Abstract
The study was conducted by using 225 quail females in the production stage at the age of 50 days from one hatchery at a rate of 185g weight for 12 weeks, and randomly distributed to five experimental groups, at 45 quail females per treatment, and at a rate of 15 quail females for each replicate. The birds were exposed to temperature at a rate of (28-36-30±2°C) and relative humidity at a rate of (40-60-50±2%) for the time (700-1200-1900).The birds were fed a standard diet contain 20% crude protein and 2903kcal metabolizable energy/Kg feed. The birds were distributed randomly as follows: The first group (T1) was the control without addition to drinking water, the second (T2) and the third (T3) groups with added 300mg/L of water from the aqueous and alcoholic extract for theAl-Zahdi khalal date without pits , respectively, and the fourth (T4) and the fifth (T5) groups with added 300mg/L of water from the aqueous and alcoholic for extract Al-Zahdi Khalal dates pits, respectively. The results indicated that there was a significant increase (P≤0.01) for all adding treatments compared to the control treatment with a preference in favor of the third and fifth treatments in the traits of egg production percentage on the basis of Hen-Day (H.D), mass, cumulative number of eggs, average weekly egg weight, weekly feed consumption, and significant (P≤0.01) improvement in feed conversion efficiency in most of the experimental periods. In conclusion, the use of these extracts contributed to improve the studied production traits of Japanese quail hens exposed to heat stress, noting that the treatments T3 and T5 recorded the best results for all studied traits and for most of the experimental periods of the study.
