There is not much information about the frequency and causal factors of haemolactia (i.e., the presence of blood in milk). In this study, haemolactia in dairy cows was investigated by using a device for quantitative determination of blood in milk, which is being developed by the Tokachi Foundation. Milk samples (colostrum) from 4 cows and pinkish milk samples from 2 cows with mastitis or an external wound to the udder were obtained at two dairy farms in eastern Hokkaido between July and November 2019. The average concentrations of blood in the colostrum on the 3rd day after calving was 0.0028±0.0027%,which is less than the 0.01% detection limit of visual inspection. The concentration of blood in the milk from the cow with mastitis ranged from 0.25% to 0.0012% over the 4 days, which gave the milk a pinkish tinge. The concentration of blood in the milk from the cow with an external wound to the udder ranged from 0.24% to 0.011% over 4 days; this milk was not noticeably pink on the 4th day by visual inspection.","subitem_description_type":"Abstract"},{"subitem_description":"酪農現場では、乳房内出血による血乳が搾乳されることがある。一般的に血乳は前搾り時に発⾒できるため、生乳出荷事故につながることは少ないが、その場で廃棄されるため、原因や血液混⼊割合などの詳細が明らかではない。本研究では、とかち財団が開発している簡易型血乳検査装置を用いて、現場での現況調査を実施した。調査対象は釧路地方の２酪農場において、2019年6月に分娩した４個体から搾乳した「①初乳」ならびに、同年10～11 月に、前搾り時に血乳と判断された個体乳（「②乳房炎」、「③乳房の打撲」が原因と推定される血乳が突発的に生じたそれぞれ１個体）とした。これらの血液濃度を同装置で推定した上で、体細胞数をブリード法により測定した。分娩後３日目における「①初乳」中の推定血液濃度は0.0028±0.0027％で、目視（色沢）で確認できる限界濃度（約0.01％）より低かった。「②乳房炎」が原因と推定される血乳の推定血液濃度は0.25～0.012％で、明らかなピンク色を呈し、出血前の体細胞数は2,660[千個/ml]と高い値であった。「③乳房の打撲」が原因と推定される血乳の体細胞数は51±39[千個/ml]と比較的低いことから、炎症性の可能性は低いと推察された。その後４日間の推定血液濃度は0.24～0.011％で、日にちの経過とともに低下した。","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"","nameIdentifierScheme":"ISNI","nameIdentifierURI":"http://www.isni.org/isni/"}]}],"familyNames":[{"familyName":"猫本","familyNameLang":""}],"givenNames":[{"givenName":"健司","givenNameLang":""}],"nameIdentifiers":[{"nameIdentifier":"1716","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9331","nameIdentifierScheme":"教員総覧","nameIdentifierURI":"https://www.rakuno.ac.jp/archives/teacher/9331.html"}],"names":[{"name":"猫本,
