Abstract
The present investigation entitled "Studies of silo types on qualities of sorghum silage" was conducted under Department of Animal Husbandry and Dairy Science, Post Graduate Institute, Dr. PDKV, Akola for period of 120 day. Three treatments were studied namely T1 with sorghum silage from pit silo, T2 with Sorghum silage from tower silo, T3 with sorghum silage from plastic bag silo respectively. The fodder crops were ensiled in three different silo types. The pit, tower and plastic bag silos had the dimensions as 3.3×3.3×3.3 ft, 2 ft diameter × 4 ft depth (cylindrical shape) and 2.46×2.46×2.46 ft with the loading capacity of 5, 2.5 and 2 quintals of fodder, respectively. The densities of chopped fodder in silos were 13.91, 19.90 and 13.44 Kg per cubic feet for pit, tower and plastic bag silo respectively. Fodder was filled into the silos layer by layer compacted every layer by continuous treading to remove air and the silos were sealed immediately with an air-tight cover once it was filled. After 90 days of fermentation period, the three silos were opened and samples were used for analysis of physical quality, estimation of pH and chemical composition.
The results revealed that pit silo had significantly (P<0.05) highest sensory score (colour, aroma and texture) followed by tower and plastic bag silo sorghum silage. The sensory score for colour were (3.67, 3.33 and 2.67), aroma (6.00, 5.33 and 5.00) and texture (3.50, 2.83 and 2.67) corresponding to T1 (pit silo), T2 (tower silo) and T3 (plastic bag silo), respectively. The flieg score of sorghum silage under various treatments i.e. T1, T2 and T3 were 114.07, 102.55 and 101.01 respectively. The lowest pH values were observed in pit (3.80) followed by tower (4.08) and plastic bag silos (4.13), respectively.
The DM and CP value 30.50, 30.31, 30.61 per cent and 5.66, 5.53, 5.44 per cent, the CF and TA value were 32.61, 32.53, 32.85 per cent and 6.41, 6.61, 6.57 per cent, the EE and NFE were 1.64, 1.59, 1.45 per cent and 53.69, 53.74, 53.69 per cent corresponding to T1 (pit silo), T2 (tower silo) and T3 (plastic bag silo), respectively.
Total cost of silage was more in T2 i.e. Rs.3510 whereas the cost of silage was less in T1 and T3 i.e. Rs.2340 and Rs.1460, respectively.
From the present investigation it is observed that the silage prepared in pit silo (T1) was found superior in physical quality and pH than other treatments. For its proximate analysis the results were non-significant. This seems that use of tower and plastic bag can become an alternative to pit silo.
Description
The present investigation entitled was undertaken during the year 2018-2019. The purpose of present investigation was to investigate the effect of silo types on chemical composition and physical quality of silage and to determine cost effective preservation technique of green fodder.
