See How Composting Barns Are Transforming Kiwi Dairy Farms

The 7 Must-Haves
for a Healthy, Productive Composting Barn

These seven essentials are the backbone of every Aztech Composting Barn designed so your herd thrives and your barn delivers year after year

1. Correct Space Allowance
   Gives every cow room to rest, reduces stress, and ensures bedding composts properly.
2. 600mm Bedding Depth
   Thick organic bedding keeps cows comfortable and supports healthy composting.
3. Daily Tilling
   Mixes effluent and bedding to aerate, keep surfaces dry, and maintain cow comfort.
4. Ventilation & Airflow
   Removes moisture, lowers barn temperatures, and keeps bedding dry year-round.
5. Shade & Sun Protection
   Reduces heat stress so cows stay comfortable in every season.
6. Rain Protection for Bedding
   Prevents sodden bedding, reducing health risks and keeping cows cleaner.
7. Bird-Proof Roof Structure
   Stops contamination from droppings, protecting herd health from disease.

Case Study
Rob Little
Grey Valley, West Coast, NZ

Rob is passionate about the wellbeing of his cows and their comfort was a key motivator for him. Like many others, Rob also wanted to protect his pastures and the best way to do that is get his cows off pasture and under cover in an Aztech Composting barn.

Rob is a great example of how smaller farms can see the benefit of these barns rather than the common belief that they are for the "Big Boys".
