New UHT plant construction starts
Construction is underway at Fonterra’s new UHT cream plant at Edendale, Southland following a groundbreaking ceremony recently.
But the pendulum could be about to swing back.
Until the late 1960s, the Jersey breed accounted for 70% of the national herd, today it's at 12.1% and that, according to LIC jersey bull acquisition manager Malcolm Ellis, "is a dilemma - not just for the breed but for the whole industry.
"The industry is better with Jerseys, it is one hell of a breed that's worth fighting for and there's a lot to be excited about now and in the future with the work we're doing.
"Based on the amount of milk solids they can produce for each kg of liveweight, Jerseys have a tremendous reputation for being a highly efficient breed, and I've seen farmers make this breed work across all systems.
"A system 5 Jersey farm I visited recently, for example, has a top cow just short of 500kgs liveweight - and it's going to hit a tonne of milk solids this season. Their 2-year-olds consistently exceed 600kgs milk solids in their first lactation which is 1.18 times their liveweight.
"That's massive, and it doesn't stop there - in system 3 and 4 farms I've seen 400kg Jerseys nailing up to 460kgs milk solids each, while system 1 and 2 rockets are also cracking the magical 1kg of milk solids for every 1kg of liveweight.
"These farmers are making the breed work for them, but the biggest problem facing Jerseys right now is they're currently running fourth in a three-horse race when it comes to farmer's mating choices, and their gene pool is getting lower each season."
New Zealand dairy farmers understand Breeding Worth (BW) as a basis for bull selection and a goal for their herd but Malcom says declining numbers mean the Jersey teams just haven't been up there in recent years so some have understandably made the switch to the popular Kiwicross.
"The Jerseys have got to regain BW respect because I know in this game, if you don't rock on the wall chart then you don't perform because that is what farmers base their decisions on.
"They're in a race against time to recapture genetic gain, but we've got to balance that with diversity in the genes too."
The Kiwicross™ cow is the most popular in New Zealand, but Malcolm says its continuity is enhanced with strong parent breeds, Jersey and Holstein Friesian, which allows the blend of traits that farmers want.
