Boost for NZ, Nordic Jerseys genetic link
A new collaboration is underway to improve the genetic links between the New Zealand and Nordic Jersey cattle populations.
The equivalent of ‘currency’ for cows will be updated next month to better reflect the industry’s focus on efficient, high quality milk production, says LIC.
Production worth (PW) is an economic index calculated for all New Zealand dairy cows as an estimate of their lifetime production ability. It helps farmers identify the top performers in their herd, to decide which cows to keep or cull, and to help figure a value for buying or selling.
Four traits figure in the PW calculation: milk volume, milk fat, protein and liveweight. A fifth trait will be added in February -- somatic cell.
Somatic cells are produced by a cow’s immune system to fight an inflammation in the mammary gland (mastitis). Some cows are more prone to it than others and it can curb their ability to produce milk, even when the infection is cured.
The update will make PW more relevant for today’s farmers, says Malcolm Ellis, dairy farmer and LIC’s general manager NZ markets.
“Somatic cell can hit a cow’s health, production and reproduction. On our farm PW is a tool to lead culling decisions, to identify and retain the most valuable cows in the herd; but like many other farms we also review somatic cell data to help inform those decisions.
“We want to make that secondary consideration seamless, with all that information in PW.”
It will be the first update of PW since it was introduced in 1996 by the forerunner to LIC. Somatic cell was added into BW in 2005.
Fonterra shareholders are concerned with a further decline in the co-op’s share of milk collected in New Zealand.
A governance group has been formed, following extensive sector consultation, to implement the recommendations from the Industry Working Group's (IWG) final report and is said to be forming a 'road map' for improving New Zealand's animal genetic gain system.
Free workshops focused on managing risk in sharefarming got underway last week.
Annual farmer gathering, the South Island Dairy Event (SIDE), is set to make history as it heads to Timaru for the first time.
Installing 400 solar panels at their Taranaki piggery and cropping operation will have significant environmental, financial and animal welfare benefits for the Stanley family.
WoolWorks, New Zealand’s largest wool-scouring company, has partnered with the Lions Club of Riverton to help raise money for much-needed repairs to the Southland town’s swimming pool.
OPINION: Fonterra may have sold its dairy farms in China but the appetite for collaboration with the country remains strong.
OPINION: The Listener's latest piece on winter grazing among Southland dairy farmers leaves much to be desired.
