This experiment was conducted to evaluate the effects of feeding different levels of lacquer (Rhus verniciflua Stokes) meal on the growth performance, carcass traits, fatty acid profile and meat quality of longissmuss dorsi (LD) muscle in finishing pigs. Pigs (n = 117; Landrace$\times$Yorkshire$\times$Duroc; initial body weight $80{\pm}0.4kg$) were allotted to three dietary treatments and fed lacquer at 0, 2 and 4% of the diet for five weeks. Inclusion of lacquer meal in the diets of pigs had no influence on their growth performance, carcass yield, loin eye area and fat free lean; however, pigs fed lacquer diets had lower backfat (linear, p = 0.006; quadratic, p = 0.004). Pigs fed increasing levels of lacquer meal had lower moisture (linear, p<0.001; quadratic, p = 0.008), crude fat (linear, p<0.001) and crude protein (linear, p<0.001; quadratic, p = 0.002) in LD muscle. The LD muscle of pigs fed lacquer meal had lower pH (linear and quadratic, p<0.05) at 6, 8 and 10 days, and linearly lower thio-barbituric acid reactive substances (TBARS, p<0.01) at 8 and 10 days and water holding capacity (WHC, p<0.05) at 3, 6, 8 and 10 days. The fatty acid composition of LD muscle revealed linearly lower stearic (p = 0.034) and total saturated fatty acid (p = 0.049) with increasing dietary lacquer meal levels. In general, higher lightness, redness and yellowness values were observed in LD muscle of pigs fed 2% lacquer meal on day 0 and subsequently on 3, 6, 8 and 10 days of refrigerated storage. The results of the current study suggest that lacquer meal can be incorporated up to 4% in the diet of finishing pigs without any adverse effects on performance; moreover, improvements in the meat quality during refrigerated storage can be obtained by inclusion of lacquer meal in the diet of finishing pigs.

As fashion brand logos have been used conspicuously, they have been recognized as a part of the product design. Since the 2000s, fashion designers have actively begun to apply fashion brand logos to product designs by transforming, patterning, and distorting, so the importance of fashion brand logos were emphasized. This article has attempted to establish the implications between fashion brand personality and the motif which is applied to a fashion brand logo. 27 of fashion brand logos were chosen because they are easy to access and have a history of more than 10 years. As a result, these 27 logos were categorized into 5 animal motifs: a horse, a bird, a snake, a dog and a tiger. In recent years, numerous studies have found that the appearance and behavior of an animal affects their symbol system which is recognized by humans. To deduce the symbolism which is communicated by a brand logo, archetypical symbols of 5 animals were analyzed as mentioned and the brand personality and image of 27 brands. As a result, there are implications between the archetypical symbol of animal motifs and a brand image and brand personality. A majority of the adjectives which express the archetypical symbolism of animal motifs as well as brand image and brand personality are similar. Moreover, the personalities of fashion brands categorized by animal motifs are different from each other, so how each animal motif communicates different images and symbols was explored.

Previous research in our laboratory has demonstrated the importance of lactose in phase I and II pig starter diets. Two experiments were conducted to evaluate the use of a carbohydrate by-product (food by-products) as a replacement for lactose. In Exp. I, 120 weaned pigs ($14{\pm}2d$ and 5.65kg) were allotted in a randomized complete block design (RCBD) to 10 replications with four pigs per pen. This experiment evaluated three carbohydrate sources (lactose, carbohydrate by-product, and 50-50 blend of the carbohydrate by-product and lactose). The carbohydrate sources were added at 26% in the phase I diets and 15% in the phase II diets. Phase I diets contained 7.5% spray dried plasma protein (SDP). The phase I diets were fed from d 0 to 14 and the phase II diets from d 15 to 28. There were no significant differences between carbohydrate sources on pig performance in phase I. However, during phase II pigs fed the diet with lactose had an improved gain/feed ratio (G/F) (p=0.06) compared to pigs fed the carbohydrate by-product. For the entire 28 d trial ADG, ADFI and G/F were similar for the 50-50 blend and those fed lactose. Total replacement of lactose with the carbohydrate byproduct resulted in a reduced G/F (p=0.09). Exp. 2 used 100 weaned pigs ($17{\pm}2d$ and 4.75kg) with five replications with five pigs per pen. This experiment evaluated four carbohydrate treatments (lactose, carbohydrate by-products, 50-50 blend, and corn). All phase I diets contained 3.5% SDP with the carbohydrate sources included at 15%, and were fed d 0 to 14. The phase II diets contained 7.5% of the carbohydrate sources and were fed d 15 to 27. A common phase III diet was fed d 28 to 42. During all phases pigs fed com tended to have a lower ADG than pigs fed the other carbohydrate sources with the 50-50 blend resulting in the highest ADG. The results of both experiments suggest that this carbohydrate by-product can replace at least 50% of the lactose in phase I and phase II pig starter diets.

The aim of this study was to determine the best processing conditions for producing of dried lean pork as a ready-to-serve product without using large-scale machines. Lean pork sausage was produced using 1.27% sodium chloride, 0.075% sodium polyphosphate, 0.06% sodium ascorbate, 0.075% sodium pyrophosphate, 0.009% sodium nitrite, 0.009% dextrin, 0.11% sodium glutamate and 1.4% spice mixture. The most appropriate slice thickness for drying was examined by slicing the sausage at a 0.5, 1 and 2 cm thickness. The drying temperatures were determined by drying the sausage slices at 35, 48 and $68^{\circ}$. The total drying period was for 12 hr, In order to examine the ability of this process to sterilize the pork, the raw meat materials were inoculated with Escherichia coli (E. coli). The optimal conditions for producing lean pork sausages were a 2 cm slice thickness and drying temperature of $68^{\circ}C$ for 12 hr, The moisture content water activity, color, hardness and pH were measured in the dried product. The product had a moisture content of 47.5% and a water activity of 0.93. There was a 47.7% percentage reduction in moisture. The dried product tested negative for E. coli even though the raw meat materials been inoculated with E. coli.

Objective: Research was conducted to test the effect of including fiber-rich feedstuffs in practical pig diets on nutrient digestibility, nitrogen balance and ammonia emissions from slurry. Methods: Three Vietnamese fiber sources were screened, namely cassava leaf meal (CL), cassava root residue (CR), and tofu by-product (TF). Accordingly, a control diet (Con) with 10% of dietary non-starch polysaccharides (NSP) and three test diets including one of the three fiber-rich feedstuffs to reach 15% of NSP were formulated. All formulated diets had the same level of crude protein (CP), in vitro ileal protein digestible and metabolisable energy, whereas the in vitro hindgut volatile fatty acid (VFA) production of the test diets was 12% to 20% higher than the control diet. Forty growing barrows with initial body weight at $28.6{\pm}1.93kg$ ($mean{\pm}standard$ deviation) were allocated to the four treatments. When pigs reached about 50 kg of body weight, four pigs from each treatment were used for a nitrogen balance trial and ammonia emission assessment, the remaining six pigs continued the second period of the feeding trial. Results: The TF treatment increased fecal VFA by 33% as compared with the control treatment (p = 0.07), suggesting stimulation of the hindgut fermentation. However, urinary N was not significantly reduced or shifted to fecal N, nor was slurry pH decreased. Accordingly, ammonia emissions were not mitigated. CR and CL treatments failed to enhance in vivo hindgut fermentation, as assessed by fecal VFA and purine bases. On the contrary, the reduction of CP digestibility in the CL treatment enhanced ammonia emissions from slurry. Conclusion: Dietary inclusion of cassava and tofu byproducts through an increase of dietary NSP from 10% to 15% might stimulate fecal VFA excretion but this does not guarantee a reduction in ammonia emissions from slurry, while its interaction with protein digestibility even might enhance enhanced ammonia emission.

Chitosan is a polysaccharide derived from chitin by deacetylation. Chitosan is non-toxic, biodegradable, and biocompatible, so that it can be used in wide variety of medical applications such as wound healing and antimicrobial biomaterials. It also used as dermal fillers due to its ability to inject with liquid formulations. For investigation on in vivo distribution of these chitosans, Bolton-Hunter-conjugated chitosan (Chitosan-BH) was synthesized by the reaction between the primary amino group of chitosan and N-hydroxysuccinimide ester group of Bolton-Hunter reagent. Then Chitosan-BH was radiolabeled with ¹²⁵I (Chitosan-BH-¹²⁵I) using a Chloramine-T method. The effects of each radiolabeling step on the radiolabeling yield of the final product were tested. The results showed that purification step had significant effects on the radiolabeling yield of the final product. Finally, SPECT/CT images were obtained to evaluate in vivo uptake of the radiolabeled chitosan (Chitosan-BH-¹²⁵I) in several organs. The highest uptake was found in the site of injection at 21 days post-injection. The results of this study suggest that chitosan is expected to be useful for biomaterials of dermal fillers.

Nutritive values of green and black tea by-products and anti-nutritive activity of their tannins were evaluated in an in vitro rumen fermentation using various molecular weights of polyethylene glycols (PEG), polyvinyl pyrrolidone (PVP) and polyvinyl polypyrrolidone as tannin-binding agents. Significant improvement in gas production by addition of PEG4000, 6000 and 20000 and PVP was observed only from black tea by-product, but not from green tea by-product. All tannin binding agents increased $NH_3$-N concentration from both green and black tea by-products in the fermentation medium, and the PEG6000 and 20000 showed relatively higher improvement in the $NH_3$-N concentration. The PEG6000 and 20000 also improved in vitro organic matter digestibility and metabolizable energy contents of both tea by-products. It was concluded that high molecular PEG would be suitable to assess the suppressive activity of tannins in tea by-products by in vitro fermentation. Higher responses to gas production and $NH_3$-N concentration from black tea by-product than green tea by-product due to PEG indicate that tannins in black tea by-product could suppress rumen fermentation more strongly than that in green tea by-product.

The objective of this research was to provide the characterization and method for producing anti-E. coli O157:H7 antibodies in egg-laying hens and to determine if the antibody can restrain the proliferation of E. coli O157:H7 in-vitro. Selected antigenic fractions (whole cell, outer membrane protein and lipopolysaccharide (LPS)) from E. coli O157:H7 were injected to hens in order to produce anti-E. coli O157:H7 antibodies. The immune response and the egg yolk antibodies of laying hens against the whole cell, outer membrane protein and LPS antigens were monitored by ELISA. The level of antibodies against whole cell antigen monitored through ELISA sharply increased after the initial immunization, and it was found to be maximum on day 49 however, the level was maintained up to day 70. Antibodies (5 mg/ml) directed against the whole cell inhibited E. coli proliferation 10-13 times more than outer membrane protein or LPS. The antibody response against the whole cell antigens appeared to have higher activity in restraining the proliferation of E. coli O157:H7 than antibody against outer membrane protein or LPS. Results reflected that increasing the IgY's in the egg yolk could prevent greater economic losses due to human and animal health from pathogenic bacteria i.e. E. coli O157:H7.

A 21- to 42-day feeding study was conducted in Ross male broilers to evaluate the use of dried bakery product (DBP) and the influence of adding fat at different points in the manufacturing process. Six dietary treatments were formulated using a factorial arrangement (3${\times}$2 design) with three levels of fat in the mixer (high: 4.8%, medium: 3.8% and low: 2.8%) with or without DBP (0 and 7%). Additional fat was sprayed on pellets in a post-pelleting liquid application to bring the fat content to a similar level in all diets. Data on pellet quality (before and after post-pelleting fat addition), broiler performance, nutrient digestibility and organ weights were studied. Pellets made with DBP showed higher hardness values when measured before post-pelleting fat addition (p<0.001), although DBP did not affect final pellet hardness or durability. Higher post-pelleting hardness and durability were shown by diets to which a lower level of fat had been added in the mixer (p<0.001). In general, post-pelleting fat application improved durability (p<0.05). However, broiler performance and ileal digestibility were not affected by any of the factors tested. Dietary treatments had a significant but variable effect on carcass yield (p<0.01), although there were no differences among treatments regarding breast and leg yield, abdominal fat or organ weights. The results indicate that up to 7% DBP could be used in the broiler diet without impairing performance, ileal digestibility or organ weights. The place or point of fat addition in the manufacturing process has a strong influence on pellet quality.
