  6. 5. On Predicting Milk Yield and Detection of Ill Cows

    University essay from KTH/Reglerteknik

    Author : Nancy Grennstam; [2005]
    Keywords : ;

    Abstract : The fully automated milking system VMS has different functions which complements the actual milking of cows. This master thesis presents a method to improve the calculation of milk yield in dairy cows for the VMS. This report also investigates if it is possible to improve the algorithm for finding cows with mastitis (udder inflammation). READ MORE
