تأثير إضافة المستخلصات (المائي- الميتانول-الأسيتون) لأوراق نبات الطيون إلى مياه الشرب في الأداء الإنتاجي لدجاج اللحم

Abstract

The aim of this research is to study the effect of adding methanol, acetone and aqueous extracts of Inula viscosa L. leaves to drinking water on the productive performance of broiler chickens. This study was conducted in the Pharmacology and Microbiology Laboratory at the Faculty of Pharmacy, Tartous University. The sage leaves were collected from the Safita area in 2024, after which they were dried and stored until use.

The results of the study showed a significant increase in the average live body weight, average weekly feed consumption rate, average feed conversion ratio, and average weight of edible internal organs (liver, heart, gizzard, and spleen) for the three extracts used compared to the control treatment. The third group of methanol 80% extract achieved the highest increase in all studied indicators, as the average feed consumption of birds at the end of the experiment was 4090.21 g, an increase of 1.23% compared to the control, and the average weekly live weight was 2652.23 g, an increase of 6.01% compared to the control, while the feed conversion ratio improved and reached 1.542 compared to 1.615 for the control, The methanol extract achieved the highest increase in average liver weight 69.21g, increase of 21.59% compared to the control group, average heart weight 14.92g, increase of 21.79% compared to the control group, average gizzard weight 46.78g, increase of 29.76% compared to the control group, and average spleen weight 3.61g, increase of 71.09% compared to the control group. The results indicate that adding Inula viscosa L. extracts to drinking water led to an increase in production performance indicators of broiler chickens.
