4. COMPARATIVE ANALYSIS FOR DIFFERENT CHANGES IN COMPOSTING AND FERMENTATION OF POULTRY FARM WASTE by I.A. BABA1, M.T. BANDAY2, H.M. KHAN3, A.A. KHAN3, M. ADULLAH1 AND N. NISSA4
The current study was conducted in the Division of Livestock Production and Management, Faculty of Veterinary Sciences and Animal Husbandry, (SKUAST-Kashmir) during the year 2016 under the agro-climatic conditions of Kashmir Valley, to compare the physical changes and economic returns of the composting and fermentation experiments. Dead birds and poultry litter was used for this study. Based upon the comparison of composting and fermentation studies an overall higher weight reduction attained was 39.96 per cent during composting and 4.72 per cent during fermentation. Similarly, volume reduction observed was 23.75 per cent during composting and 2.75 per cent during fermentation. Higher moisture content of 51.46 per cent was observed in ferment as compared to 21.39 per cent in compost. Odour score card of 6.7 and 4.54 were respectively observed in composting and fermentation. Similarly better fly score card of 6.62 was observed during composting when compared to 4.64 during fermentation. Net profit was Rs.1950.76 during composting and Rs.124.02 during fermentation. Net profit/bin was more (Rs.162.56) in composting when compared to fermentation (Rs. 4.59).
