An experiment was conducted to evaluate the effects of bacteriophage supplementation on egg performance, egg quality, excreta microflora, and moisture content in laying hens. A total of 288 Hy-line brown commercial laying hens (36-wk-old) were randomly allotted to 4 treatments in this 6-wk trial and dietary treatments included: i) CON, basal diet; ii) T1, CON+0.020% bacteriophage; iii) T2, CON+0.035% bacteriophage; iv) T3, CON+0.050% bacteriophage. There were 6 replicates for each treatment with 6 adjacent cages (2 hens/cage). Laying hens in T2 and T3 treatments had higher (p<0.05) egg production than those in CON and T1 treatments during wk 0 to 3. In addition, egg production in T1, T2, and T3 treatments was increased (p<0.05) compared with that in CON treatment during wk 4 to 6. At wk 4 and 5, birds in T2 group had higher (p<0.05) HU than those in CON. In addition, at wk 5 and 6, HU in birds fed T1 and T3 diets was greater (p<0.05) than those fed CON diet. E. coli and Salmonella spp. concentrations in excreta were decreased (p<0.05) by T1, T2, and T3 treatments. However, egg weight, egg shell color, yolk height, yolk color unit, egg shell strength, egg shell thickness, egg gravity, and excreta moisture content were not influenced by dietary treatments during the entire experimental period. In conclusion, bacteriophage supplementation has beneficial effects on egg production, egg albumen, and excreta microflora concentration in laying hens.

Objectives : The present study examines the domestic trend of Chuna treatments on lumbar spinal disorder in Korea. Methods : We investigated the studies on Chuna treatments for lumbar spinal disorder via searching 10 Korean web databases. As a result, 63 research papers were found to be analyzed according to their published year, the titles of journals, the types of study, the techniques of Chuna, the instruments for assessment, the Chuna technique and the number of the treatment trials by the cases of lumbar spinal disorder and ethical approvals. Results : The number of the research papers published tends to increase every year. The studies on Chuna treatments were mainly published in The Journal of Korea CHUNA Manual Medicine for Spine & Nerves. The most frequently adopted technique of Chuna in the examined studies was Cox flexion & distraction technique. Visual analogue scale(VAS), oswestry disability questionnaire(ODI) were used as primary means of assessments. The ethical problems of the examined studies needed to be improved. Conclusion : Reviewing the domestic trend of studies on Chuna treatments for lumbar spinal disorder and examining the strong and weak points of those treatments are essential for the future studies. It is anticipated that this review benefits the future in-depth study on the treatments for Chuna in Korean medicine.
Cocoa pod is among the by-products of cocoa (Theobroma cacao) plantations. The aim of this study was to apply a number of treatments in order to improve nutritional quality of cocoa pod for feeding of ruminants. Cocoa pod was subjected to different treatments, i.e. C (cocoa pod without any treatment or control), CAm (cocoa pod+1.5% urea), CMo (cocoa pod+3% molasses), CRu (cocoa pod+3% rumen content) and CPh (cocoa pod+3% molasses+Phanerochaete chrysosporium inoculum). Analysis of proximate and Van Soest's fiber fraction were performed on the respective treatments. The pods were then subjected to an in vitro digestibility evaluation by incubation in rumen fluid-buffer medium, employing a randomized complete block design (n = 3 replicates). Further, an in vivo evaluation of the pods (35% inclusion level in total mixed ration) was conducted by feeding to young Holstein steers (average body weight of $145{\pm}3.6kg$) with a $5{\times}5$ latin square design arrangement (n = 5 replicates). Each experimental period lasted for 30 d; the first 20 d was for feed adaptation, the next 3 d was for sampling of rumen liquid, and the last 7 d was for measurements of digestibility and N balance. Results revealed that lignin content was reduced significantly when cocoa pod was treated with urea, molasses, rumen content or P. chrysosporium (p<0.01) with the following order of effectiveness: CPh>CAm>CRu>CMo. Among all treatments, CAm and CPh treatments significantly improved the in vitro dry matter and organic matter digestibility (p<0.05) of cocoa pod. Average daily gain of steers receiving CAm or CPh treatment was significantly higher than that of control (p<0.01) with an increase of 105% and 92%, respectively. Such higher daily gain was concomitant with higher N retention and proportion of N retention to N intake in CAm and CPh treatments than those of control (p<0.05). It can be concluded from this study that treatment with either urea or P. chrysosporium is effective in improving the nutritive value of cocoa pod.
This experiment was conducted to determine the effect of replacing limestone by sea shell on digestibility, egg strength and thickness, Ca and P of serum and Ca and P of tibia in layer hens. A total 54 brown layers was assigned to the treatments. There were six layers per replicate with three replicate per treatment. Treatments were layer diet with 7.5% limestone as control, 7.0% limestone and 0.5% sea shell in diet(SS0.5) and 6.5% limestone and 1.0% sea shell in diet(SS1.0). Digestibility of DM was significantly difference between SS0.5 and SS1.0(P〈0.05). Digestibilities of Ca and P were not affected by treatments(P〉0.05), however, SS1.0 tended to increase Ca and P digestibility compared to control. Egg thickness and egg strength were no differences among the treatments(P〉0.05). Differences of initial and finial period on Ca of plasma were significantly affected in the a.m. between SS0.5 and SS1.0(P〈0.05). However, there was no difference in Ca of plasma in the p.m. among the treatments and Ca of plasma in control had a tendency to decrease in the p.m. compared to that of treatments(P〉0.05). Ca of tibia was significantly increased by SS1.0 compared to control(P〈0.05). However, there was no difference in P of tibia among the treatments(P〉0.05). Based on these results, dietary supplemental sea shell mat have a role to improve the egg quality of layer hens.
In the present work the knowledge of dental health as well as dental prosthesis has been studied on the basis of analysis of current dental prosthetic treatments for dental diseases prophylaxis and the final decision for dental prosthetic appliance. The results have been analyzed by the current dental health care and the subjective acknowledgement from 700 people of urban as well as rural inhabitance in our country. The results from the present work have been summarized as following: Depending dental status has been shown worse to be in the cases of divorce and bereavement, age and less educated or jobless. It is also interesting to note that the dental status has shown to be even worse than health status. It has been shown that the dental prosthetic treatments have been mainly caused by the oral disease (62.2%) and depend on the age and the educational level. According to the actual status of dental prosthetic treatments, the fixed partial denture was the most case (78.9%) that increased as divorced, bereavement and as less educated, less income, retired and jobless as well as from urban to rural. As a clinic for the dental prosthetic treatments, dental clinics have been most frequent visited as indicated by 59.6%, then the un-licensed dentist (6.5%), then the hospitals (3.7%), then the public health centers (2.2%). Most of those who are older in age, less educated and jobless have been treated by the un-licensed dentists. In point of view on the cost for dental prosthetic treatments, 93.1% have claimed to be too expensive, in as the divorced and the bereaved, the older age, the less educated and the jobless. About satisfaction of dental prosthetic treatments, 51.4% was satisfied, 39.4% was normal and 9.2% was dissatisfied. Most of people experienced increasing levels of satisfaction as their income increase. Most in the age range of 40-60 have wanted to be insured for the dental prosthetic treatments. It is also interesting to note that the older age and the less educated wanted to apply this kind of insurance.

Pediatric dentistry is differentiated from other fields of dentistry in that it provides comprehensive dental care for children and adolescents. In early days, pediatric dentistry used to be confined to the caries treatment and extraction of primary teeth However, the practice spectrum of pediatric dentistry has broadened to the orthodontic, surgical, esthetic and preventive treatments A survey that contained questions about practice patterns were mailed to 50 pediatric dentists, and 21 surveys were returned. Results were as follows: 1. The average number of patients per week was 82.4, and the average number of treated teeth per patient was 2.35. 2. Preventive treatments comprised 15.7%, restorative treatments 55.7%, endodontic treatments 15.6%, surgical treatments 10.5%, and orthodontic treatments 2.4%. 3. In restorative treatments, amalgam restoration comprised 3.8%, glass ionomer 5.5%, composite resin 63.0%, and stainless steel crown 27.7%.

This experiment was conducted to examine the effects on the composition and rumen degradation in sacco of rice straw treated with animal urine (1 l of 2.9 g N/kg DM straw) and urea plus calcium hydroxide (2% urea plus 0.5% $Ca(OH)_2$/kg DM straw) as a cheap and relatively safe alternative for ammonia (3% ammonia solution/kg DM straw). Mold occurred in urine treated straw, but other treatments were apparently mold-free. All treatments significantly (p<0.05) increased CP content in the straw compared with untreated one. Ammonia-treated straw contained CP at about twice that in urine or urea-calcium hydroxide treated straw. NDF and hemicellulose contents decreased significantly (p<0.05) in all treatments, while ADF and cellulose showed no differences compared with untreated straw. The degradable fraction of DM, CP, NDF, hemicellulose and cellulose was significantly (p<0.05) increased for ammonia and urea-calcium hydroxide treatments than for urine treated or untreated straw except for CP of urine treated straw. Chemical treatment of rice straw increased the readily degradable fraction of CP, while it decreased the slowly degradable fraction for urine or urea-calcium hydroxide treated rice straw. The degradation rate of hemicellulose was significantly (p<0.05) increased for ammonia and urea-calcium hydroxide treatments compared to urine treated or untreated straw. However, no effect on cellulose degradation rate was found by any of the treatments. There was no improvement in the degradation kinetics caused by the urine treatment despite the improvement of the chemical composition. Although the improvement in rumen degradability was less in the urea-calcium hydroxide treatment than in the ammonia treatment, its use may be more desirable because it is less expensive to obtain, less hazardous nature, and readily available. For further improvement it is necessary to investigate the supplementation of slowly degradable nitrogen to ureacalcium hydroxide treated rice straw diet.
This paper gives an overview of the availability, nutritive quality, and possible strategies to improve the utilization of rice straw as a feed ingredient for ruminants. Approximately 80% of the rice in the world is grown by small-scale farmers in developing countries, including South East Asia. The large amount of rice straw as a by-product of the rice production is mainly used as a source of feed for ruminant livestock. Rice straw is rich in polysaccharides and has a high lignin and silica content, limiting voluntary intake and reducing degradability by ruminal microorganisms. Several methods to improve the utilization of rice straw by ruminants have been investigated in the past. However, some physical treatments are not practical because of the requirement for machinery or treatments are not economical feasible for the farmers. Chemical treatments, such as NaOH, $NH_3$ or urea, currently seem to be more practical for onfarm use. Alternative treatments to improve the nutritive value of rice straw are the use of ligninolytic fungi (white-rot fungi), with their extracellular ligninolytic enzymes, or specific enzymes degrading cellulose and/or hemicellulose. The use of fungi or enzyme treatments is expected to be a more practical and environmental-friendly approach for enhancing the nutritive value of rice straw and can be costeffective in the future. Using fungi and enzymes might be combined with the more classical chemical or physical treatments. However, available data on using fungi and enzymes for improving the quality of rice straw are relatively scarce.

One hundred and twenty nine primiparous sows were used to determine the effects of alternative processing procedures and feeding systems on the nutritional value of sorghum grain-based diets for lactating sows. Treatments were a ground sorghum control, steam-flaked sorghum and extruded sorghum fed in meal form and the ground sorghum control given as pellets or gruel (1:1 ratio of water and feed on a volume:volume basis). Average daily feed intake was greater for sows fed pelleted and gruel diet forms than sow fed the diets with steam-flaked and extruded sorghum (p<0.04). However, no differences occurred in sow weight or backfat losses among the treatments (p>0.14). Number of pigs weaned and livability rates were similar among treatments except that steam-flaked sorghum supported greater litter weight gains than extruded sorghum (p<0.02). Apparent digestibilities of DM, N and GE in sows fed steam-flaked and extruded sorghum were greater (p<0.001) than in sows fed pelleted or gruel diets. Of the various treatments, sows fed extruded sorghum tended to have the highest digestibilities of DM, N and GE, and lowest excretions of DM and N in the faeces. Severity of ulceration was not significantly affected by treatments (p>0.35), but keratinization was greatest for sows fed extruded sorghum (p<0.01). In conclusion, the alternative processing methods (steam-flaking and extrusion) and feeding system (pellets and gruel) had little effect on sow and litter performance. However, nutrient digestibilities were improved for all treatments that involved heating (steam flaking, extrusion and pelleting) and, thus, these treatments resulted in less fecal excretion of DM and N.
To investigate the effects of Lactobacillus curvatus and Leuconostoc mesenteroides on suan cai (pickled Chinese cabbage) fermentation, L. curvatus and/or Ln. mesenteroides were inoculated into suan cai. Physicochemical indexes were measured, and the microbial dynamics during the fermentation were analyzed by Illumina MiSeq sequencing and quantitative polymerase chain reaction (qPCR). The results showed that inoculation with lactic acid bacteria (LAB) lowered the pH of the fermentation system more rapidly. The decrease in water-soluble carbohydrates in the inoculated treatments occurred more rapidly than in the control. The LAB counts in the control were lower than in other inoculated treatments during the first 12 days of fermentation. According to the Illumina MiSeq sequencing analyses, Firmicutes, Proteobacteria, Bacteroidetes, Actinobacteria, Cyanobacteria, Fusobacteria, and Verrucomicrobia were present in the fermentations, along with other unclassified bacteria. Generally, Firmicutes was predominant during the fermentation in all treatments. At the genus level, 16 genera were detected. The relative abundance of Lactobacillus in all inoculated treatments was higher than in the control. The relative abundance of Lactobacillus in the treatments containing L. curvatus was higher than in the Ln. mesenteroides-only treatment. The relative abundance of Leuconostoc in the Ln. mesenteroides-containing treatments increased continuously throughout the fermentation. Leuconostoc was highest in the Ln. mesenteroides-only treatment. According to the qPCR results, L. curvatus and/or Ln. mesenteroides inoculations could effectively inhabit the fermentation system. L. curvatus dominated the fermentation in the inoculated treatments.
