Despite a severe drought that resulted in a shorter milking season for many of New Zealand’s dairy farmers, milk production only decreased by 1.6% during the 2012/2013 season.
According to statistics released by LIC and DairyNZ today, New Zealand’s dairy cows produced 1,658 million kilograms of milksolids in 2012/2013, which is down from the record level of production achieved in 2011/2012 but still above 2010/2011 figures.
Both organisations agree the achievement is a testament to the resilience of farmers and their ability to manage through a drought with minimal impact to their business and the New Zealand economy.
The strong performance was also helped by an increase in cow numbers, good milk production before Christmas and a strong dairy season in Canterbury, Otago and Southland.
The annual New Zealand Dairy Statistics document provides a comprehensive review of the dairy industry with statistics from the LIC database, Animal Evaluation database, dairy companies, Animal Health Board Annual Report, NZ Real Estate Institute and Statistics New Zealand.
The statistics represent all New Zealand dairy farmers, and include cow production and population, operating structures, breed breakdown, herd testing, artificial breeding, calving, milk prices, land prices and disease control.
Herd reproductive performance has also been added this year, with figures sourced from herds with adequate pregnancy diagnosis information recorded in LIC’s MINDA herd management software, which formulates a Fertility Focus Report and 6 week in-calf rate for the herd.
The new section has been added in response to an increasing number of farmers pregnancy testing their herd and utilising DairyNZ’s Fertility Focus Reports which allows them to measure and manage their herd’s performance.
Since DairyNZ’s InCalf programme was launched in 2008, use of these reports increased to 2,331 herds in 2012/2013, and their average six week in-calf rate for the season was 66.5%.
Herd production is fundamental to farm profitability and the industry target, from the DairyNZ InCalf programme, is to get 78% of the herd in-calf within in the first six weeks of mating.
