Along the way to Oamaru we passed
the Waitiki Dam, which is the first power station on the Waitiki River. The
Waitiki plains changed from sheep to dairy production in recent years. We then
went on our way to Oamaru. Oamaru is the largest town in North Otago and is
home to some of New Zealand’s best 19th century architecture,
including a Victorian Precinct. Oamaru is a town that still reenacts its
heritage through numerous festivities where the townspeople are seen dressed in
garments from the 1800’s. The town is split into the South and North sides. We
were able to see numerous buildings that were built in the 1800’s and that are still
being used and preserved. The buildings were made of local stone found in
Oamaru. This town is especially interesting because it is known as the steam
punk capitol of the world. Throughout the town we were able to observe the
numerous pieces of welding artwork that is composed of scrap metal. A lot of
the students grabbed lunch at local cafes and restaurants, trying to consume as
much local food as possible before our departure tomorrow. Some shops that were
found in the town included a Saddle Shop and numerous souvenir shops. Students
were also able to walk to the harbor on the Pacific Ocean and enjoy the view.

We then headed to visit Ard and
Wilma Van Leeuwen’s dairy enterprise, which contains over 24 milking robots.
The enterprise consists of twelve dairy farms which are owned by the couple,
but have a ranging variety of management. Some are managed by contract milkers,
50/50 sharemilkers, and family members. Overall, the enterprise consists of
12,000 head of Holstein, Jersey, and Kiwi cattle on over 7,000 hectares. Some
of the dairies are pasture based with the New Zealand normal setup of milking
cows in a rotary milking shed. However, they have chosen to experiment with
conventional ways of dairy farming by housing milking cows on the farms in barns. Three of these twelve farms are adopting new
technological techniques by milking with robots. Each robot is able to milk up
to 60 head of cattle. They recently put up a barn that holds 1,500 head of
cattle and 24 milking robots. They have both Lely and DeLaval milking robots.
They believe the robots to be extremely beneficial and efficient to their
business because the robots are able to help them in more ways than just increasing
production. The robots are able to measure things such as milk production, milk
content, somatic cell counts, weight of the cow, and helps with heat detection.
Additionally, they have seen their cows produce 2.5 times better than when they
were not housed in barns. Using this system, they are able to milk year round,
rather than when they could not while being pasture based. Each cow wears a
pedometer around her neck to track how many times she has been to the robot. If
the cow has been to the robot an adequate number of times to be milked in a
day, the robot will be able to look this up and send her away to prevent over
milking. The robot attaches the milking machine to the cow using lasers. If
there is an issue attaching the milkers, the robot will try seven times and
then send the cow on her way. It takes around 6.5 minutes for milk prep and for
the cow to be milked.

The Van Leeuwens
grow their own feed for their animals. They feed their animal’s maize (corn),
lucerne (alfalfa), soy, grass, and more. Additionally, they have a very
efficient waste management system that includes scraping lanes, transporting
the waste to lagoons, and using the waste as fertilizer in fields. The Van
Leeuwens run a very efficient enterprise and are not afraid to try new
technologies and do whatever possible to keep their cows comfortable. Some
additional techniques they practice include placing rubber mats in each stall
of the barn, as well as having an automatic feed pusher to push excess feed to cows
at certain times of the day.

We
headed towards Ashburton to enjoy our last night in New Zealand. The feel of
the students seems to be quite mutual; it’s a bittersweet feeling of being sad
to leave such a beautiful country where we have learned so much and made
friends and memories that will last a lifetime. However, we are all very
excited to share with our friends and family at home what we learned, and how
this trip will help us in our future endeavors. Thank you for keeping up with
our trip, and we can’t wait to see you all soon!
