Consider cow welfare when designing housing
Dairy farmers should consider the health and welfare of their cows when building housing for their stock, says New
Zealand Veterinary Association president Richard Wild.
A recent paper on the welfare of cows kept in grazing and housed systems, concluded that New Zealand dairy cows are
generally better off living outside grazing pasture than being housed inside in barns.
"With New Zealand dairy farming expanding into new geographic areas, it is timely to evaluate the matter of housing,"
says Dr Wild. "Milking cows are valuable animals and deserve the best conditions we can provide."
The review paper, written by veterinarian Richard Laven and dairy scientist Colin Holmes, was published recently in the
New Zealand Veterinary Journal. It lays out the advantages and disadvantages of housing for dairy cattle welfare in the
New Zealand environment. One of the obvious benefits is protection from inclement weather.
"While housing gives the benefit of protecting cows from adverse weather – both hot and cold – results from overseas
show it can detrimentally affect welfare by increasing the risk of mastitis and lameness," says Dr Wild.
"The types of lameness and mastitis are also different in housed cows and require different strategies for management."
He says housing cows is an expensive option, so getting the design right is critical as health and welfare issues need
to be taken into consideration. Farmers also need to consider the cost incurred, not only in buildings, but also in
increased labour requirements.
"Veterinarians can assist farmers who are designing stock housing, by helping them to anticipate and eliminate potential
problems as far as possible," says Dr Wild.
"Animal health plans can be tailored to ensure farmers have systems in place to monitor stock and identify the different
health problems that may be encountered in housed animals."
Dr Wild says there is a lot of information available about different dairying systems.
“New Zealand veterinarians and dairy farmers need to work together to ensure that dairying in this country benefits from
reports on international experience.”
