NUTRITION
Simple blend
(50% PKE, 30% Soya hull, 20% maize DGGs with added magnesium, calcium, and sodium)
NRM Dairy Standard Pellet Ingredients have been hammer-milled and conditioned with steam and pressure during the manufacturing process.
Baleage
Maize Silage
PKE
Variable depending on the quality of harvested crop and the ensiling process. Maturity of the crop, species harvested, and moulding can impact feed value.
Variable depending on the crop, height of cutting, ensiling process, use of inoculants and speed of use across the pit.
High lignin level. Energy level can vary a little depending on the fat percentage but generally a consistent feed.
Adding in the soya hull and maize DGGs decreases the lignin which increases the overall digestibility.
Usually adequate levels of macrominerals.
Low in Ca, Na and P. Supplementation required, especially when feeding over 3kgDM/day.
Good source of P but low in Ca and Na.
Added Ca, Mg and Na increases major minerals to support milk production.
Microminerals
Usually adequate but very variable.
Generally low
High in copper
Reasonable copper levels due to PKE content.
Trace element and vitamin premix added to reduce deficiencies

Cost per unit of Metabolisable Energy (ME)
Cost can vary and prices may inflate to $120-$150 during a dry period with increasing demand. May also be hard to secure during a dry period. 4.8-6.3c per unit of ME (based on 10 ME silage)
3.2c per unit of ME (based on 10.5 ME silage)
3.5c per unit of ME (based on 11 ME PKE)
4.1c per unit ME
5.1 - 6c per unit of ME (based on 12 ME pellet.) Macro and trace mineral supply improved which may cost more via other routes.
20% when fed on ground in paddock and up to 40% in poor conditions.
5-25% when fed in troughs. 25% when fed in the paddock and up to 40% in poor conditions.
Fed in-shed <5%. Fed in troughs in paddock 1020%. Fed in paddock on the ground 30-40%.
Fed in-shed minimal <5%. Fed in troughs in paddock 10-20%. Fed in paddock on the ground 30-40%.
Minimal due to pelleting and emphasis on minimising fines. <5% when fed in-shed.
A good option for filling a feed deficit but quality of purchased in silage can be variable and prices tend to increase during a dry period. The true cost of energy consumed should be considered.
A good option for filling a feed deficit but does have some downfalls such as low in protein and low in macrominerals so requires balancing for lactating cattle. Not available in all regions of NZ.
A moderate fermentable energy option, good at filling a feed deficit â&#x20AC;&#x201C; however the amount in the diet needs to be capped for Fonterra suppliers due to Fat Evaluation Index restrictions. Good for supporting cow condition.
The next step up from straight PKE with a higher fermentable energy level due to the inclusion of soya hulls and maize DGGS. More balanced for lactating cows in terms of macronutrients. A good option to fill a feed deficit in a dry period to keep FEI levels lower.
A good option for an in-shed feed system. High energy due to the presence of grains. Balanced in terms of macronutrients and micronutrients. Low wastage and feeding-out costs when fed in-shed, available in a range of formulations to meet needs.
Make sure you check quality of baleage and avoid poorly fermented or mouldy silage.
If feeding high levels make sure to balance the diet for protein, Ca, Mg, Na and P. Not easily traded once in the pit as deteriorates rapidly if moved.
Keep an eye on your FEIs if a Fonterra supplier. If feeding out in the paddock, make sure there is adequate trough space.
If feeding out in the paddock, make sure there is adequate trough space. Easy to adjust formulation to meet herd needs.
Make sure animals are transitioned onto the pellet sufficiently due to the grain content. Useful way to deliver additives such as bloat remedies and zinc against facial eczema.
