Milking on the run
The national milking speed project,
initiated in 1980 to provide sire proofs for
milking speed, will continue during the
summer of 1982 as a joint effort between
Canadian A.I. Units and the Holstein -
Friesian Association of Canada. To date
258 A.I. sires have received evaluations
for milking speed.
The time which it takes for a cow to milk
out is a significant economic concern as
milking speed is inherited to the same
degree as milk yield and conformation.
Therefore. through selection, a breeder
may improve the speed at which his cows
milk.
Milking speed proofs are computed
based on objective measurements facili-
tated by stopwatch timing. Sire proofs for
milking speed are then adjusted for
differences between cows with respect to
age. stage of lactation and total yield.
Bulls are required to have a repeatability
of 55 per cent or higher. based on 30
daughters in five or more herds, to receive
an evaluation for milking speed. All proofs
are expressed in terms ul ratings: Very
Fast, Fast Average, Slow and Very Slow.
In addition to the stopwatch measure-
ment. herd owners will be asked for their
estimate of thc speed at which their cows
milk. This subjective estimate will he
recorded prior to the milking of the herd.
At the completion of thc project the
relationship between subjective and ob-
jective measurements will be analyzed. If
the estimates arc similar then the need for
an actual stopwatch measurement could
be eliminated.
For the purpose of research, hcrd
owners will also be asked for an estimate
of their cow's temperament at the time of
milking. Temperament information will
be solicited with the aim of evaluating
sires for this trait.
Based on the past success of the milking
speed project, the 1982 program will
provide the dairyman with further infor-
mation enabling him to develop a more
profitable herd with uniform milking
speed.
