This study explored the impact of sage plant extracts, known for their bioactive compounds, on the production indicators of laying hens. Thirty chickens were randomly assigned to three groups, including a control group and two experimental groups (T1 and T2) receiving sage plant aqueous extract at 0.1% and 0.2% in their diets, respectively. The egg production percentage, egg weight percentage, percentage of daily feed consumption, feed conversion coefficient, and blood calcium concentrations were measured. The results indicated that supplementation of sage extract in the diet of the laying hens under study increased daily egg production percentage and daily egg yield significantly in group T2 (87.63%, 59.7 eggs/day) and improved average egg weight (68.23 grams) in group T1. Moreover, there was no significant difference in daily feed consumption among the tested hens. A notable reduction was also observed in the feed conversion ratio to 2.09 in group T2. date: 2024-09-25 publication: Journal of World's Poultry Research (JWPR) volume: 14 number: 3 publisher: SCIENCELINE pagerange: 291-296 refereed: TRUE issn: 2322-455X official_url: https://jwpr.science-line.com/attachments/article/80/JWPR%2014(3)%20291-296,%202024.pdf j_index: scopus citation: (2024) Effects of Salvia officinalis on Production Characteristics of Laying Hens.
