چکیده

The effects of processing methods viz oven-drying, acid-treatment and sun-drying on the nutritive value shrimp waste meal (SWM) was examined. Five purified diets were formulated. A basal diet (Nitrogen-free), a reference that contained whole hen’s egg three test oven-dried, acid-treated sun-dried SWM as their protein sources respectively. added to supply 100/kg crude in different at expense corn starch diet. Feed water given adlibitum throughout period experiment lasted 14days. Oven-dried had highest nitrogen-free extracts (NFE) contents (366.0; 85.4g/kg) compared (344,2; 59.6g/kg). (328.0; 42.6g/kg). ether extract samples generally low, no traces fat could be found oven-dried (SW). SW sample ash while lowest. sun dried consistently higher amounts Ca, P, Mg, K, Mn Na more than acid treated SW. latter however appreciable quantities Fe, Cu Zn comparison with processed by other two methods. Rats fed best performance (P <0.05) terms body weight. efficiency ratio (PER) Net retention (NPR) showed same trend weight changes. relative weights lungs, kidney, heart, liver spleen experimental animals did not vary significantly dietary treatment. It is concluded oven-drying seemed out employed for this study but results are poorer those obtained protein.
