Grass Fed Beef
Grass Fed Beef
By: Maxwell Salinger
In my opinion one of the preeminent
benefits of utilizing a hydroponic fodder feed system is the ability
to more closely re-create our animal’s natural diets. This is
especially true when considering a ruminant animal such as a cow. A
cow’s digestive system has specially evolved to efficiently digest
and convert grasses into a food source; a feat that those of us with
only one stomach cannot accomplish. Traditionally all beef was grass
fed, but with a skyrocketing population a need to speed up production
time became evident; this is where grain-feeding came into play.
Although grain feeding is a much more efficient way to take our baby
calves to their 1200 pound finish weight, there is much to be said
about an increase in the quality of life of our animals when fed a
higher quality food source. This is where hydroponic fodder comes
into play. Although our animals are still consuming a grain based
product, the increased digestibility rate more closely imitates their
natural diet. This natural diet aids in our animals ability to put on
weight in a more healthy and a less physically taxing manner.
If we simply take a look at the
function of a seed from a plants perspective we can gain a little bit
of insight on how it may react with the digestive system of an animal
built to eat grass. Large starch and sugar compounds are deposited
within the seed to prolong the time in which the seed can be
preserved before germination. These compounds are later broken down
and utilized by the germinating plant over the course of several
weeks to ensure the plants survival. This storage mechanism that the
plant depends on to distribute its genetics is actually an obstacle
for our animals to overcome. Instead of immediately fermenting and
digesting organic grass compounds, our ruminant animals have to spend
more energy breaking down the seed’s coat and storage compounds
into a usable form. By sprouting a high quality seed and feeding it
directly after germination we are able to give our animals a fodder
that is in its prime nutritional state.
The premise of grass-fed beef can also
lend to adding value to your animal’s meat and other products. Not
only does a grass-fed certification increase the value of your meat
but it has also been shown to drastically change its composition.
Grass-fed beef has been shown to be leaner, contain more
omega-3-fatty acids and also be higher in many other vitamins that
are important to the human digestive system. Another important
benefit that can be achieved utilizing a hydroponic fodder feeding
system is a higher consistency of feed. One of the major obstacles
that face many grass-fed beef producers is the variability of plant
species within their pasture as well as seasonal fluctuation. By
making a large portion of our cattle’s diet hydroponic fodder, we
can be assured of the quality and quantity of grass that is being
consumed. This consistency can lead to a better tasting end product,
which is one of our major goals. This premise is not limited to
cattle; consistency in feed can also increase the quality of meat and
other by-products of animals such as swine and poultry. Hydroponic
Fodder production is a great way to drastically improve both the
quality of your animal products as well as their quality of life!

Selecting a Growing Structure for Fodder Production
Selecting a Growing
Structure for Fodder Production
By Maxwell Salinger
One of the common
questions often heard at CropKing is the optimal environment for
hydroponic fodder production. To begin to address this topic, one of
the first catch phrases that come to mind is “controlled
germination.” This term fits well with hydroponic fodder production
because we are only concerned with the first seven to fourteen days
of growth. These plants are relying very little on the sun to provide
the energy they need to develop, and more on their “food” stores
within the seed. This “food” or endosperm inside of the seed is
most often in the form of starch. Starch can be
converted to a more
easily digested form for our livestock to consume through the process
of germination. These facts alone can certainly influence the way we
approach our environmental control.
Like any other crop, the grain seeds
we use in a hydroponic fodder system germinate best in high humidity
environments. In vegetable crops we often use a humidity dome or a
propagation greenhouse for the first couple of days before emergence
to keep our relative humidity at 90% or above. This is where our
fodder starts to stray from normal germination conditions. Although
having humidity levels close to this 90% range may speed up
germination, it also speeds up the growth of many molds that can be
extremely detrimental to production as well as animal health. It is
for this reason we look for a humidity range that encourages
germination to a satisfactory rate but does not aid in the
proliferation of these molds. Having precise control of these
humidity levels is thus of paramount importance.
CropKing's research fodder building |
Having solid control of this humidity
can be more challenging task in some buildings more than others. Here
at CropKing I am fortunate to have a 30’x40’ steel structure that
is heavily insulated with a spray foam material with a high R-Value.
This means that my heat and humidity are well conserved and it is
generally not difficult to keep my relative humidity above the
minimum of 60%. It is rare for the relative humidity to drop to a
level unacceptable for germination when at least one of my fodder
units is up and running. Dehumidification though can definitely
become a necessity. There are many equipment options when looking
into dehumidification such as “heat pumps” to the more cost
effective “at-home” dehumidifier made for keeping your basement
less muggy. Heaters can also go a long way to reducing ambient
humidity, but regardless of how you do it; the humidity must be kept
below 80%.
If these facts are kept in mind while
deciding where to put your fodder rack some basic questions arise;
Such as, how much will it cost me to heat/ cool this structure and
what will my dehumidification needs be? When answering these
questions it becomes apparent that it is much more cost effective to
run this type of system in an enclosed and heavily insulated
structure such as my steel building. It seems that it is becoming
more common for people to start growing in
structures such as
greenhouses or poly-huts. The main benefit to growing anything in a
greenhouse structure is the accumulation of “free” sun energy,
which as stated before is not the main concern CropKing's research greenhouse |
facility.
The results were fairly surprising,
the average wet weight and overall height of both sets were almost
identical in both replications. Where I saw the biggest differences
was in the actual grass morphology. The greenhouse grown set
allocated more energy toward the production of roots than shoots,
opposite from that of the fodder building group. These greenhouse
shoots were shorter but the blades were wider and more expanded,
implying that they were actively photosynthesizing at a higher rate
than the closed blades of the fodder building’s shoots. These
results led to the question of protein and fat allocation; “Is it
better nutritionally to have more shoots or roots?”
After getting
samples of both groups sent to Clemson University to be analyzed it
became apparent that much more of the protein and fat within the
plant is stored at the shoots of the fodder than the roots. Of these
shoot samples within this study, on a 100% dry-matter basis it was
also shown that the fodder grown in the enclosed structure had a
higher protein content of 21.9% verse the 17.6% of the greenhouse.
Similar results could also be seen in the comparison of the two sets
of root samples.
While comparing these two growing
environment systems it seems as though in reference to production and
economics it is more advantageous to grow hydroponic fodder sprouts
in an enclosed and more controlled environment. This is not to say
that greenhouse production is out of the question, especially if
hydroponic fodder is the sole crop being grown. Like any protected
agriculture crop, the benefits of hydroponic fodder must be weighed
against the cost of the operation of the equipment as well as the
cost of environmental control.

Maxwell's Fodder Intro
Maxwell originally wrote this article as a feature in Maximum Yield magazine to introduce the concept of hydroponically sprouting cereal
grains for animal fodder. We thought that this would be a great first
blog entry and hope you enjoy!
With hay and grain costs on the rise and continuing
drought immanent, many farmers and ranchers are looking to developing
technology to assure the survival of their businesses. Although slightly counterintuitive,
hydroponic food production has proven to be a great way to reduce overall water
usage and still harvest a wonderful crop. CropKing’s hydroponic fodder system
has been steadily gaining more interest as a feasible method for farmers to
grow their own feed in order to greatly reduce their overall feed costs.
CropKing is a family owned company based in Lodi, Ohio
that has specialized in hydroponic greenhouse production for almost thirty
years and pride themselves on being on the forefront of hydroponic technology.
Although hydroponic fodder doesn’t necessarily need to be grown in a greenhouse
the growing concepts remain the same. This hydroponic fodder system utilizes a
NFT style channel very similar to CropKing’s lettuce systems, but much wider.
In this type of system a small film of water is dripped into one end of the
channel and moved over the plants roots via the slope of the system. For fodder
production, barley seed is spread along each channel without the use of any
sort of growing media and after seven to eight days these seeds emerge as
barley spouts weighing nearly seven
times their dry counterparts!
This process starts with the soaking of a high quality
and contaminate free barley seed for eight to twelve hours. By utilizing a clean seed the risks of future
mold infestations are reduced. After the first couple of days roots and shoots
have started to emerge from the seeds and by day four the barley leaf blades
start to expand. At this point the grass begins to use its ambient light to
start a little photosynthesis and really start to get going. The light levels
required by barley at this stage are no nearly as high as many other hydroponic
crops, making this system easily accessible for a range of growers. A pump recirclates
the water throughout the system on a predetermined schedule, dependent on the
crop and the growing environment. At harvest the barley forms such a dense matt
that it is easily removed from the channel in smaller sections and then rolled
for easier transportation to the feeding location.
Hydroponic fodder sprouts are extremely nutritious and
can be used to feed a huge range of animals from cows, sheep and goats to
chickens and alpacas! Because much of the nutrition within the sprouts is so readily
available it is often recommended that it be paired with a roughage type feed
in order to assure a healthy animal gut. That being said, the quality of the
roughage can be greatly decreased by virtue of the hydroponic fodder’s
richness. The ability of a farmer to produce such a high quality feed while
saving water and reducing the land requirements can go a long way to
“drought-proofing” an operation as well as means to increase animal stocking density.
CropKing is currently conducting research on the nutritional aspects of
hydroponic fodder as well as engineering new ways to maximize the productivity
of their systems.
