Abstract

The laying efficiency and egg quality of Isa brown chickens was examined in this research in relation to various doses of Phyllanthus niruri (stonebreaker) leaf meal. Six different feed regimens T1 (0% P. niruri), T2 (antibiotics), T3 (0.2% P. niruri), T4 (0.3% Phyllanthus niruri leaf meal), T5 (0.4% P. niruri) and T6 (0.5% P. niruri) were fed to an aggregate of 192 Isa brown pullets that were 24 weeks old, utilizing a completely randomized design, with 4 replicates of 8 birds each, and 32 birds per treatment. The 12-week experiment was conducted to measure egg production indices, data on external egg measures, egg production, and analysis were gathered. The feed interventions had a significant (P<0.05) impact on hen-day egg production. At the fourth (45.00%), eighth (76.50%), and twelfth (92.71%) weeks in lay, laying hens fed T6 0.5% PNLM showed improved performance. Egg width, shell thickness, and egg shape index did not change significantly (P>0.05) between treatments for any of the characteristics examined. The ranges for egg weight, egg length, and egg shape index were 58.75–61.50 g, 49.93–55.33 mm, and 77.51–78.16%, respectively. Comparing different treatment groups, the laying hens fed P. niruri leaf meal diets (T5) displayed the highest egg weight of 61.50 g and the highest egg length of 55.33 mm in T2. For enhanced egg quality and laying productivity, P. niruri leaf meal is advised as an additive
