Abstract
Costs related to the control of lactating cows and milk sampling are quite high, but
obtained data and their accuracy are not satisfactory. Consequently, results of
selection assessment of bulls’ fathers and mothers are not complete (Sprengel et al.,
2001). Costs of milk productivity control are mostly covered by producers
themselves, which directly affects their financial profit. As a solution for such
situation, Bavarian authorities in cooperation with scientific institutes started using
a new measuring device called Lacto-Corder (Dodenhoff et al., 1999; Dodenhoff et
al., 2000). This device is more efficient in assessing cows’ productivity, lactating
ability and udder health, and is also used for milk sampling (Worstorff, 1993).
Lacto-Corder as a measurement device is recognized by the International
Committee for Animal Recording (ICAR). The device is composed of two parts,
one being hydraulic and the other electronic. Hydraulic part regulates milk flow
through the measuring area, which further consists of 60 separate electrodes that
measure milk flow each 0.7 seconds. Electronic part refers to operational area for
data collection and storage (including keyboard and display). Advantage of milking
with Lacto-Corder is a direct isolation of milk sample into coded bottle, which is
further analyzed. It is relatively light (app. 2.3 kg) and small in size and adjusted
to conditions of milking site, thus making measurement procedures easier. It is
equipped with rechargeable battery lasting for 16 hours. Additional equipment of
Lacto-Corder is: printer, diskettes, diskette reader and laptop. The aim of this paper
is to introduce scientific and professional audience with advantages of Lacto-
Corder and its potential users.
