Abstract

An experiment had been carried out to examine the suitability of using the White River Nile waste and disposed fish after simple heat treatments (Sun drying, roasting, direct boiling and indirect boiling) in growers and pullets rations from the seven to the twelve week as growers and from the thirteenth up to the eighteenth week as pullets by replacing the imported concentrates. The diets were contain different levels (0, 1.5, 3.5 and 5%) of treated fish replacing concentrates were used for the two periods. The crude protein of treated fish samples were (50.75, 52.50, 50.55 and50.05%) respectively and the super concentrate 31.50%. A total of 390 birds of Hy-line W-98 at the seventh week of age, randomly distributed for groups, 5 group (30 bird/ treatment). The performance of the growers fed roasted fish (1.5%) performed high weight gain (600.17g/bird), while (5%) direct boiling fish (431.50 g/bird) was the lowest ones. The growers showed high feed intake for (1.5%) sun-dry fish i.e. 438.67 g/bird, while the lowest feed intake was at (3.5%) indirect boiled fish (372.98.66g/bird). Levels of sun-dried, roasted fish and the control gain the best weight, where indirect boiled and direct boiled fish were the lowest feed intake. Pullets fed different levels of roasted, sun dried fish and control showed high feed intake, reflected in high body weigh compared to direct and indirect boiled fish diets. The study investigated the usefulness of wasted and disposed fish after simple local heat treatments to replace imported concentrates for growers and pullets rations.
