Numerous structural changes of the fox ligaments during cage housing is re-flected, which decrease in the thickness of bundles of collagen fibers and their compositional density compared to the standard structure (in wild individuals). Morphological transformations that can significantly reduce the strength and elasticity resistance of the ligaments and the biomechanical potential of the joint are shown. 23 fox individuals, including 15 individuals of the cage housing and 8 representatives of the natural habitat were studied. The re-search used a comprehensive methodological approach, including anatomical preparation, light microscopy of histological sections, scanning electron microscopy, micromorphometry and statistical analysis of the obtained digi-tal data. According to the results of the study, it was found that fox individuals from natural biocenosis, have colla-gen structures of the lateral ligaments different in waving and packing density from ones of cage housing, which can contribute to ensuring their biomechanical domination.","PeriodicalId":393002,"journal":{"name":"Bulletin Samara State Agricultural Academy","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128364522","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}

During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.","PeriodicalId":393002,"journal":{"name":"Bulletin Samara State Agricultural Academy","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125392443","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}
