The present study was planned to prove the hypothesis that kulthi or its extract cures urolithiasis (as mentioned in Unani and Ayurvedic system of medicine). For the studies, 100 day old male WLH chicks reared upto 60 days on a standard chick mash diet. The chicks were duly vaccinated: (Ranikhet F1 strain-7^th day; Infectious bursal disease – 14^th day; Ranikhet F1 strain (repeat) – 28^th day; Ranikhet (R₂B strain) – 42^nd day). The debeaking was done during the 7^th week of age. After that 50 cockerels were selected and divided into five dietary treatment groups, randomly. Each group had 10 cockerels and they were housed individually. The five groups were: I- (Control) NCNP - Normal calcium (1%), normal phosphorus (0.6%); II- HCLP- High calcium (3.25%), low phosphorus (0.4%); III- HCLP+1% NaHCO₃; IV – HCLP + 1% NaHCO₃+ Kulthi extract; V – HCLP + 1% NaHCO₃ + Kulthi extract in double amount. The diets were fed from 9 weeks of age for 5 months. Body weight and feed intake were recorded during the experimental period. At monthly interval, blood serum calcium, phosphorus and magnesium estimated. A metabolic trial was conducted at the end of experiment and cockerels were sacrified for X-ray examination of kidneys, gross and histopathology.
