When it comes
to dairy, there is a very common misconception out there. It’s the idea that
unlike meat production, which obviously requires an animal to be killed, other
animal products like cow’s milk can be produced without harm. “The animals get
to live.” “I can enjoy a glass of milk or piece of cheese without any animal
being hurt.”
First, the
facts
Let’s start
with some basic mammalian biology that is often overlooked. For a female mammal
to produce milk, she of course needs to first become pregnant. Impregnation of
dairy cows is commonly carried out using artificial insemination, a procedure
that requires sperm to be collected from a bull and then manually inserted into
a restrained cow, through a process that involves both rectal and vaginal
intrusion.
The pregnancy
lasts about 9 months. If born female, both dairy and beef calves will be raised
to be repeatedly impregnated to produce new calves. If born male, they will be
fattened and slaughtered at a premature age (that is, if the former are not
considered surplus product and culled shortly after birth). The main conceptual
difference between dairy and beef production systems concerns the milk produced
by the female mother cows (“dams”), and the implications of its production and
collection on the animals and their management.
Long-term
genetic selection for high milk yield in dairy cows has been recognised as a
major factor causing poor welfare because it is associated with health
problems, such as lameness, mastitis, reproductive disorders and metabolic
disorders.
Common housing
and husbandry procedures for dairy cattle increase the welfare risks further.
For example, while beef calves are commonly allowed to suckle milk from their
mothers, dairy calves are separated from their mothers shortly after birth so
that milk can be collected daily, several times a day, for human consumption.
Understandably, separating a mammal from its offspring at such an early age has
clear welfare implications for both sides of the dyad, especially when
considering the conditions and management of the animals following the
separation. For instance, upon separation, dairy calves are often kept in
social isolation for several weeks (i.e. limited or no physical contact with
their dam and other calves), a management practice that has been repeatedly
shown to inflict behavioural and developmental harm on the animals.
The study
In comparing
the welfare of animals in dairy and beef herds, when raised using the most
common production methods. Our hypothesis was that the welfare of dairy cattle
is lower than that of beef cattle due to the higher level of (negative) human
intervention in their lives.
To explore this
hypothesis, recruited 70 leading bovine welfare experts from Europe (35), North
America (17), South America (8), Australia (5) and other regions of the world
(5). The experts, with a median experience of at least 15 years, were asked to
rate the likelihood of beef and dairy cattle experiencing a compromise to their
basic health and functioning, affective states, and ability to engage in
natural behaviours when raised in the most common production systems. The
assessment provided by the bovine experts clearly showed that dairy cows are
more likely to experience worse welfare than their counterparts in beef herds.
The study
investigated twelve areas of potential welfare concern:
Inadequate diet
Inadequate
water supply
Thermal
discomfort
Resting
discomfort
Injuries
Disease
Inability to
move freely
Pain
Limited ability
to express social behavior
Limited ability
to express other normal behaviors
Negative
affective states
Limited ability
to experience positive affective states
The higher
welfare risk in the dairy sector was not limited to dairy cows—defined from
first calving onwards—but also, to their calves. Experts rated the welfare risk
of calves originating from dairy herds to be higher than that of calves
originating from beef herds, regardless of the production goal, be it for red
meat, veal, or to replace the dam. These findings contradict a very long and
widely held belief in our society about the impact of dairy production on the
welfare of cattle.
What about
organic/free-range products?
Study focused
on the most common production systems, but similar contrasts between dairy and
beef cattle are expected even if the best-known “welfare” conditions are
provided to the animals. This is because animals in dairy herds are used for
more than their meat, and this has implications for the experiences of the cows
and their calves.
Keeping dairy
cows together with their calves (i.e. dam-calf dairy operations), with free
access to pasture or simply providing them with pain relievers when needed may
certainly improve their current welfare state, at least to some extent.
Nevertheless, raising beef cattle in similar improved conditions (i.e. solely
for their meat), is expected to compromise their welfare to an even lesser
degree.
Making a
difference for animals
With a projected
20% increase in global milk production by 2029, the highest among all livestock
commodities, the toll of milk production on animals in the dairy industry may
require a thorough revision of our current societal, political and moral
decisions.
Decisions make
day to day as consumers can make a difference. The next time you walk down an
aisle of cooled food products at your local supermarket, or check the food menu
of a local coffee shop, consider these two points:
1. Dairy
production = meat + milk production.
2. Animals
raised for dairy production suffer worse welfare conditions than those raised
solely for their meat, regardless of whether they are raised for their meat or
milk.
As a consumer
understanding the facts above, you can choose to support one production system,
both, or neither of the two. I hope that our study will raise awareness to the
link between dairy and meat production, and finally put to rest the myth that
dairy production causes less harm to animals than beef production.
