Further, they
hypothesized that alkaloids, flavonoids,
saponin and tannin in the extract were the
active ingredients of this plant. The properties
of tamarind seed coat extract in this
study show similar properties to antibiotic
feed additives during the period of 28-49
days of age. The average daily weight gain
of broilers that received tamarind seed coat
extract at 100mg/kg in their diet was slightly
higher than other groups.
