ThesisItem Open Access Studies on mineral profile in feed, soil and animals in Pithoragarh district of Uttaranchal(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-05) Shukla, Saraswati; Tiwari, D.P.A survey was conducted in four villages, two each from Pithoragarh and Gangolihat Tehsils, of Pithoragarh district of Uttaranchal in order to find out the existing livestock feeding practices, macro and micro nutrients profile in soil, feeds and fodder and animals and also to establish the correlations among soil, plant and animals. Fifteen farmers under four major categories on land holding basis i.e landless (0 acre), marginal (<1 acres), small (1-2 acres) and medium (>2 acres) were selected to collect samples of soil, feeds and blood of animals of different physiological status. The collected feed, soil, water and blood samples were subjected for macro and micro nutrient analysis. The CP (14.50%) content were highest in shahtut leaves whereas, lowest in paddy straw (3.35 %). While in concentrate, CP content was highest in commercial pellet. Animals of the target area showed negative balances in DM, DCP and TDN intakes. Aneostrus, repeat breeding and other reproductive problems were higher in the villages of Gangolihat Tehsil as compared to Pithoragarh Tehsil. The soil of all the villages was deficient in calcium while other minerals were above to their corresponding critical levels. In concentrates all minerals except calcium and copper such as phosphorus, magnesium, zinc, iron, cobalt, and manganese were found above the critical levels, whereas calcium (0.156 ±0.001 per cent) and copper (7.10 ± 0.17 ppm) were below the critical level. Likewise, in roughage calcium and copper were 0.175 ± 0.006 per cent and 6.78 ± 0.17 ppm, respectively which fall below critical level while other minerals such as phosphorus, magnesium, zinc, iron, cobalt and manganese were above the critical levels. The blood serum mineral concentration except calcium, copper and manganese i.e. phosphorus, magnesium, zinc and iron were above the critical levels and not found deficient. The serum calcium (4.33 ± 0.12 mg/dl), copper (0.34 ± 0.07 ppm) and manganese (0.18 ± 0.09 ppm) concentration were deficient and were below critical levels. Soil-plant-animal correlations for different minerals did not show clear-cut picture regarding their accumulation in plants and utilization by the animals. Research findings revealed that the supplementation of calcium, copper and manganese in the ration of animals is inevitable in these two Tehsils of district Pithoragarh.ThesisItem Open Access Studies on feeding practices and strategic dietary supplementation of minerals in dairy animals of Pauri district of Uttarakhand(G.B.
