| dc.description.abstract | The variables affecting the milk productivity have been discussedin various articles through different methods. A recent studyusing path analysis shows that three variables significantly affectthe 305-day milk yield of Holstein Friesian cows. These variablesare parity, first calving year and lactation length. Calving seasonis another variable which appears to be significant in a differentstudy. The aim of this study is to provide a simultaneousmultilateral analysis among the milk yield, these three variablesand a new variable calving season. The analysis was realizedthrough a Bayesian network built over the findings of the pathanalysis. 17,109 records of Holstein Friesian cows calvedbetween 2001-2011 years were analyzed. The estimatedBayesian network showed that younger cows produced moremilk. Lactation length and parity do not depend on each other.Cows reached their highest amount of milk yield on their 4thparities. Milk yield is mostly affected by lactation length. Finally,first calving year, parity, lactation length and calving seasonshould be considered as criteria in a selection study to increasethe milk yield. | en_US |
