GARCES, Yeny et al. Nutritional effect of the chemical silage of fish by-products in broiler (Gallus domesticuset al.) feeding. Cuban J. Agric. Sci. [online]. 2015, vol.49, n.4, pp. 503-508. ISSN 2079-3480.

The present study was aimed at assessing the nutritional effect of including chemical silage of rainbow trout (Oncorhynchus mikiss) viscera (0, 10, 20 and 30 %) in broiler chick (Gallus domesticuset al.) diets. A completely randomized design was used and the productive and economical parameters were determined.  There were significant differences (P < 0.05) in feed consumption, live weight gain, feed conversion index, mortality, carcass yield, economic conversion index and economic profitability index.  The best results were obtained in diets including 10 and 20 % silage.  Results demonstrated that the chemical silage had a high nutritional value constituting a protein and alternative energy source for broiler feeding

Keywords : viscera; productive parameters; growth; alternative feeding.
