AFTER purchasing livestock, the single great-
est direct cost you’ll incur is feeding them, so
it stands to reason that an efficient feeding
system is paramount to your bottom line.
Aerobic spoilage is responsible for making silage
unpalatable, but it is also a primary cause of meta-
bolic disorders in ruminants due to increased myco-
toxins and pathogenic species, reduced dry matter
intake, feed conversion ratio and subsequently
reduced production. The good news is that it is pre-
Implementation of good management practice at
harvest, storage and feedout is essential if dry matter
and nutrient losses are to be minimised and the risk
of aerobic spoilage reduced.
Choosing the optimum chop length is an important
factor in making good silage and often requires a
compromise between the ideal length for maximum
compaction and silage preservation and the ideal
length for good rumen health and cow productivity.
The advent of crop specific silage inoculants such
as Lalsil Maize and the discovery of a patented strain
of bacteria, Lactobacillus buchneri NCIMB 40788
make it easier to balance crop preservation with ani-
mal production and allow a chop length of 18-22mm.
Typically, high starch crops such as maize will fer-
ment rapidly in the bunker and achieve a stable fer-
mentation without an inoculant. However, it can be
susceptible to aerobic instability, or heating, both in
the bunker if it is not packed well, and at feedout.
Conventional silage inoculants will not prevent
spoilage as the lactic acid that they form can itself be
used as a substrate by the spoilage yeasts and moulds
that you want to control. However, L. buchneri
NCIMB 40788, the unique bacteria used in the spe-
cialist maize inoculant, Lalsil Maize, will inhibit the
spoilage organisms that cause heating.
The organism is so effective that it is also used to
preserve difficult high dry matter feeds such as maize
earlage and high dry matter whole crops.
Independent research recently completed by
Aarhus University in Denmark and published in the
Journal of Dairy Science found that L. buchneri
NCIMB 40788 doubled the aerobic stability of maize
silage compared to maize silage which had not been
treated with an inoculant and maize silage treated
with an inoculant which did not contain L. buchneri
Quantifying production losses from single ration
inputs is not easy to measure. However, independent
research conducted worldwide confirms that better
management of stored silage is key to avoiding sub-
stantial losses. Growing a good crop of maize is an
investment. Using a combination of correct harvest
date, an effective inoculant such as Lalsil Maize,
good sheeting and good bunker management will
make the most of that investment.

WEST OTAGO Ayrshire and Holstein
breeder Ken Eade started freeze branding
five years ago after four heifers ripped
their ear tags out on a netting gate the day after they
“The thing with ear tags is that the more cows you
milk the harder it is to identify them.” Ken said.
“We still put ear tags in, but if they come out now it
doesn’t really matter because they’ve got permanent
ID on their rump.”
“It works great for herd testing and it’s easy to see
when cows come in season because you’re normally
driving along behind them and it’s that end that you
see.” he said.
For the last three years Ken has had Stuart Makgill,
of NZ-Wide Freeze Branding, apply a permanent
freeze brand to all his heifers in July each year.
“We certainly recommend them to anyone,” Ken
said. “We found with Stuart, the brands were much
bigger and easier to read. He does a good job. He’s
very quick and very thorough and he’s always got a
good story to tell.”
