Enrofloxacin is one of the normally used flouroquinolones in mammalian and fish but its withdrawal time and studies were remain obscure. The residual contents of enrofloxacin in fish muscle were analyzed by using HPLC-FLD. More than 0.1 mg/kg of ENR was detected in muscle tissues and the residues were found over 1 year after treatment. The concentration of ENR in Paralichthys olivaceus was not affected by water temperature and lasted for an extended amount of time. The spike recoveries of ENR in the muscle tissue ranged from 78% to 85%. From this results, we need the prescription by veterinarian or aquatic organism disease inspector in ENR usage to assure safety of fish. Future research is required to determine the recommendation dose of ENR for side effects and safety.

The present study was to investigate the effect of the transition from conventional to organic dairy farming on the antimicrobial resistant pattern of pathogens in milk. A farm with tie-stall management, with an average herd size of 20 milking cows, was selected based on the owner' willingness to accept, for at least 6 months, the highly restricted protocol developed in this study. Comparisons of bacterial isolates and antimicrobial susceptibilities before changing to an organic farm system (BEFORE) and for 6 months after (AFTER) operating the experimental organic farm system were performed by Fisher's Exact Chi-square tests. Significant levels were defined at p<0.05. During the AFTER period, average frequency of antibiotic treatment was decreased from more than 3 cases/month to less than 1 case/month during which the antibiotic use was authorized only by the veterinarian. In total, 92 and 70 quarter milk samples from 24 and 18 cows during BEFORE and AFTER, respectively, were included in the study. Overall, isolates ranged from a non-resistant level for cephazolin to a very high resistant level to streptomycin (64.71% to 95.45%). Percentages of antimicrobial resistant isolates during BEFORE were significantly higher than during AFTER for ampicillin (43.48% and 5.88%, respectively) and streptomycin (95.45% and 64.71%, respectively). In conclusion, percentages of antimicrobial resistant isolates were decreased after 6 months of operating as an organic farm system.

The paper discusses a novel educational initiative in e-commerce pedagogy where students work on an e-government project. The paper describes a two-semester joint e-government project conducted by the town of Amherst, NY, and the State University of New York at Buffalo. During the first semester, students in a graduate e-commerce course in the School of Management were instructed to identify and analyze management issues valuable for small or middle size local government. In the second semster graduate students from the Department of Computer Science and Engineering designed and implemented prototypes of three e-government portals: an on-line action site for governmental procurement (E-Procurement), a portal for reservation of community recreation facilities (E-Recreation), and a portal for online dog registration (E-DogRegistration) combining a central registry of dog owners with distributed veterinarian databases. The objective of this initiative is twofold. First, it saves the local government resources by eliminating duplication of services and by using students as developers. Second, it provides students with real life hands-on experience. The paper discusses both the technical issues involved in the implementation of the project, and the management issues that need to be taken into account to enhance the e-commerce experience for the ordinary citizen and local governments.

Three dogs were presented with signs of recurrence of coughing, dyspnea and difficulty of barking after endotracheal stent placement. On the basis of history taking, physical examination, laboratory tests and radiography, complications of endotracheal stent were suspected. Dog 1 had unfitted stent diameter (stent diameter is larger than tracheal diameter) and getting disentangled of proximal tracheal stent wire. Dog 2 was suspected a foreign body reaction. Dog 3 had the migration of stent caudally. Based on these cases, the veterinarian should accurately evaluate the indicated patients before endotracheal stent and has to select the appropriate stent (diameter, length and location) to prevent complications after endotracheal stent and concern the regular follow-ups to assure proper endotracheal stent placement.

This study was designed to evaluate the beekeeper's consciousness for diagnosis and treatment on a disease of honey-bee in Daejeon and Jeollanamdo in Korea. The questionnaire consisted of 14 questions. Of 231 randomly selected respondents between February and May 2010, 47.6% was consult a 'club (colleague)', 89.2% treated a 'doctoring oneself', 84.4% was recognize a bee as 'domestic animal', 77.5% was not recognize a veterinarian as field of treatment, 38.5% was acquire know-how by a beekeeper. Therefore these results suggest that the beekeepers are relying a lot on individuals experience for the diagnosis and treatment on the disease of honey-bee, the apiculture techniques was gained much by oneself. Korean beekeeping association was played a role as well, but related-university, agriculture research & extension services and veterinary service laboratory was not played a role in the country.

Footpad dermatitis (FPD) can be considered as a threat for poultry production due to it causes losses due to condemnation in slaughterhouse. The prevalence and the severity of FPD in broiler breeders increase over time with development of poultry industry. The condition is produced by multifactorial including include drinker design and management, diet composition, house (temperature and humidity levels), litter (type, quality, and quantity) and gut health. Bacterial infections can be associated. FPD lesions can develop in less than a week. FPD is a variable size of inflammatory lesion of the footpad in commercial poultry characterized by necrotic lesions on the plantar surface of the footpad of poultry. These lesions can be exposed after removal of fecal mass and litter stuck on it. There are considerable and numerous interactions between the environment and the genetic traits. Prevention depends mainly on improvement of litter condition. Genetic selection against footpad dermatitis must be contributed to reduce pain and suffering for particular bird experiencing contact dermatitis as well as to avoid economic losses. The objective of this review is to collect different literature written about FPD to be available to students, researchers and veterinarian in poultry practical.

The animal welfare issues in cattle breeding include breeding environment, elimination, and castration. Among these, castration is unavoidable because it decreases cattle aggressiveness, improves meat quality, and enhances feed efficiency. In this study, the degree of stress associated with various methods of castration treatment was investigated for animal welfare in Hanwoo breeding. Cortisol levels dramatically increased right after castration in both the SoF and SoV groups. However, the increase in the SoF group was significantly (P<0.05) higher than that in the SoV group, and the range of decrease was also smaller. Among the behavioral characteristics, standing was significantly (P<0.05) higher in the SoV ($374.93{\pm}21.51$) and SoF ($379.93{\pm}21.30$) groups based on the behavioral time (min/12 hours) compared to that in the NC group ($359.37{\pm}19.69$). The SoF and SoV groups did not show any significant (P<0.05) difference. In terms of behavioral frequency, the NC group demonstrated a significantly (P<0.05) high frequency of drinking, self-grooming, scratching, and rubbing, and a significantly (P<0.05) less frequency of fighting behavior. The feeding time significantly (P<0.05) decreased in the SoV and SoF groups, and their frequencies of pairwise grooming were significantly (P<0.05) less. Based on the results, the cattle experienced less stress during castration by a veterinarian than during treatment using a move-stop.

Foaling is a process of giving birth to foal which is prompt and forceful event in equine breeding. Dystocia is declared when 2nd stage of parturition exceeds from 20 min without fetal movements in mare. Dystocia is very challenging situation for both mare and veterinarian. Survivability of mare and foal, and subsequent fertility of mare depends on efficient management. Therefore, the current report described a rare case of wry neck (torticollis or unilateral bent neck) resulted in dystocia, that was efficiently resolved by partial fetotomy and repulsion technique in mare under field conditions. Intensive post operative care was performed to avoid infection and to achieve fertility subsequently.
