Abstract
Poultry breeders knew nettle and used poultry feed for long time but so far no research has been done on its diuretic effects in broilers particulary as field trail. In order to investigate the effects of nettle (Urtica dioica) hydroalcoholic extract on urinary track of broilers, a broiler farm with renal disorders was selected and the study was carried out as a field trial. The capacity of each shed was 10,000 broilers (Ross’s commercial breed strain). At the age of 18 days-old, two sheds that had renal disorders with clinical mortality. In gross pathology gout, and urolithiasis was noted. Nettle (Urtica dioica) hydroalcoholic extract and one commercial drug (Urotropin) were used in this study for three days.Weightgain, mortality rate, macroscopic and microscopic examination, serum biochemical factors (urea, ceratinine, uric acid, calcium and phosphorus) were evaluated before and after treatments in both sheds. The results were analyzed using SPSS software. The results showed at the end of treatment, the nephrotic complication was significantly less (p= 0.4 and p= 0.04) and microscopic observations significantly decreases (p=0.16 and p = 0.32) in the herd treated with nettle extract respectively. Also, in biochemistry examinations there was no significant difference in the level of urea, creatinine, calcium and phosphorus of the two herds at the end of drug therapy (p= 0.07, p = 0.3, p = 0.3 and p= 0.26), but at the end of the treatment, the amount of uric acid treatment with nettle extract was significantly lower than that of the urotropin treated herd (p= 0.004).Therefore, in general, the results of this study conducted that the administration of a hydroalcoholic extract of nettle with a dose of 1 in 1000 in poultry drinking water on kidney complications had more effective results than administration of urotropin.
