Abstract

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.

Key words: viscera, productive parameters, growth, alternative feeding
