Feed intake and feed conversion ratio (FCR) were not influenced by dietary marigold extract
supplementation (p>0.05). The highest feed intake (4.33 kg) and best FCR (1.77) were
numerically recorded in the MG200 group, despite the lack of statistical difference (Table2). Similarly, Hasin et al. (2006) showed that feed intake of pullets was not affected with the
addition of 4% marigold in the feed, possibly because it did not feed palatability. On the other
hand, Sirri et al. (2007) reported significant enhancement of feed conversion in broilers
supplemented with marigold extract.
