In the current study, 14 male Holstein calves aged 11-12 months were used from the Usak Cattle Breeders Association Research Farm. In this study lasting for 60 days, 14 cattle were used and divided into 2 groups as control and treatment. The feeding method, which is routinely applied in the enterprise, was applied to the control group. In addition to the same ration, 250 gr/head/day crushed anise seed powder feed additive was poured on the feed of the treatment group consisting of the other 7 animals. The live weight yields of all animals were weighed on the 30th and 60th days of the study, the individual daily live weight gains of the animals were calculated. Animals in the treatment group gained 286 gr more live weight per day. Some blood parameters (glucose, total protein, albumin, AST, GGT, cholesterol, TAS, TOS) were examined in blood samples taken from the tail vein at the beginning and end of the study. In the study, it was determined that the statistical difference between the control and experimental groups in terms of fattening performance and blood parameters was insignificant. The results of the current study have revealed that more comprehensive studies should be carried out on the addition of anise seed powder to cattle feed.
