Several weeks back I was outside in
shorts and a t-shirt dealing to some
overdue fencing repairs, while others
further south have been bombarded
with sleet, rain and snow. One thing is certain in my travels
around the country, feed covers in many regions are looking
scarce. While it’s natural at this time of year, the impact of
the autumn drought will have placed an even greater toll on
pastures and stock.

Getting the best kill
from glyphosate
Direct-drilling
Considerations for sowing in pastoral situations.
PGG Wrightson’s Technical Field Representatives are often called
on to troubleshoot crop establishment failures. Direct-drilled
crops and pastures contribute a disproportionate number of
these situations. In many cases these establishment failures
were preventable.
There is a significant movement towards pasture renewal
practices that involve direct-drilling. And for good reason.
Repetitive cultivation of at-risk soils is detrimental to soil health
and productivity.
But let’s not forget that cultivation also has benefits. In pastoral
situations, where soils are exposed to treading damage from stock
(pugging) and the build-up of thatch, pasture pests and weeds,
cultivation has many advantages.
Some key considerations for successful establishment of
crops and pastures using direct-drilling include:
>> Know your paddock. Ensure the paddock is acceptable for
direct-drilling. Pugging damage, high pest or weed pressure
and excess thatch or surface residue may necessitate
cultivation.
In direct drilling situations it is essential to
absolutely nail the spray-out. Li-1000™ and
Hammer® from Etec™ Crop Solutions are
great companions to glyphosate, with no
plant back periods.
Li-1000 is a multipurpose adjuvant that aids with spread,
penetration and translocation of glyphosate within the
plant. Unlike organo-silicone spreaders, which work by
stomatal uptake (well suited to use on plants with large
stomata, e.g. brushweeds), Li-1000 works by lifting the
waxy cuticle, enhancing penetration of glyphosate where
stomatal uptake is restricted. This is particularly useful for
aiding the kill of grasses which have small stomata, including
perennial ryegrass.
Hammer is a companion herbicide that provides more
effective control of broadleaf weeds when added to
glyphosate. Hammer improves the control of hard to kill
weeds including mallow, storksbill, alligator weed, stagger
weed and nettle, desiccating mature weeds and increasing
the speed of kill. Hammer has no plant back periods, allowing
you to direct-drill the crop anytime following application.
For best results at spray out, tank mix the recommended
rate of glyphosate product with both Li-1000 and Hammer,
and consider the addition of an appropriate insecticide for
springtail control. For more information talk to your local
PGG Wrightson store or Technical Field Representative.

>> Prepare the paddock well. Without cultivation to aid pest
and weed control, agri-chemical selection and application
must be accurate. A plan is required prior to spraying and
sowing to ensure a good kill and minimise trash or residue
at drilling.
>> Monitor! Without cultivation, weeds and pests can build up
very rapidly. Monitor regularly and thoroughly from drilling.
Talk to your local PGG Wrightson Technical Field Representative
in the lead up to spring planting and ensure you have ticked all
the necessary boxes.

Hammer®
Improve grass and broadleaf kill
this spring. Li-1000 dramatically
reduces drift and more spray
lands on target. Once on the
plant, penetration is rapid and
the herbicide becomes rainfast
in 30 minutes.
With no sowing restriction,
Hammer is best used when a
fast turnaround is required for
earlier crop production. Use with
glyphosate for faster and better
broadleaf control pre-sowing of
any crop.

Optimising spring pasture growth
Drought conditions made last season
a particularly difficult one for dairy
farmers. If your pastures are still
recovering from this, you can help the
rebuilding process by ensuring soil
nutrient levels are right. Since your
fertiliser spend makes up a significant
portion of a farm budget, it is worth
taking a measured approach to
developing and implementing your
fertiliser programme, to ensure you
gain the greatest value from it.
>> Plan first. This should include regular
soil testing.
>> Focus on the key nutrients:
phosphorus (P), potassium (K) and
sulphur (S).
>> Use nitrogen strategically to boost
pasture to meet your production
goals.
A soil test, taken every one to two years,
will give you a good idea of current soil
nutrient levels, and if you carry it out
regularly, you will also get an idea of the
04
trends in nutrient levels. The table below
shows you the optimum levels to aim for.
The phosphorus levels shown in the
table assume you are achieving average
production for your area. If you’re aiming
to be, or are, in the top 25% for milksolids
production, then you may want to
increase your Olsen P levels to 30-40
(ash and sedimentary soils), or 45-55
(pumice and peat soils). However, you
need to be sure you are going to use the
extra pasture produced to increase your
milksolids production so you can justify
the extra expense.
Cold, wet conditions over winter may
have caused a drop in your soil sulphate-S
levels; your soil testing will indicate
whether this is the case. Good levels of
sulphate-S will help your pasture respond
to your spring nitrogen applications and
will also encourage clover growth.
If your K levels are low, apply it post
calving; this way you will minimise any
animal health issues and the K will be

available during the period of active
pasture growth. You should also monitor
paddocks regularly used for silage or
hay, as K will be removed each time
a paddock is harvested. In contrast,
effluent paddocks may have high levels
of K.
An application of nitrogen is often
useful in the second round after calving.
It is important to remember that the
response will occur three to five weeks
after an application. During spring,
when growing conditions are good,
individual applications can increase
up to 40-60 kg N/ha. However to gain
maximum benefits, you need to make
sure you are able to utilise the extra
feed effectively.
The timing of applications is also
important. The soil shouldn’t be too
cold (<7°C) or waterlogged. You need
rain (at least 10 mm in the 24 hours after
an application) to wash the nitrogen
into the soil where it can be used by
plants. If conditions are uncertain, use
SustaiN® Green rather than n-rich urea.
Your PGG Wrightson or Ballance
Representative can help you put
together a fertiliser programme for
your farm that ticks all the boxes.

Fodder beet – a high yielding feed option
Fodder beet has been grown in New Zealand for many years
but has recently increased in popularity as it can give very
high yields, with high energy (ME) levels, when compared with
other winter brassica options. Fodder beet yields vary greatly,
ranging from good crops in Southland reaching 20t DM/ha,
to crops in parts of the North Island reaching 40t DM/ha.
Environments with increased growing degree days will have
the potential to grow larger crops than other reduced growing
degree day areas.
Fodder beet is not a brassica so it does not get common brassica
diseases like club root or dry rot; and once established it is tolerant
of many insects that attack brassica crops.
The key to the successful management of fodder beet is ensuring
that no short-cuts are taken. There are three vital steps that will aid
the fodder beet in reaching its full potential; good soil preparation,
accurate sowing, and control of weeds and insects.
1. Good soil preparation. A soil test should be taken at least six
months before planned drilling as the ideal soil pH for fodder
beet is 6.2. Fodder beet yields are also sensitive to potassium,
sodium, chloride, and to a lesser extent, phosphate and
nitrogen. Most of the fertiliser should be applied at the time
of sowing, with some further side-dressing required before
bulbs begin increasing in size. Fodder beets do not like
compacted or damaged soil.
2. Accurate sowing. The use of a precision drill and modern,
true mono-germ seed is vital in ensuring even plant spacing
to maximise uniformity and reliability of the estimated yield
per hectare. An even germination of plants will increase the
options for weed control post germination.
3. Weed and insect control. Weed competition can reduce
fodder beet yields dramatically so early chemical application
is required. Speak to your local PGG Wrightson representative
for advice and look to put a plan in place well before drilling, as
this will help ensure a successful establishment.
Established fodder beet plants are very tolerant of insect attack,
but during establishment, insects such as adult grass grub,
cutworm, springtails and Nysius can cause irreversible damage
to the plant. Frequent crop monitoring will ensure that any insect
issues are identified early and able to be controlled before they
have a major effect on the crop yield.
Once the crop has relative canopy closure and bulbs start to
expand, there are few insects that can reduce crop yield. Powdery
mildew and rust can affect fodder beet, with overseas sugar beet
literature suggesting that powdery mildew can significantly
reduce the final yield of the crop. There have been a few isolated
cases of bulb diseases affecting yields. To reduce the risk of this it
is recommended that fodder beet is not grown continuously in a
paddock without the use of break crops for more than one year.
Speak to your local Agricom representative to discuss the
benefits of fodder beet use on your farm.

Lion® 490 DST – manufactured exclusively
for PGG Wrightson
Farmers getting organised for spring spray out ahead of crop or
pasture renewal have an advanced new option at hand with this
month’s launch of Lion® 490 DST glyphosate herbicide.
Available only from PGG Wrightson, this new formulation of the
very successful Lion® 470 DST combines the proven performance
benefits of dual salt technology with a higher strength glyphosate
loading for even better results on farm.
It’s the only formulation of its type available in the New Zealand
market, and it is manufactured exclusively for PGG Wrightson by
Nufarm New Zealand.
Like its predecessor, the new Lion 490 DST provides farmers with
a cost effective mid-strength glyphosate developed for more
reliable performance in challenging New Zealand conditions.
The patented formulation features new generation potassium
and ammonium salts for increased product solubility. This in turn
allows for a higher loading of surfactant per litre of product.
Lion 490 DST can be used to control a wide range of common
annual and perennial grass and broadleaf weeds.
Before spraying, farmers should check to see what species of
weeds are present, and in what numbers, and adjust herbicide
rates accordingly.
Plants need to be actively growing for the chemical to be
translocated through plant tissue to kill the roots, and where they
are spraying out short term or perennial ryegrass, farmers should
always add Pulse® Penetrant.
Lion 490 DST comes in 20 L, 200 L and 1,000 L drums. For more
detail on using this higher strength formulation as part of your
spring herbicide programme, talk to the team at your local PGG
Wrightson store.
ARTICLE SUPPLIED BY NUFARM NEW ZEALAND
More surfactant increases the penetration of the
glyphosate molecules into the plant, and improves
herbicide performance, explains Cynthia Christie, Nufarm
Development Specialist.
Farmers may not be able to see the technology inside
the new formulation but what they will see is faster
brownout, easy mixing, good solubility and reliable
performance, she says.
At this time of year, when paddocks are being prepared for sowing
summer crops such as maize or forage brassicas, Lion 490 DST’s
higher strength and superior technical attributes will help farmers
get the best out of their spring sowing.
“A successful crop starts with a good, clean spray out, and the
same applies in areas where farmers are spring-sowing new
pasture.”

Winter sheep management
Late pregnancy management of ewes
You will have a gut feel for feed availability and the body condition of the ewes going
into late pregnancy on your farm. If you are unsure, contact your local PGG Wrightson
Technical Field Representative to help you develop a quick feed budget. Making efficient
use of the feed on your farm involves identifying which ewes will benefit most from
increased feeding and which ones can be restricted.
Production improves as body condition increases to BCS 3 (e.g.
fertility, fecundity, milk production). After this, putting more
condition (body weight) onto ewes may not improve performance,
but it can be used as an energy reserve in late pregnancy when a
multiple bearing ewe cannot eat enough grass to fulfil her energy
needs. As many ewes will be in late pregnancy (or lambing), the
only ewes that can be restricted are the singles and those that
become pregnant in the second cycle of mating. Ewes in better
body condition are more able to buffer against changes in feed
supply than those in light body condition.

60 kg ewe at breeding, approximate kgDM/day required
(12MJME/kg grass).
If feed during pregnancy has been restricted, it is even more
important to feed the ewe optimally during lactation, i.e. minimum
pasture covers of 1200 kgDM/ha. On hilly terrain this residual must
be higher as the ewe is expending energy grazing this feed – it
takes more effort and time. Offering more than 1800 kgDM/ha does
not increase their intake.
The second injection for these ewes, or the annual booster for
previously vaccinated ewes, needs to be timed to transfer the
maximum number of antibodies into the colostrum. NILVAX®
induces a greater antibody production response in the ewe which
can be beneficial, allowing earlier vaccination (up to six weeks
prelamb), providing more antibodies for multiple suckling lambs
to share, and extending the protection period for the lamb (up to
16 weeks).
MULTINE® can be used up to four weeks prelamb and provides
up to 12 weeks protection for the lamb. Vaccination too close to
lambing can be metabolically dangerous for the ewe as taking
her off grass for even a few hours can induce sleepy sickness and
hypocalcaemia. For these reasons it is best to give the booster
vaccination three weeks prior to lambing. Ewes lambing in the
second cycle can be vaccinated and set stocked later, spreading
the workload and also saving feed (the later lambing ewes will eat
as much as the lambing ewes if you offer it to them, whether they
need it or not!).
If prelamb drenching is required it may be given earlier or at the
same time as the vaccination. Ewes that are under increased
nutritional stress and a high parasite challenge may benefit from
treatment at mid pregnancy, e.g. scanning time.
For all your prelamb drench and vaccine requirements, talk to
your local PGG Wrightson Technical Field Representative or
store today.

Prelamb vaccination to prevent clostridial deaths in the ewe,
and to provide antibodies in the colostrum milk, is now standard
procedure on most farms. The timing of the vaccination in respect
to the lambing date is critical for success. For ewes that have an
unknown vaccination history, two injections are required with
these being no closer than three weeks apart.

Docking/tailing
Top tips to consider when docking/tailing
1. Blowfly prevention product choice is based on the length of protection required.
2. Vitamin B12 is likely to be more effective at docking than weaning.
3. Sheep administered a long acting drench at scanning can be given an exit drench
(Zolvix®, Pyrimide® or ALLIANCE®).
4. Keep all equipment as clean as possible.

CLiK® Spray On – putting the worry of flystrike behind you
Flystrike is the second most costly
parasitic disease of sheep in New Zealand,
ranking only behind gastro-intestinal
roundworms in economic importance.
Estimates are that flystrike costs
the New Zealand sheep industry
approximately $37 million per year,¹ with
those losses coming from deaths, cost
of treatments, and lost meat and wool
production. Research has shown that
even relatively small strikes can cause a
marked appetite loss in the struck animal
with a resulting loss in weight. Recovering
this lost weight can take significant time.²
Anecdotal evidence suggests that ewes
and ewe hoggets struck in late summer/
autumn are far less likely to get in lamb
than non-struck animals.
The key to minimising the losses caused
by flystrike is to adopt a preventative
treatment approach using fully effective
products. A preventative approach
means that treatments are applied before
expected fly activity, rather than waiting
until animals are getting struck before
treating – these are referred to as reactive
treatments and production losses will have
already occurred.
term flystrike protection – CLiK Spray On.3
CLiK Spray On is a low volume spray on
containing 50 g/L dicyclanil; an insect
growth regulator (IGR) developed by
Novartis Animal Health specifically for the
prevention of flystrike on sheep. A recent
survey of field strains of European and
Australian Green Blowflies in New Zealand
found no resistance to dicyclanil, while
strains resistant to another commonly
used active ingredient, triflumuron, were
widespread in parts of the North Island.4
CLiK Spray On has an advanced ‘RainLock™’
formulation, which allows the active
ingredient to bind strongly into wool
grease, resisting the effects of washing out
under wet conditions. Other water soluble
formulations (e.g. Vetrazin® Spray On) bind
more loosely to wool fibres and are more
susceptible to washing out under rainfall.5
protection. Feedback from farmers in
New Zealand and overseas confirms that
CLiK Spray On allows farmers to put the
worry of blowfly strike behind them.
The correct applicators must be used
to ensure you get the best results from
CLiK Spray On. Novartis Animal Health
has worked with New Zealand drench
gun manufacturer, Simcro, to develop
two applicators – a 10 ml gun specifically
developed for applying docking
treatments, and a larger 15 ml gun for
applying whole body treatments.

Why treat dairy cows in early lactation
with Cydectin® Pour-On
Internal parasites have been shown to cause a reduction in milk yield in lactating dairy cows.1,2
In early lactation, cows are in a negative
energy balance, stripping body fat to
meet the demands of milk production.
This means there is less energy available
to fuel the cow’s immune system. Parasite
larvae can therefore become established
within the gastrointestinal tract. The
question then arises, is it cost effective to
remove these parasites, and if so, what
is the best product to use and way to
administer it?
The aim of treatment is to prevent the
establishment of parasite larvae for as
long as possible until the body’s immune
system is capable of achieving this for
itself. Cydectin Pour-On for Cattle and
Deer has the longest persistent activity
claims of any endectocide in New Zealand
against the main production limiting
parasites of adult cattle – Ostertagia
and Trichostrongylus. It is therefore
the treatment of choice for cows in
early lactation. As a pour-on it also has
the advantage of nil milk and meat
withholding. Recent work by Dr Dave
Leathwick³ highlighted that there was
no difference in the ability of Cydectin
Pour-On to kill Ostertagia, whether it was
given by the pour-on, injectable or oral
route.
The benefit of treating dairy cows with
Cydectin Pour-On can be an increase in
milk production of 3.5% when treated
in early lactation. It can also significantly
increase milk protein levels.⁴ The exact
return for individual farms will vary
depending on a number of factors, such
as level of feeding, body condition of the
cows and their genetic ability to strip
body fat in favour of milk production.
As a general rule, high producing cows,
first calving heifers, low body condition
animals and those on poorer feeding
levels, will benefit the most from
drenching during lactation and hence
give the best return on investment.
However, to help reduce the risk of
developing drench resistance, not all
cows should be treated within a herd.

Cydectin Pour-On, visit your local
PGG Wrightson store or talk to your local
Technical Field Representative today.

Calf drenching – key
points to consider
Giving your calves a good start in life is
important. Poor growth over the pre-weaning
period is seldom caused by internal parasites
(worms), but more commonly due to incorrect
feeding calculations, i.e. the calves are being
underfed for the required targets.
Mineral deficiencies in this period can be important so consider
supplementing with selenium and vitamin B12. Clostridial
vaccinations are important too; MULTINE® 5-in-1 is administered
when calves arrive on-farm or when they are one week old, and
are boostered four to six weeks later.
When calves have been eating grass as the main part of their
diet for three weeks and are a minimum of 100 kg liveweight,
oral drenching with ALLIANCE® can begin. Prior to this the worm
burden is unlikely to be significant, abamectin drench can be
toxic and the oesophageal groove directs the drench into the
abomasum instead of the rumen, reducing the time it can be
absorbed (the drenches do not kill on contact but rather their
metabolites are secreted into the gut mucosa and fluids).
Drenching calves at 28 day intervals helps to reduce pasture
contamination with worm eggs and is also a good time to check
liveweight gains. It is very important to use a measuring cylinder
to check the accuracy of your dose setting and also to weigh the
calves, drenching to the weight of the heaviest calf.

Feedgrade molasses
>> Complementation of high fibre (NDF) diets. The zero NDF
content of molasses balances high NDF feeds such as poorer
quality pasture, silages and high NDF by-products such as PKE.
Feedgrade molasses, a by-product of the manufacture of raw
sugar, contains the highest level of water soluble carbohydrates
(WSC) of any of the common by-product feeds. Molasses
complements dairy diets based on pasture, silages and grain,
supporting more milk solids and better body condition score
for molasses-fed cows. Additional benefits of molasses include
better consumption of less tasty feeds, settling of dust within
shed feeding systems, better cow flow through the shed,
enhanced digestibility of PKE and potential dilution of high
dietary protein levels.
>> Tasty feed. Cow flow into the shed improves when molasses
is offered, reducing the need to chase cows in from the
yard. In-shed molasses feeding helps with training of heifers
coming in for the first time, and for cows entering a new shed
environment. Exit laneway feeding helps cows quickly exit
the shed.
Benefits include:
>> 3.5% more milk solids. In a 2002 Massey University study
undertaken at AgResearch’s Flockhouse dairy farm, 34
pasture-fed cows offered 500g of molasses per cow per day,
produced significantly more milk per cow than 30 control cows
fed only pasture (Figure 1). Molasses-fed cows produced 3.5%
more milk solids per cow during the first 120 days of lactation.
>> Better body condition score. Higher body condition scores
support more days in milk, more milk solids next season, and
better six week in-calf rates.
>> Better serum magnesium status. Magnesium absorption from
the rumen was improved for molasses-fed cows, compared
with cows fed only pasture (Figure 2).

compared with cows fed pasture only (Massey University, 2002).

>> Better consumption of dry, dusty feeds. Dry cereal grains,
blends, protein meals and pelleted feeds will benefit from
molasses added to dry feeds in the bail. Better acceptance of
dry feed means a higher proportion of cows will consume the
mix on offer and cows will eat feed more quickly after calving.
Molasses helps mask the flavour of minerals added to dry
feeds and helps settle dust, improving the shed environment
for cows and staff.
>> Tastier wagon mixes. Within a partial mixed ration (PMR) or
total mixed ration (TMR), feedgrade molasses improves better
overall acceptance of the mix. This is important if silages are of
less than ideal quality or to mask the inclusion of unpalatable
additives.
>> Dilution of crude protein (CP) intake. Feeding molasses
dilutes total dietary CP content, potentially reducing losses of
nitrogen to the environment.

Animal management
Do you know how to feed your bugs?
Strategies to
consider in optimising
milk protein yield
The first thing we need to consider in ruminant nutrition is
that we are actually feeding two animals:
1. The bugs in the rumen, and
2. The cow.
Woolover lamb covers
save lives and money
As lamb prices return to previous levels,
sheep farmers should be planning towards
maximising the survival of the new season’s
lamb crop.

spore centre. Photo by Mel Yokoyama and Mario A. Cobos.
The first step to good nutrition is to fully feed the cows;
e.g. a 500 kg lactating cow can eat 4% of her body weight in
dry matter; that means 20 kg DM down her throat every day.
We can improve production simply by ensuring the cows have
enough to eat!
The next step to good nutrition is to balance the nutrients.
The rumen bugs like to have their ‘meat’ (protein) with their
‘potatoes’ (carbohydrates) on the same plate. During the spring
flush we may have too much ‘meat’ from the protein in the grass
and not enough carbohydrate to provide energy for the bugs.
This is when grain can help.
By meeting the microbe energy needs, microbial populations
increase so the bugs can work more efficiently at extracting the
energy in the grass to feed the cow. More microbes also mean
more microbial protein, which provides the protein the cow
needs to make milk protein.
It makes sense to ensure we are feeding the bugs a balanced
diet so they can help the cow meet her needs.
For all your grain requirements talk to your local
PGG Wrightson Technical Field Representative or store today.

Woolover lamb covers can play a major part in ensuring survival
of “at risk new borns” as well as assisting the lambs to reach target
weights earlier.
The nature of the country and accessibility, breed of sheep,
paddock history, pasture cover and availability of labour who
understand normal lambing behaviour with the minimal
disturbance, are all factors as to whether to shepherd or not.
Remember a shepherd with a bike/utility/on foot has only to
fit the Woolover lamb cover to at risk new borns. Simply fit the
cover/covers and move from the birth site with the knowledge
that these lambs should next be seen at docking time.
Farmers can expect an extra 650 g live weight in covered lambs
over three weeks, versus uncovered; particularly in cold wet windy
weather. With a current schedule of approximately $5.00 kg, the
extra 650 g liveweight is worth $1.60 which pays for 40% of the
cost of the cover. Plus, you have the satisfaction of reducing the
risk of lambs dying from hypothermia by 85%.
At $3.85 plus GST per cover, covering at risk new borns makes
good financial sense.
How many covers do you need? We suggest a minimum of 10%
of the flock number, i.e. 3,000 ewes will need 300 covers. This is
because storms nearly always arrive at peak lambing and the
twins and triplets are the most at risk. Taking these factors into
account, a big day’s lambing could be 10% of the flock or more.
300 covers cost $1,200 so we need to save just 14 lambs to cover
this investment.

cover requirements today.
