To
keep producing milk for human consumption, a dairy cow must
produce a calf each year.
- Calves
are taken from their mothers' within12-24 hours of birth.
- The
separation of the calves from their mothers breaks a strong
maternal bond, and both cows and calves suffer.
- Unwanted
bobby calves are killed and some bull calves are raised for
veal. Heifer calves may be reared as herd replacements.
- The
natural life span of a cow is about 20 years, but few dairy
cows are older than seven when slaughtered.
- The
modern dairy cow can yield around 35-50 litres of milk per
day - about 10 times more milk than her calf would need (if
she were permitted to keep it).
- Selective
breeding and more recently genetic manipulation have resulted
in cows being forced to produce milk beyond natural capacity
and suffering is a result.
- Dairy
cows are highly susceptible to many diseases such as mastitis,
and incidence of infection and injury.
DAIRYING IS A BOOMING "INDUSTRY" - AT THE EXPENSE
OF COWS
Bos
taurus was the ancestor of today's Western dairy cow. She had
small udders situated on the highest point of her belly and
produced enough milk for her calf. The modern scientifically
bred and fed dairy cow can produce around 35-50 litres of milk
per day. Generations of selective breeding and now genetic engineering,
have distorted her body structure to suit the purpose of humans.
Her udder is now large and pendulous and her teats hang low.
Manipulating the cow as a milk and meat machine: Artificial
insemination (AI) is taking the place of natural mating and
even AI is being replaced by embryonic transfer. Part of this
procedure may be uncomfortable or painful for the cow. The UK
Veterinary Surgery (Epidural Anesthesia) Order 1992 acknowledges
that epidurals need to be given, although this does not have
to be done by a veterinary surgeon.
Embryos from 'superior' cows can be implanted into receiver
cows of 'poorer' quality. However, if the resulting calf is
too big for the receiver cow, she may have trouble giving birth.
Embryonic transfer is not common in Australia, except in some
'elite' herds, but son may be now that Australian scientists
from Genetics Australia Ltd and Monash and Melbourne Universities
have developed an automatic system for mass-cloning the embryos
of elite cattle. It is expected to lead to a huge rise in productivity
in the dairy and beef industries. With this system, cows not
needed to produce dairy herd replacements could become receptacles
for producing cloned 'quality' beef calves.
Frustrated Maternal Instincts: To keep producing milk for human
consumption, a dairy cow must produce a calf each year. A young
female (heifer) has her first calf at two years of age. The
calf is taken away, usually within 12-24hours of birth, and
the mother is milked to capacity. She is ready to conceive again
about three weeks later, and every three weeks after that. She
is put in calf again at her second or third heat, and milking
continues for 10 months after she has given birth. She is rested
for some weeks before the next calf arrives, then the cycle
continues for as long as she can continue to produce enough
milk to be a "profitable unit".
The
cruelest aspect of dairy farming and probably that, which causes
a cow the most stress, is being separated from her calf. She
has strong maternal instincts and will submit herself to considerable
personal discomfort and risk to nourish and protect her calf.
This aspect alone makes dairy farming highly questionable on
animal welfare grounds.
Constant milking wears cows out prematurely: The natural life
span of the cow is around 20 years, yet few cows live beyond
the age of seven and many younger animals go to slaughter. The
average life of a New Zealand cow, for instance, is only four
to five lactations.
Being forced to produce vast quantities of milk day in, day
out, wears a cow out very quickly, causing her milk yield to
decline, rendering her less able to become pregnant and making
her more susceptible to infections such as mastitis and bloat.
The milking machines itself may render the cow more susceptible
to infection. The front teats may be subjected to vacuum pulsing
for up to two minutes after the quarter has been emptied and
while the hind teats are still yielding. This is believed to
be painful for the cow and may also weaken tissue.
Research in Britain has shown that nearly every cow who ends
up at the abattoir has or has had foot damage or some kind.
The major causes are unnatural feed, selective breeding and
inappropriate housing.
Free-range dairy farming: In Australia and New Zealand, dairy
herds are almost exclusively pasture-fed. But cows are nevertheless
treated as mere milk producing machines. High tech milking platforms
process them with speed and indifference. An 80-bail rotary
platform, for instance, can milk 650 cows per hour. Computers
do most of the "managing" on today's dairy farms.
Life for grazing cows is not without its problems, particularly
when herds are large. In New Zealand, where the average herd
size is about 180 but increasing up to 1200, grazing tends to
be in groups of 200-300 and cows may have to walk long distances
for milking - sometimes 6-10 km a day. In a large herd a cow
may feel confused and stressed as she jostles for a position
in the hierarchy. A low ranking cow can end up with nowhere
to feed and lie. A high ranking cow may become stressed as she
works to maintain her position.
Intensively housed dairy cows: In the Northern Hemisphere more
and more cows are being intensively housed and not just during
winter. Some dairy systems do not even need a separate milking
shed. The cows are tethered in stalls and a portable milking
machines does the rounds two or three times a day.
Much cubicle housing in the UK was built 20-30 years ago when
cows were shorter. Bigger cows such as Holsteins often stand
with their feet in dunged passageways, which causes softening
and cracking of the sole, allowing infection to enter.
A cow who is unable to exercise or lie down comfortably (cows
like to lie down for about nine hours a day) is prone to joint
stress and infections which enter through the foot. A cow denied
access to grazing may exhibit stereotypical behaviour such as
tongue rolling.
Diseases and injuries: The milk yield of Australian and New
Zealand dairy hers may be lower than that of European cows (which
are semi- or permanently housed and fed on grain and concentrates),
but silage (processed grass) and starchy, high protein feeds
based on grains, soy beans, fish meals and animal wastes are
unnatural foods for the cow and can result in severe gut and
foot problems.
A common infection in dairy cows is Mastitis, a painful condition
of the teats, caused by bacteria. Other infections and illnesses
to which high yield dairy cows are prone are bloat, ketosis
(a disease of the liver), milk fever, grass staggers (magnesium
deficiency) and enzootic bovine leucosis or EBL (contagious
viral cancer).
Of major concern in the UK in recent years has been a fatal
dementia, bovine spongiform encephalopathy, known as BSE or
"mad cow" disease, which may be transmitted to humans.
It is caused by giving cows feed containing infected offal from
sheep and other cows. It has not occurred in Australia or New
Zealand.
Whether kept at pasture, yarded or housed, cows can suffer from
heat stress. Solar radiation, humidity and air temperatures
above 26 degrees Celsius are all factors, which can cause severe
stress.
Bovine Growth Hormone: Bovine somatotropin (BST) is a genetically
engineered dairy cow hormone which increases milk production.
The necessary frequent injections are painful for the cow. To
make the already overworked cow produce still greater quantities
of milk through stimulation by hormones is to treat her more
and more as a machine, not a sentient animal.
Although BST is not used in Australia (the dairy industry feared
a possible adverse reaction from the milk-drinking public),
it was legalized for use in the USA in February 1994, despite
opposition from some sections of the public and the dairy industry.
In the European Union the Council of Ministers has declared
a moratorium on its use until the year 2000. A poll by Compassion
in World Farming in 1988 found that 83 percent of UK consumers
opposed the use of BST, as do many farmers' organizations.
BST is said to increase the incidence of mastitis, indigestion,
bloat, diarrhoea, leg and foot problems, anaemia and to cause
more incidences of cystic ovaries and uterine disorders and
calving problems. At least one manufacturer put out a printed
warning to this effect.
Some farmers are saying that an increased susceptibility to
infection is related to putting even more stress on the cow
by using BST to increase her milk yield. An increase in infection
creates an even greater need for antibiotic treatments. Higher
levels of bacteria and residues of antibiotics could occur in
milk.
Another argument against BST is the fact that IGF-1 (insulin
growth factor) is increased in treated cows by 360 percent.
Some researchers say this could lead to more incidences of breast
cancer and premature growth stimulation in humans and breast
growth in young children.
Milk and other dairy products - Calcium and osteoporosis: "Although
promoted as good sources of calcium, vital for strong bones
and 'preventatives' against osteoporosis, milk, cheese, yogurt
and ice-cream are not really wholesome sources of calcium. These
dairy products contain significant amounts of saturated fat,
allergy-inciting cow protein and pesticides, as well as a large
load of phosphate, which can neutralize the benefits of calcium."
"Consuming dairy products does not seem to prevent osteoporosis.
The nations with the highest levels of dairy product consumption
are also the nations with the highest rates of osteoporosis.
This effect is probably due to the calcium-robbing effect of
the accompanying concentrated protein load of animal products,
including the protein found in diary products themselves."
"In one study (sponsored by the US Dairy Council) women
consuming three eight-ounce glasses of cow's milk per day still
lost calcium from their bodies and remained in negative calcium
balance even after a year of consuming almost 1500 milligrams
of calcium daily! It is the high protein diet, laden with poultry,
fish and dairy products that steals calcium from the body rather
than insufficient calcium consumed in the diet."

Humans are the only animals who consume milk after weaning and
take it from other animals:
Dairy products have been linked to diseases such as arthritis,
diabetes, ovarian cancer, breast cancer allergies, respiratory
diseases, digestive problems and cataracts.
Dairy products interfere with the body's absorption of iron.
SOY - a healthy substitute for cow's milk: Research in Britain,
the US and Japan has provided strong evidence that women can
lessen the risk of breast cancer by consuming soybean products
such as soy milk and tofu.
Genetically engineered animals, including cows are now being
used as living factories for produce pharmaceuticals for human
use in their milk. A new word "pharming" has been
used to describe the process and it is regarded as a growth
industry. The effect on the general health and welfare of animals
used in this way has yet to be fully investigated.
Calves
have been used in artificial heart experiments. In 1991 in the
US a calf called Holly lived for a record 224 days on an electrical
heart replacement device. As the device was said not to pump
enough blood to allow for the animal's normal growth, early
death was inevitable.
Milk
and milk by-products are used in many foods. Huge amounts of
milk are used in chocolate and other confectionery, biscuits,
bread and cake mixes, and margarine. Whey powder, a milk by-product
is used in processed foods, baby foods and stock feeds.
IN
AUSTRALIA 1 MILLION BOBBY CALVES ARE KILLED EACH YEAR.
Premature
Induction: Often cows are calved over a tight six to eight week
period so that their feed demands coincide with lush spring
pasture. Calves due outside this period are aborted or prematurely
induced to bring their mothers into line for the next season.
From an animal welfare point of view this is an unacceptable
practice. Abortion may cause the afterbirth to be retained after
calving and serious (sometimes fatal) infections to the cow.
Premature calves, which survive induction, are likely to be
much weaker and often have to be destroyed. Some of these immature
calves are transported and sold, causing further suffering.
The handling and transport to abattoirs of any calves less than
one week old can cause them acute stress.
What
happens to the dairy calf that is deprived of care by and bonding
with its mother as well as the very natural food that is birth
facilitated, which is taken from its mother for human consumption?
- most
are killed, having been sold as bobby calves or raised for
veal or beef production.
- calves
reared for replacements in the dairy herd have their lives
"managed" soon after birth.
- the
calf is removed from the mother before it is four days of
age.
- identification
in the form of ear tattoos and branding are applied.
- extra
teats are removed, usually cut off with sharp scissors.
- the
calf is dehorned with either chemicals or a heated iron held
over the horn bud. Older calves are dehorned with a mechanical
de horner to ensure all the growing horn is removed.
Feeding:
- in
the managed calf the development of the rumen (one of the
four components of a cows' stomach) is hastened by feeding
practices adopted.
- for
economic reasons, to prevent disease from milk products and
to ensure a good capacity for future milk production the managed
calf is introduced to dry feeding as soon as possible.
- commercially
prepared milk replacer powders are used and these are boosted
with antibiotics, vitamins and minerals.
- dry
food is given in the form of protein meal, made from meat
meal or other forms such as cotton seed, linseed or soybean.
Diseases:
- common
calf diseases include scours, leptospirosis, worms, tetanus,
black leg, pneumonia, ringworm, mycotic dermatis, ticks and
lice.
- scours
can be caused by lack colostrums (the calves initial feed
from the mother), poor nutrition, lack of hygiene or overfeeding.
- drenching
and vaccination programs are carried out for disease.
Each year cows are lost from the dairy farm either through death
or culling, with an expected loss of up to 20 in a herd of 100
cows. Calves are reared for replacement. Many calves kept for
replacement die before weaning. If the calf survives maternal
deprivation, artificial feeding, early dry food intake, drenching,
dehorning, tagging/branding, teat removal (if necessary), scours,
other diseases and vaccinations, then she will be considered
for mating at 15 months, ready to give birth to her first calf
at 2 years of age. She may be mated naturally, or by using artificial
insemination. After giving birth, she will join the milking
herd to find her place in the social structure and learn the
milking routine. If she proves "inadequate" she will
be culled from the herd (slaughtered), but her calf will already
have been taken from her soon after birth, either to be slaughtered,
raised for beef production or, deprived of its natural inheritance,
to become part of the managed system of milk-production.
The Veal Industry
The dairy industry produces hundreds of thousands of dairy calves;
unwanted males and females in excess of those required for herd
replacement are not usually retained. It is the unwanted calves
that are the basis for the veal industry.
'White'
veal, 'pink' veal, and just 'veal' are descriptions of a meat
product which indicate to those concerned about animal welfare
and those in the meat industry the conditions and husbandry
methods used to raise calves for slaughter.
White
Veal
Of primary concern to the animal welfare movement has been the
cruel 'white' veal industry as it occurs in Europe and Northern
America. White veal is a result of confining dairy in single
crates measuring approximately 1.5 by 0.65 metres. Calves are
kept in crates from only a few days of age to between 10 to
16 weeks of age. The calf is unable to turn around and may almost
fill the crate by the time it reaches slaughter weight. The
calves are fed a low iron milk replacer and have no access to
roughage. In most calves this leads to anaemia. Some sheds are
almost completely dark.
The
Federal Government and State Governments in Australia have expressed
opposition to the 'white' veal system of veal production. Despite
the official positions many in government departments have agreed
that 'white' veal production may be occurring in Australia without
their knowledge.
Traditional
veal in Australia
Traditional 'veal' has come from two sources. Bobby calves are
bull calves or heifer calves not required for herd replacement
in the dairy industry and are killed at only one week of age
or less. Up to 750,000 bull calves alone are said to be sent
for slaughter each year in Victoria. This meat is also referred
to as 'baby veal'. The second traditional source of veal in
Australia is from 'vealers' which are calves, often beef cattle
breeds, which are permitted to run with their mothers until
some six months of age. These calves have access to milk and
grass in the paddock until slaughter.
Pink
Veal
To produce 'pink' veal calves are housed in a semi-intensive
system which denies them access to green grass and the freedom
of the paddock. These (bobby) calves are usually those not required
by the dairy industry and which would normally be sent to the
abattoir to be killed for 'baby' veal. Instead they are placed
in group pens, perhaps four to five in an area 10ft by 8ft (larger
for older calves) and fed milk or milk replacer and pellets.
They have access to roughage and light in usually not restricted.
The calves are often on a floor of sawdust or rice hulls or
similar absorbent material, though the Australian Veterinary
Association Policy suggests a flooring of 'raised wire mesh'
and rejects sawdust due to a lack of hygiene.
These
calves must endure these conditions purely to produce a luxury
product. Consumer tests have shown that 'white', 'pink' and
darker veal are indistinguishable in taste. Lighter meat is
perceived as leaner and younger and therefore preferred by restaurants.
People in government and on the farms only speak of 'meat colour'
and market development when discussing the reasons for the development
of the 'pink veal' system. These living animals are being treated
as little more than a consumer item whose presentation requires
modernizing to create a market demand and to obtain a higher
monitory return for surplus calves from the dairy industry.
