The objective of this study was to evaluate whether the addition enzymes phytase and xylanase, isolated or associated, in liquid form after feed pelletization could improve energy utilization digestibility calcium phosphorus by broiler chickens. Three experiments were performed using 120 birds each, divided into five treatments with eight replicates per group (n = 3), identified as: experiment ...

in heat-stressed broiler chickens. One hundred and twenty chicks were allocated into four groups of 30 each. Group A (feed restriction), B restriction + L-serine), C (ad libitum) D libitum L-serine). Feed (20%) was implemented on days 7–14, L-serine (200 mg/kg) provided orally from 1–14. Seven chickens slaughtered each group at 35 old to determine meat drip loss, cooking loss pH; tibia bone wei...
