Speaker
Today we're joined by Rachel Hart, Global Technical Marketing Consultant at Donesco Animal Nutrition and Health,
00:00:40
Speaker
a business of IFF.
Rachel Hart's Background and Career
00:00:42
Speaker
She's here to talk about recent research and development and using nutrition to reduce the environmental impact of poultry production.
00:00:50
Speaker
Hi, Rachel.
00:00:50
Speaker
How are you?
00:00:52
Speaker
I'm well, thank you, Jackie.
00:00:53
Speaker
How are you?
00:00:54
Speaker
I'm doing great.
00:00:55
Speaker
Thanks for being here.
00:00:57
Speaker
Well, let's get right into it.
00:00:58
Speaker
Tell us a little bit about yourself and your background.
00:01:02
Speaker
So I started with a degree in animal science from the University of Nottingham and then I jumped straight into industry.
00:01:12
Speaker
I started working in Danisco Animal Nutrition and Health 13 years ago now and I initially joined as part of our innovation team running animal studies.
00:01:23
Speaker
for products approaching launch before I moved into my current team in global technical marketing.
00:01:30
Speaker
My focus has always been really on the phytase products in particular, but I have worked across both swine and poultry.
00:01:38
Speaker
And then I've also done work across a lot of our products, so our carbohydrates is as well as our enzyme and probiotic combinations.
Insights from the European Poultry Conference
00:01:47
Speaker
Right now, earlier this summer you attended the European poultry conference, correct?
00:01:52
Speaker
Yes, that's right.
00:01:53
Speaker
Excellent.
00:01:54
Speaker
Now, can you please share a few of the research highlights or insights that you took away from the event?
00:02:02
Speaker
There's so many.
00:02:03
Speaker
It's such a big conference and it has so many sort of topics that are covered.
00:02:08
Speaker
I think the sort of main ones that I sort of found to be really interesting and sort of new to me
00:02:15
Speaker
was a lot of the work on the gut health, so the enterococcus and the coccidio stats, all that side of thing is expanding my knowledge base beyond what it has been.
00:02:28
Speaker
So I find that really interesting.
00:02:30
Speaker
But for me, the main sort of areas that I focus on at those events are all our customer interactions, actually having that face-to-face time and time to discuss what's happening in the industry is really invaluable.
00:02:45
Speaker
Now, from those customer conversations, any highlights, any trends that you're noticing?
Optimizing Enzyme Usage in Poultry Production
00:02:53
Speaker
For me, I spent a lot of my time talking about Phytase and sort of the potential of Phytase.
00:02:59
Speaker
I had some really good discussions around optimizing Phytase dose and sort of what benefits we can provide with full Phytase matrix applications and those sort of things.
00:03:12
Speaker
That's sort of, yeah, they're the take homes for me.
00:03:17
Speaker
So sustainability, of course, is a hot topic across industries.
00:03:22
Speaker
And of course, reducing the carbon footprint of animal production is a hot topic.
00:03:30
Speaker
How can precise feeding strategies be implemented to optimize roiler growth and performance while also maximizing nutrient excretion?
00:03:42
Speaker
Yeah, so...
00:03:44
Speaker
Enzymes play a pivotal role in that area really in sustainability and reducing the carbon footprint.
00:03:51
Speaker
And that all comes down to matrix application.
00:03:54
Speaker
So sort of the main areas of enzyme application, we have phytase, you have carbohydrates such as xylanase, and then we also have the protein, the protease section as well.
00:04:06
Speaker
And really they're currently underutilized I feel with matrix application.
00:04:12
Speaker
So for phytase, it's very successfully used for mineral matrix reduction, but we miss out on a huge chunk of the potential of phytases with energy and amino acid application for matrix values.
00:04:27
Speaker
And now even more so with like trace mineral application of matrix values.
00:04:32
Speaker
And the same with the xylanase and protease.
00:04:35
Speaker
Xylanase is considered an energy
00:04:38
Speaker
um matrix whereas the protease is just the amino acids and both of them can support both amino acid reduction and energy reduction as well which overall will help reduce phosphorus excretion and nitrogen excretion as well into the environment.
00:04:55
Speaker
So for those not familiar with the terminology will you please define um what matrix values mean in this context?
00:05:05
Speaker
Yeah, so matrix values is a common term that we use for the contribution of a nutrient that's supplied by the enzyme.
00:05:15
Speaker
So for phosphorus, for example, for phytase, for example, we often look at the starting point being the phosphorus contribution, which is based around the breakdown of phytate and the release of phosphorus.
00:05:31
Speaker
But as we look at interactions around the anti-nutrient of phytate, we see that phytate also has an impact in terms of energy utilization and amino acid utilization.
00:05:45
Speaker
So phytate is able to provide a contribution to your energy and to your amino acid nutrient ingredients utilization from the enzymes.
00:06:00
Speaker
in your overall feed formulation.
00:06:04
Speaker
Thank you for that.
00:06:05
Speaker
What strategies do you recommend for mitigating the environmental impact of phosphorus excretion in broiler production through nutritional interventions?
00:06:17
Speaker
Yeah, so I think one of the key things that when we talk about the role of phytase is that not all phytases are the same.
00:06:28
Speaker
And that to really utilize all the potential in terms of reduction of phosphorus excretion, you need a phytase that has a broad pH range.
00:06:39
Speaker
And that means that it's going to be highly active in the low pHs that we see in the upper GI tract.
00:06:47
Speaker
So sort of your pH 3, pH 3.5.
00:06:48
Speaker
And there, if you have the...
00:06:56
Speaker
the activity in those low pHs, that's when your phytase can act quickly and break down the phytate, releasing as much phosphorus as possible, but also reducing the anti-nutritional factor that phytate provides.
00:07:12
Speaker
And the phytate is also able to bind to protein and to calcium and trace minerals when it's in its full ester.
00:07:23
Speaker
So when it has six phosphorus
00:07:25
Speaker
phosphorus still bound to the phytate.
00:07:28
Speaker
And once you start to cleave that and break that down, then you're able to prevent that anti-nutritional impact.
00:07:37
Speaker
And I think we also need to understand the diet itself and the substrates that are specifically in the diet.
00:07:46
Speaker
So the recommendations that we apply for a diet that's low in phytate
00:07:52
Speaker
is going to be different for those diets that is high in phytate at that sort of 0.3, 0.33 level that we see in some markets.
00:08:01
Speaker
And we're also utilizing our understanding of limestone and limestone solubility, the calcium level in the diet, which are all key elements of how phytate interacts within the animal.
00:08:16
Speaker
How do you see the role of feed enzymes evolving in sustainable broiler production?
The Role of Feed Enzymes in Sustainability
00:08:23
Speaker
And if you could look at that both in terms of improving nutrient utilization and of course, reducing the environmental footprint.
00:08:33
Speaker
I think, I think one of the key elements we really need to understand and look at is how we can combine products, how you can use all the feed additives that we have in the industry to be most effective.
00:08:50
Speaker
So feed ingredients can be really complex.
00:08:53
Speaker
There's a lot that we need to look at in terms of making sure that we have the most sustainable industry that we can.
00:09:02
Speaker
We need to understand substrates, like I mentioned in my previous answer, but also we need to understand what alternatives are available if we want to fully reduce carbon footprint as much as we can.
00:09:17
Speaker
Recently, we've run a couple of studies that have actually looked at going totally soy free.
00:09:23
Speaker
And that's a really complex discussion to have because soy is so stable and it's used throughout the broiler industry in feeds, but the replacements aren't perfect.
00:09:37
Speaker
So when you look at things like canola meal or sunflower meal, they're higher in phytate, they have higher
00:09:44
Speaker
and soluble and insoluble NSP levels.
00:09:47
Speaker
And so in order to counteract those negatives of those ingredients, you need to look at an enzyme portfolio and a feed additive portfolio as well in order to replace the nutrients that are lost from moving from soy to those alternatives and still maintain the animal's performance.
Addressing Poultry Health Challenges
00:10:11
Speaker
So animal health and welfare is another aspect of the sustainability conversation.
00:10:18
Speaker
Will you please share your view on additive inclusions and how they are successfully addressing common health challenges, specifically in poultry, neurotic enteritis or coxidiosis?
00:10:32
Speaker
Yeah.
00:10:33
Speaker
So this is really a really interesting area that
00:10:38
Speaker
we're only just starting to sort of see the potential in.
00:10:42
Speaker
So historically probiotics have kind of been seen as the animal health space.
00:10:49
Speaker
And we've got some really positive responses and positive effects to the conditions that you mentioned in the question.
00:10:59
Speaker
But we really need to start understanding the role that nutrition plays as well.
00:11:05
Speaker
in the behavior of the microbes and the burden that we're seeing within the industry.
00:11:11
Speaker
So one of the areas we've looked at has been sort of with xylanase, for example, in terms of the prebiotic effect.
00:11:19
Speaker
So we get a boost in the beneficial bacteria that you can see in the distal GI tract.
00:11:27
Speaker
Protease can reduce crude protein in the diets and reduce the risk of things like necrotic enteritis blooms.
00:11:35
Speaker
but that just scratches the surface.
00:11:38
Speaker
Recently, we've run a phytase trial where we've actually looked at improving and optimizing the bioavailability of both iron and phosphorus in feed ingredients.
00:11:51
Speaker
And because of that, we've been able to show that
00:11:56
Speaker
we are able to reduce Compilobacter in the intestinal tract of broilers.
00:12:02
Speaker
And that's due to the fact that iron is key for the bacterial growth.
00:12:07
Speaker
And for the Compilobacter in particular, they need to find a way of easily utilizing and acquiring the iron that they need.
00:12:18
Speaker
But with Phytase, we've shown that we can remove the iron from the trace mineral premix and also
00:12:25
Speaker
reduce the phosphorus that is present in the diet and in the study that we ran we actually went completely inorganic pea free.
Strategies for Antibiotic-Free Poultry Production
00:12:33
Speaker
And what we were able to show in that study is that overall the level of iron and the phosphorus in the distal GR tract was reduced versus typical control.
00:12:46
Speaker
But in leading, but that reduction then further led to a reduction in compiler back to colonization
00:12:53
Speaker
the birds performance was still maintained.
00:12:56
Speaker
So yeah, overall, I think there's so much more that we can investigate for enzymes, and how they actually impact the health of the animals, and how they can support probiotics and that space.
00:13:13
Speaker
How is the industry balancing the need for optimal performance with the increasing demand for antibiotic free production?
00:13:24
Speaker
So yeah, I think this is really, as with anything in this industry, really we need a multifaceted approach.
00:13:32
Speaker
I think that husbandry plays a huge role in the ability to go truly antibiotic free, but also enzymes and probiotics are essential in order to optimize that process.
00:13:47
Speaker
Probiotics
00:13:48
Speaker
can promote and develop the beneficial bacterial populations, both within the environment as well as in the GI tract.
00:13:57
Speaker
And the enzymes are then used in that supporting role.
00:14:02
Speaker
Looking at 2025 and beyond, what area of sustainable roiler or, you know, more broadly livestock production do you think will see the most innovation?
00:14:16
Speaker
I think everything I've touched on throughout this conversation, really, soy-free, inorganic pea-free, antibiotic-free, they're all kind of in the early stages of their potential, really.
00:14:31
Speaker
So with all of those, we've kind of shown that it's possible.
00:14:36
Speaker
But now we need to be able to use our research to support people
00:14:42
Speaker
support the market and to give them the confidence that they can adopt these approaches and actually lead to a more sustainable industry as a whole.
00:14:53
Speaker
Excellent.
00:14:54
Speaker
Thank you so much, Rachel, for your time.
00:14:57
Speaker
And thanks to you for tuning in.
