dc.description.abstractThe present study was conducted for a period of one year and divided to summer, monsoon and post monsoon seasons. The objective of the research was to estimate the minerals in soil, slurry, feed, fodder, dung and vermicompost and also assessment of bioaccumulation of minerals in crossbred cattle. The fodder plots were selected and placed under three treatments. The first treatment plots irrigated by pig slurry, second by cattle slurry and third by irrigation water alone. The soil, slurry and irrigation water were collected at the three different seasons for mineral estimation. The fodder yield from plots were measured. Three treatment groups of six male calves each were randomly selected and maintained under similar management and concentrate feeding for one year. The treatment groups of calves received fodder from corresponding fodder plots. The feed, fodder, blood, dung were collected for mineral estimation. Vermicompost produced from dung and fodder waste from the experimental animals was collected. The carcass traits were studied during their slaughter at Meat Technology Unit, Mannuthy and meat, liver, kidney, skin and bone samples were collected for mineral estimation. All the samples were processed and digested by microwave digestion for mineral analysis. Nitrogen element was estimated by Macro Kjeldhal method. The minerals P, K, Na, Ca, Mg, Mn, Fe, Cu, Zn, Cd, Cr and Pb were estimated using Inductively Coupled Plasma Optical Emission Spectrometer. The concentration of N and Mg was highest for first treatment in soil, slurry, fodder, dung, blood, liver, kidney and bone. The concentration of P, K, Ca, Cu was highest for second treatment group in soil, slurry, fodder, dung, bone samples. The concentration of Mn and Zn was highest for third treatment group in fodder, dung, vermicompost, meat, kidney and bone samples. The final body weight of experimental animals was highest for T1 and daily weight gain was highest for T3 animals. The total fodder yield was highest for plots irrigated with pig slurry. The bio-accumulation of heavy metals could not be detected in any animal tissue under the present study. Further studies may be required in crossbred cattle with more years of feeding trials to find out bio-accumulation of heavy metals.en_US
