Dairy Cattle Code of Practice - Progress Update

Fourth meeting – March 30 and 31, 2020

The March meeting of the Code Development Committee was adapted to a remote/online format consisting of 3 sessions each focused on the remaining priority welfare issues the Scientific Committee is reporting on (lameness and injuries, end of life management, and exercise and outdoor access).

Trevor DeVries and Elsa Vasseur, speaking on behalf of the Scientific Committee and their Research Writer, presented an overview of the research on each of these topics. This was followed by a Q and A and while most questions related to the research summarized, committee members also posed questions to other committee members. In this way, the group was able to draw out the various types of expertise around the “virtual table”. The last portion of each session consisted of a roundtable with committee members offering preliminary thoughts on the topics presented and possible ways to address them in the updated Code. While this made for a great exchange of insights, it is very much the first of many discussions to be had while committee members continue to digest all the research on these complex topics to be addressed in the updated Code of Practice.

Some examples of the main topics addressed in the research report are outlined below. The next meeting has been scheduled for June (also remote/online). In the meantime, the Scientific Committee’s report will be peer reviewed and sub-sets of the Code Committee will continue to draft selected sections of the Code for later review by the entire Code Committee.

Lameness and injuries

  • For lameness and injuries, the Scientific Committee and their Research Writer reviewed 140 papers published between 1996–2020 with an emphasis on work published since the 2009 Scientific Committee report.
  • The broad topics included in their literature review were injury and lameness prevalence, risk factors (notably those related to the broad categories of housing, management, and cow-level factors), prevention strategies, early identification and treatment, and farm-level barriers to reducing occurrence.

End of life management

  • The Scientific Committee reviewed 21 studies (published between 1988–2020) covering the interrelated topics of euthanasia, culling, and fitness for transport. More specifically, recent research on the condition of culled cows at auction or slaughter were reviewed as was literature on producer training and other on-farm tools to help determine a cow’s fitness for transport prior to shipping.
  • In terms of down cattle, the Scientific Committee reported on appropriate nursing care and general factors that influence prognosis for down cattle.
  • Their review also spoke to factors that influence timely treatment and euthanasia for vulnerable cows.

Exercise and outdoor access

  • The literature review on this priority welfare issue reported on the effects that increased opportunities for movement have on various aspects of cow health and welfare, e.g. lameness and hoof health, injuries, reproduction, udder health, and lying behaviour.
  • This section of the Scientific Committee’s report summarized the findings of 51 papers published between 1977–2020.

Third meeting – January 6 and 7, 2020

The co-Chairs of the Scientific Committee presented several chapters of the research report completed to date, including cow-calf separation, pain control, and selected housing topics (i.e. stall design, bedding, air quality and temperature, and stocking density). Following these presentations, the Code Development Committee discussed the research findings and considered preliminary approaches to these topics in the updated Code of Practice and will continue these discussions in subsequent meetings.

The Code Committee also revised the husbandry chapter of the draft Code (e.g. stockmanship, milking, handling) and revisited certain sections of the feed and water chapter (e.g. milk feeding, weaning, feeding at pasture). Many of the topics discussed were identified as top-of-mind concerns in a survey launched at the start of this Code’s update.

The next meeting has been scheduled for March.

Second meeting – September 30 and October 1, 2019

This meeting was focused on reviewing the following updated chapters of the Code of Practice: health (e.g. calf health, calving management), feed and water (e.g. body condition scoring, pasture feeding), and euthanasia (e.g. timelines, training). The analysis from the survey asking for top-of mind thoughts on dairy cattle welfare was reviewed again as each chapter was considered. Beyond specific updates to the Code, all sections are being looked at with an eye to adding supporting context for requirements and recommended practices and highlighting research results, particularly studies published since the release of the 2009 Code of Practice.

The co-Chair of the Scientific Committee presented research on dairy calf feeding and weaning (summarized in the 2016 Scientific Committee report for the veal Code), and this was followed by an initial discussion about possible approaches to these topics in the Code.

One strength of the current dairy Code is its inclusion of group or herd level targets, and this type of bench marking was frequently raised in the September meeting. The committee identified a need to have a dedicated discussion on group- or herd level targets to consider additional data and the potential need for a consistent approach throughout the updated Code of Practice.

As part of a preliminary discussion on pre-transport considerations, the committee heard an overview of the new transportation regulations and considered themes/recommendations from reports on cull cow management and male dairy calf marketing, recently published by the National Farmed Animal Health and Welfare Council.

A comparison of international dairy cattle welfare standards has been prepared and is also informing the committee’s discussions on various topics.

The next meeting has been scheduled for January.

First meeting – July 3 and 4, 2019

The Code Development Committee attended a webinar orientation on the Code development process prior to this inaugural meeting allowing more time in the in-person meeting for committee members to get to each other’s areas of expertise, establish unique strategies for reaching consensus, and discuss priorities for the updated dairy cattle Code of Practice.  

Highlights of the meeting included an overview of the dairy industry today (including regional contexts) as well as the animal care module of proAction® (Dairy Farmers of Canada’s on-farm animal welfare assessment based on the current Code of Practice).

The committee also explored the main themes from a recent online survey intended to capture top-of-mind welfare concerns for dairy cattle and noted strong overlap between public and committee input on priority topics for this iteration of the Code.

Working with the project’s Scientific Committee (who were also in attendance), a list of priority welfare issues was agreed to (available here). These topics will form the basis of the Scientific Committee’s research report (the 2009 report is available here).

The next meeting is scheduled for the fall. In advance of that meeting, the Code Development Committee will begin working on draft sections of the Code. The Scientific Committee will begin its review of research on the priority welfare issues.
