The antibacterial activity of Kasumba turate (Carthamus tintorius L.) against Salmonella pullorum and Escherichia coli as an alternative feed additive for poultry

Abstract

Abstract Kasumba turate ( Carthamus tinctorius Linn ) is a kind of traditional plant which has been widely used by the people of South Sulawesi to cure measles disease and chicken pox. Kasumba turate contains flavonoid and volatile oil. Some compounds have activity potential as antibacterial. This research aimed to determine the antibacterial activity of kasumba turate against Salmonella pullorum and Escherichia coli bacteria. This study was conducted based on a completely randomized design with 4 treatments and 5 replications. The treatment consisted of PO (tetracycline as control), P1 (0.5% kasumba turate extract), P2 (0.75% kasumba turate extract), P3 (1% kasumba turate extract), and P4 (1.25% kasumba turate extract), respectively. The results of this study showed that kasumba turate extract could inhibit the Salmonella pullorum and Escherichia coli growth with an inhibition zone of approximately 11-19 mm. Increasing the level of kasumba turate extract up to 1.25% did not show any differences of inhibition zone compared to the lower levels, however, its effectivenss was significantly lower than commercial antibiotic as the positive control. It concluded that a low level of Kasumba turate extract (0.5%) showed inhibition activity on bacterial growth so that it could be used as an alternative to feed additive poultry.
