The Total Mixed Ration (T.M.R.) System
The R.M.H. Mixer feeder is part of a balanced feeding
system or T.M.R. (Total Mixed Ration). By balanced feeding, we mean feeding
the animal a feed ration with the correct amount of energy, protein and
minerals. By feeding a completely nutritious ration, maximum production
can be achieved. The ration is based on feeding silage, hay, grain and other
materials. By putting the materials in a R.M.H. Mixer feeder, a highly uniform
mix is achieved, thus enabling you to use waste materials of high energy
and protein value such as potato waste, cotton seeds and others, some of
which would be unpalatable on their own but being mixed they are readily
consumed by the animals. R.M.H. mixer feeders are able to mix any feed stuff
available (usually without any pre-processing required) such as molasses,
brewers grain, cotton seeds and hulls, hay rectangular (small or large)
or round bales, silage and fine materials, additives and liquids etc, all
mixed to a 98% uniformity. This mixing uniformity is not taken lightly and
to prove our statement of 98% we have had our machines tested by the fully
independent D.L.G. Laboratory in Germany. They mixed over 2500 tonnes of
materials and analysed each load for uniformity etc. Our Mixers passed their
stringent tests and now proudly display the D.L.G. logo.
| The Basis of T.M.R. System
The first complete feed via feeder-mixer was introduced
into the U.S.A., South Africa and Israel in the late 1960's, and today
after realising their true economical potential, they have become the
most popular feeding system in the world to both dairy and beef farms.
The complete feeding system for dairy cattle is based on feeding cows
a ration, balancing the correct amount of energy, protein, fibre, and
minerals, in order to produce maximum yields of milk in the most economical
way. A typical balanced ration would include some of the following ingredients:
silage, hay, grains and by-products from the food industry. These ingredients
are weighed and mixed in the R.M.H. mixer feeder and fed to the cow as
a complete diet or perhaps a partial diet. Every cow then gets a complete
ration in every mouthful which prevents "boss" cows getting the best feed
and also stops cows "sorting" the best ingredient first and perhaps leaving
the lesser materials, because mixing the feed accurately means the cow
doesn't differentiate between the individual ingredients in the ration.
Also we have the ability to put products into the ration that the cow
would not eat at all but by disguising them in amongst other more palatable
ingredients the cows eat them readily. A lot of meals and waste products
fall into this category.
The nutritional value of pasture varies tremendously throughout the year,
starting from early spring pasture that is soft and watery and has some
nutritional deficiencies, later in the year grasses are leached and bleached
increasing fibre and decreasing energy, protein and minerals.
A cow would have to consume 17 kg DM pasture in order to satisfy her maintenance
needs and milk production, while the quality of the pasture is at its
peak. Where as the same cow would have to consume 27 kg DM of low value
pasture to achieve the same maintenance and milk production. However a
500 kg cow can only consume a maximum of approximately 17 kg DM, so you
can see that when she grazes low value pasture she cannot obtain enough
nutritional value to maintain her maintenance needs in milk production.
(see figure 1)
By harvesting any crop at its peak nutritional value, preserving
it and feeding it to the cow on a regular basis, milk production can be
Other factors to be taken into consideration in pasture feeding, is a
reduction of crop yields in the paddock due to compaction of the soil,
trampling an manure fouling, approximately 60% - 70% only is utilised.
It is a known fact that when cows have to walk to far paddocks. Their
milk output suffers by 0.62 litres for every kilometre walked. So farmers
are now growing crops on these far paddocks which are harvested at peak
nutritional value and fed back to the cows at later date.
Feeding lactating cows differs from feeding other classes of farm animals.
There is a limited time between calving in which to get whatever milk
the cow will produce. Milk production reaches a peak 2 to 6 weeks after
a cow freshens, then declines during the remaining time of the lactation.
If feeding is limited, the peak production will not be reached and the
rate of decline is more rapid than normal so production is lowered. However
by feeding a supplementary T.M.R. from just before calving right through
the lactation, production is increased. Dividing cows into feeding groups
has led to changes in the economics of dairy production. The feeding is
based on production groups, rather than the needs of the entire herd.
By feeding cheaper feeds to lower producing groups, considerable amounts
of money can be saved.
Feed, more than any other factor, determines the productivity and profitability
of dairying. Within a herd of approximately 25% of the difference of milk
production between cows is due to heredity (breeding), the remaining 75%
is determined by environmental factors, with feed making up the largest
portion. Feed accounts for an average 55% of the cost of milk production.
Therefore, a good feeding program is necessary for profitable milk production.
It costs more to feed high producing cows, but it pays for the following
reasons: Feed overhead and maintenance costs are practically the same,
regardless of the level of production. (see figure 2)

used for maintenance decreases as production increases. (based on data from

What the complete feeding system requires:
What the complete system offers you:
- An R.M.H.
Mixer feeder suited to your application.
- A feed centre where all the feeds, whether bought in or grown on farm are stored
correctly in close proximity for ease of loading into the mixer feeder.
- A feeding area for the cows to be able to feed on, usually some form of concrete
- Nutritional advice is required for you to be able to balance your feeding program,
we will assist you in this area drawing on experience from Israeli thinking and Australian experience. We believe in keeping the ration
simple but effective.
- Increase in milk production by feeding a balanced cow ration and having no feed shortage.
- Ability to use cheaper feeds in the ration.
- Growing on farm crops harvested at peak nutritional value to feed with other ingredients later.
- Buying feeds at harvest time to ensure the lowest price but highest quality.
- Better herd health.
- Better conception rates.
