So with that in mind, in this month’s issue we pre-empt the coming spring season with information on how to make the most of spring pasture growth and cropping options. We are fortunate to have recently secured the services of Andrea Murphy B.Sc. (Agr) M.Sc. NZARN. Andrea’s role with PGG Wrightson is to provide technical support to our dairy representatives and customers. Andrea talks about the various strategies for optimising milk protein yields – turn to page 12 for this article. This month we also have an informative article by our in-house Vet, Andrew Dowling, on the management of pregnant ewes, plus key points to consider when drenching calves and top tips for docking.

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. ARTICLE SUPPLIED BY ETEC CROP SOLUTIONS
>> 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. Richard Brenton-Rule B.Hort.Tech (Hons) Technical Specialist – North Island Agronomy PGG Wrightson
Li-1000™
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. AUGUST 2013 |

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. ARTICLE SUPPLIED BY BALLANCE™ AGRI-NUTRIENTS

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. ARTICLE SUPPLIED BY AGRICOM

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. Four weeks pre lambing

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. Andrew Dowling BVSc Technical Expert Animal Health PGG Wrightson
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. Talk to your local PGG Wrightson team for further information about CLiK Spray On and all your docking/ tailing requirements. ARTICLE SUPPLIED BY NOVARTIS ANIMAL HEALTH (AHP3 Approved 225)

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. For further information or to purchase 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.

Nutrition
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). Figure 1.

>> 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. Product standard specifications Dry Matter (DM)

Nutrition
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.

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. Andrea Murphy B.Sc. (Agr) M.Sc. NZARN The Dairy Nutritionist PGG Wrightson
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. Visit your PGG Wrightson store to secure your Woolover lamb cover requirements today. ARTICLE SUPPLIED BY WOOLOVER LTD
