METHOD FOR PROMOTING THE PRODUCTIVITY OF ANIMALS AND PLANTS
Detailed Description of the Invention
The present invention relates to a method for pro-
moting the productivity of animals and plants, characterized
by irradiating animals and plants with an alternating magnetic
field which is generated by charging a pulse current having a
waveform similar to that of diphasic action potential to a
magnetic coil.
In the course of studying the influences of a mag-
netic field on the activation of viable cells, the presentinventor found that an alternating magnetic field, generated
by charging a current having a waveform similar to that of di-
phasic action potential to a magnetic coil, is remarkably
effective in activating the growth of viable cells when com-
pared with commercial ac current. This may be explained by
the fact that a small change of magnetic flux d~ during a
short period of time dt, i e. d~/dt, is very higher when a
magnetic field, generated by charging a current having a wave-
form similar to that of diphasic action potential, passes
through viable cells, i.e. 100-folds or higher in comparison
with the case of using sine wave.
It is suggested that a sudden change of magnetic
flux density inevitably couples with the increment of electro-
motive force to cause great electrochemical influences on
viable cells. Also is suggested that such sudden change
effects spin movements of various atoms, e.g. hydrogen atom,
in the viable cells to amplify the influences.

On studying further the activating effect, the
present inventor found that the productivity of animal and
plants, such as domestic animals, domestic plants and cell
cultures, is extremely promoted by irradiating a magnetic
field generated with a pulse current having a waveform similar
to that of diphasic action potential. Thus, the present
inventor accomplished the present invention.
The pulse currents having a waveorm similar to that
of diphasic action potential and usable in the present inven-
tion are those which have a common waveform similar to the one
generated in a stimulated nerve. Figures l and 2 exe~plify
such pulse current.
In Figures l and 2, the pulse width A generally
falls in the range of l/500-l/50 seconds, preferably, l/500-
l/100 seconds, and the pulse interval B generally falls in the
range of l/100-l second, preferably, l/50-l/5 seconds. An
example of a preferred apparatus capable of generating such
pulse current is disclosed in Japan Patent Kokai No. 197,262/
84 (MASAKI, Kazumi). The magnetomotive force o~ such appara-
tus is generally set in the range of 10-100,000 ampere turns.
The terms "animals" and "plants", used in the pre-
sent invention, shall mean varieties of animals, plants, their
tissues or cells which are fed, bred;or cultivated in agricul-
ture, forestry, fisheries, or pharmaceutical industry: for
example, animals such as mammalians, fowls, fishes, shell-
fishes, and insects; and plants such as monocotyledonous
plants, dicotyledonous plants, seaweeds, basidion-mycetous

plants and microorganisms.
The wording of "promoting the productivity" used in
the present invention means the acceleration of growth, deve-
lopment and proliferation of animals and plants, and shorten-
ing of the time required for feeding, breeding or cultivating
them, leading to the improvement in the yields and/or quali-
ties of their products, e.g. animal products such as meat,
milk, egg, fur, cocoon, and pearl, plant products such as
plant stem, flower, fruit, mycelium, antibiotic, enzyme and
biologically-active substance.
In the course of irradiating the alternating mag-
netic field to promote the productivity of animals and plants,
other suitable treatments, e.g. administration of hormone or
vitamin, or control of temperature or intensity of radiation,
may be combined.
The following Examples further illustrate the
present invention.
ExamPle 1
Newborn pigs in litters were divided into two
groups.
Every morning and evening one group of the newborn
pigs was placed into a stable, 1.8 m x 1.8 m in area, equipped
around with an apparatus generating an alternating pulsatile
magnetic field, magnetomotive force of 10,000 ampere turns,
pulse width of 1/400 seconds, pulse interval of 1/30 seconds,
and irradiated twice with the magnetic field for 10 minutes
every day. In other hours without irradiation, the both
rn/
~Z5~3~15
groups of pigs were fed by mother pig. the average period
required to double the weight of newborn pigs was 10 days in
the group treated according to the invention, while the un-
irradiated control required 1~ days.
Example 2
Chickens for broiler, about 1.0 kg each, were fed
with a commercial assorted feed in conventional manner. Two
groups, five chickens each, were placed into different hen-
houses, 1 m x 1.5 m in area. The henhouse for one group was
equipped with an apparatus for generating an alternating pul-
satile magnetic field, magnetomotive force of 1,000 ampere
turns, pulse width of 1/200 seconds, pulse interval of 1/10
seconds, and the group was fed for one week while irradiating
the magnetic field for 30 minutes at intervals of six hours.
The average increase in weight per 1 kg of feed used during
this feeding was 0.41 kg in the group treated according to the
present invention, whereas that in the unirradiated control
was 0.35 kg.
Example 3
A one month-postpartum milk cow was milked while
irradiating an alternating magnetic line pulse by use of a
teat cup equipped with an apparatus for generating an alter-
nating pulsatile magnetic field, magnetomotive force of 5,000
ampere turns, pulse width of 1/50 seconds, pulse interval of
1/5 seconds. This improved the amount of milking by about
25%.

were inserted with middle size nuclides, and suspended in sea
water from a culturing raft in usual way.
An apparatus generating an alternating pulsatile
magnetic field, magnetomotive force of 100,000 ampere turns,
pulse width of 1/100 seconds, pulse interval of 1/10 seconds,
was laid around the raft, and the pearl oysters daily received
3Q minutes irradiations of the magnetic field in the morning
and evening for six months.
The pearls so obtained were top quality pearls ex-
cellent in the growth of nacre layer, color, and brilliance.Example 5
A bed soil was placed in two different vessels, 1.0
m x 0.5 rn in area, to prepare seed beds. The seed beds were
then sown with seeds of Japanese radish, Raphanus sativus L.,
sprinkled with water, and kept in the shade, in usual way.
An apparatus generating an alternating pulsatile
magnetic field, magnetomotive force of 1,000 ampere turns,
pulse width of 1/100 seconds, pulse interval of 1/20 seconds,
was placed around one of the seed beds to irradiate it with
the magnetic field for five days. After harvesting young
radish plants from each seed bed, the crop from the seed bed
treated according to the invention was about ~0% higher than
that from the unirradiated control.

magnetic field, magetomotive force of 1,000 ampere turns,
pulse width of 1/100 seconds, pulse interval of 1/20 seconds,
were placed around one of the group about 0.5 m above the
root, and the group received 15 minutes irradiation of the
magnetic field every morning and evening for one yearO
The group of plants treated according to the present
invention was significantly strong in tree vigor, and their
fruits were superior in color and taste to those of the unir-
radiated control. Also, the crop was augmented by about 2.0-
folds on an average.
Example 7
Seed of "ENO~I-TAKE", Flammulina velutipes, a type
of mushroom, which had been subjected to 20C seed culture
using a liquid culture medium containing 2 w/v % malto extract
was inoculated on two aliquots of a solid culture medium, con-
sisting of 4 parts by weight of sawdust of a chin~uapin, Cas-
tanopsis cuspidata var. Sieboldii, 1.5 parts by weight of rice
bran and 7.5 parts by weight of water, and cultivated at 18-
20C for 40 days, in conventional manner. During the cultiva-
tion, one of the solid cultures was placed within about 1 mfrom an apparatus generating an alternating pulsatile magnetic
field, magnetomotive force of 1,000 ampere turns, pulse width
of 1/200 seconds, pulse interval of 1/10 seconds, and irrad-
iated every six hours with the magnetic field for 15 minutes.
The culture treated according to the present inven-
tion was superior in the growth of mycelia to the unirradiated
control, and the average yield of mycelia was about 3.3-fold

higher than that of the control.
Example 8
Each of 15 liter liquid medium aliquots, consisting
of 2 w/v % soluble starch, 1 w/v ~ NH4NO3, 0.1 w/v ~ K2HPO4,
0.05 w/v % MgSO4.7H2O, 0.5 w/v ~ corn steep liquor, 1 w/v %
CaCo3 and ~ater, was placed in a jar fermenter, and sterilized
by heating at 120C for 20 minutes. After cooling each liquid
medium to 50C, a seed culture of _acillus stearothermophilu
FERM-P No. 2222 was inoculated thereto in an amount of 1 v/v
%. An apparatus generating an alternating pulsatile magnetic
field, magnetomotive force of l,OOQ ampere turns, pulse width
of 1/400 seconds, pulse interval of 1/10 seconds, was equipped
on the inside wall of one of the jar fermenters which was then
incubated at 50C for 48 hours under aeration-agitation condi-
tions while irradiating the magnetic field. Another jar fer-
menter, used as the control, was incubated similarly as above
but without irradiation.
The level of cyclodextrin glucanotransferase in the
jar fermenter treated according to the present invention was
about 45~ higher than that in the unirradiated control.
