Abstract

The present study focused on utilization of industrial squid processing waste for preparation of silage by adding different concentrations of formic acid and best one was supplemented to the animal feed Squid processing waste was collected from a processing plant located at Cochin and commercial grade formic acid was added with different concentrations such as 25 T1 3 T2 and 35 T3 The study analyzed biochemical changes during ensilaging process of 14 days with sampling on every alternative day Changes like degree of hydrolysis protein and lipid degradation products were studied Increase in nonprotein nitrogen free α′amino nitrogen and total volatile basic nitrogen contents during ensilaging process were significant p  005 and indicated the hydrolysis of protein Slight reduction of Peroxide value from 8th day onwards showed degradation of primary lipid oxidation products which reflected as increment in secondary lipid oxidation products in later stage at 3 T2 and 35 concentration T3 T1 silage was spoiled and gave ammoniacal smell during storage However T2 silage with low pH can be used as animal feed supplement Utilization of these wastes provides more revenue to seafood and related sectorsThe authors thankfully acknowledge the Indian Council of Agricultural Research ICAR Government of India New Delhi for funding the project “Development of value added products and byproducts from low value fish and shell fish processing wastes” to carry out this study The authors are grateful to the Director Central Institute of Fisheries Technology Cochin for providing permission to publish the paper
