Results just published in the NMR Annual Production Report for
the year ending September 2005 show that average milk yield for
all NMR-recorded cows is, for the first time, more than 8,000kg.
With 92.5% of recorded lactations, the Holstein breed has an annual
average of 8,212kg - up 106kg from the previous year.
While all breeds accounting for 1% or more of lactations increased
average milk yield, the Guernsey breed showed the biggest increase
in 2004/05 compared with the previous year, adding 133kg to its
average to stand now at 5,554kg. This is a 2.5% increase in average
yield for Guernseys compared with a 1.3% increase for the Holstein
The average yield of NMR recorded herds, which accounts for 60%
of all dairy cows in Britain, has increased by 14.5% in the past
five years. Leading the increase is the Holstein breed where average
milk yield has increased by 15.4%.
Average fat percent has also increased in all the main breeds
and although the British Friesian only represents 0.8% of total
lactations, the breed shows the largest increase in fat to 4.06%
- a rise of 0.9% - putting them well ahead of the Holstein average
that is now 3.85%. Protein levels have dropped or remained static
across the board.
Somatic cell counts have continued their upward trend during the
year - the only main breed to have deviated from this is the Jersey
where cell counts have fallen slightly. Average cell count for
all NMR herds is 193,000/ml, with the Holstein averaging 194,00
cells/ml - up from 187,000 in 2003/04. The average cell count for
the Guernsey is 200,000/ml. Of the pure dairy breeds, the Shorthorn
and Montbeliarde have the lowest average cell count at 167,000
and 168,000 respectively.
