For both commercial farms and backyard
hobbyists, feed mills are a necessity of life. Feed mills are able to
consistently produce quality feed for our animals with the nutrition
they need. But what actually occurs in a feed mill?
L A Hearne has been our source of feed for over
30 years and we were recently invited for a tour of their mill
located in King City, California. Their manager, Mike Hearne, was
very enthusiastic about showing us around, starting with the outside
of the mill.

Every Thursday a train car rolls in with
a delivery of corn which is emptied into a vent under the rails. The
corn is then transferred
to their grain storage
building which contains different kinds of grain including corn,
oats, barley, and rice.

The mill caters to hundreds of customers
including feed stores and other commercial growers,
all with different feed needs for different animals ranging from our
ducks, to horses, to rabbits! The feed is usually sold in bulk to
commercial customers and put in 20, 50 and 80 pound bags for their
feed store customers. All our feed is delivered in bulk - meaning it
is augered directly from the feed truck into our feed tanks, and each truck has 24 tons of feed.

Determining what grain and additives to use and
in what quantities in a feed ration is a fairly complex process with
several factors needed to be taken into consideration. We will cover
this in another post in the future.
Feed is made in batches of two tons. Prior to
being ground and mixed, all the grains are sent through a sifter to
remove any broken pieces of grain and any contaminates. The sifted
grains are then sent into a grinder in preparation to be turned into
pellets. Different vitamins and minerals are placed in bags
beforehand, ready to be mixed into the ground grains. We were lucky
to be visiting that day as they were mixing our feed!

The complete, ground ration is called a mash.
For some chicken and swine feed, this is the product’s final form.
For others, the mash is flash steamed to increase the
temperature and then, pu
shed through a pellet
die, kind of like frosting through a piping tip. As the ropes of feed
emerges from the die a knife cuts it into pellets of the desired
length. By flash steaming the feed, all of the bacteria is destroyed,
leaving a clean food source.

The pellets are then sent through a dryer to
remove any leftover moisture, preventing mold. For more information
on mash, pellets, and crumble feed, take a look at our post on the different forms of feed.
The final product is then packaged and shipped
to customers and feed stores.

Thank you LA Hearne for a tour of your mill! Keep up the good work and see you next week!
