Does anyone know what research?

I have not used thymol or C vitamin n wintering syrup. They are not needed.

Not needed if your annual losses are zero. For mere mortals it's a 33% reduction in winter losses and stronger healthier colonies in spring by adding vit. C
As for thymol , I guess your bees have no nosema either.
Cheap and simple ways of improving the condition of your colonies.
Why wouldn't you ?

Hi SDM,

On adding Vitamin C, I wondered if there is a standard recommendation as to quantity that should be added to the syrup please?

 

[Walrus]

The research paper says 1.8 mg per 1 kg syrup

 

[SDM]

I use a far higher dose of 1g per litre. I'll check tomorrow( I've forgotten what readings I got, ) what that does to the syrups ph, as it would be ideal to match ph with honey( I reckon that must be pretty close since it's what I stuck with), this being good for gut microbiome.

.in Finland we do not use C ,vitamin in winter syrup.
Never heard.

Walrus pop a link to the paper pls. Ian

I guess you don't use vit. C in Finland for spring feeding either. Which given the extremes you go to to promote brood rearing, seems bizarre.

There are several, the one I linked above for Finman uses up to 6g/ litre of 1:1 syrup
I think that's the highest I've seen used.

 

[For want of a better word]

Pollen subs/bee bread formula for spring feed contains Vit C

1/3 soya flour Hi Pro Mole Valley 25kg bag
1/3 Cows milk powder Mole Valley 20kg
Brewers yeast 10kg
Cider vinegar

Rapeseed oil 10 - 15 tablespoons per 15lbs
Vitamin c powder ... 2 teaspoons per 15lbs
add to 2;1 sugar syrup + couple of drops of lemon grass oil..
wrap in clingfilm and refrigerate until needed

perhaps more vitamin C could be added

Not read of adding to the winter sugar.... may trial it!

The 2 studies I linked in post 12 should be good enough reason for everyone to add it

C vitamin does not help, if bees do not get pollen from nature.

But it does help if they do. Which they do.

Well, intetesting research..

In nutrition writings it is said that bees need vitamins. But it is never said, what vitamins and how much.

From content of royal jelly I can see that B Vitamins are very important. There is quite little C vitamin in royal jelly.

I do my own pollen patty. I put there,C.vitamin, multi B vitamin and usual multivitamin pills and magnesium.

I do not have succeeded to feed bees with patty, if it does not have 20% irradiated pollen

 

[Antipodes]

Thanks guys for the follow ups on the Vitamin C amount.

 

[Finman]

In natural honey C vitamin content varies by plants. Mostly it is 1.4 - 2.8 mg/ 100 g.

Well, that 1.8 g/ syrup litre is quite natural..

True but vitC still has benefits for royal jelly production as bees raised on supplemented vit C diets have more hypopharyngeal acini ( by about 15% I think) which results in them raising more brood.

Of course all essential nutrients are important. But you cannot add brooding with C vitamin. As Well you cannot add brooding with sugar.

When the colony gets pollen from nature, then the limiting factor is bad cold weathers, and how BIG cluster they have, when they keep warm brood area.

For example, when I feed patty to the colony, and weathers are bad, bees drop brood rearing 50% quite quickly and they put save mode on. When sun starts to shine, the queen add quickly laying to such maximum, what bees can maintain in the hive.

With electrict heating and with patty feeding I have got 3 fold speed in spring build up in big hives. Small colonies cannot build up fast because they are small.

At same time (3 weeks) when a BIG colony rear 10 - 15 frames brood, a small colony rear 1-3 frames.

Yeah. I have done very long time this work, and I know what they can do.

I have allways given C vitamin into the patty.

I do not believe that. There are many other limits in brood rearing than C-vitamin.
If they get enough C vitamin, they do not need it more.

That experiment makes no Sense. .Guys are not very skillfull.
Skimmed milk has 50% lactose, which bees cannot use. Why did they did that study.
Bees do not eate mere soya flour. I know that.

. But I have studied biology in Helsinki University and I have read all tesearch from Internet what I have fine about nutrition of bees.
To pick one element from the whole, and there it is! It does not go that way.

A norman beekeeper does not even know what is aminoacids or what is sugar.

You have jammed now to C vitamin. Try to get over it.
