We also investigated the relationship between the age of mares and their AMH levels. The possible effect of seasonality of AMH levels was also assessed. Twenty-three mares between 6 and 24 years of age were included in the experiment. Mares were divided into two groups: Group 1 included mares aged 6 - 15 years (n = 11), while Group 2 included individuals older than 15 years of age (n = 12). Venous blood was collected and ovarian activity was monitored parallelly by transrectal ultrasonography. Serum AMH concentrations varied widely between the two different groups. AMH concentrations were significantly lower in old mares than in younger animals. A positive relationship was detected between AMH concentration and the number of medium-sized follicles (P = 0.022), large follicles (P = 0.016) and the total follicle count (P = 0.026). No seasonal effect was detected.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the study revealed that female red pandas are polyoestrous, with a second oestrogen peak after mating. Progesterone changed in a cascading fashion, peaking and then gradually declining. Successfully mated females showed higher levels of progesterone than unsuccessfully mated females, which had no peak in progesterone after mating. Ceruloplasmin was measured to confirm pregnancy, but its value as a pregnancy diagnostic factor was not confirmed. These results provide significant insights into the reproductive physiology of red pandas and lay the foundation for additional research towards improving the management and breeding strategies for this threatened species.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":"204-209"},"PeriodicalIF":0.7,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142764745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Replicating the natural diet in captivity is commonly accepted and recommended. Given the diverse nutritional composition of prey, supplementation may become necessary. The captive environment poses unique challenges, making sharks susceptible to an array of health issues, including numerous diseases. Mitigating these risks demands detailed husbandry practices, an appropriate physical environment and a balanced diet. Supplementation, encompassing vitamins and minerals, becomes imperative for the provision of essential nutrients. This complexity has rendered the formulation of an adapted feeding plan for aquarists exceptionally challenging. The scarcity of information in these species adds to the issue, mandating extrapolation from various shark groups and to species with analogous characteristics. This literature review concentrates predominantly on benthic and pelagic shark species prevalent in contemporary aquariums. The central argument posits that dietary choices in captivity rely on factors such as availability, quality and consistency of supply. The advocated approach highlights the importance of a balanced, diverse feeding that closely mirrors natural diets. It is then crucial to emphasize that these are general guidelines, and the specific dietary requisites may diverge between shark species. Collaborating with experts in marine biology, shark husbandry and veterinary care is imperative for the formulation and perpetuation of an adapted diet for captive sharks.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":"235-261"},"PeriodicalIF":0.7,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report presents a case study in which M. hyopharyngis (along with other bacteria) was isolated from the joint of a pig showing lameness.Case presentation: A Hungarian farm was repopulated with 250 gilts and 1,700 finishers after undergoing a complete depopulation and disinfection. Two days later, cases of diarrhoea and septicaemia caused by Salmonella enterica serovar typhimurium were seen in the finishers. At the same time, following the first farrowing, swollen joints were observed in 21-25 days old piglets.

Analysis of the joint samples revealed the presence of Staphylococcus haemolyticus, Staphylococcus hyicus, Aerococcus viridans, Trueperella pyogenes, Streptococcus agalactiae and M. hyopharyngis.Conclusions: This is the second isolation of M. hyopharyngis from joints, which highlights the necessity of a better understanding the biology of this often-overlooked species, and its role in the progress of arthritis or other lesions.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":"155-160"},"PeriodicalIF":0.7,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142103236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
