Options to help close a fodder gap: 1. Agronomic strategies to increase home-grown forage A critical determinant of drought survival will be rapid return to as much pasture in the diet as possible. Many farmers will have rain as seasonal outlook is strengthening. Optimising home-grown forage options is likely to: Be more cost effective and profitable than purchased feed Reduce pressure on internal inventory Be nutritionally superior Reduce pressure on overall supply Each shift of 1 tonne DM of purchased to home grown feed should represent a saving of $100-200 per tonne and an improved quality on most purchased forage sources Responses to agronomic strategies will be linked to rainfall. Cashflow on many farms will be key issue. Many farmers may need coaching on key spend and best/most cost effective and rapid response Need to consider risk management and promote a “portfolio approach” ie. Spread the risk Many perennial pastures will have died or be severely thinned Making the most from moisture Plant aggressively as opportunity arises- waiting till conditions are perfect will miss early opportunities- sow a little more on each rain event to manage risk- once moisture profile is full sow everything Consider sowing additional dryland areas if available- can be used as pasture early and diverted to stored feed if season appropriate Soil test and apply nutrient accordingly Fertilise- hold nitrogen inventory on farm to pick up rain as it falls Timing is everything. Keep “rolling the dice” on each rainfall eventDon’t put all your eggs in one basket - a “portfolio approach” to pastures is essential. Irrigation entitlements uncertain: Use of short season crop with rapid winter growth transition to high WUE summer crop Use of longer season pasture/crop to capitalise if season is good and optimise spring WUE Match crop with security of paddocks Look at sowing options that increase early feed cost effectively. Consider oversowing increased areas of permanent pastures to improve water and fertility responses in event of some irrigation Carefully review merits of sowing perennial species/cultivars due to slowness to first grazing, low early season yield and risk of reduced summer water allocations Sow dryland areas for forage crop or winter pasture Increasing early growth: Co-plant with cereals to increase early feed production on late plantings Use cultivars/species with rapid early growth as part of portfolio approach Increasing planting rates to promote early plant density - doubling rates of ryegrass seed can produce extra feed for <$100 a tonne dry matter Plant early as possible if moisture allows – two week delay can reduce winter yield by 30-70% Strategically use nitrogen to boost winter forage and improve returns from moisture and seed o 5-10kgs DM/kg N applied (possibly higher in newer, high density pastures) o Even at $750 a tonne Urea, and a winter response of 5kgs dry matter per kg nitrogen (low end of expected range), the cost of the extra feed is 32 cents / kg DM – still favourable compared to purchased supplements o Many farmers are still using N application rates that are well below optimal Soil test to screen for other key nutrients o Many will have accumulated nutrient due to crop failure, feeding out or natural breakdown o Others may have been depleted due to cashflow failure Manage pastures for survival and yield Quantity far more limiting than quality on most farms until early spring at least The key to pasture yield early in the season is not what you take off a paddock, it is what you leave on it! Target residuals of at least 1400kg dm/ha or at least 5cm through winter. Grazing at higher than normal pre and post grazing heights will help increase daily NDF intakes. Let pastures grow and farm for residuals Back-fence Need to consider possible pasture toxicity problems, especially nitrate toxicity. (Others - oat sickness, grass tetany, bloat, ruminal acidosis Appropriate preventive strategies include: Nitrate testing- soil/plant Test grazing Slow introduction of hungry stock Monitoring Key messages: If farmers are lucky enough to have pasture options, they should manage wisely!Make the most from moisture - rapid and anticipatory response to rain is critical Nitrogen application is good value. Don’t be put off by increased urea prices. Quantity is far more limiting than quality on most farms until early spring at least. Let pastures grow and farm for residuals. A “portfolio approach” to pastures is essential 2. Feeding strategies to stretch out existing fodder reserves High NDF / low starch by-products such as Palm Kernel Meal (PKE) should be considered as a forage substitute rather than a grain/concentrate substitute – ie. “forage extenders”. Advantages of “forage extenders”: Are useful inclusions in late lactation diets (less suitable for fresh cow / early lactation diets. Also easily fed to dry cow and heifers Low in starch, so don’t contribute to ruminal acidosis Flexible. Can generally be fed ad lib. Can be easily fed out (hayshed to front-end loader to trough), or incorporated in grain/concentrate rations Challenges in using “forage extenders”: Have a very small particle size, so they don’t provide physically effective fibre and don’t obey NDF intake rule of thumb (intake = 1.2% of bodyweight as NDF). Despite this, they contribute chemical NDF which can help you get away with a high risk Forage / Concentrate ratio Consistency of supply eg. PKE Feed specifications for each product are not readily available and may vary considerably depending on their source and the level of control over the manufacturing process. PKE’s estimated Metab. Energy by chemical analysis are probably overestimated. DDG’s protein content is poorly available Mycotoxins can be a problem if weather changes Are more difficult to make work in a diet as the quality of the forage used declines Cost per unit energy and protein The nutritional specs. of forage extenders products vary. Useful to rate feeds low, moderate, high in terms of digestability and effective fibre level, as well as quote DM, ME, CP, NDF and ADF values. Maximum feeding levels may also be limited by animal health concerns or chemical residue concerns. There is very little scope for feed manufacturers to supply low starch / high fibre concentrates for feeding in the bail or paddock - suitable by-products are being fully utilised and long fibre sources cannot be used by most mills. Wheat is the easiest grain for home mixers to buy. Other grains are very difficult to source. Management practices to reduce forage wastage rates: Even the best feeding management system will result in a 5% forage wastage rate. Feeding on the ground in the paddock can result in wastage rates in excess of 20% Try to keep as much forage in rings and troughs as possible to minimise wastage Key messages: Forage extenders substitute for forage (fibre), not grain/concentrates (starch and sugars)forage extender products have supply challenges“Oils aint oils” – the nutritional specs. of forage extenders products varyWhen considering forage extender products, bear in mind their digestibility and effective fibre levelWheat is a great feed that is easy to buy – learn to use it safely and maximize the benefit from itWastage of fodder is unacceptable under the current circumstances, yet on some farms, > 20% of fodder is wasted 3. Strategies to reduce animal demand for fodder Priority should always be given to the fresh cows / early lactation cows. Options include Cull empty cows Dry stale milkers off Agist heifers Dry cows can’t be allowed to lose excess body condition. Young stock cant be allowed to suffer severe growth checks or suffer lameness / other problems which compromise their value as herd replacements. If not economic to continue to run heifers at 30% replacement rate, can this be wound back? Feeding grain/concentrates to dry cows and young stock is an option that many farmers should use (even in the bale between milkings if convenient) Culling cows – first choice is empty cows, then low producers. Option to milk cows longer should also be explored. Must always bear in mind the future impacts of culling decisions on the farm business. May be worth exploring agistment options. Eg. Park heifers in Mallee on wheat crop. Farmers need to appreciate that the nutritional requirements of dry cows go beyond just maintenance. Must also factor in nutrients for foetal growth and udder development. Farmers need to understand daily Dry matter requirements and ME requirements of all the different classes of animal (Look-up table) Key messages: Be conscious of future impacts of culling decisions on the farm business Consider culling and early dry off if forage reserves are short Don’t drop the ball through the dry period. Is an opportunity to feed dry cows some grain (through the dairy if necessary) Look for any agistment options Day-to-day feeding management The principle should be get as close to a TMR system as is reasonably possible – little feeds often throughout the 24 hours of the day to maintain a stable rumen environment. If you have a mixer wagon, the focus is on managing wastage and juggling different feedstuffs. If you don’t have a mixer wagon, then a key focus should be the timing of feeds. Make sure cows get to forage quickly after consuming grain/concentrate in the bale. Avoid holding cows back after milking. Try to maintain a routine that cows get used to – cows don’t like surprises Ensure adequate feed and water space. Rings and troughs. Fresh cows / early lactation cows are the highest priority. Is difficult for split calvers to manage these animals ideally without running two groups. Key messages: Timing of feeds is important to maintaining as stable a rumen as possible Maintain a daily routine Give priority to fresh cows / early lactation cows
