but it did not have exhibit any other significant effect on performance traits. there was no significant interaction between dietary fig and enzyme levels. also, the results indicated significant effects of fig on a few blood parameters at 42 days of age. chicks fed diets containing different levels of fig showed significantly lower blood glucose (p
