  • This study introduces a prototype for a virtual zoo initiative, aimed at optimizing resource utilization and minimizing animal displacement from their natural habitats. The prototype features a thoughtfully developed three-dimensional representation of an emperor penguin, with animations designed to emulate real-life behaviors. An investigation into file format distinctions for scientific research, encompassing Wavefront(OBJ), Collada(DAE), and Filmbox(FBX) formats, was conducted. The research utilized the Hololens 2 device for visualization, Unity for environment development, Blender for modeling, and C# for programming, with deployment facilitated through Visual Studio 2019 and the Mixed Reality Toolkit. Empirical examination revealed the OBJ format's suitability for simple geometric shapes, while DAE and FBX formats were preferred for intricate models and animations. DAE files offer detailed preservation of object structure and animations albeit with larger file sizes, whereas FBX files provide compactness but may face scalability constraints due to extensive data integration. This investigation underscores the potential of virtual zoos for conservation and education, advocating for further exploration and context-specific implementation.

  • Sarcocystis sp. infection was investigated in 20 necropsied captive wild mammals and 20 birds in 2 petting zoos in Malaysia. The gross post-mortem lesions in mammals showed marbling of the liver with uniform congestion of the intestine, and for birds, there was atrophy of the sternal muscles with hemorrhage and edema of the lungs in 2 birds. Naked eye examination was used for detection of macroscopic sarcocysts, and muscle squash for microscopic type. Only microscopically visible cysts were detected in 8 animals and species identification was not possible. Histological examination of the sections of infected skeletal muscles showed more than 5 sarcocysts in each specimen. No leukocytic infiltration was seen in affected organs. The shape of the cysts was elongated or Circular, and the mean size reached $254{\times}24.5{\mu}m$ and the thickness of the wall up to $2.5{\mu}m$. Two stages were recognized in the cysts, the peripheral metrocytes and large numbers of crescent shaped merozoites. Out of 40 animals examined, 3 mammals and 5 birds were positive (20%). The infection rate was 15% and 25% in mammals and birds, respectively. Regarding the organs, the infection rate was 50% in the skeletal muscles followed by tongue and heart (37.5%), diaphragm (25%), and esophagus (12.5%). Further ultrastructural studies are required to identify the species of Sarcocystis that infect captive wild animals and their possible role in zoonosis.

  • Seven years old male lion in Everland Zoo has three fractured canine tooth. To avoid the risk of a possible fracture with pulp exposure after restroration of largest abration defects, endodontic therapy was performed. The pulp chamber was filled with calcium hydroxide, zinc oxide cement and gutta percha. We also installed the Crown prosthesis was installed in fractured canine tooth to protect the tooth and to improve the cosmetics and function of the tooth. The lion could eat in one day and there were no any signs of dental problem. It is the obvious prophylactic procedure for wild animal is the inclusion of an oral examination at every opportunity to handle the animal. It is considered that crown prosthesis after endodontic therapy was useful for maintaining normal physiological function and for provention of additional fracture or complication.

  • Flehmen is well-known response which often occurs during the process of courtship in most mammals. Recent studies with domestic ruminants suggest that the flehmen may be involved in the mechanism of transferring some pheromonal substances to vomeronasal organ. Thus, variety of its significancehas been supposed, besides that male animals may use it for estrus detection. In this experiment, 8 male, 3 female and3 castrated goats of Saanen and its hybrid were used to ascertain whether urine from alien species can induce flehmen as that from same species. Urine was collected from twenty species consisting of 15 mammals, 3 birds and 2 reptiles and frozen until use. Mostly urine was sprayed to the nose of goats, but some coagulated ones were sniffed. Duration of flehmen was scored to four ranks as 0, 1-19, 20-39 and >40 sec. Each urine sample induced the response in any goats. However, much difference in the in tensity was found between the samples and according to the reproductive state of the receptor goats. Although individual difference was manifest, male goats generally showed more intense response than did female. Castrated goats showed the intermediate pattern. Administration of antiandrogen to the male goat tended to reduce the response. The results indicate that flehmen in the goat could occur for the urine of alien species as that of same species and the androgen may be one of the factors regulating the response.

  • 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.

  • Animal welfare has become a prominent concern around the world so that the laws and guidelines of animal welfare are being strengthened in many countries including the EU. In Korea, it is required to supplement animal welfare standards because social awareness of animal welfare has changed. This study was conducted to compare broiler welfare certification standards and improve the quality of practice. We found that broiler welfare certification standards differ among countries according to environmental and managemental differences. Standards for stocking density and perch which is considered more important for poultry welfare are similar, but there is a little difference in feed, water, litter and lighting. Therefore, we assumed that theses are able to revise standards taking into account the environment and suggested that the broiler welfare certification standard will serve as a more useful criterion if breeding conditions in Korea are considered.

  • Objective: Long chain n-3 polyunsaturated fatty acids (PUFA) exert positive effects on human health. The long chain n-3 PUFA of pork can be increased by adding fish oil to the diet. Due to the cost and availability of fish oil an alternative source must be found. Methods: This study evaluated the effect of five dietary oils on meat quality, fatty acid composition and lipid stability. The five diets contained 1% palm oil (Control), 1% soya oil, 1% linseed oil, 1% fish oil, and 1% Echium oil, respectively. The trial consisted of 60 gilts, randomly allocated to five groups. Results: All color parameters, extractable fat content, fat free dry matter, and moisture content of the m. longissimus muscle were unaffected by dietary treatment. Consumers and a trained sensory panel could not detect a difference between the control samples and the Echium oil sample during sensory analysis. Samples containing higher levels of PUFA (soya, linseed, fish, and Echium oil) had higher levels of primary and secondary lipid oxidation products after refrigerated and frozen storage. However, these values were still well below the threshold value where off flavors can be detected. The Echium oil treatment had significantly higher levels of long chain PUFA than the linseed oil treatment, but it was still significantly lower than that of the fish oil treatment. Conclusion: Echium oil supplementation did not increase the levels of n-3 to the same extent as fish oil did. The result did however suggest that Echium oil can be used in pig diets to improve muscle long chain n-3 fatty acid content without any adverse effects on meat quality when compared to linseed, soya, and palm oil.

  • This study was performed to development the alternative farrowing pen (AFP) and to investigate performance and behavior of lactating sows and their litter. A total of 64 multiparous sows were randomly divided into two groups and were allocated to farrowing crates (FCs) and AFPs. The AFPs contained a crate and support bars that could be folded to provide the sows with extra space on day 5 postpartum. Behavior was recorded by charge-coupled device cameras and digital video recorders, and the data were scanned every 2 min to obtain an instantaneous behavioral sample. Farrowing systems did not affect feed intake, back-fat thickness, litter size and piglet weight at birth and weaning (p > 0.05). In addition, there were no differences in the number of crushed piglets between the two farrowing systems (p > 0.05). However, the weaning-to-estrus interval was shorter in the sows of the AFPs than in thous of the FCs (p < 0.05). The sows spent most of their time lying down during the lactating period, at about 80% lateral recumbency and 10%-15% ventral recumbency. The only significant differences were in the feeding and drinking behavior between sows in the two farrowing systems (p < 0.05). The FC sows displayed more feeding and drinking behavior than the AFP sows, especially in the late lactating period (p < 0.05). Piglets in the FCs tended to spend more time walking than piglets in the AFPs (p < 0.05), whereas there were no differences in suckling and lying behavior between piglets in the two farrowing systems (p > 0.05). It is concluded that the AFPs with temporary crating until day 4 postpartum did not negatively affect performance and crushed piglet compared with the FCs. It also may improve animal welfare by allowing sows to move and turn around during the lactating period. Further research is needed to find suitable housing designs to enhance productivity and animal welfare.
