Interview with Dr. Francine Van Simbeek
00:01:01
Speaker
In today's episode, my guest is Dr. Francine Van Simbeek, poultry technical consultant at Elanco. Thanks for joining us today, Francine.
00:01:10
Speaker
Thank you so much for the invitation. Can you explain the difference between a bio-shuttle and a medicated starter in terms of an anti-coccidial program? Well, sure. Be glad to. I will preface the question you just asked by saying that I'm only going to be addressing the no antibiotics important to human medicine or the NAIHM programs today. We can save the no antibiotics ever or the NA programs for a later time. So a bio shuttle and a coccidial program, it utilizes a coccidial vaccine at the hatchery, typically on day one old chicks.
Understanding Bio-Shuttle Programs
00:01:44
Speaker
And then that vaccine is allowed to cycle in the birds on the farm. typically up to about 16 to 18 days. And then for a bio shuttle, you put an anticoxidial product in the feed to help manage that coxidial peak cycling.
00:01:59
Speaker
This will decrease the amount of damage that occurs in the intestinal cells of the chicken. we like to call it dampening the coccy peak. So this type of program really supports gut health,
00:02:11
Speaker
nutrient absorption while still allowing a controlled coccidial exposure. And that allows the birds to develop immunity to this particular intestinal parasite. The types of in-feed anticoccidial products that we generally use are ionophores or weak chemicals in a bio-shuttle program.
00:02:30
Speaker
And they're usually put in either in the second feed or potentially the second and third feeds, really depending upon what your program calls for and what kind of control you're looking for. So that's a bio shuttle. So when we talk about another program where we use a medicated starter, we can build a very similar immunity without using that vaccine by putting the anacoxid medication in the starter or what we typically consider the first feed that those chickens eat.
00:02:59
Speaker
I call this a straight anacoxidil program as we are not shuttling from one control program to another like we do in a bio shuttle program, hence the name.
00:03:11
Speaker
By having anacoxidil drugs in the feed from the very start, We can reduce or sometimes even prevent coccidial infection outright, and it really provides a more immediate coccidial control to that bird.
00:03:26
Speaker
The amount of control that we can get will depend on which type of anacocidial product you choose.
Impact of Programs on Flock Management
00:03:34
Speaker
Products that can be used for either program, BioShuttle or a straight program include ionophores, weak chemicals, and strong chemical anticoxidials, all of which have their own strengths and weaknesses. So the choice, it really needs to be considered very carefully. what you want to use.
00:03:52
Speaker
The birds will still develop immunity to coccidiosis, but with decreased intestinal damage if you have some kind of medicated product in the feed. Without this gut damage, the bird's much less likely to develop necrotic enteritis, which is a bacterial overgrowth in the intestines that can lead to some really high mortality if that's not controlled by antibiotics and management. So that's kind of the difference between a bio-shuttle and having an in-feed medicated program.
00:04:19
Speaker
How does the choice between a bio-shuttle versus medicated starter impact flock management, disease pressure, and performance? Oh, that's a really good question. So let's address the management part first.
00:04:31
Speaker
Bio-shuttle programs, they may require more careful monitoring of the vaccine uptake and the early bird health. as we are relying solely on that bird's immune response to clear the vaccine, at least initially, until the second feed when the medicated products are introduced.
00:04:50
Speaker
With in-feed medicated programs, the control program is with the birds in every mouthful, providing consistent protection. There are times when we will rotate the infeed products to prevent resistance buildup. And those strategies are best discussed with an Elanco technical consultant that's familiar with your specific needs and what your previous anticoxido programs were.
00:05:15
Speaker
Other management issues that we need to look at are the density of the bird placement in a poultry house. We want to maximize the number of birds in a house while still providing them with optimal growing conditions in which they can thrive. In a vaccine-only situation, the producers may choose to place less birds in a poultry house to decrease the disease pressures. But then there is an economic and sustainability cost to placing less birds in a house.
00:05:44
Speaker
In the end, it will require more poultry houses to raise the same number of birds, which requires more construction costs and land use devoted to poultry rearing. And that will impact our sustainability and how we can manage future bird growth.
00:05:59
Speaker
Regarding the disease pressure angle, as previously mentioned, necrotic enteritis is a major concern when using vaccines by themselves or what I call a naked vaccine program.
Factors Influencing Program Efficacy
00:06:10
Speaker
BioShuttles, which again medicate the second and or second and third feeds, it supports long-term immunity with a reduced fear of necrotic enteritis developing as we control the damage occurring in the intestine due to that vaccine cycling.
00:06:28
Speaker
Medicated starters, because they're present from day one in the bird's life, really protect the intestinal integrity of the birds by providing a more immediate disease control, which can lead to improved growth performance and productivity.
00:06:42
Speaker
What are some key factors in different production systems that influence your recommendations when choosing between interventions to maintain intestinal health and flocks? Really good question. And I may get a little long-winded on this one because there's a lot of different things we really have to stop and consider. So just to preface again, today I'm really concentrating on the NAIHM programs rather than NAEHM.
00:07:05
Speaker
So when I look at intestinal health programs to what I want to implement for that particular company, it's not going to be the same for everybody. It's going to depend on what is my current climate? What kind of management? Do I have any disease pressures from the past that might still be present in my poultry houses? Where is my final poultry product going to be sold And then there are other factors. So let me address those issues.
00:07:32
Speaker
Let's do management first. So management variables, they include things like the stocking density or how many birds are we placing in a poultry house. I go in and look at how is the litter quality look? How is the ventilation? What is my water and feed quality like? Because all of those variables play a part in the challenges that birds going to face in maintaining their intestinal integrity and, quite frankly, thriving in a modern poultry house.
00:07:57
Speaker
And what we discussed in the last question around sustainability, that can also be impacted when we change management, like our stocking density, or even the quality of the feed in terms of of growth rates or how fast that bird can grow.
00:08:11
Speaker
When I choose to use an in-feed medication for coccidial control, it really helps us manage the coccidia that's present through the feed on multiple producers' houses where the management may vary.
00:08:26
Speaker
considerably based on the age of the poultry house itself or if that housing has good litter and ventilation. Not every poultry grower has the same equipment or experience. So variation can certainly creep into our systems and lead to variation of how good our birds are going to grow. By choosing to medicate the feed, we try to reduce that variation and provide consistent product.
00:08:48
Speaker
Looking at the Climate angle, if I'm working with somebody that's in a hot and dry area, bio shuttles work well as the vaccines may be more effective where that environmental challenge is what I would call moderate. So hot and dry.
00:09:04
Speaker
Summertime is the peak time of year that I see bio shuttles utilized. That's when the vaccines typically get used. In a high challenge situation, like humid and wet conditions, which quite frankly is usually experienced in wintertime, in-feed medications tend to provide me a more consistent and immediate control of coccidial issues.
00:09:27
Speaker
Often we say that our wintertime is our most challenging time of the year to grow chickens. And so that's where I'm going to target putting my best control program. And so typically that's going to be in the wintertime.
00:09:40
Speaker
I absolutely want to know what previous programs the producer has been on because I need to know how the rotation of products was
Monitoring Bird Health with HTSI
00:09:49
Speaker
accomplished. If I can have that information, i can look at how the birds performed on those previous programs and look at those previous results.
00:09:58
Speaker
We do offer a service called HTSI or the Elanco Health Tracking System to monitor bird health and track how the birds responded the different anacoxetal programs over time. What I love about this is it allows us to make Data-driven decisions rather than just gut feelings on, well, I think that program did okay or that one I don't really care for. So I'd rather have some data behind what my choices around anticoxido products are based on.
00:10:27
Speaker
I can give you another example. We recently were working with a company that had been on a naked vaccine program for a couple of years. We did advise them to try our combination Narosin-Nicarbazine product, but it's called MaxiBand, and use that in a straight program instead. We tracked them in our HTSI system, and then over the next set of grow-outs, this company improved its FCR, or feed conversion ratio, 10 points.
00:10:54
Speaker
And to give you some math, with each point of feed conversion costing approximately $8,000 per week, or even more if it's a Big Bird complex, when you start saving $8,000 a week, it can really start stacking up. And it certainly did for this particular company.
00:11:09
Speaker
I love using HCI as a monitoring tool for the antioxidant control. And within that system, we also look at other health issues that might be impacting overall bird health. If I choose to do a bursal survey ready to explore infectious bursal disease virus, because that can create immune problems in our birds, that's something we've been dealing with for decades.
00:11:29
Speaker
poultry industry has known about that one for a long time. But we also get new things that come into our health system, like the AMPV or avian metanumovirus. It's a very recent virus impacting the U.S. poultry market, and we need to know how to deal with that issue. So we do track that one in our system.
00:11:45
Speaker
And then finally, i think looking at where your final product distribution goes, and it really depends on which company or even which country you shipped your finished poultry product to. And that may limit what products you
Integrating Vaccines into Management
00:12:00
Speaker
can use in the feed. Here at Elenka, we are certainly glad to assist you in each of the areas I talked about in order to make the best strategic and a coccidia program for your production system.
00:12:10
Speaker
What is the most effective way to integrate a vaccine into coccidiosis management program? I would say time of the year that you want to implement is super critical.
00:12:22
Speaker
What I covered before, summertime is the good time to do this kind of a vaccine introduction is we can typically manage the house conditions better during those hot, dry periods more effectively than during the cold, wet times of year. And then certainly if we do a bio shuttle where we utilize like a medicated second feed, we can deliver that vaccine at the optimal stage and then control that cycling maximize performance for our birds.
00:12:50
Speaker
We're going to look at how can we use best practices in terms of the management, which I previously described, yeah maintaining litter quality, water quality, and feed consistency in order to really optimize the intestinal integrity of that bird and get the best performance out of them that we can. I am going to monitor how those birds are doing in terms of of looking at the growth rate and flock health.
00:13:14
Speaker
We certainly want our poultry producers to have the best experience on those products. And we want those birds to also develop proper immunity to the coccidial vaccine that we're trying to do We use HTSI to monitor for that.
00:13:27
Speaker
So its Elenco representatives are good at the HTSI systems, but we also are available to go poultry houses and look at management variables themselves and see how those birds are dealing in that particular situation. So if we see an issue, we can certainly make recommendations on how to resolve that issue early before the problem really becomes overwhelming and blows up in that chicken house. So think that's some of the ways we can help you integrate a vaccine into the N-Cocsidio program.
00:13:59
Speaker
For anyone that needs additional support on integrating a vaccine into coccidiosis management program, how can they access resources? I myself am a technical consultant with Elanco and I love to help people tailor either an effective bio shuttle program or a straight unconscionated program. Love to look at how we can put some best practices in place around how we're managing feed. so I would actually encourage our listeners to reach out to us at Elanco for help and advice that we can give them as technical consultants, product recommendations. And we are more than happy to be here of a service to culture
