Niacin Overdose

[Isaac 0]

Just to show how easy it is to overdose, by my math 3 drops of b complex would be an overdose for a 35g duckling (day old mallard size)

Also if you put one ml in a water dish and you had 4 ducklings, if they drank half the water (obviously spilling the other half) that would also be an overdose.

Interesting that this is in stories guide, maybe its not full of typos just information that is not commonplace?

Not sure I understand what you're trying to say...

Yeah but cyanocobalamin is in durvet b complex, you recommend that all the time.

The study shown above states that it takes several hundred times the recommended dose for there to be any possible side effect, it seems pretty safe to me. Hundreds of people have treated their ducks using Cattle B Complex Brands and to my knowledge, there haven't been any toxic side effects reported yet.

Yes, it appears that giving too much niacin can have the opposite effect.

"Clinical signs for niacin toxicosis in chicks include reduced egg production, growth retardation, short legs and coarse, dense feathering. High dietary levels of niacin (0.75% to 2.0%) fed to broilers were detrimental to dimensions and mechanical properties of bone (Johnson et al., 1992; 1995; Leeson and Summers, 2001). There was no change in the mineral content of the tibia, but bone strength decreased with increased susceptibility to fracture.”"

Interesting isn't it?

Yes, thanks.

Yes, I got the label. Do you have the brand name?

Oh sorry it’s bulk powders https://www.bulk.com/uk/b-vitamin-complex-tablets.html

Let me see if I can find a better one for you. It's pretty low in thiamine which is the vitamin were trying to rule out here. We want about 5mg thiamine per tablet, this one only has 1.1mg.

Is it also important to consider how much they are drinking and eating at the same time that you are dosing Issac ?

For example, with our very poorly ducklings, they were barely drinking or eating (supplemented with BY) at all - the dose in the water was quite high but their intake of anything was very low indeed. I also made sure they at least had a nibble of something at the same time as having their bill dipped. We tried dropper feeding before and I suspect that contributed to one of our poorly ducklings dying.

My reasoning was I know if I take supplements on an empty stomach, I can end up feeling queasy.

Once they started more normal ducky behvaiours with their food and water (standing in it, throwing it everywhere) I tapered down the dose because I read that as a sign they were recovering and eating and drinking more.

Thank you for the info - I think its super important to understand as much as possible on the dosing and quality of supplements.

We don't know exactly - we do know the new breeding pair (Cayuga) had a very high fail rate with successfully hatching and then surviving beyond the hatch (either that or Mr Buff our Don Juan of the boys has awesome super genetics which meant every hatchling survived last year).

We won't be breeding from either of them moving forward or their offspring.

Where the eggs were from the breeding pair, I think we had one out of seven survive, with two dying post hatch. Where they were crossed with a KC or a Buffling, we had a better but still not great rate of something like one in two.

All I can say is that for the survivors, connected or otherwise, their symptoms were: poor overall development (they seemed premature even at 28 days+) lack of strentgh, poor co-ordination, bad positioning in the egg, trembling, poor appetite, splayed legs and one case of wry neck. Some were still absorbing as they came out the shell so had that additional challenge.

I've shared Wonkys story on the board - (s)he probably had most issues whilst managing to survive.

I supported Wonky with bill dunking (food and duck lucozade) for nearly two weeks.

This is my third time trying to post this (for some reason my replies keep on going to the wrong post) but here goes...just wanted to say thank you for posting this, very helpful and informative

I have a question about chicken niacin overdose. If you are feeding a mixed flock of chickens and ducks chicken layer pellets, and supplementing niacin in the water or feed, would the chickens be overdosed on niacin?

 

[Miss Lydia]

You just linked the thread we are already on, I read this and it’s about ducks, I’m asking about chickens when fed the correct duck amount

Well then the info is right here . Sorry I didn't look closely at the heading.
I have raised many chickens and ducklings not in the same brooder but on the ground after mama takes them out and they all are fed extra niacin in the form of Nutritional yeast I haven't ever used just plain niacin on any of my flock other than Liquid B Complex if I notice a ducking with shakey legs. As far as I can tell none have suffered any health issues many of my chickens live to be 8-13 yrs old. Ducks too.
