English Abstract

A livestock feeding regimen which increases the amount of beneficial omega
fatty acids
expressed in milk from lactating animals, i.e. dairy cattle and goats. A
further embodiment of the
invention is the meat from livestock animals fed under the same or similar
feeding regimes and
containing the same beneficial omega fatty acids. The invention includes a
comprehensive system of
combining specific fish meal/oil dietary supplements, sodium bentonite (clay)
and particular herd
management techniques for achieving enhanced levels of beneficial omega fatty
acids in milk and
meat. Dairy cattle, goats and other lactating animals are fed a special
supplement containing cold
marine fish meal and/or oil known to contain beneficial omega fatty acids and
a high fibre diet plus
sodium bentonite to prevent microbial degradation of the beneficial omega
fatty acids in the rumen.
The beneficial omega fatty acids enhanced liquid milk produced by this
invention, and the further
processed dairy products, are covered by this invention. Meat from livestock
fed under this invention
are also covered by this invention. Algae are also an excellent source of
beneficial fatty acids as an
alternative to fish meals/oil.

TITLE
Method for producing milk and meat products containing beneficial omega fatty
acids and the milk
and meat products produced from such method.
DESCRIPTION
INTRODUCTION
There are several forms of compounds known as omega fatty acids that have been
shown to
be highly beneficial for human health. The beneficial omega fatty acids are
found in abundance in
cold marine fish, and oils from such fish. It has also been determined that
the direct feeding of algae
to livestock will produce the same result. Algae are the main source of
beneficial fatty acids by fish.
The beneficial omega fatty acids include docasahexaenioc acid (DHA), alpha
linolenic acid
(LNA) and eicosapentenoic acid (EPA). These are the three main omega fatty
acids implicated in
healthy effects. The names are derived from the fact the first of several
double bonds occurs three
carbon atoms away from the terminal end of the carbon chain. LNA is an 18
carbon chain fatty acid
with three double bonds and is an important plant based source of omega 3
fatty acids. LNA can
only be converted to DHA metabolically to a very limited extent.
DHA has been shown to be very important in brain and eye development. High
levels of
DHA are required for optimal mental functioning and visual performance. DHA is
an extremely
important dietary nutrient for infants and children.

PURNUTRA INC. - OMEGA 3 MILK PATENT
The benefits from specific omega fatty acids are well established in the
scientific and
medical research literature. In the United States patent by Wright et al., a
series of studies
relating to omega 3 fatty acids and EPA are cited.
A number of patents have been issued for the purpose of enhancing specific
beneficial
omega fatty acids in foods normally deficient in these compounds. This is
usually accomplished
by feeding cold marine fish meal and/or oil to the target animals. Wright et
al in United States
patent 5,932,257 disclose such a use. The source of DHA is cold marine fish
meal and oil. In the
Wright patent feathermeal is used to prevent microbial breakdown of the DHA in
the rumen of the
dairy animal. Feathermeal can create a feed with low palatability and
livestock will have difficulty
eating sufficient feed for good nutrition or production.
Omega 3 eggs are common in stores in Canada. These omega 3 eggs are primarily
produced by feeding laying hens a diet enhanced with flaxseed.. Gold Circle
farm eggs
containing the omega 3 DHA/EPA compounds are widely sold in stores in the
United States.
SUMMARY OF THE INVENTION
The instant invention provides a means of producing milk from lactating
animals, i.e. dairy
cows and goats, enhanced with beneficial omega fatty acids by adopting a
holistic approach to
feeding and managing the lactating animal. The use of the described feeding
and management
regimen eliminates the need for feathermeal or other unpalatable substances as
a rumen by-pass
agent. The feeding system provides health benefits to the target lactating
animals and produces
milk with the required levels of beneficial omega fatty acids to promote human
health.
The farmers conducting the research supporting this invention have noticed
that cows on
the dietary supplement and feeding regime appear healthier than cows on
standard diets. The

production of milk has either remained the same or the farmer has achieved
higher levels of
production with lower butterfat levels.
The uniqueness of the instant invention is the combination of known dietary
supplements
containing cold marine fish meal and/or oil or algae, combined with clay
(sodium bentonite) and
the management regimen of feeding the dietary supplement to the target animals
with high fiber
diets, i.e., corn silage, which results in elevated levels of beneficial omega
fatty acids in the milk.
Although a wide range of clay materials can be used, the clay must be of feed
grade for the target
animal. A preferred source of clay is sodium bentonite.
Milk products made from milk produced by this invention will have significant
levels of
beneficial omega fatty acids. Algae containing the appropriate amounts of
beneficial omega fatty
acids may be substituted for part of the cold marine fish meal or oil in the
feed formula.
An example of the dietary supplement is as follows:
Menhadden meal* 240 Kg.


Hernng meal 240


Barley 200


Soy hulls 212


Sodium Bentonite 40

The milk test results for three (3 ) specific cows, from a research herd fed
in accordance
with this invention, are as follows:

In addition to fresh table milk, dairy products, i.e. cheese, yogurt, ice
cream curds, sour
cream and cottage cheese, made from the milk produced under this invention
will also have
nutritionally enhanced levels of beneficial omega fatty acids.
Cheese has been manufactured from milk from dairy cows fed in accordance with
this
invention. The beneficial omega fatty acid conjugated linoleic acid (CLA) was
found in one
sample to be 0. S8% of total fat.
