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).

The purpose of this study is to clarify the actual conditions of the floor area of skilled nursing facilities in rural area. The thorough investigation and observation works were made from the viewpoints of floor area of the skilled nursing facilities. This article discusses about the basic condition and the floor area for daily living activities of the elderly in 3 skilled nursing facilities in west gyeongnam province. As the result, There is a wide gap between floor area ratio of skilled nursing facilities. The characteristics of the private establishment skilled nursing facilities in the west gyeongnam province were figured out through the analysis of spatial composition in skilled nursing facilities for the elderly. The skilled nursing facilities in west gyeongnam mainly focus on the living environment orientated toward the bedroom. The difficulty is to encourage the communication between the skilled nursing facility patients because the facilities are composed of small semi-public zone.

This study was conducted to investigate the effect of the addition of glycine betaine to the diet on growth performance in pigs. A total of 400 pigs were divided into 4 feeding stages(Growing I: 23.10 $\pm$ 1.43, Growing II: 37.69$\pm$ 1.62, Finishing I: 66.51 $\pm$3.44 and Finishing II: 90.42$\pm$ 2.17 kg of initial body weight) then each feeding stage was divided into 4 treatment groups(Control: 0 0/0, Tl : 0.2 0/0, T2: 0.4% and T3 : 0.6 % of glycine betaine, respectively). The average daily gain and feed efficiency of T2 and T3 were significantly increased(p< 0.05) by dietary glycine betaine in stage I, 2 and 3. This result indicates that dietary glycine betaine could influence the pig growth performance. In feeding stage 4, the average daily gain and feed efficiency were significantly increased in 0.4% glycine betaine feeding group compared with other dietary groups(p < 0.05). Results suggest that feeding the pigs 0.4 % glycine betaine could be the most efficient dietary level. Crude protein, ether extract and crude ash digestibilities of 0.4% glycine betaine fed group were significantly increased compared with those of control group(p < 0.05). However, no significant difference was found in nutrient digestibilities among glycine betaine fed groups. Apparent faecal amino acid digestibilities of 0.4% glycine betaine fed group were more significantly higher than that of control group. The 0.4% glycine betaine fed group was significantly increased in apparent faecal amino acid digestibility compared with those of other glycine betaine fed group. No significant difference was shown in amount of microflora population between control and glycine betaine fed groups. Ammonia and hydrogen sulfide gas emission were significantly decreased in 0.4% glycine betaine feeding group compared with other dietary groups(p < 0.05).

Salmonella Enteritidis (S. Enteritidis) are found in animals, humans, and environment. In addition, S. Enteritidis draws attention to the public health concerns due to carriage of antibiotic resistance traits. For these reasons, the prevalence and antibiotic resistance patterns of S. Enteritidis are significant issues with regard to public health. To address this issues, a total of 24 strains of S. Enteritidis from 164 samples collected from several slaughterhouses in Gyeong-Nam province in order for antibiotic resistance profiles. Subsequently, we characterized the genotyping by random amplification polymorphic DNA (RAPD)-PCR. As a result, very high level of resistance to protein synthesis inhibition antibiotics and most isolates were susceptible to others. Six random primers were used for RAPD-PCR to reveal genotypes of S. Enteritidis isolates. One of the primer, P1245, generated 147 distinct RAPD-PCR fragments ranging from 400~3000 bp. The number of RAPD-PCR products ranged from 4 to 8 for this primer. The RAPD-PCR fragments could be placed these strains into 3 subgroups and 2 classes by UPGMA cluster analysis. Interestingly, several S. Enteritidis that isolated from different slaughterhouses showed same genotype. These results showed only limited genetic variation among the isolates, those were grouped into a few different patterns of antibiotic resistance.

In a trial involving 240pigs, the proximate composition, physico-chemical properites, color, amino acid composition and fatty acid composition of loin muscle were investigated in feeding various finished pig feeds. The treatments included feeding control) the low-nutrient density diet(2,960cal/kg ME, 12.25% CP, 0.41% lysine and 0.70% Ca), T1) the medium-nutrient density diet(3,220cal/kg ME, 15.50% CP, 0.87% lysine and 0.90% Ca) and T2) the hight-nutrient density diet(3,350cal/kg ME, 17.50% CP, 1.05% lysine and 0.90% Ca). The crude ash contents of T1 were significantly(p〈0.05) higher than those of control and T2. The pH$_{u}$ of T2 were significantly higher than those of control and T1, but cooking loss were significantly(p〈0.05) lower than those of control. In compositions amino acid, aspartic acid, threonine, iso-leucine and histidine of T2 were higher than those of control, but proline and glycine were significantly(p〈0.05) lower then those of control. The oleic acid(18:1) contents of control were significantly higher than those of T1 and T2, but the contents of linoleic acid(C18:2) and arachidonic(C20:4) acid were significantly(p〈0.05) lower. Inconclusion, the results of the experiments suggest that the high-nutrient density diet for pigs tended to improve the postmortem pH$_{u}$ and cooking loss.

This study investigated the effects of silkworm droppings (SWD) added diet feeding on quality characteristics of pork loin meat Pigs were divided into 7 treatment groups (10 pigs/group) and subjected to one of seven treatment diets $(0,\;1\%,\;2\%\;and\; 3\%\;SWD\;for\;4 weeks,\;1\%\;2\%\;3\%$ SWD for 8 weeks, SWD diets; total fed diets) before slaughter. Pork loin were collected from the animals (110kg body weight) slaughtered at a commercial slaughterhouse. Pork loin meat were packaged aerobically and then stored at $4^{\circ}C$ for 2, 5, 8, or 12 days. Samples were analyzed for general composition, texture characteristics and physico-chemical properties. pH value was not significantly different between the control and SWD treatment groups. pH of control and SWD treatment groups were increased as the storage period passed General composition, cooking loss and texture was not significantly different between the control and SWD treatment groups. WHC of SWD treatment group was higher than that of control group. WHC of control and SWD treatment groups were significantly decreased as the storage period passed (p<0.05). Meat and fat color (CIE $L^{\ast}$, $a^{\ast}$, $b^{\ast}$) were no significant differences between the control and SWD treatment groups. $L^{\ast}$ and $b^{\ast}$ value of meat color were decreased as the storage period passed There was a not significantly difference in shear force value among control and SWD treatment groups. Shear force value was decreased significantly during storage in all treatment groups. In all results, dietary SWD-supplementation was not affected in general components, texture characteristics and physico-chemical properties. It is suggested that dietary SWD-supplementation could produce of high quality pork.
