Present study was conducted in Jaipur district of Rajasthan to evaluate the chemical composition and minerals status of feeds and fodders. Feeds and fodders samples were collected randomly from two tehsils of Jaipur district namely Sanganer and Shahpura and analyzed for chemical composition and mineral status. Sample of dry fodders (wheat straw, pearl millet straw and sorghum straw), green fodders (lucerne, kasni, bajra kutti, dub grass), concentrate (cotton seed cake, mustard cake, cotton seed, methi grain, wheat grain, bajra grain, barley grain and pellets) were analyzed. Among the straws, concentrates and green fodders, the highest calcium concentration was recorded in sorghum straw, pellets and Lucerne, respectively. Whereas, the phosphorus concentration was found highest in pearl millet and sorghum straw among roughages, mustard cake in concentrates and in dub grass among green fodders. The calcium and phosphorus concentration in most of the feeds and fodders was reported to be above the critical level. The magnesium concentration in all feeds and fodders was normal except in wheat straw, where it was reported to be deficient. The copper concentration was found to be deficient in all straws but adequate in concentrates and green fodders. The zinc was found to be deficient in straws and concentrates but its concentration was adequate in green fodders. The manganese concentration was found to be deficient in concentrates and iron concentration was reported as an excess in all feeds and fodders. The present study revealed that the level of certain minerals such as magnesium, copper, zinc and manganese were deficient but calcium and phosphorus concentration were above the critical level in most of feeds and fodders.
