Where possible, we source our bulk raw materials locally, however there are many drivers in the background of our procurement process impacting what we can buy from where. We source our grains from New Zealand and Australia, whilst we source our proteins from New Zealand, Australia, and the northern hemisphere when necessary. The spread of these purchases can change between region, season, and year. Whilst we would love to be able to source 100% of our raw materials locally, there is unfortunately not enough to go around, or it is not available in New Zealand. Additionally, we make sure to purchase the highest quality raw materials we can, to make sure we are manufacturing the best products we can for your herds.

Bulk pellets

Quality milling and pressing equipment ensures ingredients are properly processed and thoroughly mixed. The pelleting process improves digestibility of the feed and reduces the risks associated with bacterial contamination of unprocessed feeds. Attention to pellet quality and durability improves both storage and transportation whilst minimising fines and maximising palatability.
We have many different bulk dairy pellet options both nationally and regionally. To help you make the right choice for your system, we have a team of Technical Sales Representative’s on the road, ready to assist you.

Seales winslow calf meal

We offer two options:

  • SealesWinslow Calf Max is our premium range, containing a 20% Muesli, 20% Pellet or a 16% Pellet option. This range contains our exclusive additive, NuStart® Evolution, which provides a prebiotic and our renowned unique flavouring. NuStart® Evolution helps increase appetite, and reduce scours, thus increasing daily liveweight gains. Calf Max contain a coccidiostat – Bovatec® 20CC.
  • SealesWinslow Rumatain is our economic option, containing a 19% Pellet, or a 17% Pellet. This Rumatain range does not contain NuStart® Evolution and has a slightly lower starch content than our premium range. However, it is still a tasty and effective product for growing your calves. Rumatain calf meal contain a coccidiostat – Bovtec®20CC.
Muesli 20% is often used as a starter meal for new calves, as the molasses helps the feed stick to their nose. Calves lick this off and love the taste which helps encourage early intake of meal. SealesWinslow Muesli has been specially formulated to be nutritionally balanced, and easily digested. However, pellets are also suitable to start calves on.
Calves need a certain amount of protein to grow. A higher protein percentage meal will result in more protein to support a fast-growing calf. This is especially beneficial if you are weaning your calves on liveweight targets rather than age. When fed a lower protein feed, they will need to eat more feed to supply the amount of protein needed to grow.
Due to the sticky nature of muesli (from the molasses) the best way to feed SealesWinslow Calf Max Muesli is small amounts, often. Large volumes, left over time can become compacted, especially when temperatures get colder, or it has been played with and slobbered on.
No. For more information on the ingredients in our calf meal, check out calf product pages on our website.
No. All SealesWinslow calf meal products contain a coccidiostat – Bovtec®20CC. This is an Ionophore, which is toxic to your monogastric family friends. Please keep your calf meal tucked safety away from hungry mouths it is not designed for.
Calf meal should be stored in a cool, dry space, away from direct sunlight and any risk of moisture. Calf meal can sweat when it is left in moist, warm conditions, which results in condensation inside the bags, and increases the risk of product going mouldy. The plastic pallet wrap wrapped around calf meal bags should be removed as soon as the pallet reaches its destination.
No, our bags are not waterproof. To keep our product fresh, the bags must be able to breath, and therefore moisture can get out (and in).
SealesWinslow calf pellets (range dependent), are packed in 20 kg or 25 kg bags, bulk bag (1Tonne) or in bulk with a minimum order of 3 Tonne. SealesWinslow Calf Max Muesli is available in 20 kg bags only.
