Abstract
This research aims to effect of supplementing alcoholic and aqueous extract of khalal and seedless date and date seed khalal AL-Zahdi date (Phoenix dactylifera L.) to drinking water on some of the physiological, histological and microbial traits of broilers reared under high temperature, As the study included the use of 300 chicks of one day age and with an average weight of 41 g, the unsexed rose strain, and it was distributed to five treatments, where one treatment contained 60 chicks, with three replicates for each treatment (20 chicks/replicates ) for a period of 6 weeks, the birds were exposed to temperatures at an average of (28-36 -30 ± 2 ° C) and the degree of humidity at an average of (40-60-50 ± 2%) for the times (700-1200-1900). The chicks were distributed randomly into five treatments as follows: - The first treatment (T1), the control treatment, without any addition to drinking water, the second treatment (T2) and the third (T3), adding 300 mg/liter of water from the aqueous and alcoholic extract for Al-Zahdi khalal, respectively and the fourth treatment (T4) and the fifth (T5) adding 300 mg/liter of water from aqueous and alcoholic extract for the Al-Zahdi khalal seed, respectively. The results of the study indicated that there was a significant improvement in the weekly body temperature, a significant increase in the number of lymphocytes and a significant decrease in the number of heterophill cells and the percentage of heterophill cells to lymphocytes (H/L) for all addition factors compared to With control treatment, As well as a significant increase in the concentration of total protein in blood serum and all oxidative enzymes in blood serum, noting that a significant decrease occurred in the concentration of both glucose and cholesterol at the age of 21 days and the AST enzyme and ALT enzyme at the age of 42 days. The preference was in favor of T3 and T5, as was the significant increase in all the studied histological traits. Also, there was a significant decrease in the number of E. Coli bacteria in the ileum area only, and a significant increase in the number of Lactobacilli bacteria in the jejunum and ileum regions. We conclude from the study that the use of these extracts contributed to the improvement of the studied physiological, histological and microbial characteristics of broilers reared at high temperatures, noting that T3 and T5 recorded the best results for all the studied traits.
