A technique for constructing lactation curves using logical assumption and Verhulst’s logistic function for predicting the cows’ milk production is described. A new modeling lactation method that is based on solving the equation that describes the rate of change of milk production, depending on time elapsed since calving is presented. The statistical parameters of the adequacy of the models recommended in the literature for describing the lactation curve of cows and our proposed models were calculated Approximation accuracy allows for the identification of models that most reliably describe the lactation curve in the example of cattle.","PeriodicalId":103087,"journal":{"name":"Live and Bioabiotic Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122556390","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}
