Abstract:
The objective of the present study was to investigate the effect
of pre-milking mechanical teat stimulation on milk yield and
milking performance of dairy buffaloes in early lactation. For this
purpose, twenty-two healthy Italian Mediterranean buffaloes in
their first to third lactation and in early lactation (<120 days in
milk) were subjected to two treatments of teat stimulation: i)
washing of the teats with water for about 5 s and attaching of the
milking unit within 60 s, without any pre-milking massage (farm
milking routine); ii) fast pulsation (FP), achieved by increasing
pulsation rate to 120 pulsations per min during the first 60 s after
application of teat cups. Each treatment lasted for 10 days and the
following parameters were measured: milk yield (kg/milking),
milk yield at 2 min after unit attachment (kg), time between milking
unit attachment and its automatic removal (min), peak milk
flow rate (kg/min), and milking time to reach peak flow rate (min).
The average milk flow rate (kg/min) was calculated by dividing
milk yield by the actual milking time. Milk yield was not affected
by mechanical pre-stimulation and during the first 2 min of milking
20.2% and 19.6% of total milk yield were milked respectively
when treatments 1 and 2 were applied. The time elapsed from
attachment of the milking cluster until its automatic removal was
less than 8 min both for buffaloes subjected to FP, and for buffaloes
subjected just to washing of the teats before attaching the
milking unit. FP stimulation did not show an enhancing effect on peak and average milk flow rates and on milking time to reach peak flow rate.
