The serum ALP3 and TRAP5b levels decreased after weaning; the levels were significantly higher in the pre-than post-weaning period. These results suggest that osteoblastic bone formation and osteoclastic bone resorption slowed after weaning. Breast milk feeding of Asian elephants may play a significant role in osteoblastic and osteoclastic bone metabolism during the growth period.","PeriodicalId":494131,"journal":{"name":"Japanese journal of zoo and wildlife medicine","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135737915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Larger but non-significant differences in egg yolk IgY levels were observed between captive and wild specimens using the current methodology, with smaller non-significant differences detected for egg white IgA and IgM. Thus, the lack of maternal passive immunity in the form of egg antibodies might not be a contributing factor to newly hatched chicks’ resistance to opportunistic pathogens under captive conditions.","PeriodicalId":494131,"journal":{"name":"Japanese journal of zoo and wildlife medicine","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135737922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
