The production performance of multiparous lactating Sahiwal cows (n = 24) was evaluated according to bothmilking frequency and method. Selected animals were randomly divided into four groups containing six animalseach under a completely randomized design. Cows in groups A & B were milked by the hand milking methodthree times per day, respectively. Similarly, cows in groups C & D were milked by the machine milking method twoand three times per day, respectively. All animals were maintained under uniform feeding and managementconditions. Dry matter intake was high in animal groups milked three times per day, and it remained unchangedbetween the hand and machine milking methods. Milk yield was higher (P < 0.05) in cows milked three timescompared to those milked twice per day, and it did not differ between hand and machine milking methods. Milkfat percentage was higher (P < 0.05) in cows milked twice per day compared to those milked three times usingboth machine and hand milking methods. The percentage of total solids showed a similar pattern as the fatpercentage. However, percentages of protein, lactose, and non-fat solids in milk were not significantly different(P > 0.05) among the treatment groups. Collectively, the results show that milking three times per day instead oftwice at 8-hour intervals can enhance milk yield in Sahiwal cows using both hand and machine milking methods.
