Objective: The anti-inflammatory effects of low-level laser in burn wound model in rats were investigated. Design: Randomized controlled trial. Methods: The rats were assigned to three experimental groups. Group I received second-degree burn wounds; Group II received dressing film and low-level laser ($1.2J/cm^2$) treatment after a burn wound; Group III received dressing film and low-level laser ($2.3J/cm^2$) treatment after a burn wound. After inducing a deep second-degree burn wound, the wound was observed every day and the burn area diameter and retraction quantification at 1, 7, and 14 days were evaluated. Low-level laser was investigated on hematological parameters after 14 days. Effects of low-level laser on the inflammatory cytokines (tumor necrosis $factor-{\alpha}$ [$TNF-{\alpha}$] and interleukin-6 [IL-6]) concentrations in the serum were evaluated using immunosorbent assay kits. Results: Group III showed a significant difference in wound size on days 7 and 14 compared to Group I (p<0.05). Group II showed a significant difference in wound size on day 14 compared to Group I (p<0.05). For wound contraction percentage, both laser therapy treatment groups showed a significant difference compared with Group I (p<0.05). There was also a significant difference in wound contraction percentage in Group III compared to Group II (p<0.05). Compared with the model control group, decreased $TNF-{\alpha}$ and IL-6 levels in the serum was observed at 14 days after burn wound induction. Conclusions: The results of this study suggest that low-level laser therapy can assist in burn wound healing, which might be associated with decreased concentrations of $TNF-{\alpha}$ and IL-6 related proinflammatory cytokines.

This experiment was conducted to compare the effects of vitamin C supplemented in either feed or water on the performance and carcass characteristics of broilers during the hot season. For a 6 week feeding trial, a total of 330 broiler chicks (Ross, 4 d old, average 57 g BW) were alloted to five treatments. The treatments of vitamin C (VC) supplementation were 1) 0 ppm VC, 2) 10 ppm VC in feed, 3) 20 ppm VC in feed, 4) 5 ppm VC in water and 5) 10 ppm VC in water. During the starter phase (0-3 week), chicks on non-supplemented group grew slower (p<0.01) than the supplemented ones, and a similar trend was also noted during finisher stage and the overall stage. Feed intake was significantly (p<0.05) higher in supplemented groups and higher when fed in feed as compared with water during all stages. But feed conversion efficiency was significantly improved in non-supplemented groups compared to supplemented ones in finisher and overall stage. The digestibility of gross energy and ether extract was significantly (p<0.05) higher during starter phase in supplemented, given in feed, and at higher levels as compared with non-supplemented, given in water, and at lower levels, respectively. The bone resistance was significantly (p<0.05) higher in supplemented, supplied in feed groups as compared with their counterparts. Except breast meat, the dressing percentage and abdominal fat were also higher in supplemented group and the dressing percentage was significantly (p<0.05) higher in VC supplemented in feed as to water, but no effect of supplementation was noticed on meat color when compared between the methods of feeding (feed vs. water). The levels of VC in plasma and liver increased linearly, as the level of supplementation both in feed and water increased and it was significantly (p<0.05) higher in feed group as compared with water group. It can be concluded that, retention and availability of vitamin C in feed was higher than those in water, and supplementation of VC during summer was beneficial for poultry.

Male cattle calves (n=24), 9-12 months age, with an average body weight of 120 {\pm} 20 kg were fed total mixed rations (TMR) for 120 days to determine their growth performance. Animals were divided into four groups (six of each breed): Crossbred (Friesian${\times}$Sahiwal), Dhanni, Lohani, and Cholistani. The data obtained were analyzed using analysis of variance techniques under a completely randomized design. The average daily gain (ADG), feed efficiency (FE), and dressing percentage ranged from 639-892 g/d, 0.105-0.155 kg/kg, and 51.2-51.5%, respectively, in the different breeds. The ADG and FE did not differ between the Crossbred, Dhanni, and Lohani breeds, but these values were lower in Cholistani calves (P<0.05). The dressing percentage was similar in all breeds. The highest increase in body height was observed in Dhanni calves, but heart girth was obviously higher in Lohani calves. The feed cost per kg gain was higher for Cholistani calves but similar among Crossbred, Dhanni, and Lohani calves (P>0.05). In conclusion, Dhanni, Lohani, and Crossbred calves possess the promising potential for beef production under the rainfed (Barani) conditions of the Punjab.

This experiment was conducted to determine the effect of dietary betaine (0, 0.125%) on performance, carcass composition, pork quality and hepatic betaine-homocysteine methyltransferase (BHMT) activity of crossbred finishing barrows. Three replicates of ten pigs were used for each treatment. The results showed that average daily gain, feed intake and feed conversion were not affected by betaine. Compared with the control group, pigs treated with betaine had a 8.17% (p<0.05) decrease in carcass fat percentage, and a 8.84% (p<0.05) reduction in 10th-rib backfat thickness, but dressing percentage, percentage lean, longissimus muscle area, and average backfat thickness were not affected. There were also no significant differences in muscle color score, marbling score, pork pH value and water loss rate between the control and betaine-treated groups. Hepatic betaine-homocysteine methyltransferase (BHMT) activity was significantly increased by 13.97% (p<0.05) when pigs were offered 0.125% betaine.

This study was conducted to study the environment effects on live weight, carcass weight, dressing percentage, eye muscle area, backfat thickness, and marbling score, which are the carcass traits of Hanwoo, based on the estimates and all the possible regression for the selection of variable and significance test for 231,382 heads that underwent the carcass measurements. The average and standard deviation for the live weight, carcass weight, dressing percentage, eye muscle area, backfat thickness, and marbling score were 654.79${\pm}$91.61 kg, 362.30${\pm}$67.15 kg, 59.52${\pm}$0.03%, 81.79${\pm}$12.21 $cm^2$, 11.39${\pm}$5.40 mm, 4.38${\pm}$2.29, respectively. The live weight, carcass weight, dressing percentage, eye muscle area, backfat thickness, and marbling score for cow were 532.79${\pm}$78.38 kg, 313.40${\pm}$44.90 kg, 56.50${\pm}$0.03%, 75.24${\pm}$10.69 $cm^2$, 11.82${\pm}$5.10 mm, 4.30${\pm}$2.06, respectively, while for bull were 619.74${\pm}$93.27 kg, 376.89${\pm}$48.62 kg, 58.61${\pm}$0.02%, 85.61${\pm}$10.46 $cm^2$, 5.64${\pm}$2.71 mm, 1.41${\pm}$0.83, respectively, and for steer were 681.78${\pm}$70.72 kg, 415.23${\pm}$49.43 kg, 60.19${\pm}$0.02%, 88.29${\pm}$10.27 $cm^2$, 12.71${\pm}$5.23 mm, 5.42${\pm}$1.99, respectively. In the environmental variables selection based on the variables selection method, the examination by carcass traits suggested that the most appropriate model could be determined when five variables were selected for the live weight, carcass weight, dressing percentage, eye muscle area, and four variables for backfat thickness, and marbling score. When they were considered at a time altogether based on multiple traits, it was deemed to be desirable to insert all five variables into the variables for analysis. In addition, high significance was found by carcass traits.

Background: The aim of this work was the comparison between the carcass and the meat ewes of the regional Traditional market and the Islamic religious (Halal) market. Methods: Thirty and 20 at the end of career traditional market and Halal market ewes were slaughtered following the EC (European Council, 2009) animal welfare guidelines. Live weight of ewes was taken and dressing percentage of carcasses was calculated. On every carcass zoometric measurement and the evaluation trough the EU grid rules were performed. On the Musculus longissimus thoracis of 12 Traditional market carcasses and 11 Halal market carcasses the physical-chemical and nutritional analysis were performed. Consumer tests for liking meat ewe were performed in order to find consumer's preference level for Traditional and Halal markets ewe meat. Considering as fixed factor the ewe meat market (Traditional and Halal), results were submitted to oneway Analysis of Variance (ANOVA) and to Principal Component Analysis (PCA). Results: The Halal market ewes have shown lower dressing percentages ($42.91{\pm}0.82$ vs $46.42{\pm}0.69$) and lower conformation score ($4.5{\pm}0.5$ vs $7.8{\pm}0.4$). The Halal market meat showed higher cooking loss in oven ($37.83{\pm}1.20$ vs $32.03{\pm}1.15%$), lesser Chroma value ($18.63{\pm}0.70$ vs $21.84{\pm}0.67$), and lesser Hue angle value ($0.26{\pm}0.02$ vs $0.34{\pm}0.02$). This product had also lower fat percentage ($4.2{\pm}0.4$ vs $7.09{\pm}0.4$). The traditional market meat had higher percentage in monounsatured fatty acids (MUFA) ($43.84{\pm}1.05$ vs $38.22{\pm}1.10$), while the Halal market meat had higher percentage in ${\omega}3$ poliunsatured fatty acids (PUFA) ($5.04{\pm}0.42$ vs $3.60{\pm}0.40$). The consumer test showed as the ewe meat was appreciate by the consumers. Conclusions: Both meat typologies have shown good nutritional characteristics. The traditional market meat had higher MUFA composition, and a better MUFA/satured fatty acids (SFA) ratio, while the Halal market meat had higher PUFA composition. These results were also supported by the PCA. The consumers preferred the traditional market meat.

Copolymers of gelatin and poly (vinyl alcohol), (PVA) grafted by acrylic acid (AAc) with excellent water absorption and retention abilities under neutral conditions were successfully synthesized using $^{60}Co$ gamma radiations in presence of ammonium persulphate (APS), as water soluble initiator and sodium bicarbonate ($NaHCO_3$) as foaming agent. The optimum synthesis conditions pertaining to maximum swelling percentage were evaluated as a function of gelatin/PVA ratio, amount of water, concentration of APS, $NaHCO_3$, monomer concentration and total irradiation dose. Maximum percent swelling (1694.59%) of the copolymer, gelatin-co-PVA, was obtained at optimum $[APS]=2.92{\times}10^{-1}mol/L$, $[NaHCO_3]=7.94{\times}10^{-2}mol/L$ and 1.5 mL of water at total dose of 31.104 kGy while in case of grafted copolymer, (gelatin-co-PVA)-g-poly(AAc), maximum percent swelling (560.86%) was obtained using $8.014{\times}10^{-1}mol/L$ of AAc in 9 mL water with 31.104 kGy preirradiation dose. The pristine and grafted copolymers were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning electron Microscopy (SEM), Thermal gravimetric analysis (TGA) and X-Ray Diffraction (XRD) methods. The copolymers loaded with an antiseptic, Povidone, were used as wound dressing materials for wounded gastrocnemius muscle of mice and the results exhibit that (gelatin-co-PVA)-g-poly (AAc) copolymer is a potent wound dressing material as compared to the copolymer.

Comparisons between the Korean native pig(KNP: 75kg of slaughter weight and 240 days of age) versus Landrace(110kg of slaughter and 180 days of age) in dressing and lean meat percentages, compositions of fatty acids and amino acids and sensory evaluations on longissimus muscle are as below. Compared with Landrace, KNP had smaller percentages in dressing and lean meat percentages and a smaller backfat thickness. In retail cuts, KNP had greater percentages in shoulder butt, belly and picnic shoulder and smaller percentages in spareribs, ham and loin muscle. The KNP had greater percentages in crude fat, palmitic(C16:0) and linolenic(C18:3) acids and smaller percentages in oleic(C18:1) and linoleic(C18:2) acids, but total cholesterol content and ratios of saturated and unsaturated fatty acids and essential fatty acids did not differ between the two breeds. In amino acid composition, KNP had a greater percentage in lysine, but smaller percentages in most other amino acids. The KNP had a greater a*(redness) value in longissimus muscle(LM) color and a greater L*(whiteness) value in attached backfat color. Moreover, sensory evaluations on cooked LM showed that KNP had greater flavor, tenderness and springiness, which resulted in a greater overall acceptability. In summary, KNP, compared with Landrace, had smaller dressing and lean meat percentages, a smaller backfat thickness, greater percentages in popular retail cuts, greater percentages in intramuscular fat and an $\omega$-3 component linolenic acid, with no difference in cholesterol content, which, altogether, is considered to be more beneficial for human health.

This study was carried out to elucidate the influence of gibberellin soak and seed dressing with Toros wp. on the dehiscence of Eleutherococcus senticossus seeds. $GA_3$ treatment was effective on promoting after-ripening seed of Eleutherococcus senticossus whose concentration was higher until $500\;mg{\cdot}L^{-1}$, after-ripening period became shorter. But rotting percentage increased gradually up above $500\; mg{\cdot}L^{-1}\;GA_3$After all, $300\;mg{\cdot}L^{-1}\;GA_3$ was the most effective treatment for promoting after-ripening seed. Dressing treatment with Toros wp. on seeds reduced the dehiscent rate of E. senticosius. by suppressing activity of fungi living on the endocarp surface of seed.

Purpose: When choosing dressing method to treat skin defect by second degree or higher burn, we have to consider method of rapid epithelization and minimization of pain during the treatment. In this study, we used biologic dressing with cultured allogenic keratinocytes for skin defect due to burn. We followed up the degree of epithelization, the degree of pain, and patient satisfaction. Methods: From June 2003 to June 2006, among the patients with skin defect due to burn, 31 cases with second degree burn(moderate to severe) were selected and biological dressing with cultured allogenic keratinocytes were done. 21 cases did not use cultured allogenic keratinocytes. Most of the patients had second degree burn. We applied cultured allogenic keratinocyte by Kaloderm. For wounds that were not deep enough to effect the dermis, escharectomy was done before applying Kaloderm. After the operation, moist wound site was maintained by dressing with saline gauze for 5 - 7 days. We compared the condition of the wound site before and after applying Keloderm by grading epithelization by standardized percentage scoring scale(1 - 5), and degree of pain and patient satisfaction by visual analogue scale(0 - 10). Results: When cultured allogenic keratinocytes were applied for the same period of time, the mean score of epithelization were $3.29{\pm}0.529$(mean ${\pm}$ S.D.). Without the application, the mean score of epithelization were $2.86{\pm}0.655$(mean ${\pm}$ S.D.). The degree of pain was $7.71{\pm}1.419$(mean ${\pm}$ S.D.) and $2.35{\pm}0.950$(mean ${\pm}$ S.D.) before and after the application, respectively. The patients' satisfaction score was $6.45{\pm}0.850$(mean ${\pm}$ S.D.) and $8.45{\pm}0.961$(mean ${\pm}$ S.D.) before and after the application, respectively. Conclusion: Applying biological dressing with cultured allogenic keratinocyte to skin defect due to second degree burn showed satisfactory results in the degree of the epithelization, degree of pain and patients' satisfaction.
