Discussion

• June 7, 2022 notes were accepted as written.

• 2024 Sunsets: Tolazoline (ADB). The lead summarized the substance and also discussed the review of 

xylazine, which is used to reverse the effects of sedation caused by xylazine. The two substances used to 

undergo review at the same time, but during the sunset reorganization, they were split. The 

Subcommittee will add language to the review suggesting that both substances get reviewed 

simultaneously for the next sunset. The group moved to a vote.

Motion to remove tolazoline from the National List

Motion by: Amy Bruch

Seconded by: Kim Huseman

Yes: 0 No: 6 Abstain: 0 Recuse: 0 Absent: 0 

• 2024 Sunsets: Copper sulfate (NPP). The lead summarized the uses of copper sulfate and noted the 

environmental issues. Commenters noted essentiality, and acknowledged that zinc sulfate is an available 

alternative. A member suggested adding some language to the review about zinc sulfate, which the lead 

will do. The LS moved to a vote. 

Motion to remove copper sulfate from the National List

Motion by: Nate Powell-Palm

Seconded by: Brian Caldwell

Yes: 0 No: 6 Abstain: 0 Recuse: 0 Absent: 0 

• 2024 Sunsets: Lidocaine (NPP). The lead summarized the uses of lidocaine, which is used as an 

anesthetic. The community was supportive of lidocaine remaining on the National List based on its 

essentiality for animal welfare.

• 2024 Sunsets: Glucose (LG). Deferred to July 19 call.

• Research Priorities (RPs) (KH). The lead summarized comments from the Spring 2022 meeting regarding 

the Livestock Research Priorities. Members discussed several of the current RPs and whether or not they 

are still relevant and necessary, and should remain on the list. The Materials Subcommittee has been 

discussing other organizations research priorities, such as the Organic Farming Research Foundation, 

and will review both lists to compare and contrast. BC will compare the two lists and provide feedback 

on the next call. 

• Additional Items. 

o TRs for 2025 sunsets. The LS will not request TRs for phosphoric acid or biologics - vaccines, as 

previously decided, and instead will submit a couple of targeted questions about phosphoric 

acid alternatives.

Agenda

• January 4, 2022 notes

• 2024 Sunsets:

o Glucose (KH) - Discuss review

o Copper sulfate (NPP) - Discuss review

o Lidocaine (NPP) - Discuss review

• Additional Items 

• Adjourn

Discussion

• January 4, 2022 notes were accepted as written.

• Research Priorities. Members discussed the draft list of research priorities. Several commenters and 

NOSB members suggested removing one priority regarding Livestock breeding, because it seems too 

broad. Members discussed how to rescope this priority to narrow the focus. One member noted the 

potential link to climate change initiatives and another member added that research in this area would 

support the dairy industry. Members also revisited the topic of DL-methionine. The Chair will modify the 

document based on feedback from members and the group will discuss it more later this week to 

finalize it so they can get it to the Materials Subcommittee.

• 2024 Sunsets:

o Glucose (KH). Deferred to next call.

o Copper sulfate (NPP). The lead summarized the use of copper sulfate in livestock. A member 

noted that zinc sulfate, which is a recently new addition to the National List, is an alternative.

o Lidocaine (NPP). The lead summarized the draft review, and noted that at the last sunset 

review, the NOSB also passed a recommendation to reduce the withdrawal period from 90 days

to 8 days. Lidocaine is important to animal welfare, is generally supported by the community,

and has a low environmental impact. 

• Additional Items. None.

• The meeting was adjourned

Agenda

• December 7, 2021 notes

• Discuss 2024 Sunsets:

o Chlorhexidine (KH) - Discuss review

o Glucose (TBD/MJ-guest) - Determine TR sufficiency/discuss review, assign lead

• Research Priorities

• Additional Items 

• Adjourn

Discussion

• December 7, 2021 notes were accepted as written.

• 2024 Sunsets:

o Chlorhexidine (KH) - The lead summarized the uses of chlorhexidine, which is used as an 

antimicrobial during surgery, a sanitizer, and as a pre-and- post-teat dip. The group discussed 

the fact that there are alternatives to chlorhexidine on the list, and it is not used extensively, but 

important to have as an option. The lead will add a couple of questions to the review for public 

comment and will submit the document to the NOP for the Spring meeting. 

o Glucose (MJ-lead emeritus) - TR sufficiency. The lead emeritus (MJ) briefly summarized the TR

and the LS found it sufficient. KH will take the lead and will transfer it to one of the new 

members for presentation at the Spring meeting once they are appointed.

• Research Priorities - Members discussed the four research priorities for Livestock and chose to remove 

one: Research and develop livestock breeding programs resulting in livestock that are adapted to 

outdoor life and living vegetation. Members felt that this was too broad to be a research topic, and 

commenters suggested that it has already been done, and therefore it doesn’t need to be on the list. 

The LS Chair will summarize todays’ conversation and the LS will discuss the priorities once more on the 

January 18 call. 

• Additional Items. None.

• The meeting was adjourned
