Influence of sage leaf water extract on several economic characteristics of Chinese duck

Abstract

This study was conducted in a private field for duck breeding in Al-Muthanna Governorate from 12/14/2021 to 02/14/2022. One hundred twenty-one-day-old chicks were reared from Pekingese ducks, with an average weight of 42 g. Ducklings were prepared from local markets in Al-Diwaniah Governorate; chicks were raised at a semi-enclosed hall with dimensions of 25 × 10 m. Chicks were randomly distributed into four treatments; each treatment was three replicates (10 chicks/replicate) placed in 12 Pens, and the area of one pen was 1.5 × 1 m. The experiment treatments were as follows: the control treatment (T1), and other treatments, used the water extract of sage leaves at a concentration of 2.5, 5 and 7.5 ml per liter of drinking water for treatments T2, T3 and T4, respectively. The results indicate that all treatments of the sage leaf extract gave the best results for the economic parameters compared to the control treatment. The T4 treatment gave the best financial performance compared to the rest of the treatments of the aqueous extract of sage leaves. Keywords: water extract of sage leaves, economic traits, Chinese duck
