Problems with maintaining service and equipment in some developing countries suggest that the rumen bag technique may be more appropriate for the determination of plant dry matter digestibility. The technique has been adapted for use in goats in the 16-25 kg liveweight range. Reliable results were obtained for animals maintained under shelter in cages and fed on a mixed legume/grass diet. The results showed that up to 7 bags containing dried and ground (2 mm screen) plant samples (1-3 g) could be satisfactorily used in each goat. The digestibility of the legumes studied did not increase with incubation times over 48 hours, but there was an increase in the digestibility of grasses. However an incubation time of 48 hours was adapted for both legumes and grasses as it allowed more efficient work scheduling for large numbers of samples while still giving acceptable comparisons between species. Losses of material from the bags during a 6 hour soaking in water were 2-9% as fine solids and 14-21% in solution. In the method finally adapted the disappearance was measured for plant samples that were placed in Dacron mesh bags ($7{\times}14cm$, 44 micron) and 6 bags suspended in the rumen of each sheep for 48 hours.

Background: Heartworm infection in dogs is caused by Dirofilaria immitis and common in shelter animals and outdoors dogs. Caval syndrome can develop with severe infection and physical heartworm removal is essential with heartworm burdens. In this study, we used an improved transvenous heartworm extraction brush, which was expected to cause less cardiovascular damage and allow easier manipulation. Objectives: This study aims to evaluate efficacy of this improved transvenous heartworm extraction brush. Methods: The brush was designed to improve upon the limitations of the previous brush-type devices. The brush was made of a polyvinyl chloride tube and threads of polyamides or polyglyconates. Metal material was inserted at the front tip for easy visualization under fluoroscopy. The eight dogs diagnosed with caval syndrome with large numbers of heartworms and pulmonary hypertension were used in this study. The removal procedure began with the dissection of the subcutaneous tissue around the right jugular vein. The device was inserted through the jugular vein. After insertion, the tube was rotated to catch the heartworms and extracted with the heartworms hanging on the threads. The procedure was repeated several times. Lastly, jugular vein and skin sutures were made. Adulticidal therapy was administered after heartworm removal. Results: The mean number of removed heartworms was 10.5 ± 4.24 and mean number of remaining heartworms was 0.63 ± 1.06. Total procedure time was 72.63 ± 51.36. Except for three cases, heartworms were not detected on ultrasonography after the procedure. No procedure-related side effects were observed within the 1- to 2-mon. Conclusions: An improved transvenous heartworm extraction brush is efficient for heartworm removal in dogs with caval syndrome.

Pagurus undosus and Pagurus parvispina, collected from the East Sea by fishery trap, are newly recorded from Korean waters. Pagurus undosus is distinguished from other hermit crab by its right cheliped slightly elevated medially, and with broad ridge formed by deep depressions mesial and lateral to midline. Pagurus parvispina is distinguished from other hermit crab by its right cheliped covered with large spine and long tufts of setae. These species live in cold water areas and their geographical distribution is extended southwardly by the present study. A specimen of the former species, P. undosus, was found living in a shelter formed by a sponge, similar to that observed in Pagurus pectinatus. Descriptions and figures of these two species are provided in this paper. Currently, 27 species of the genus Pagurus are recorded in Korean fauna.

BACKGROUND: The purpose of this study was to evaluate ecological function of small-scale pond and movement characteristics of mudfish (Misgurnus mizolepis) during midsummer drainage period. METHODS AND RESULTS: In situ experiments were performed in the paddy field with mudfish under the condition of midsummer drainage from 13 July to 29 July 2010. The mudfish used in this experiment is approximately 1,000 individuals with a cut tail. Mudfishs were released in the rice field before midsummer drainage and caught again in the small-scale pond and the paddy field after midsummer drainage. Results showed that the abundance of mudfish was higher in drainage canal than small-scale pond at the early stage of midsummer drainage, because flow was formed toward the drainage canal. In that time, 3% of the total marked mudfish were captured at outlet of drainage canal. As the paddy was drying, 5% of total marked mudfish moved to the small-scale pond during midsummer drainage period. Contrary to the general hypothesis, the marked mudfish was not found in holes in paddy field.of total caught in the small-scale pond ingested mainly animal prey, and it's frequency of empcy stomach was 10%.oOn the other hand, all m total collected in the paddy field showed empcy stomach. It was apparent from the experiment that m total are eeldng normally in the small-scale pond, while m total are not eat properly in paddy field. CONCLUSION(s): As the paddy was drying, mudfish moved to the small-scale pond during midsummer drainage period but mudfish was not found in holes in paddy field. It can be concluded that small-scale provides a shelter and prey to mudfish in the midsummer drainage period.

The present study was undertaken to evaluate the effect of flushing of ewes with concentrate pellets just before the mating season on their nutrient utilization and reproductive performance on farms. Forty-eight Malpura ewes, 1-5 years old were randomly divided into 2 groups of 24 each (G1and G2). Ewes in both the groups were grazed on natural rangeland from 07.00 to 18.00 hr followed by night shelter in animal shed. G1 ewes were maintained on sole grazing while G2 ewes, in addition to grazing, received concentrate pellets at the rate of 1.5% of their body weight. The mean biomass yield of the community rangeland was 0.46 ton DM/hectare. The intakes of DM (g/kg $W^{0.75}$), DCP (g/kg $W^{0.75}$) and ME (MJ/kg $W^{0.75}$) were higher (p<0.01) in G2 as compared to that of G1 being 86.5, 10.2 and 1.15 and 57.5, 4.7 and 0.75, respectively. The digestibility of DM, OM, CP, NDF and hemicellulose were also higher (p<0.01) in G2 as compared to that of G1 being 57.2, 76.7, 78.9, 51.9 and 81.6 and 50.8, 68.7, 68.4, 45.4 and 74.4, respectively. The conception rate was higher (79.2%) in flushed ewes as compared to that of non-flushed (66.7%). Five of the pregnant ewes died and another 5 aborted in G1 while in G2, 5 ewes aborted with no mortality. The lambing was higher (73.7%) in G2 than that in G1 (37.5%). The birth weight of lambs was higher (p<0.05) in G2 (3.47 kg) than that in G1 (2.95 kg). Further, the birth weight of male lambs was higher (3.28) than that of female lambs (3.14). It is concluded that the biomass yield of the community rangeland in semi-arid region of India is low and insufficient to meet the nutrient requirement of ewes prior to mating season. However, concentrate supplementation at the rate of 1.5% of body weight to ewes during this critical stage enhanced their plane of nutrition, reproductive performance, body condition and birth weights of lambs.

About 350 shelters nationwide go through about 100,000 organic animals every year. If you are not adopted by the adoption candidate, you will be euthanized in just one out of every fourteen days after entering the shelter. Therefore, in order to prevent the occurrence of organic animals, it is necessary to register the companion animal easily and to register the inscription to manage the history. In this paper, we propose a local technician who can describe feature points in inscription images to develop recognition technology through inscription, which can distinguish companion animals such as human fingerprints.

This study aimed to evaluate the effects of four types of environmental enrichment on the improvement of companion dogs' behavioral problems due to separation anxiety. A total of 21 dogs of various breeds were included in the study. Data were collected to investigate the behaviors associated with anxiety in dogs, including vocalization, elimination, escape attempts, and destructiveness. A first stage, in which the dog and owner were together (P0), lasted 15 min, and a second stage, in which the dog and owner were separated (P1), lasted 15 min. After the dog and owner were separated (P1), the third stage (P2), during which the environment was enriched, lasted 20 min, and the fourth stage, following environment enrichment (P3), lasted 15 min. The results of the study indicated that compared to P0, the frequency of problematic behavior was highest during the 15 min following separation from the owner (P1). Following environmental enrichment, the average frequency of problematic behaviors in P2 decreased (P < 0.001) compared to P1. Environmental enrichment can also be used appropriately in the case of companion dogs, including shelter dogs or experimental dogs that use a limited kennel, and is a particularly effective means of improving the quality of life of dogs.

This study was conducted to examine the characteristics of flowering and fruiting in Nelumbo pentapetala 'Yellow Bird'. Lotus rhizomes were planted in pot (70 cm in length and 71 cm in width) on April 18, 2008, and grown under rain shelter condition at a private farm in Muan-gun, Jeonnam. Ninety percent of the lotus plants were bloomed as two flowers per a plant, and the others were one flower. The first flowers were bloomed in the middle or late July, and the second flowers in the early August. Flower stalks were formed between eighth and tenth internodes in the main rhizome. Nelumbo pentapetala 'Yellow Bird' had light yellow flowers, 12 cm in length and 13 cm in width. Lotus plants of 21.4% were not bloomed, resulting from the insufficient securing of internodes in the main rhizome and the blind. We, therefore, concluded that Nelumbo pentapetala 'Yellow Bird' as a ornamental plant should be grown up to 8 in the node number of main rhizome until mid-July.

Demand on specialized feline dentistry has increased over the years, partly due to growing feline population in Korea. Despite the notable increase in the population, not much researches has been conducted on oral disease for stray cats. Thus this research was conducted on 81 adult stray cats from Gwangju in Korea (42 males and 39 females) with average weight of 3.4 kg and also focused on occurrence of periodontal disease (plaque and calculus), feline odontoclastic resorptive lesion (FORL), stomatitis and tooth anomaly. Formation of dental plaque and calculus were abundant on maxilla than mandible, especially distributed much on 4th premolar teeth and 1st molar teeth. After thorough examination of oral cavity, 33 stray cats (40.7%) were found to have oral disease. Eighteen stray cats (22.2%) had tooth fracture which was evident on cuspid and missing teeth were present on 2nd premolar tooth of maxilla and 2nd incisor of mandible amongst 20 stray cats (24.7%). FORL was present on cuspids and 2nd premolar tooth of maxilla among 10 stray cats (12.3%). Stomatitis was involved with FORL, missing tooth, and tooth fracture. Therefore, it was determined that stomatitis, FORL, and periodontal disease were closely associated.

Several epidemiological surveys have reported the prevalence of Toxoplasma gondii infection in stray cats in Korea, but little information is available on T. gondii infection in household cats. The aim of the present study was to assess the prevalence and risk factors of T. gondii infection among household cats reared in Seoul, Korea. A total of 474 blood samples were collected from clinically healthy household cats. All samples were tested using ELISA and PCR. The risk factor analysis was based on a questionnaire filled out by the owners. The overall positive rate for ELISA and PCR assays was 2.2% (10/437) and 2.1% (10/474), respectively. With regard to the origin of cats, the positive rates among cats adopted from the animal shelter and veterinary clinic for stray cats were significantly different (P<0.05). Our study demonstrated that the positive rate of T. gondii infection in household cats was low and that this low prevalence was assumed to be associated with keeping the cats indoors and restriction of eating raw food and uncooked meat. Therefore, we suggest that the owners check the origin of the cats prior to adoption to prevent infection of other animals, including humans.
