Impact of Curcumin and Ground Anise Seeds dietary Supplementation on The egg quality traits of Laying Hens ..

This study investigates the effects of incorporating curcumin and ground anise seeds into the diets of laying hens on egg quality over a 12- week trial. laying hens fed graded levels of curcumin (0, 100 and 200 mg/kg feed) and ground anise seeds (0, 1%, 2%) during a 12- week trial period. 189 laying hens at 47 weeks of age having almost equal body weight (1603.91± 29.84 gram) and egg production rate (86.22 ± 1.66 %) were weighed and leg banded, Chickens were evenly distributed across 9 treatments, with each treatment consisting of 21 chickens that were further divided into 3 replicates of 7 chickens each. Body weight gain, feed consumption, egg shape index, egg specific gravity, yolk height (mm), yolk diameter (mm) and yolk index, were measured. Results obtained from the present study showed that there were no significant differences in body weight, body weight gain, Treatments supplemented with anise seeds and curcumin, especially at higher doses, showed increased feed intake. The 3rd group (2% anise seeds) consistently had the highest intake. Similarly, the 9th group (200 mg/kg curcumin + 2% anise) also showed high intake, with 117.35 g/bird/day in the third period. We can recommend supplementing diets with curcumin at level of 200 mg/kg and ground anise seeds at level of 2 % to optimize egg quality traits.
