ABSTRACT
The aim of the present study was to produce fish silage by lactic acid fermentation and evaluate its use in feeding of quails (Coturnix coturnix japonica). An oven-dried mixture of fish silage and soybean meal (11 w/w) was used to prepare the diets with different levels of inclusion (0, 10, 20 and 30%) and evaluate its effect on the performance and meat quality of 160 quails. The inclusion level did not affect the growth and feed conversion ratio. The carcass yield (70.3%) and sensory quality of breast meat were not significantly different among the treatments (p>0.05). However, the concentration of unsaturated fatty acids such as oleic (C181n9C), linoleic (C182n6C), linolenic (C183n3), arachidonic (C204n6), cis eicosapentaenoic (C205n3) and cis docosahexaenoic (C226n3) increased in quail breast meat with the inclusion of fish silagesoybean mixture in the diet (p<0.05). Fish silage and its use in quail diets could offer a good alternative for fish waste utilization as feedstuff component for the improvement of fatty acid composition in its breast meat.
