Production performance and chemico-sensory characteristics of broilers fed sun-dried and oven-dried layers wastes.

Levels of 5, 7.5 and 10 percent of either SDLW [sund-dried layer wastes] and ODLW [oven-dried layer wastes] in the diets had no negating effect on feed consumption, gain in weight and feed efficiency. Dressing percentage revealed that birds fed 10 percent SDLW and 5 percent ODLW were statistically significant from the birds fed 5 percent SDLW and 7.5 and 10 percent ODLW, respectively. Simple costs and return analysis revealed that the percent rate of return on total cost of birds was highest in Treatment 2 with 69.19 percent. The feathering ability and skin pigmentation of birds were not significantly affected by feeding the different levels of SDLW and ODLW. Percent mortality, however, was relatively high in the group of birds which received 5 percent SDLW. Chemical analysis of carcass or dressed birds on dried weight basis using the breast portion showed that percent protein content and the percent nitrogen-free extract had statistical significant result among the treatment means. When statistically analyzed, birds fed levels of sun-dried layer wastes revealed that their percent nitrogen-free extracts is significantly different from those in levels of oven-dried layer wastes. However, statistical non-significant results were obtained for percent fats and ash contents, respectively. Statistically significant result was obtained for percent protein, percent fat and percent nitrogen-free extract using the thigh portion based on dried weight basis. Results showed that birds fed 10 percent ODLW and control had statistical differences from those fed other levels of both SDLW and ODLW. pH determination showed that the birds are slightly acidic but not statistically different in terms of pH. The average sensory scores from 15-individuals showed significant differences among means for color, tenderness, and juiciness using the breast portion but insignificant for flavor and off-flavor. The judges declared that for the thigh portion, the means for color were statistically different but all other parameters had insignificant differences in their means.
