<p>This study assessed the effects of high-fiber olive pomace (OP) and exogenous multi-enzymes (phytase, cellulase and xylanase) on broiler chickens’ growth performance, internal organs, intestinal morphology, blood traits, serum lipid profile and health.

摘要

This study assessed the effects of high-fiber olive pomace (OP) and exogenous multi-enzymes (phytase, cellulase and xylanase) on broiler chickens’ growth performance, internal organs, intestinal morphology, blood traits, serum lipid profile and health. A total of three hundred one-day-old Ross 308 chicks were randomly allocated into six treatments using a 2 × 3 factorial design involving 0 and 0.5 g/kg multi-enzymes and 0, 5, and 10% olive pomace. The diet was primarily based on corn and soybean meal. The experiment was carried out in three stages: starter, grower and finisher. The results indicated that including OP at 5% and 10% levels did not negatively impact broilers’ performance (P > 0.05). However, supplementing the diet with multi-enzymes significantly increased feed consumption, body weight, and weight gain (P < 0.05). Furthermore, chickens offered with 10% OP + multi-enzymes exhibited the best performance compared to other experimental groups. The mortality rate also showed a non-significant decline of almost 5% (P > 0.05). Additionally, administration of OP and multi-enzymes or a combination of them to the broilers’ diet improved serum lipid profile and liver enzyme activity (P < 0.05) and did not affect the relative weight and length of internal organs and intestinal histomorphology (P > 0.05). In conclusion, using multi-enzymes and a diet containing olive pomace could improve the serum lipid profile, liver enzyme activity, and overall health without adversely affecting broiler performance.
