Effect of addition of ginger (Zingiber officinale), and black cumin (Nigella Sativa L.) on feed conversion ratio of white leghorn layer

Abstract

The experiment was conducted to study Effect of Addition of Ginger (Zingiber officinale), and Black Cumin (Nigella Sativa L.) on Growth Performance of White Leghorn Layer. A total one hundred fifty 28- week old 150 white leghorn laying hens were randomly divided into three replication and ten treatments, and fed a basal diet with T0- Control I.G. 0% GP+0% BCP, T1- 1% GP + 3% BCP, T2-1% GP + 4% BCP, T3-1% GP + 5% BCP, T4-2% GP+ 3% BCP, T5-2% GP+ 4% BCP, T6-2% GP+ 5% BCP, T7- 3% GP+ 3% BCP, T8-3% GP+ 4% BCP and T9-3% GP+ 5% BCP, respectively. The experiment lasted 70 days. While feed intake and feed conversion ratio (FCR) showed no significant differences between treatments, there were statistically significant variations in FCR across the groups. These findings suggest that ginger and black cumin supplementation at the tested levels may not significantly affect feed intake or overall efficiency in converting feed to production in White Leghorn layers. Further research might be needed to explore the potential benefits of these supplements on other aspects of laying hen performance or to determine optimal inclusion levels for improved FCR.
