ÓLEO ESSENCIAL EM RAÇÃO PARA POEDEIRAS LEVES NO PERÍODO DE 67 A 79 SEMANAS

Abstract

The objective was to evaluate the performance and quality of eggs of laying hens fed with essential oil composed of cinnamon and oregano. There were 300 laying hens used at 67 weeks of age of the Bovans whit strain, distributed in a completely randomized design with five treatments, six units and 10 birds per experimental. The treatments used were, Treatment 1 – Basal ration with performance enhancer (positive control), Treatment 2 – Basal ration without performance enhancer (negative control), Treatment 3 – Basal ration with 50g/ton of essential oil ration, , Treatment 4 – Basal ration with 100g/ton of essential oil ration, , Treatment 5 – Basal ration with 200g/ton of essential oil ration. Three 28-day cycles were studied, and at the end of each cycle, body weight, weight gain, feed consumption (g/bird/day), conversion (kg/kg and/dozen eggs), weight, mass and egg production. No effect was observed on performance and egg quality variables. Cinnamon and oregano-based essential oil showed the same antimicrobial effects on performance and egg quality variables for laying hen leaves in the period from 67 to 79 weeks.
