Studying the effect of different levels of aqueous extract of sage (Salvia officinalis) leaves on some carcass quality traits of Chinese ducks

This study was conducted at the agricultural research station for raising ducks in AlMuthanna Governorate, from 14/12/2021 to 14/02/2022 (60 days). A total of 60 one-day-old Chinese duck chicks were reared with an average weight of 42 gm. Ducklings were prepared from local markets in Al-Diwaniyah Governorate, Chicks were held in a semi-enclosed hall with dimensions of 25 x 10 m, were randomly distributed into four treatments, each treatment was three replicates (5 chicks/replicate). It was placed in 12 pennies, an area of 1.5 x 1 m, and the experiment's parameters were as follows: the control treatment (T1), and treatments T2, T3 and T4, water extract of sage leaves was used at a concentration of 2.5, 5 and 7.5 ml per liter of drinking water, respectively. The results show that all treatments of the sage leaf extract gave the best results as a significant (P≤0.05) for carcass quality traits compared to the control treatment. The T4 treatment gave the best performance as a significant (P≤0.05) of carcass traits compared to the rest of the treatments of the aqueous extract of sage leaves.
