Production of Uroliths (Urolithiasis) and effect of Kulthi on it in poultry

An experiment was conducted know the effect of kulthi on induced urolithiasis. For the experiment, 70 cockerels (male-white Leghorn) were divided into 7 groups having 10 each. They were fed 7 types of diets viz. Diet I-Control having normal calcium (1%) and normal available phosporus (ap 0.5%)-NCNP; II-high calcium (3.25%) and low up (0.3%)-HCLP (to induce urolithiasis); III-HCLP+1% NaHCO₃+, IV-HCLP+1% NH₄Cl; V-HCLP +1% NaHCO₃+Kulthi seeds, VI-HCLP + 1% NaHCO₃ + Kulthi extract and VII-HCLP+1% NaHCO₃ + double the quantity of kulthi extract. Diets were fed from 9 to 32 weeks of age. During the experimental period. body weight, calcium, phosphorus and magnesium levels were determined in all the 7 diets. In the last week of experimental period, a metabolic trial was conducted. The birds were slaughtered kidney, liver and heart were weighed. Kideny were examined for mineral deposition and subjected to histopathology. The results of study revealed that growth was affected very badly in all the groups except control. Levels of calcium, phosphorus and magnesium were at par in all the groups. Increase in the weight of kidney was found in diet 2,3,6 and 7 highest weight for heart in diet 6 and for liver in diet 7. Histopathological changes were observed in all the diets except 4. X-ray examination of kidneys showed mineral deposition and kidney damage. In diet 2,3,5,6 and 7, 55–88% kidneys and 7% in the diet 4 were affected.
