Nutritional and Biochemical Properties of Fish Silage Prepared as an Ingredient in Poultry Feed

Fish silage was prepared from fishery wastes collected from KFDC Karnataka. Fishery wastes was added with 1:1 ratio of 3% (v/w) of formic acid and propionic acid and kept it for liquefaction. The pH was checked regularly which was maintained well below 4 and became stable. The proximate and quality parameters were analyzed periodically. The proximate parameters of the liquid silage was showing a moisture level of 81%, protein of 15%, fat of 5.78% and ash of 3.3%. Among the quality parameters PV value ranged from 2.03±0.064 to 2.14±0.062 milliequivalent/kg, TBA value from 4.06±0.02 to 4.25±0.06mg N/100g, TMA value from 2.29±0.16mg% to 3.72±0.13 mg%, TVBN value from 19.01±0.12mgN/100g to 26.33±0.19mgN/100g and TPC value of 6.4×106 cfu/g initially and then showed a decreasing trend. The quality of silage remained prime during the storage period and hence can be included as a promising ingredient in the animal feed
