Home' NZ Dairy Farmer : March 2016 Contents E uent machines are expensive
e conventional way of managing e uent solids is to use machines:
machines that separate the solids; machines that break up the solids;
machines that stir the solids.
But as every farmer knows, such equipment is very expensive. ere s
the initial cost of buying the gear. en there s the ongoing cost of
running it. And, of course, there are the inevitable costs of maintaining
the machinery. It all adds up.
Ambulance at the bottom of the cli ?
The fundamental drawback of these effluent machines is the reactive
nature of them. They mostly come into play after the problem has set in --
when solids have formed or the crust has developed. As as a cure to these
problems, the machines are adequate.
But what if you could stop the problem from happening in the rst
place? As the saying goes, prevention is better than cure.
Can you prevent solids from occurring?
In the UK, scientists have discovered that crust and sludge are merely
the symptoms of the real problem and that the cause of pond solids
is microscopic creatures living below the surface ese anaerobic
bacteria separate the e uent bres and send them to the surface to
form the crust and to the bottom to form the sludge.
Scientists then realised that the way to beat these bacteria was relatively
simple: put counteractive bugs into the e uent pond. ese corrective
micro-organisms are called Aerobic Bacteria -- SLURRY BUGS.
How do Slurry Bugs work?
Slurry Bugs digest e uent bre. It's their food. And if su cient
numbers of Slurry Bugs are in a pond eating the e uent bre, the raw
materials needed by the bad bugs to make the crust are removed. at
means no solids can develop.
More than that, Slurry Bugs convert unstable Nitrogen into a form that
plants can uptake. at turns your e uent into a better lique ed fertiliser.

No prize money and a low
milk payout did little to
dampen the enthusiasm of
entrants to the largest dairy show
in New Zealand.
A record number of entries
were received for the NZ Dairy
Event held over three days at
Manfeild in Feilding recently. The
event showcases the finest in
dairy genetics with the best cattle
from all around the country.
Event manager Neville
Turnbull said 200 head of calves

Invercargill and Dargaville

Because of the downturn in
the industry, we halved the entry
fee and there were no cash prizes,
only a few sponsors prizes and we
still had record entries. It goes to
show the commitment these
breeders have to the event.
The downturn hit trade
exhibitors however as the number
of these dropped from 28 to just
Tradespeople are experiencing
tight finances, he said.
We usually have regulars who
support us year in year out but
unfortunately, a number of them
pulled out. Hopefully, things will
look better for them next year.
Entries to the auction were also
down with only 18 lots going

I think this may have been due
to having no reserves, he said.
Farmers were worried they
would not get good value from the
sale so were a bit hesitant. There
was no guarantee of what price
they were going to get.
The top price fetched was for an
ayrshire calf which sold for $7000.
Turnbull said the event now in
its eight year, is a prestigious

These youth are the future of
event and industry. We work hard
to make sure their section runs
well and they get good value
while having fun.
Turnbull said putting on the
event cost $100,000 but worth
thousands of dollars to the region.
