Abstract :This study was conducted to determine the effects of different levels (0, 200, 400, 600 mg/kg) of ashwagandha (Withania somnifera) root powder (ARP) on performance, egg quality and egg lipid peroxidation in laying hens (Lohmann LSL, 36 weeks old) diets. For this purpose, a total of 4 groups were formed, one of which was control (ARP-0) and the other three were experimental groups (ARP-1, ARP-2, ARP-3). A total of 96 hens were distributed to 4-storey cages with 8 replicates in each group and 3 hens in each replicate. The experiment lasted for a total of 2 months. During this period, feed and water were given as ad-libitum and 16 hours of light and 8 hours of dark photoperiod was applied daily. The ARP-0 group was fed with basal diet and the experimental groups were fed with diets prepared by adding 200, 400 and 600 mg/kg levels of ARP to the basal diet, respectively. Except for egg weight, albumen index, Haugh unit, shell weight, yolk L* and b* and TBARs (day 0), other parameters were not affected by ARP in the diet. The highest egg weight (p<0.05) was in the ARP-2 group while the highest albumen index (p<0.05), Haugh unit (p<0.05) and shell weight (p<0.05) were in the ARP-1 group. It was determined that egg yolk L* (p<0.001) and b* (p<0.001) values were highest in ARP-1 and ARP-3 groups. Moreover, it was observed that all levels of ARP in the diet decreased the yolk TBARs (day 0) value compared to the control group (p<0.05). As a result, it can be said that ARP can improve some quality parameters and delay lipid oxidation in laying hens without adversely affecting performance.Keywords : Antioksidan, ashwagandha, performans, yumurtacı tavuk
