  [SPEAKER_02]: And I would say I would go back to my initial comment about multivariate diet formulation, just to have them begin to think about including in ingredients in swine diets, that not only meet the nutritional requirement of the animal that are economically responsible, but also have the smallest carbon footprint or carbon intensity score or environmental footprint.
• 0:24
  [SPEAKER_02]: ends up being measured.
• 0:26
  [SPEAKER_02]: Our computer systems, our computer models and the calculators that we have available can easily handle that.
• 0:35
  [SPEAKER_02]: We just need to begin to think about that and that really helps our producers begin to tell their sustainability story in a much more robust way.
• 0:49
  [SPEAKER_01]: to want to thank the innovative companies and products who support and trust make this podcast possible.
• 0:54
  [SPEAKER_00]: Welcome to the Australian Nutrition Black Bell podcast, where we explore the science behind the Nutrition.
• 1:01
  [SPEAKER_00]: I'm your host, Horestra.
• 1:03
  [SPEAKER_00]: And today, our podcast, we have Chris Hofsteller, who is the director of Animal Science with the US National Board Board.
• 1:11
  [SPEAKER_00]: Today, we'll be discussing the work of the Nutri-metallization Consortium.
• 1:18
  [SPEAKER_00]: Dr. Hosteller, welcome to the podcast.
• 1:21
  [SPEAKER_00]: Thanks for joining us today.
• 1:22
  [SPEAKER_00]: Before we begin today's topic, could you please share a quick summary of your background with our audience?
• 1:30
  [SPEAKER_02]: Absolutely, Jorge.
• 1:31
  [SPEAKER_02]: Thank you for the opportunity to share a little bit about what the National Port Board has going on in the area of nutritional efficiency and sustainability.
• 1:41
  [SPEAKER_02]: As you said, I'm the Director of Animal Science.
• 1:44
  [SPEAKER_02]: I've been here for 14 years at the National Port Board Prior to that.
• 1:48
  [SPEAKER_02]: I was at South Dakota State University as a swine nutrition researcher there.
• 1:54
  [SPEAKER_02]: And prior to that, I worked for a long time for Washington State University in various roles, including management and oversight of their research and teaching swine farm.
• 2:05
  [SPEAKER_00]: Awesome.
• 2:06
  [SPEAKER_00]: Thanks for doing that.
• 2:07
  [SPEAKER_00]: And then, again, you know,
• 2:09
  [SPEAKER_00]: We're going to talk about a little bit about efficiency today and definitely this is a topic that for us in the nutrition world is very, very relevant.
• 2:19
  [SPEAKER_00]: So how does the strong nutrition feed into the vision of the national poor poor Chris?
• 2:26
  [SPEAKER_02]: Yeah, so for the last probably 15 years, I've been asked to think about production practices, including nutrition, reproduction genetics through sustainability lens and really think about how we can improve production efficiencies in all of those areas.
• 2:46
  [SPEAKER_02]: And I think probably one of the easiest ways to approach that is through nutrition, right?
• 2:52
  [SPEAKER_02]: because from a environmental footprint standpoint, the biggest driver of sustainability for poor production is the feed that we feed the animals, right?
• 3:04
  [SPEAKER_02]: And that's followed up very closely by the manure that they put out in the nutrients that are contained in that manure.
• 3:13
  [SPEAKER_02]: So if you just start to think about how
• 3:15
  [SPEAKER_02]: How you change your thinking about swine nutrition and begin to think about it through a lens of nutrient utilization, how nutrients are gained into that system, how nutrients are lost from that system, and you think about those efficiencies of nutrient transfer in each of those steps along the way.
• 3:37
  [SPEAKER_02]: So let's really be in the challenge for me over the last five years is to start to think
• 3:43
  [SPEAKER_02]: How we can better utilize the nutrients that are available to us to raise pork and to provide a healthy product for humans to consume.
• 3:55
  [SPEAKER_00]: Great.
• 3:55
  [SPEAKER_00]: Well, until this topic is about, you know, the nutrient utilization construction.
• 4:01
  [SPEAKER_00]: Why don't you tell us a little bit about that?
• 4:03
  [SPEAKER_00]: What is it about?
• 4:04
  [SPEAKER_02]: Yeah, so I think it was 2023.
• 4:08
  [SPEAKER_02]: We got together with a group of producers and other subject matter experts and really to tease out this idea of the decisions that we make in
• 4:21
  [SPEAKER_02]: One area of the production cycle really can affect the downstream impact in the other areas.
• 4:30
  [SPEAKER_02]: So for example, if we feed fithase in swine diets, which many producers do, that greatly reduces the amount of phosphorus that is excreted from the pig.
• 4:40
  [SPEAKER_02]: And so that phosphorus would go into the manure would be taken up by the corn plant and used to produce grain.
• 4:47
  [SPEAKER_02]: That phosphorus would be then in the grain and would be transferred back into the pig, right?
• 4:51
  [SPEAKER_02]: So that decision to make to feed, to include microbial fightays in swindites really has a downstream impact on lots of other portions of the
• 5:07
  [SPEAKER_02]: pork ecosystem, it's called right, and the circular economy of pork.
• 5:11
  [SPEAKER_02]: And so, we, during that brain storming session, we thought about how we can, can better define the, the nutrient use throughout that system, what data is needed to help us unbetter understand, and
• 5:29
  [SPEAKER_02]: The nutrient transfer we talked about how producers can begin to utilize environmental footprint data in their diet formulation, so if you think about multi-variate diet formulation, you know, certainly nutrient.
• 5:50
  [SPEAKER_02]: requirement being the first overlayed by economics, the cheapest nutrient ingredient that we could add, and then a third layer would be the environmental footprint information.
• 6:05
  [SPEAKER_02]: So we talked about that.
• 6:07
  [SPEAKER_02]: And we talked about the antiquated nature of many of the databases that are currently available.
• 6:20
  [SPEAKER_02]: really higher a consortium of subject matter experts who can spend the next five years working in this space in nutrient utilization.
• 6:33
  [SPEAKER_02]: So,
• 6:33
  [SPEAKER_02]: The consortium is led by Laura Griner at Iowa State University.
• 6:37
  [SPEAKER_02]: She's a friend of the podcast.
• 6:39
  [SPEAKER_02]: And so Laura is leading, doing a great job of leading that group.
• 6:45
  [SPEAKER_02]: There are four universities in another institution, I-feeder is represented on the consortium.
• 6:53
  [SPEAKER_02]: There are production companies that are involved either in a collaborating or a supporting role as well.
• 7:03
  [SPEAKER_02]: way for us to be very coordinated and cooperative in the research that is done in that space.
• 7:13
  [SPEAKER_00]: Awesome, and then just to recap a little bit the idea, Chris, could you tell us from the, what is the priority from the nutrient utilization standpoint?
• 7:26
  [SPEAKER_00]: How is the group going to start and where
• 7:33
  [SPEAKER_02]: Yeah, so certainly the first thing that they did was they conducted true to fashion, right, conducted a series of literature reviews for the different sectors that would be represented in the circular economy of poor production.
• 7:52
  [SPEAKER_02]: And so those literature reviews are really designed
• 8:02
  [SPEAKER_02]: help the consortium better understand where data needs to be included, where it needs to be updated, what kind of information that we're lacking, and really to begin the process of almost standardizing.
• 8:19
  [SPEAKER_02]: life cycle assessments for pork production and so everything that we do from a nutrition standpoint really underpins life cycle assessments which are used to assess the environmental footprint of pork production and so
• 8:38
  [SPEAKER_02]: Right now we use these sort of databases that may be antiquated or maybe at least outdated need to be updated.
• 8:46
  [SPEAKER_02]: And so that was the very first step in the process was to identify those gaps in information.
• 8:54
  [SPEAKER_02]: And now they've been doing research over the last two years to really begin to fill in that information.
• 9:01
  [SPEAKER_02]: And so for example, of that is the GFLI database is a global database on feed ingredients, the LCA's or the footprint environmental footprint of various feed ingredients.
• 9:18
  [SPEAKER_02]: And we didn't have any U.S. data to back up corn, soybean meal, wheat, wheat, mids, harmony, those types of feed ingredients.
• 9:28
  [SPEAKER_02]: Laura Moody at Ifeater has been working with the GFLI database to include US ingredients into that database and that really allows us to conduct a much better, much more robust LCA around poor production in the U.S.
• 9:47
  [SPEAKER_00]: Awesome, yeah and as you're saying, a lot of that information needs to be, you know,
• 9:53
  [SPEAKER_00]: within the same place and space that way we can access it and use it, right?
• 9:57
  [SPEAKER_00]: So getting into that, you know, I mean, this is an nutrition podcast for so I got to ask this.
• 10:02
  [SPEAKER_00]: So how can the nutrition is use the information that comes out of the construction then?
• 10:08
  [SPEAKER_02]: Yeah, so I think about the nutritionists that work for production companies, right?
• 10:13
  [SPEAKER_02]: What's in it for them and how, how is it that they can utilize this information?
• 10:17
  [SPEAKER_02]: And, and I would say I would go back to my initial comment about multi-variant diet formulation.
• 10:23
  [SPEAKER_02]: just to have them begin to think about including in ingredients in swine diets that not only meet the nutritional requirement of the animal that are economically responsible, but also have this smallest carbon footprint or carbon intensity score or environmental footprint.
• 10:42
  [SPEAKER_02]: However, however that
• 10:43
  [SPEAKER_02]: ends up being measured.
• 10:45
  [SPEAKER_02]: Our computer systems, our computer models and the calculators that we have available can easily handle that.
• 10:54
  [SPEAKER_02]: We just need to begin to think about that.
• 10:57
  [SPEAKER_02]: And that really helps our producers begin to tell their sustainability story in a much more robust way.
• 11:05
  [SPEAKER_02]: And I think that is, we've often said that we do what's right for people, pigs and planet.
• 11:16
  [SPEAKER_02]: But until we actually put some of that into practice, those are just words, right?
• 11:21
  [SPEAKER_02]: And so being able to prove that we are being good stewards of our environment, good
• 11:32
  [SPEAKER_02]: I think that's the important part.
• 11:36
  [SPEAKER_00]: So you're telling us that at the end of the day with this information, we could potentially use the kind of the carbon footprint as one of the variables used in order to optimize diets, right?
• 11:50
  [SPEAKER_02]: correct.
• 11:51
  [SPEAKER_02]: And so theoretically you could develop a diet that has a high carbon footprint on a low carbon footprint, right?
• 11:58
  [SPEAKER_02]: And you could, you could interchange between those diets based on their ingredients.
• 12:04
  [SPEAKER_02]: You could interchange between those diets.
• 12:07
  [SPEAKER_02]: You could use that information.
• 12:09
  [SPEAKER_02]: It's been sustainability related information is becoming increasingly important.
• 12:13
  [SPEAKER_02]: for our lenders, for our downstream partners, our retail partners in port production.
• 12:21
  [SPEAKER_02]: And so being able to have that as one of our proof points, I think is extremely important.
• 12:29
  [SPEAKER_00]: Great.
• 12:30
  [SPEAKER_00]: So one more question, Grace.
• 12:33
  [SPEAKER_00]: So what can nutrition is actually access the information and action.
• 12:38
  [SPEAKER_00]: I'll, you know, all comes that you guys are putting together.
• 12:41
  [SPEAKER_02]: Right, so in two to form, those literature reviews have been published in the Journal of Animal Science as a series of companion papers, and so certainly are more scientific, swine nutritionists can go there to find the scientific articles that have been written
• 13:00
  [SPEAKER_02]: And the sort of the actionable outcome information will be housed at the Iowa Pork Industry Center on their website.
• 13:11
  [SPEAKER_02]: And so that would be ultimately the repository for this body of data.
• 13:17
  [SPEAKER_02]: Again, that's the Iowa Pork Industry Center.
• 13:20
  [SPEAKER_02]: And anybody can access that information.
• 13:23
  [SPEAKER_02]: They already have a wealth of white papers and short videos and things like that that are there but this information will be managed in a very interesting way.
• 13:34
  [SPEAKER_00]: Well, that's all the time that we have today Dr. Hosteller.
