Ok, thank you so much! I will try this tomorrow. How long do you think it will take before he shows improvement?
We recommend for novice duck keepers to give them the complex over treats, to reduce the risk of aspiration if given orally with a syringe. Duck seems to enjoy mealworms, peas, lettuce, tomatoes the most, it can also be mixed into a wet soupy feed. The reason we recommend not giving it in water is most of the time ducks spill around half of the water, so it makes it hard to calculate the dosage, and birds that are in poor condition may not be able to get around to drink often. If your duck is not able to get around or is so debilitated, you may need to administer orally with a syringe/eyedropper, the easiest and safest way I have found is to drop the B complex onto the side of their bill, the sensation of the water droplets often will make them drink the liquid, another technique is to dip their bill for a short second in some of the liquid. If this doesn't work you may need to stick the syringe in their mouth, I will provide an article on the bottom on how to do that correctly.
I can not stress enough how important it is to be very careful when giving birds fluids orally, they can easily die of aspiration, especially ducklings that are on the younger side. Always be gentle with the bird, avoid putting pressure on their crop, and give them plenty of short breaks during the administration so they can get everything down.
The dosage
The dosage will vary accordingly to age, currently, we go:
- 1/4ml, once a day, for ducklings 1-7 days old
- 1/2ml, once a day, for ducklings 7-14 days old
- 1.0ml, once a day for duck(lings) older than 14 day
This is once a day, although if you have a hard time getting the complex into the duckling you can split the dosage in half and give some in the morning and evening. This seems to work well with ducklings that are disgusted by the taste of the complex.
Possible overdose
The effects of giving to much niacin are somewhat limited, it does seem, however, that you would need to give a large amount to the duck for it to have a damaging effect
This is a quote from John Metzer:
"We have been asked if it is possible to overdose on niacin. Because of how small the amount is, it is easy to think you can give your birds too much. The answer is that you would need a lot to overdose. We don't have an exact amount to point towards, but humans can overdose on niacin and that can cause bowel problems. If your birds start having digestive issues, then it's a possibility, but is unlikely."
Note that this is referring to niacin only, there are other ingredients in B complex that should be used more carefully like thiamine(B1).
The duration
Treatment should still proceed daily for a few weeks even after the birds aren't showing symptoms anymore, it would, however, be wise to keep them on Nutritional Yeast or niacin supplement until they are of eight/ten weeks of age or older, simply sprinkle one to two tablespoons over one cup of their feed.
Recovery time
Recovery time will vary with each individual, generally the younger the bird is the quicker the recovery time. With young ducklings, complete recovery can be seen within hours or days, with older birds a few weeks is common.
How to keep your duck comfortable while recovering
It’s important during treatment for the birds to have soft clean bedding, and offered food/water often. Pain and discomfort in the legs of niacin deficient birds is quite common so letting them exercise and relive the weight off their legs may help significantly during treatment.
Birds that tend sit around most of the day aren't able to able to practice hygiene and are going to be more likely to end up with other problems like
wet feather,
bumblefoot,
sticky eye, or
external parasites, letting them in the water may help to prevent most of these problems for occurring. When doing water therapy, given that the duck's leg is most likely weak, they should be watched the whole time they are in the water to ensure they don't drown.
Prevention:
Prevention is key to keep these problems from occurring, we have noticed that problems most commonly arise when the owner mistakingly thinks that ducks have the same niacin dietary needs as chick's, as cited in "Holdrreads Storey Guide" growing ducks require two to three times more niacin then growing chicks, too often ducklings are fed chicks starters low in niacin, and that is when problems most often occur. Sadly, with heavyweight breeds like Pekins feeding them duck starter is still not enough, most duck starters contain 55mg of niacin per kilo of feed, and while that reaches the niacin requirement for most other medium to smaller wight breeds, Pekins and other heavyweight breeds should have at least 70mg of niacin per kilo, to achieve that goal, in addition to the duck starter/all poultry feed, a niacin supplement such as brewer's yeast, nutritional yeast, B complex, or a poultry vitamin should be added to their diet until at least ten weeks of age when the niacin content drops. For nutritional yeast, simply add one to two tablespoons per cup of feed, if the yeast has added garlic flavoring you may consider only one tablespoon per cup of feed as the taste may be too strong for ducks. Liquid B complex can be added over treats and feed as a preventative too, a few drops over feed/treats is usually sufficient. B complex tablets can also be used, one 500mg tablet can be added to eight/ten gallons of drinking water.
