Effect of Different Methods of Using Black Seed (Nigella sativa L.) to the Diet and Drinking Water on Qualitative Egg Traits of Laying Hens Eggs

Abstract

Abstract Research on the effect of adding powder, oil, aqueous, and alcoholic solutions of black seed (Nigella sativa), individually, on qualitative egg traits of laying hens eggs was conducted at the Agricultural Research and Experiment Station, Agriculture College, Al-Muthanna University from October 15, 2022, to January 7, 2023. There were a total of 75 laying hens (ISA Brown) employed, and they were all split up into 15 groups of 5. Each treatment’s pens were 3 by 3 metres in size, and the pens were divided into thirds such that each third held 5 hens. These are the methods of treatment: T1 (the control group) received their regular diet with no alterations made. T2: 10% powdered Nigella sativa (black seed) was added to the diet. T3: Incorporate ten percent of an alcoholic extract of black seed (Nigella sativa) into the daily ration of water consumed. T4: Incorporate ten percent of a water-based extract of black seed (Nigella sativa) into your daily water intake. T5: Ten percent oil from black seeds (Nigella sativa) was added to the rations. Our research found that compared to the other experimental treatments, adding alcoholic extract to laying hens’ drinking water resulted in statistically significant increases in shell thickness, relative weight of shell and yolk, yolk and albumin index, and Hough unit, and a statistically significant decrease in the relative weight of the albumin.
