The effects of paulownia (<i>Paulownia tomentosa</i>) leaf extract enriched diets on meat quality, sensory attributes, and the potential economic impact of broilers

The present study was conducted to assess the effect of paulownia (Paulownia tomentosa) leaf extract (PLE) enriched diets on quality meat and economic efficiency broiler chickens. A total 180 one-day-old male chicks (Cobb) were randomly assigned four treatments with five replications each (9 birds per replicate). chickens fed corn-soybean-based supplemented different levels PLE (0, 0.1, 0.3, 0.5 g kg−1) for 42 days. results showed that inclusion up kg−1 in diet significantly improved live body weight, carcase components (liver, heart, gizzard) weights compared control group (P < 0.05).
