Effect of Using Black Seed, Garlic and Licorice on Productivity Indicators of Japanese Quail

Abstract

T HIS research study aimed to investigate the impact of dietary supplementation with black seed (Nigella sativa), garlic (Allium sativum), and licorice (Glabra) on the productive indicators of 600 white quail chicks in Egypt. The experiment was conducted on a private farm in Giza from February 1, 2023, for a period of 34 days. The quail chicks were divided into eight groups, with each group consisting of an average of 75 chicks. Within each group, three replicates were created, comprising 25 quail chicks each. All groups were subjected to identical housing and care conditions throughout the 34-day study period. The control group received the standard farm system diet without any supplements, serving as the baseline group.The remaining seven experimental groups received the basal diet supplemented with different combinations of black cumin, garlic, and licorice in powder form. The supplementation levels were 0.5% for each ingredient individually and in various combinations. The results showed that the groups supplemented with Nigella sativa, garlic, and licorice demonstrated superior performance in terms of live weight index, feed conversion coefficient, low mortality rate, and achieved profit percentage. Notably, the experimental groups that included two or three types of supplements exhibited the most favorable outcomes (which gave the best performance and the highest economic return).
