Domestic cats (Felissilvestriscatus ) are known to have lesser and hypertonic urine excretion(urine volume: 22–30 mL/kg per day; specific gravity: 1.015–1.050) than those of domestic dogs( Canislupus familiaris); urine volume: 24–40 mL/kg perday; specific gravity: 1.015–1.040). These have been implicated as factors for feline incidence of struviteurolithiasis and felinelower urinary tract disease, which are diseases that affect the bladder or urethra. We conducted comparative studies on therelationship between fluid intake and urine volume/urine specific gravity under 2 conditions—diet (condition A) comprising"dry food"( 5.6% moisture) and ad libitum drinking water and diet( condition B) comprising" wet food"( 74.8% moisture) andad libitum drinking water—in acclimated cats( n=7) kept separately in cat cages in an animal rearing room at 25°C. The perdiem water intake (apparent water intake) in condition A was on an average 66.9 ± 22.1(mL), while the totalfluid intake (absolute water intake), which is the sum of the amounts of water in the food and the water intake, was on anaverage68.2 ± 23.3(mL).Further, the average water intake under condition B was only 22.7 ± 20.13( mL), but the absolutewater intake was on average 95.6 ± 37.6( mL), meaning that wet food resulted in a higher absolute water intake amountthan dry food. Regarding the urine volume and the urine specific gravity, urine volume and urine specific gravity with the dry food diet(condition A) were 28.8 ± 11.8 (mL) and 1.049 ± 0.01, respectively, but the mean urine volume and urine specific gravityunder condition B were 49.5 ± 31.4(mL) and 1.030 ± 0.01, respectively, showing that compared to the dry food group, thewet food group had a significantly higher urine volume and lower urine specific gravity. The present study proves that in an average rearing environment, the urine volume does not increase and urine specificgravity is hypertonic when the cats are provided dry food diet, despite increase in the apparent water intake. Further, theurine volume increases and urine specific gravity decreases when the cats are provided wet food diet( canned or pouched),although the apparent water intake is low. The present study shows that differences in the diet are factors for the increasedincidence of struviteurolithiasis and FLUTD in cats

サラブレッド デ マナンダ ハンショクガク

University of Tokyo opened its own farm one year before I finished my three-year research in the field of livestock surgery. And I was assigned, as the status of a research student, to look after the livestock in the new farm. As a veterinarian, I was also expected to extend support for reproduction of foreign-based brown haired wagyu via artificial insemination. The farm\u27s budget was fixed as 70% of the income earned in the previous year. Obviously there was no budget to purchase thoroughbred at this farm. So I proposed a barter deal of giving Arab horse belonging to our farm and receiving a 23-year-old thoroughbred that had a record of two miscarriages in the Goryo Farm. Despite great concerns, the thoroughbred gave birth to a filly in March 2nd, 1964. The same year, we received another imported mare that had jaundice, and got a foal. Subsequently, we got a mare which was not pregnant for nine years from a private farm. Sure enough that was another successful case of giving birth to a foal. Some of these foals ended up participating in thoroughbred stakes like Oka-Sho, Satsuki-Sho and Derby races. Positive administration of hormones was the key to the success. However, none of those hormones are sold today due to various potential dangers. The field of reproduction learned through such experience still remains as part of my treasure

ニホンザルの内部寄生虫は、宿主であるニホンザル自体の疾病や死亡原因となるだけでなく、ヒト社会と生息域が重なることにより、公衆衛生上の問題として人獣共通感染症(zoonosis)の病原体ともなりうる。私たちは異なる生息地にすむ二つの野生ニホンザル群から糞を採取、分析、内部寄生虫保有率を比較した。調査対象は、人里に近い帝京科学大学に近接する山梨県大月市の野生ニホンザル群と、無人の宮城県金華山島の野生ニホンザル群である。大月群での内部寄生虫保有率は75%、金華山群では18,8%であり、主たる寄生虫は鞭虫(Trichuris sp.)であった。結果は、二つの群れの自然人為環境の違いが内部寄生虫保有率の違いに影響を与えていることを示唆する。Endoparasites in Japanese Macaques not only bring harm to their host, but also possibly become the pathogen of zoonosis, because the habitat areas of Japanese Macaques are often close to humans. We collected and examined the fecal sample of wild Japanese Macaques of two troops living in the different habitats, and compared the possession rate of endoparasites. One of the target troops was Kinkazan troop, ranging in the uninhabited Kinkazan island in Miyagi Prefecture, and another was Otsuki troop, ranging near to human habitat in Otsuki City, Yamanashi Prefecture, that is close to Teikyo University Science and Technology. Based on these samples, we performed the fetal examination of endoparasites. The possession rate of endoparasites was 75% in Otuki troop, and 18,8% in Kinkazan troop, and the main endoparasites was Trichuris sp.. The results suggest that the difference of the habitats of both troops influenced on the difference of the possession rate of endoparasites

The objective of this study was to verify the effect of professional interventions by physical therapists on dachshunds that had intervertebral disc herniation with persistent inability to walk. Subjects were 5 dachshunds diagnosed with intervertebral disc herniation and associated paraplegia; they had failed to regain their ability to walk even 2 months after corrective surgery. We administered professional physical therapy and low-frequency therapy to the subjects for 2 months. At the end of 2 months, 3 dogs were able to stand up and maintain the standing position, while 2 were capable of assisted walking. We presumed that this improvement in the locomotory function of the dogs was considerably influenced by the induction of spinal reflexes and exercise therapy that were based on motion dynamics. Because the therapy was based on the knowledge of physical therapy for humans, the results suggest that physical therapists can contribute to the enhancement of animal medical care and, thereby, the welfare of owners

Budgerigars use contact calls and warble-songs. Previous studies have found that they acquire these songs through vocallearning, but to date, there have been no long term experimental studies of their vocalizations or social interactions. Thepurpose of this study was to establish a basic understanding of budgerigar vocal ethnology. We recorded all sounds made byfour budgerigars (male=4, female=3) kept in separate cages in a same experimental box for fixed periods (12-h light/darkcycle). There was great diurnal variation in vocalizations, but the variation decreased from lights up to off and during thelights-off period. The variation in vocalizations was also positively related to changes in humidity. The frequency of soundsproduced by the group of males was higher than that of the group of males and females mixed together. The response rate forcontact call varied among individuals which suggests that hierarchy existed in vocal communication. However, the hierarchychanged depending on the membership in a group

In recent years, ongoing daily dental cleaning to domestic dogs has been clinically evaluated by veterinary clinicians to be effective in the prevention of periodontal diseases including zoonoses, especially in the aging dogs. In this study, in order to improve the canine oral hygiene, we have compared the various dental cleaning methods based on the number of bacteria on the teeth using dental care products for dogs which are commercially available. In addition, we have isolated zoonotic bacteria of Capnocytophaga spp and then examined changes in the number of the bacteria after the dental cleaning. Of the seven methods of dental cleaning (direct methods; n=4, indirect methods; n=3), all the direct dental cleaning methods achieved a high rate of bacterial reduction and appeared to be effective in the prevention of periodontal diseases in dogs. The present findings indicate that ongoing canine dental cleaning significantly reduces intraoral bacteria as well as dental plaques, thus reducing the risk of periodontal diseases

Body condition score (BCS) is assigned on the 5-point scale which is based on visual inspectiion of dogs. This is one of the most common methods in veterinary clinical. Body fat percentage is obtained by bioelectric device (BID) to evaluate bioelectric impedance of body composition. To estimate the relationship between the body condition score and the body fat percentage, physical examination records for nineteen healthy family dogs kept by TUS students were conducted. . With simple regression analysis a significant relationship was found between BCS and body fat percentage (r=0.489,P<0.05). Both noninvasive methods of using the BCS and body fat percentage as measured by the BID were effective to determine obesity of dogs in the veterinary hospital. These procedures proved to be useful as clinical techniques that should be utilized by veterinary nurses

Professor Takeshi Kobayashi was a leading and representative figure in interpretation of Japan. He passed awaysuddenly on March 13th in 2013 at the age of 55. This paper describes a brief history of interpretation in Japan, following thesteps that Professor Kobayashi had taken in the field of interpretation and environmental education. Professor Kobayashistarted his interpretation career at the Takao Visitor Center as a ranger of the Nature Conservation Society of Japan in 1983.He established the Center for Environmental Studies in order to focus on nature interpretation in 1988. He had also coordinatedthe Japan-U.S. Interpreter Training Seminar, which was jointly supported by the U.S. National Park Services, since 1995 anddeveloped a number of other interpreter training programs in Japan. He played a central role in those training courses in 1990s and 2000s of Japan, during which the Ministry of the Environment and the Ministry of Education, Culture, Sports,Science and Technology were active in offering training for interpreters and outdoor educators. He became a professor at theGifu Academy of Forest Science and Culture in 2005 and a professor at the Department of Animal Sciences, the Faculty ofLife and Environmental Sciences, Teikyo University of Science in 2010. He developed courses for instructors and trainers ofenvironmental education and interpretation. Professor Kobayashi helped offering opportunities for domestic and internationalinterpreters to meet and to develop network. He had been engaged in developing interpretation through projects and events,human resource development, and networking, and greatly contributed to the enhancement of interpretation in Japan till thelast day
