Abstract
This study investigated the effects of silkworm droppings(SWD) added diet feeding on chemical composition of pork loin meat. Pigs were divided into 7 treatment groups(10 pigs/group) and subjected to one of seven treatment diets(O, 1 0/0, 2 0/0, 3% SWD for 4 weeks, 1 0/0, 2 0/0, 3% SWD for 8 weeks, SWD diets; total fed diets) before slaughter. Pork loin were collected from the animals(1l0 kg body weight) slaughtered at a commercial slaughter house. Pork loin meat were aerobic packaged and then stored at$4^{\circ}C$ for 2, 5, 8, or 12 days. Samples were analyzed for TBARS, sensory evaluation, myoglobin content, fatty acid composition, amino acid and mineral content. TBARS value was not significantly different between the control and SWD treatment groups. Myoglobin content of SWD fed group pork was significantly increased than that of control group(P<0.05). Marbling score and acceptability were increased in SWD fed pork compared to those in control pork. Na, Mg, Ca, Mn and Fe content of SWD fed group pork was significantly decreased than those of control group(P<0.05). P content was significantly increased than that of control group(P< 0.05). In the change of amino acid composition, the contents of aspartic acid, serine and tyrosine were decreased by dietary SWD-supplementation, whereas the SWD-supplementation resulted in the higher glutamic acid, alanine and isoleucine. As dietary SWD was increased in feed, the content of oleic acid was significantly increased, but stearic acid was significantly decreased(P<0.05).
