00:00:05.030 --> 00:00:08.250
Welcome to the Poultry Keepers Podcast we're happy you joined us.
00:00:08.740 --> 00:00:17.260
In this episode, Jeff Mattacks, Carey Blackmon, and Rip Stallvee are discussing the importance of vitamins and minerals in poultry diets.
00:00:17.730 --> 00:00:18.719
So let's get started.
00:00:19.143 --> 00:00:19.164
Yeah.
00:00:19.164 --> 00:00:20.743
Yeah.
00:00:29.141 --> 00:00:35.591
We're going to be talking about vitamins, minerals, and metabolizable energy.
00:00:35.671 --> 00:00:40.101
I've been getting some, a lot of questions about that here late, so I thought it was time to bring it up on the show.
00:00:40.902 --> 00:00:48.512
So Jeff, just to get us started, are the purpose of vitamins in poultry diets.
00:00:49.311 --> 00:00:51.542
Most of them are to support health, right?
00:00:51.601 --> 00:00:52.381
You know what I mean?
00:00:52.652 --> 00:00:57.792
Like your vitamin A is really important for your retinols and stuff like that.
00:00:57.862 --> 00:01:04.751
And keratin for like eye and different internal organs that play a little bit in skin.
00:01:05.302 --> 00:01:08.421
Vitamin E is going to be your immune system support.
00:01:08.632 --> 00:01:20.921
As well as it also is going to aid the skin, both A and E are going to transfer because a hen requires a higher level of vitamin A and E than like a growing or developing bird.
00:01:21.552 --> 00:01:24.341
A lot of that gets deposited into the egg.
00:01:24.837 --> 00:01:29.947
For either you to eat or the chick B vitamins or your calming vitamins.
00:01:30.016 --> 00:01:33.927
Again, they also have, they're going to support healthy liver function.
00:01:34.356 --> 00:01:36.936
A lot of those get deposited in the egg as well.
00:01:37.436 --> 00:01:41.897
They just they're drivers, so to speak body systems and.
00:01:42.447 --> 00:01:52.966
Yeah, vitamin D, that's your sunlight vitamin, but a lot of birds don't really get enough and they're finding a connection between vitamin D and actually immune system support as well.
00:01:53.387 --> 00:02:02.576
Before vitamin D was often ignored and it was felt that, 30 minutes of sun exposure would get develop all the vitamin D you actually needed.
00:02:02.966 --> 00:02:10.586
While they're rethinking that And they're saying that vitamin D pretty much in all living species does play a beneficial role.
00:02:10.796 --> 00:02:17.766
Vitamin D also is key for your calcium absorption, so it's going to be tied into your eggshells.
00:02:18.266 --> 00:02:19.266
There's your quick rundown.
00:02:20.067 --> 00:02:21.497
So I have a question real quick.
00:02:21.977 --> 00:02:31.437
In reference to the vitamin D, Does when you're using artificial lighting, does that help or hurt or make a difference?
00:02:32.236 --> 00:02:34.516
As long as it's full spectrum, right?
00:02:34.556 --> 00:02:41.776
And they're getting the right wavelength, then the birds going to be able to process some vitamin D from that.
00:02:42.407 --> 00:02:50.206
And the vitamin D levels like, that I recommend in the feed 1500 to 2000, you're still safe.
00:02:50.276 --> 00:02:52.616
It's not like you're overdosing on the vitamin D.
00:02:53.192 --> 00:03:17.891
Honestly, I'd like to see vitamin D closer to 3, 000, but there's no data to support that, and I don't want to be the only lone lunatic out there doing it, but I could see benefits of vitamin D levels at 3, 000, um, especially when birds are being challenged or, really been laying for a long time and haven't had a proper mold, things like that.
00:03:18.472 --> 00:03:18.491
Yeah.
00:03:19.097 --> 00:03:22.757
We don't honestly know the right, the perfect level for vitamin D.
00:03:23.206 --> 00:03:31.616
The whole poultry community, what they study is what is the minimum requirement, not what is the optimum requirement.
00:03:32.236 --> 00:03:37.086
So they're always worried about saving a nickel or saving a dime, right?
00:03:37.146 --> 00:03:45.937
So they're looking at what is that kind of that least number to not jeopardize production.
00:03:46.271 --> 00:03:47.872
First and health second.
00:03:48.252 --> 00:03:51.972
So like I said, we don't really know what an optimum level is.
00:03:51.991 --> 00:03:55.282
What we know is required level is okay.
00:03:55.831 --> 00:03:57.771
And those aren't the same thing, right?
00:03:58.181 --> 00:04:04.042
Like I only require one scoop of ice cream, but I do a whole lot better on three.
00:04:04.472 --> 00:04:05.842
So yeah,
00:04:06.211 --> 00:04:06.722
three, four
00:04:06.722 --> 00:04:10.331
is the problem.
00:04:10.331 --> 00:04:11.241
I'm good at three.
00:04:11.331 --> 00:04:11.641
So
00:04:12.442 --> 00:04:27.521
Jeff, you were talking about optimum levels and minimum levels, and I wish more people would realize that what they're seeing published are those minimum levels and they see those and they think, oh man, I'm good to go.
00:04:27.581 --> 00:04:29.932
But oftentimes that's just not the case.
00:04:30.507 --> 00:04:33.997
Well, a lot of folks aren't even looking at what the requirements are.
00:04:33.997 --> 00:04:41.336
Sadly, people make the assumption that the feed company is putting the right level in the feed.
00:04:42.137 --> 00:04:54.177
And they're going off of there's a, it's called national research council and our C values and you, anybody can look these up, you can look up NRC values for laying hands.
00:04:54.257 --> 00:04:54.526
Okay.
00:04:54.526 --> 00:04:57.976
That's going to be only for commercial laying hands.
00:04:58.586 --> 00:05:04.076
And what is that, recommended, what is that required value?
00:05:04.846 --> 00:05:07.826
And that gets updated about every 10 years.
00:05:07.836 --> 00:05:18.637
So it could be old, could be not depending on when they updated it last, but that's the NRC values, National Research Council, people are welcome to go out there and dig around.
00:05:18.666 --> 00:05:19.916
It's really dry.
00:05:20.357 --> 00:05:27.516
It's hard to actually find what you want, but it is a published document and it can be found on the internet.
00:05:28.317 --> 00:05:34.857
And that's where PhDs around the world, based on research studies and what they've learned.
00:05:35.211 --> 00:05:41.591
They come to a conclusion and say, we believe that a chick needs this to get its life started.
00:05:42.141 --> 00:05:48.922
And like the 3000 units of vitamin A, the 1000 units of vitamin D, 10 units of vitamin E.
00:05:49.302 --> 00:05:50.802
And those are the bare minimum.
00:05:50.841 --> 00:05:53.132
Those are the numbers that, they run with.
00:05:53.762 --> 00:05:57.541
And then there's so much that gets set on those numbers, right?
00:05:57.541 --> 00:06:01.502
There's so much emphasis being placed on the NRC values.
00:06:01.531 --> 00:06:10.831
There again, nobody's publishing optimum values and nobody really has researched optimum values, particularly in the vitamin world.
00:06:10.872 --> 00:06:12.122
Not that I've seen, right?
00:06:12.141 --> 00:06:13.461
I'm not saying it's not out there.
00:06:13.822 --> 00:06:16.031
I'm saying I haven't found it so far.
00:06:16.581 --> 00:06:22.841
They're starting to have more and more, like they're always doing amino acid work.
00:06:22.882 --> 00:06:25.721
They're always doing, there's always something going on out there.
00:06:26.172 --> 00:06:31.841
But the PhD community and the large poultry community keep it a secret within their small circles.
00:06:32.232 --> 00:06:37.211
So they don't release it to us until it's, 10 or 15 years old or older.
00:06:37.851 --> 00:06:41.341
So we have to learn it the hard way, but that's all right.
00:06:41.612 --> 00:06:42.021
That's all right.
00:06:42.122 --> 00:06:43.211
We're doing fine.
00:06:43.461 --> 00:06:44.732
We are doing good.
00:06:45.471 --> 00:07:03.002
I'm sure a lot of people, they don't want to take their best bird that's perfectly healthy, looks great, go do a necroposy and pull some blood work and see what its levels are to find out what those, great levels would be.
00:07:03.502 --> 00:07:11.312
And that would be about the only way you would take some very healthy birds and run those tests.
00:07:12.112 --> 00:07:12.281
Yeah.
00:07:12.312 --> 00:07:16.341
And I don't even know if they have standards for the vitamins.
00:07:16.461 --> 00:07:19.692
Most blood work is done on vitamin or on mineral work.
00:07:20.401 --> 00:07:22.182
And here's the thing about blood work, right?
00:07:22.432 --> 00:07:31.182
If you, if any of us goes to a lab to get blood work, the majority of the blood they're going to pull, we have to do a fasting diet.
00:07:31.211 --> 00:07:35.041
So they want to know that you haven't eaten in 12 hours.
00:07:35.632 --> 00:07:36.762
Here's the thing, right?
00:07:36.791 --> 00:07:45.401
So you would have to fast your chicken to get a true number because if it ate 10 minutes ago or it ate half an hour ago.
00:07:46.201 --> 00:07:52.992
So blood values can change really quickly depending on how good the digestive tract is or isn't.
00:07:53.492 --> 00:07:57.971
So you know, yeah, again, nobody set this standard.
00:07:58.041 --> 00:08:00.812
So if you feed your chickens at eight o'clock in the morning.
00:08:01.141 --> 00:08:03.781
Do we pull blood at two o'clock in the afternoon?
00:08:04.331 --> 00:08:04.901
I don't know.
00:08:04.971 --> 00:08:08.312
And not all chickens eat exactly at the same time.
00:08:08.822 --> 00:08:18.711
When I had my chickens in the backyard, then, some, every time you went to the feeder, 80 percent of them ran up to the feeder and they ate something.
00:08:19.007 --> 00:08:26.396
But there was always 20 percent that were more interested in a grasshopper or, finding an earthworm or cricket, whatever.
00:08:26.826 --> 00:08:32.807
And they weren't as dependent or as interested in the feed.
00:08:33.606 --> 00:08:42.136
I don't know, getting blood work to have a good number and know if you're even on track or not again, when did he last?
00:08:42.147 --> 00:08:43.076
What are they eating?
00:08:43.626 --> 00:08:44.076
I don't know.
00:08:44.736 --> 00:08:46.206
It would be great to know.
00:08:46.277 --> 00:08:49.996
I would love to know what optimum levels are now.
00:08:50.057 --> 00:08:50.956
I don't know.
00:08:51.466 --> 00:08:52.876
I know they're doing divided.
00:08:53.197 --> 00:08:54.856
You can do D through blood.
00:08:55.236 --> 00:09:05.177
And I know you can do some of the B's through blood, but I have not seen I have not seen like A, E, some of the other.
00:09:05.427 --> 00:09:06.966
I don't know if they can do them or not.
00:09:07.206 --> 00:09:14.966
David brought up there are new NRC tables, but he thinks the latest are from 1994, and they very well may be for poultry.
00:09:15.017 --> 00:09:17.736
I don't know when they've been updated last.
00:09:18.116 --> 00:09:22.147
They don't update each species every time they do an NRC update.
00:09:22.947 --> 00:09:30.787
Let me, let's kind of shift gears here and let's talk about some specific vitamins, basically what do they do?
00:09:31.287 --> 00:09:34.956
And what level should we be looking for in our nutrition?
00:09:35.496 --> 00:09:36.976
Let's talk about vitamin A.
00:09:37.017 --> 00:09:43.687
Now you've already mentioned it supports vision, the immune system function skin, anything else?
00:09:44.076 --> 00:09:44.336
Yeah.
00:09:44.336 --> 00:09:45.211
Something in the feather.
00:09:45.322 --> 00:09:51.052
Some of it's going to, if there's enough of it, it's going to support proper follicle and feather growth.
00:09:51.572 --> 00:09:55.172
It's going to be there, which is, that's part of the whole skin structure as well.
00:09:55.692 --> 00:10:01.072
A little bit in the muscle tone sort of thing, muscle growth, development, and tone.
00:10:01.662 --> 00:10:04.282
Most of it's going for like nervous system.
00:10:04.322 --> 00:10:18.527
I, skin, feather is where I see most of it going that's, and it's got a direct connection to things like iron, and the absorption of iron and it's going to, again, a large portion of it's going to go into the egg.
00:10:18.966 --> 00:10:25.606
If there is a large portion, there's a large portion going to go into the egg and or the development of egg.
00:10:26.407 --> 00:10:29.687
You were talking about the follicle and that sort of thing.
00:10:30.486 --> 00:10:39.246
Occasionally, I'll see a bird that has retained part of the feather sheath as the feather grows and you'll see real ready looking feathers.
00:10:39.267 --> 00:10:43.136
But sometimes you can break that off of there and they'll come out of that.
00:10:43.136 --> 00:10:45.797
But could that be related to vitamin A?
00:10:46.417 --> 00:10:47.017
It could be.
00:10:47.096 --> 00:10:48.397
It is.
00:10:48.777 --> 00:11:00.216
I, it, in part, I believe that the vitamin A is driving some of that, that sheathing is not, isn't, didn't develop right when it was still in the body.
00:11:00.601 --> 00:11:01.841
And that feather was pushing,
00:11:02.371 --> 00:11:03.851
That's exactly what it looks like.
00:11:04.611 --> 00:11:20.162
And, so it just didn't, the, that, that sheathing didn't actually fully develop so that it can break away and, and fall off or the feather underneath that sheathing wasn't strong enough to do its job and push the sheathing off.
00:11:20.261 --> 00:11:23.672
But yeah, I could see vitamin A being a direct connection to that.
00:11:24.037 --> 00:11:30.616
And whether that might be more of like the, so the retinol is going to be more your nervous system.
00:11:30.616 --> 00:11:40.206
And I, that's probably more in the carotene family not carotene, carotene, c a r o t e n e.
00:11:40.767 --> 00:11:44.076
But I think, that's going to be more in that carotene.
00:11:44.576 --> 00:11:46.777
Family of vitamin A's are split.
00:11:46.807 --> 00:11:49.576
There's several different sources of vitamin A.
00:11:50.076 --> 00:11:51.456
There's beta carotenes, retinols.
00:11:51.687 --> 00:11:54.197
They're not all just straight up vitamin A.
00:11:54.706 --> 00:11:57.317
Diversifying where your vitamins come from.
00:11:57.927 --> 00:12:02.886
And this is a big reason why I push alfalfa meal in almost all of my feeds.
00:12:03.272 --> 00:12:13.701
is I'm getting a whole different set of vitamin A's from a green leafy, vegetation like alfalfa carries a high vitamin A.
00:12:14.142 --> 00:12:21.121
And it actually is one of the few plants that retains that vitamin A because it can retain its chlorophyll and its color.
00:12:21.642 --> 00:12:27.971
After preservation, whereas a lot of other green leafy, they lose their color and they fade out.
00:12:28.292 --> 00:12:31.471
So that's why I push alfalfa meal.
00:12:31.942 --> 00:12:35.351
It helps me get that extra vitamin A that I'm looking for.
00:12:36.152 --> 00:12:40.971
It's funny, you were talking about that just about the time that Rob Guerin's comment came on.
00:12:41.466 --> 00:12:48.197
And he said, I had someone tell me that if the feather isn't getting clean of the sheathing to feed more greens, could that be vitamin A?
00:12:48.996 --> 00:12:50.167
That's exactly what it is.
00:12:50.206 --> 00:12:57.287
But look, most of your off the shelf layer feeds are going to run 3, 000 to 3, 500 on vitamin A.
00:12:57.787 --> 00:12:58.866
Vitamins are expensive.
00:12:59.297 --> 00:13:05.437
Vitamin A right now to somebody like me, who's a vitamin blender, making products.
00:13:05.437 --> 00:13:13.096
I haven't, I didn't look at the price list at the beginning of the month, but I think the last time I looked at it, it was like 8 and something a pound.
00:13:13.236 --> 00:13:14.057
So it's not cheap.
00:13:14.496 --> 00:13:28.846
It's not horrible expensive, until, man, I hate to even say this, but until like combat come out on the market and started pushing higher numbers The commercial feed industry's been on a race to the bottom, Frank, to who can make the cheapest feed.
00:13:29.496 --> 00:13:34.226
And and that's because the consumer goes in there trying to save a dollar on a bag of feed.
00:13:34.626 --> 00:13:37.736
You can save your dollar, but you're going to spend it somewhere else.
00:13:37.927 --> 00:13:39.187
You're just going to feed more feed.
00:13:39.692 --> 00:13:47.491
That's like I had somebody contact me today and said he was having a hard time finding a quality feed that was economical.
00:13:48.152 --> 00:13:51.142
And I said I hate to break the news to you, but you're not going to.
00:13:51.942 --> 00:13:52.422
Yes.
00:13:52.731 --> 00:13:54.211
Those two don't come together, right?
00:13:54.282 --> 00:13:55.052
No, not at all.
00:13:55.476 --> 00:14:05.567
Yeah, I, and we see those posts on the, on Poultry Keeper 360 or poultry breed or nutrition, or I wanna find a good feed that doesn't break the bank or is economical can't wait.
00:14:05.657 --> 00:14:08.346
This is what don't they call that an oxymoron?
00:14:08.346 --> 00:14:09.216
You can't have both, right?
00:14:09.366 --> 00:14:09.456
Yes.
00:14:09.956 --> 00:14:10.557
One or the other.
00:14:11.006 --> 00:14:12.106
So, like
00:14:12.226 --> 00:14:13.101
trying to heavy cake and
00:14:13.182 --> 00:14:13.581
eat it too.
00:14:14.381 --> 00:14:19.032
You're not gonna go, you're not gonna go to a steakhouse and get a filet mignon for five bucks.
00:14:19.831 --> 00:14:20.741
It's probably a good thing.
00:14:20.761 --> 00:14:22.451
I'd spend a lot of money,
00:14:22.942 --> 00:14:23.971
Here's the challenge, right?
00:14:24.022 --> 00:14:41.371
If you ripped on it now, Carrie did it before, when you break out of the mold of buying, locally available common feed, and you actually step up to the plate and you try something that is properly formulated for breeding fowl.
00:14:42.172 --> 00:14:43.451
It is night and day.
00:14:43.562 --> 00:14:44.682
You give it 30 days.
00:14:44.682 --> 00:14:44.846
It's
00:14:44.846 --> 00:14:46.239
a huge eye opener.
00:14:47.038 --> 00:14:50.323
When you're feeding 25 percent less and your birds look better.
00:14:50.913 --> 00:14:54.844
It is day and night and I'm not just trying to sell you something.
00:14:55.014 --> 00:14:55.083
I'm
00:14:55.083 --> 00:14:56.024
not, I'm not,
00:14:56.823 --> 00:14:57.153
you
00:14:57.153 --> 00:14:58.303
don't even sell feed.
00:14:58.984 --> 00:15:06.823
I don't sell feed, but every time I have to recommend all flock or flock grazer or whatever, it's still drives me nuts.
00:15:06.833 --> 00:15:09.964
Cause I know it's not as good as it could be.
00:15:10.384 --> 00:15:10.803
Yeah.
00:15:11.433 --> 00:15:17.793
It's better than some of the other stuff on the shelf, but that doesn't mean that it's great.
00:15:18.594 --> 00:15:19.134
Exactly.
00:15:19.933 --> 00:15:24.884
Like earlier, you were talking about vitamin A levels being in the three thousands.
00:15:25.543 --> 00:15:27.734
Ideally, they would be over double that.
00:15:28.533 --> 00:15:29.683
In an ideal world, they
00:15:29.683 --> 00:15:34.014
would be closer to 7, 000 to 7, 500 IUs a pound, right?
00:15:34.053 --> 00:15:34.224
Yeah.
00:15:34.494 --> 00:15:44.874
Yeah, when I'm doing breeder feeds for you or Rip or, when I'm doing breeder feeds for people who really, want to do it right, I'm at minimum 6, 500, right?
00:15:45.024 --> 00:15:53.293
Bottom, my bottom line is 6, 500 and a lot of them I'm cranking out at 7, 500 or 8, 000, right?
00:15:53.374 --> 00:15:56.644
Because I know what that's going to do for the chick figure.
00:15:57.384 --> 00:15:57.724
Okay.
00:15:58.288 --> 00:16:03.519
I know what head start that's going to give the chick the day it comes out of the shell.
00:16:03.969 --> 00:16:09.438
And if we're breeders and we're worried about the next generation, that's where we got to spend the money.
00:16:09.899 --> 00:16:15.678
30 days prior to harvesting eggs till, until you're done, at least.
00:16:16.479 --> 00:16:17.839
Something, step it up.
00:16:18.639 --> 00:16:20.778
It makes a huge difference, a
00:16:20.778 --> 00:16:21.578
huge difference.
00:16:22.379 --> 00:16:31.589
I had somebody asked that question today and they were like, Hey, we want to start hatching eggs, putting eggs in the incubator around the 1st of February.
00:16:32.078 --> 00:16:38.318
How soon should we be feeding either your feed or breeder supplement in with our feed?
00:16:38.318 --> 00:16:41.219
And I said, Christmas time would have been the best.
00:16:42.019 --> 00:16:42.558
Yeah, exactly.
00:16:42.889 --> 00:16:44.948
And he said, really?
00:16:45.099 --> 00:16:46.308
And I said think about it.
00:16:46.859 --> 00:16:56.499
Anytime you start taking extra vitamins and minerals and supplements yourself, it takes time for that to get into your system and make changes.
00:16:57.298 --> 00:16:58.538
A chicken is no different.
00:16:58.538 --> 00:17:00.739
It takes time for that stuff to get in their system.
00:17:01.418 --> 00:17:03.009
and do what it's supposed to do.
00:17:03.808 --> 00:17:05.939
And he said I guess we're way behind.
00:17:06.739 --> 00:17:09.858
I said, what you can do is get a really good start on next breeding season.
00:17:10.659 --> 00:17:10.999
Yes.
00:17:11.798 --> 00:17:15.909
And honestly, I got started on Jeff's recommendations.
00:17:16.709 --> 00:17:18.618
After I already had a bunch of birds hatched out.
00:17:19.078 --> 00:17:22.239
Okay, and I saw a lot of improvement.
00:17:22.249 --> 00:17:27.219
Don't get me wrong, but where I saw the most improvement was the following hatching season.
00:17:28.019 --> 00:17:28.318
Yeah,
00:17:29.118 --> 00:17:31.138
you can't really do it intermittently.
00:17:31.148 --> 00:17:32.108
You can't, right?
00:17:32.229 --> 00:17:35.078
If you only want to feed for the breeding season, fine.
00:17:35.568 --> 00:17:41.189
You're going to see improvements, but if you feed them at that higher level.
00:17:41.713 --> 00:17:42.604
all year.
00:17:43.243 --> 00:17:45.844
You're going to go even to another level, right?
00:17:45.973 --> 00:17:48.534
You're just going to go to exactly a completely different level.
00:17:48.594 --> 00:17:49.453
Exactly right.
00:17:50.253 --> 00:17:57.054
Because the parent stock, both, the hand and the rooster have been fed right all year.
00:17:57.054 --> 00:18:09.433
So all their tissues, all their body functions, all their glandular work, everything is optimized, right there and it's peaking and that's all going to transfer to that chick.
00:18:09.483 --> 00:18:11.574
While the rooster has a small contribution.
00:18:12.193 --> 00:18:16.663
But, that hen, that yolk, that quality of the protein and the whites, a lot of it, a
00:18:16.973 --> 00:18:17.844
lot of it's there.
00:18:17.844 --> 00:18:18.213
Yeah,
00:18:18.394 --> 00:18:20.263
it's, yeah, it's there.
00:18:21.064 --> 00:18:22.324
What about vitamin E?
00:18:22.334 --> 00:18:31.733
Now that I know acts as an antioxidant protects the cells from damage supports immune function, but what are some optimum levels?
00:18:32.239 --> 00:18:33.449
that we should be looking for.
00:00:05.030 --> 00:00:08.250
00:00:08.740 --> 00:00:17.260
00:00:17.730 --> 00:00:18.719
00:00:19.143 --> 00:00:19.164
Yeah.
00:00:19.164 --> 00:00:20.743
Yeah.
00:00:29.141 --> 00:00:35.591
00:00:35.671 --> 00:00:40.101
00:00:40.902 --> 00:00:48.512
00:00:49.311 --> 00:00:51.542
00:00:51.601 --> 00:00:52.381
00:00:52.652 --> 00:00:57.792
00:00:57.862 --> 00:01:04.751
00:01:05.302 --> 00:01:08.421
00:01:08.632 --> 00:01:20.921
00:01:21.552 --> 00:01:24.341
00:01:24.837 --> 00:01:29.947
00:01:30.016 --> 00:01:33.927
00:01:34.356 --> 00:01:36.936
00:01:37.436 --> 00:01:41.897
00:01:42.447 --> 00:01:52.966
00:01:53.387 --> 00:02:02.576
00:02:02.966 --> 00:02:10.586
00:02:10.796 --> 00:02:17.766
00:02:18.266 --> 00:02:19.266
00:02:20.067 --> 00:02:21.497
00:02:21.977 --> 00:02:31.437
00:02:32.236 --> 00:02:34.516
00:02:34.556 --> 00:02:41.776
00:02:42.407 --> 00:02:50.206
00:02:50.276 --> 00:02:52.616
00:02:53.192 --> 00:03:17.891
00:03:18.472 --> 00:03:18.491
00:03:19.097 --> 00:03:22.757
00:03:23.206 --> 00:03:31.616
00:03:32.236 --> 00:03:37.086
00:03:37.146 --> 00:03:45.937
00:03:46.271 --> 00:03:47.872
00:03:48.252 --> 00:03:51.972
00:03:51.991 --> 00:03:55.282
00:03:55.831 --> 00:03:57.771
00:03:58.181 --> 00:04:04.042
00:04:04.472 --> 00:04:05.842
00:04:06.211 --> 00:04:06.722
three, four
00:04:06.722 --> 00:04:10.331
00:04:10.331 --> 00:04:11.241
00:04:11.331 --> 00:04:11.641
00:04:12.442 --> 00:04:27.521
00:04:27.581 --> 00:04:29.932
00:04:30.507 --> 00:04:33.997
00:04:33.997 --> 00:04:41.336
00:04:42.137 --> 00:04:54.177
00:04:54.257 --> 00:04:54.526
00:04:54.526 --> 00:04:57.976
00:04:58.586 --> 00:05:04.076
00:05:04.846 --> 00:05:07.826
00:05:07.836 --> 00:05:18.637
00:05:18.666 --> 00:05:19.916
00:05:20.357 --> 00:05:27.516
00:05:28.317 --> 00:05:34.857
00:05:35.211 --> 00:05:41.591
00:05:42.141 --> 00:05:48.922
00:05:49.302 --> 00:05:50.802

00:05:53.762 --> 00:05:57.541
00:05:57.541 --> 00:06:01.502
00:06:01.531 --> 00:06:10.831
00:06:10.872 --> 00:06:12.122
00:06:12.141 --> 00:06:13.461
00:06:13.822 --> 00:06:16.031
00:06:16.581 --> 00:06:22.841
00:06:22.882 --> 00:06:25.721
00:06:26.172 --> 00:06:31.841
00:06:32.232 --> 00:06:37.211
00:06:37.851 --> 00:06:41.341
00:06:41.612 --> 00:06:42.021
00:06:42.122 --> 00:06:43.211
00:06:43.461 --> 00:06:44.732

00:08:04.331 --> 00:08:04.901
00:08:04.971 --> 00:08:08.312
