Selected muscles sampled (1 cm2) from the forelimbs of both cattle and camel were taken from the middle part of the muscle bellies (from the biceps brachii, triceps brachii and deltoideus), fixed inBouin’s solution and prepared forhistochemical analyses. \u0000The photomicrographs obtained from the biceps brachii, deltoideus and triceps brachii among both cattle and camel demonstrated the morphology of the different fibre types (type I, type IIA and type IIB). Muscle fibre types showed different proportions. Even though the overall mean proportion of muscle fibre type I, type IIA and type IIB could not present any significant (p>0.05) differences between the camel and the cattle looking at it holistically. As revealed in this work, the effects of the interactions of species versus age, species versus muscle and muscle versus age on the proportion of muscle fibre type I revealed that the deltoideus muscle of 1 year old camel had significantly (p<0.05) higher proportion. Type IIA muscle fibre obtained from the deltoideus muscle of 5-year-old camel showed a significantly highest value, while muscle fibre type IIB showed significantly higher value from the triceps brachii of cattle aged 1 year. The importance of the knowledge of microscopic characteristics in the determination of myofibre types could be of help in advancing the knowledge on muscle morphology (anatomy) and as well be of help in meat science industry.","PeriodicalId":437076,"journal":{"name":"Journal of Veterinary Anatomy","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123604693","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}

Thus, sheltered environments present unique opportunities to study wild mammal aging and compare aging-related disorders to those of similar domestic animals. We evaluated two aged red fox vixens that had lived in a park setting where they were not caged, and were provided an environment that reflected a natural setting as closely as possible, while providing for proper nutrition and health care. During their 14th year, both foxes developed symptoms suggesting orthopedic and renal deterioration. After diagnosis, monitoring, and humane euthanasia, postmortem evaluation revealed degenerative joint and renal disease, each closely resembling organ-specific pathology of aged domestic dogs. Based on evaluation of these foxes and other recent reports, we hypothesize that underlying mechanisms for late life pathological changes reflect broadly and deeply conserved response capacities and not artificial environments, provided that shelter, nutrition, and health care are adequate to minimize stochastic mortality that prevails in the wild.","PeriodicalId":437076,"journal":{"name":"Journal of Veterinary Anatomy","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114159599","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}
