Effect of feeding graded levels of Pudina (Mentha arvensis) leaf powder on egg quality traits in laying hens

A feeding trial of 12 weeks duration was conducted to evaluate the effect of different levels of pudina leaf powder supplementation on egg quality traits in laying hens. A total number of 120 White leghorn laying hens of 36 weeks old were randomly assigned to 4 treatment groups (T1, T2, T3 and T4) with 6 replicates of 5 birds each. The basal diet was supplemented with pudina leaf powder containing 0, 5.0, 7.5 and 10.0 g/ kg in dietary treatment groups respectively. The feeding trial was divided into phase I (36th -39th weeks), phase II (40th -43th weeks), phase III (44th -47th weeks) and overall (36th -47th weeks). At the end of each phase, egg quality and composition traits were studied.
