USE OF TRITICALE AS A REPLACEMENT FOR WHEAT MIDDLINGS IN DIETS FOR ATLANTIC SALMON

A study was conducted to determine the value of triticale (a hybrid between rye and wheat) as a substitute for wheat middlings in the diet of Atlantic salmon (Salmo salar). Data on growth and carcass composition of fish fed the experimental diets containing triticale were comparable to those of fish fed the control diet with wheat middlings. No differences in diet acceptability were apparent when triticale was substituted for wheat middlings in the basal ration. Though the effect of triticale substitution on pellet quality (i.e., durability) is not known, the results indicated that this hybrid grain can be used as a nutritional substitute for wheat middlings in the diet of salmonids, and that further evaluation of this potential feed ingredient is warranted. © 1990.
