young yor1shire pigs weaned at 5 weeks were used for 30days period to study the effects of 4 kinds Bayer flavors(Megasweet、Frucovarom、Startarom and Kovarom) on the performance of pigs.The pigs were randomly allotted to pens(4 pigs/pen,4 pens/treatment)within blocks based on weight and sex.The experiment included 12 treatments included a L 9 (3) 4 right cross design to investigate the effects of Megasweet、Frucovarom and Startarom and the optimal individual level and combinative level.The 3 another treatments included a positive control(without flavor)、a negative control(with a imported flavor) and a treatment with addition of Kovarom.The results showed that all the 4 kinds Bayer flavors could increase the food intake and daily body gain among which the best was Startarom.The optimal level of Megasweet、Frucovarom and Startarom is 300 g/t.The level of Megasweet and Frucovarom had no significant effects on the performance of pigs when both were combined with Startarom.
