Estimation Of The Factors Affecting Lactation Milk Yield Of Holstein Cattle By The Adaptiveneuro-Fuzzy Inference System, Aycan Mutlu Yağanoğlu
Turkish Journal of Veterinary & Animal Sciences
The aim of this study is to estimate lactation milk yield of Holstein cattle using first calving age, lactation period, and service period with (ANFIS) adaptive neuro-fuzzy inference system. The input variables for the system in the study were first calving age, lactation period, and service period. The output variable from the system was lactation milk yield. Predicted values obtained from the ANFIS were compared with the observed values. Twenty-seven rule functions are used to obtain the best model and 1000 epochs are used to estimate the accuracy of the training and testing error. The relations between the output and …

The aim of this study was to determine the effects of κ-casein, β-lactoglobulin, prolactin, and DGAT1 (diacylglycerol acyltransferase1) gene polymorphisms on milk yields in Holstein cows raised in Antalya province, Turkey. A total of 517 cows were genotyped by the PCR-RFLP method to detect κ-casein/HinfI, β-lactoglobulin/HaeIII, prolactin/RsaI, and DGAT1/Cfr1 polymorphisms. In the study, two types of alleles were identified as A and B for κ-casein, ß-lactoglobulin, and prolactin loci, while K and A alleles were detected for DGAT1 locus. The frequencies of A and B allele were calculated as 0.8279 and 0.1721 for κ-casein, 0.4662 and 0.5338 for ß-lactoglobulin, 0.8762 …
