Nutritional parameters in the blood of dams during late gestation and immediately after calving, in the umbilical vein at calving, and in the blood of calves immediately following birth in Holstein heifers pregnant with either Holstein or beef breed fetuses
Get PDFapplication/pdfDairy cattle management lacks consideration of fetal breed, the effect of which on fetal growth and nutrition are unclear. We investigated blood parameters in 12 late- pregnant Holstein heifers with similar (Holstein, n= 5) or different (Japanese Black [n= 4] or F1 cross [n= 3]; Holstein × Japanese Black) fetus breeds and in their um-bilical cords and calves. Samples were obtained from dams 1 week before calving (−1 week) and immediately after calving, from the umbilical vein at calving, and from calves immediately after birth. Dams with beef fetuses had higher serum glucose lev-els (−1 week; p< .05) than those with Holstein fetuses. Plasma total amino acid, total essential amino acid, total nonessential amino acid, and other amino acid concentra-tions were lower in the umbilical veins of dams with calves of the beef breeds than in those of the Holstein breeds (p< .05). Furthermore, serum glucose and plasma amino acid levels were lower in the beef calves than in the Holstein calves (p< .05). Overall, nutrient supply from dams to beef fetuses was lower than that to Holstein fetuses. Our findings may facilitate feeding management of dairy cattle pregnant with beef breeds for ppropriate fetal growth and nutrition.journal articl
ロックダウンと博物館 : 新型コロナウイルス感染症流行下のリトアニア共和国国立博物館のFacebook利用動向の変遷
Get PDFapplication/pdfIn 2020, globally, museums were forced to shut their door to visitors due to preventing the novel virus COVID-19. On the other hand, recently, museums open to society not only on-site but also online. Thus, the virus’s spread would be an occasion to shift museum communications and widen virtual access to the museum. This paper aims to examine whether social media usage changed by long-term closure for nationwide quarantine in 2020. The Republic of Lithuania is the case to examine this research question; 18 national museums that use social media for their public relations are the target of this research. The author recorded 5,586 Facebook posts by Lithuanian national museums from January 1st to December 31st, 2020. The number of posts (before, during, and after the first and second quarantine) is statistically analyzed by the Wilcoxon signed-rank test. Through the year 2020, the weekly average number of the posts repeatedly increased and decreased. The Wilcoxon signed-rank test proved that the weekly average number of the posts increased during the first closure for quarantine than the pre-COVID 19 period ( α =0.05). The weekly amount of social media posts dropped after the first quarantine, and it did not recover by the second quarantine. The usage of social media remarkably increased by the first long-term closure as a reaction to the crisis; but its prominent increase in quantity was not recognized after the first quarantine.journal articl
重度の腹腔内出血を呈した好中球性胆管肝炎の猫の1症例
Get PDFapplication/pdf3歳4カ月齢の雑種猫、去勢雄が食欲不振と活動性低下を主訴に近医を受診した。重度の貧血と腹腔内出血を認め、輸血により改善がみられた。その後精査を希望して、帯広畜産大学動物医療センターを紹介受診した。貧血、肝臓由来酵素の上昇、凝固異常、肝臓の腫大、腹腔内出血等を認め、輸血を実施した。一旦は改善したものの、来院10日後に腹腔内出血により斃死した。病理解剖では血様腹水が重度に貯留し、肝臓表面に多量の血餅付着がみられた。本症例は病理組織学的に好中球性胆管肝炎と診断された。journal articl

キャッシュレス決済発展のための条件 : 十勝のキャッシュレス化を阻害する要因分析
Get PDFapplication/pdfキャッシュレス推進には国力の増強に繋がる様々なメリットがある。しかし日本のキャッシュレス決済比率は2017年時点で21.4％（同年韓国のキャッシュレス決済比率は97.7％）と低い水準にある。そのため近年様々な政策によってキャッシュレス化が推進されている。その一つとして「キャッシュレス・ポイント還元事業」が行われていた。経済産業省のデータによると，この事業の登録加盟店舗数の全道平均は一市町村あたり約490店舗であるが，十勝の平均は一市町村あたり約328店舗と，十勝は道内でもキャッシュレス推進に積極的であるとは言えない。本研究は十勝の消費者を対象に調査し，キャッシュレス決済利用に至るまでの心理的要因を分析することで，地方における普及の課題や望ましい普及のデザインを明らかにし，キャッシュレス発展に寄与する方策を提言することを目的にした。調査の結果，過半数がキャッシュレス決済の将来的な利用に前向きであった。一方で，キャッシュレスの「有用性」や「使いやすさ」自体は理解していても，それらが各サービスの将来的な利用意向に繋がらないことが普及の課題になっていた。決済と連動した家計簿アプリの周知や活用，イレギュラーな決済のアラート通知など受動的な管理のさらなる高度化，利用可能なサービスを一覧できるような仕掛け作りが必要である。Promoting cashless payment has various merits that lead to the strengthening of national power. Nevertheless, Japan's cashless payment ratio was 21.4% as of 2017 (Korea's cashless payment ratio was 97.7% in the same year), which is a low level compared to other countries. In order to overcome this, various policies are currently being implemented to promote cashless payments. As an example, the " Point Reward Project for Consumers using Cashless" has been held until June last year. According to data from the Ministry of Economy, Trade and Industry, the average number of registered stores on the project in Hokkaido was about 490 per municipality, and Tokachi was about 328 per municipality. Therefore, it can be inferred that Tokachi is a region in Hokkaido where the promotion of cashless payments has been delayed. The purpose of this research was to clarify the "problems of popularization of cashless payment services" and "desirable popularization design", and to propose measures that contribute to cashless economic development in rural areas by conducting questionnaire survey to Tokachi’s consumers. As a result, the majority of the respondents were willing to use the cashless payment in the future. On the other hands, even if they understood the usefulness and ease of use of the cashless, these were not led to future usage intentions for each service. It was considered a problem for widespread using services. Therefore, in this research, we proposed "dissemination and utilization of household account book apps linked to payments," "further sophistication of passive management (such as alert notification of irregular payments)," and "listing available services near the place of residence".departmental bulletin pape
乗馬経験者と初心者に騎乗された馬の騎乗時心拍数の比較
Get PDFapplication/pdf乗馬を楽しむ場合、騎乗者は自分の技術レベルに応じた馬に乗ることが、安全のために重要である。そのため、技術レベルを客観的に示すことができる指標があれば、乗馬時の事故減少に役立つ可能性がある。このことから、本研究では騎乗された馬の心拍と騎乗者の技術レベルとの関連を調査し、騎乗者の技術レベルの指標としての馬の心拍の活用を検討した。2016年9月から10月にかけて、芽室町の牧場で実験を行った。北海道和種系馬2頭（6才去勢馬と3才牝馬）を供試した。騎乗者は、乗馬経験が5鞍程度の初心者3名と乗馬経験が2年以上の経験者3名の計6名だった。全ての騎乗者は両方の馬に騎乗した。実験は、騎乗者の乗馬経験に応じて2種類実施した。実験の前後に安静時心拍を5分間計測した。初心者と経験者に騎乗されたとき、心拍数に差がみられた馬がいたことから、適切な馬を選定すれば、馬の心拍数から騎乗者の技術レベルが見分けられる可能性があることが示唆された。また、心拍数より、安静時に対する心拍数変化率のほうが、騎乗者の技術レベルを見分けやすいことが示された。本研究で使用した供試馬より、さらに経験豊富な20才前後の馬や、乗馬施設で利用されることの多い様々な品種で実験を行い、データを収集できれば、より正確に騎乗者の技術レベルを判定する方法が開発できる可能性が示唆された。When enjoying horseback riding, it is important for the rider to ride a horse according to rider’s skill level for safety. Therefore, if there is an index that can objectively show the rider’s technical level, it may be useful for reducing accidents during horseback riding. Therefore, in this study, we investigated the relationship between the heart rate of the horse and the skill level of the rider, and examined whether the heart rate of the horse could be used as an index of the skill level of the rider. From September to October 2016, experiments were conducted at a ranch in Memuro. Mixed breed pony (6 years old gelding) and Hokkaido native horse (3 years old mare) were tested. There were a total of 6 riders, 3 beginner riders who have ridden horse about only 5 times and 3 experienced riders with more than 2 years of riding experience. All riders rode on both horses. Two types of experiments were conducted depending on the riding experience of the rider. The heart rate of resting time as baseline was measured for 5 minutes before the experiment. There was a difference in heart rate between beginner and experienced horses, so if selecting the horse, there will be possibility to show the rider's skill level from the horse's heart rate. It was also found that the rate of change in heart rate during exercise relative to heart rate during resting time is easier to distinguish the skill level of the rider than the heart rate. As a future task, rider’s riding skills would be estimated more accurate if we could collect data by conducting experiments with more experienced horses around the age of 20 and various varieties that are often used in equestrian facilities, rather than the test horses used in this study.departmental bulletin pape
