A total of 11,395 animals were impounded in shelters in Seoul in 2013. The Animal Protection Division of the Seoul metropolitan government has annual contracts with local veterinary associations as well as Korean animal rescue and management organizations for providing shelter to animals, and collects monthly statistics from these groups. In 2013, the collected intake and outcome data for 25 districts were reviewed to analyze shelter capacity in terms of housing capacity (monthly daily average intake, required holding capacity, and adoption-driven capacity), staff capacity (staff hours required for daily care), and live release rate. Seasonal variations in the monthly daily average intake were observed, indicating that management of these shelters requires various strategies. This study was performed to analyze and interpret meaningful statistics for improving the efficiency of animal shelters in Seoul. However, inconsistent collection of animal statistics limited data compilation. Creation of a basic animal statistics matrix with reference to well-designed matrices from recognized professional animal shelters is essential. These complied statistical data will help plan for future animal shelter needs in Seoul.

Since the industrialization of swine production in the late 1900s, swine farms in the United States, as well as in Europe, have largely become consolidated. Pig farms became larger in size but fewer in number, with 91% of market pigs being produced by large operations with 5,000 or more pigs on-site in the US, and only 3% of the total utilized agricultural land representing organic farming. Such change in the market made it difficult for small farmers to stay competitive, forcing them to find alternative ways to reduce the cost of production and increase profit using the outdoor production system. In contrast to the indoor confinement system, outdoor production system uses pasture-based units and/or deep-bedded hoop structures that promote animal welfare and environmental sustainability with a lower capital investment. In accord with the growing concern for animal and environmental welfare and food safety by the consumers, small farmers practicing an outdoor production system are seeing increased opportunities for marketing their products in the pork niche market. Unlike the general belief that the reproductive and growth performance measures of the outdoor sows and piglets are poorer in comparison with the animals reared indoors, studies showed that there was no significant difference in the performance measures, and some traits were even better in outdoor animals. Improved reproductive and production traits can increase the sustainability of outdoor farming. Present study reviewed the recent studies comparing the performance measures, meat quality and health of indoor and outdoor animals, as well as the efforts to improve the outdoor production system through changes in management such as hut types and breed of animals.

This paper aims to critically analyse and synthesise existing knowledge concerning the use of environmental enrichment and its effect on behavior, physiology and performance of pigs housed in intensive production systems. The objective is also to provide clarity as to what constitutes successful enrichment and recommend when and how enrichment should be used. Environmental enrichment is usually understood as an attempt to improve animal welfare and to a lesser extent, performance. Common enrichment objects used are straw bedding, suspended ropes and wood shavings, toys, rubber tubings, colored plastic keys, table tennis balls, chains and strings. These substrates need to be chewable, deformable, destructible and ingestible. For enrichment to be successful four goals are essential. Firstly, enrichment should increase the number and range of normal behaviors; secondly, it should prevent the phenomenon of anomalous behaviors or reduce their frequency; thirdly, it should increase positive use of the environment such as space and fourthly it should increase the ability of the animals to deal with behavioral and physiological challenges. The performance, behavior and physiology of pigs in enriched environments is similar or in some cases slightly better when compared with barren environments. In studies where there was no improvement, it should be borne in mind that enriching the environment may not always be practical and yield positive results due to factors such as type of enrichment substrates, duration of provision and type of enrichment used. The review also identifies possible areas that still need further research, especially in understanding the role of enrichment, novelty, breed differences and other enrichment alternatives.

During the last 20 years, transgenic animal technology has provided revolutionary new opportunities in many aspects of agriculture and biotechnology. Several gene delivery systems including pronuclear injection, retroviral vectors, sperm vectors, and somatic cell cloning have developed for making transgenic animals. In the future major improvements in transgenic animal generation will be mainly covered by somatic cell cloning technology. Many factors affecting integration frequency and expression of the transgenes should be overcome to facilitate the industrial applications of transgenic technology. Transgenic animal technology has settled down in some areas of the biotechnology, especially the mass production of valuable human proteins and xenotransplantation. In the 21st century animal biotechnology will further contribute to welfare of human being.

Two experiments were conducted with broiler chickens to determine cage floor preferences, the strength of preference for a particular floor type and to evaluate the effect of rearing broilers on the preferred cage floor on productivity. In experiment 1, chicks when offered free access to either wire (WF) or plastic (PF) mesh flooring, preferred the former. However, when the perferred floor type (WF) was illuminated at 800 lux, birds spent longer time on PF. Also provision of incandescent lamps at PF resulted in broilers spending significantly longer period on WF. In experiment 2, while floor type had no effect on growth of female chicks throughout the duration of study, male chicks grown on PF were heavier than their WF counterparts on Days 21, 28, 35 and 42. Neither livability, nor incidence of breast blisters and leg deformities was affected by floor type.

A new species of bryozoan, Bicellariella fragilis n. sp. is reported from Jejudo Island, Korea. It was collected at Munseom I. and Supseom I. off Seogwipo city by the fishing net and SCUBA diving from 1978 to 2009. The new species has characteristics of four to five dorso-distal spines and two proximal spines, whereas ten to twelve spines of B. sinica are not separated into two groups of the distal and proximal ones. And this species shows the difference from B. levinseni in having no avicularium.

Rapid urbanization and social development have brought about changes in family structure. In urbanized areas, recently the number of dogs that are a majority of companion animals has increased significantly in Korea. Consequently, a lot of friction between the general public who are not fond of dogs and dog owners in public places such as parks has been happening. A lot of countries that are taking a lead role in animal welfare have built dog parks that the general public and dogs can enjoy together. This research starts with the realization that the concept of 'dog park' needs to be introduced in Korea as more and more Koreans own dogs and other pets. This research aims to provide guidance for dog park planning by drawing planning items and analyzing the needs of each item. Total 56 planning items including dog zone, dog playground, and dog training facility, are drawn in this research. There are differences in the needs according to sex, age and the amount of time they spent with their dogs, however overall there is the highest needs in separated area for dogs in parks.

Unlike Europe (particularly, Italy and Spain), where a number of studies have been conducted on the stressful effects of transport on rabbit welfare, few studies have been conducted on transportation of rabbits under hot, humid tropical conditions experienced in countries like Malaysia. We studied the effects of transportation in hot humid tropical conditions of Malaysia on physiometabolic changes in New Zealand white rabbits. Eighty experimental animals were divided into two groups of 40 bucks each and transported for either 3 or 1 h. Transportation caused a significant upsurge of aspartate aminotransferase, alanine aminotransferase and creatine kinase activities (p<0.001) though did not significantly affect lactate dehydrogenase (LDH) activity (p = 0.0706). Both transportation periods caused elevation in plasma glucose levels, lactic acidosis and dehydration as evidenced through elevated packed cell volume and plasma protein concentration. It was concluded that regardless of the duration, transport of rabbits under hot humid tropical conditions, resulted in heat distress since the rabbits showed hyperglycemia, hypercalcemia, lactacidemia, lymphocytopenia, dehydration and increase in blood enzyme activities.

동물복지의 관심고조는 전 세계적인 동향이며 최근 국내 소비자들의 복지는 반려동물에서 경제동물인 가축으로 확산되고 있다. 환경보조물은 동물복지수준 강화에 유용한 수단으로 활용되고 있으나 임신돈에서는 관련 연구는 제한적이다. 따라서, 본 연구는 환경보조물이 임신모돈의 생산성 및 행동특성에 미치는 영향을 구명하고자 실시하였다. 시험동물은 30두의 임신돈(랜드레이스)를 준비하였고, 완전임의배치법에 의거하여 3개 처리구(대조구; T1, 플라스틱 소재 놀이기구; T2, 볏짚)에 처리구당 10두씩 배치하였다. 사양시험은 임신 28-105일령동안이며 볏짚과 놀이기구는 시험돈방($11.6{\times}6.0m$) 중앙에 배치하였다. 시험 종료일에 체중 및 등지방두께를 측정하였으며 혈중 코티졸 농도를 분석하였다. 행동특성 분석을 위해 임신 91일령에 행동패턴을 24시간 촬영하였고 행동특성을 분석하였다. 시작 및 종료체중은 대조구 및 처리구간 차이를 나타내지 않았다. 등지방두께는 대조구보다 T2에서 감소하였다(C, 16.56mm vs. T2, 15.73mm; p>0.05). 총산자수, 실산자수는 처리구간 차이가 없다. 사산수는 T1 및 T2에서 대조구보다 감소하였다(1.00 and 0.63 vs. 1.50두; p>0.05). 분만폐사율은 사산수와 유사한 경향을 보였다(C, 8.68%; T1, 6.86%; T2, 3.40%). 혈중 코티졸은 대조구 및 처리구간 차이가 없다. 섭취행동은 T2에서 대조구 및 T1 처리구보다 감소하였다(1.81 vs. 9.68 and 6.99%; p<0.05). 놀이 및 파헤치기 행동은 각각 T1와 T2 처리구에서만 확인되었다(p<0.05). 반면에 사육시설에 문지르기 행동은 대조구에서만 관촬되었다(p<0.05). 이러한 결과는 환경보조물 제공이 임신돈의 생산성에 부정적인 영향을 미치지 않으면서 돼지의 행동특성은 복지향상에 도움이 될 것으로 판단된다.
