Welcome to today's article on Nutritional Deficiencies in ducks. There's a quick pinpoint to diagnosing and treating ducks and you can read through this to find out what causes it. This article will also discuss simple physical therapy routines to help rebuild a duck's muscle tone. There's also going to be a small discussion on what to do if lameness doesn't go away and ducks remain unable to walk.
Nutritional deficiencies are directly caused by a lack of Niacin and B Complex, Niacin is one of the main B vitamins, being Vitamin B3. A deficiency in these nutrients can cause lameness and inability to walk, and sometimes a low energy level. The appearance of this is similar to that of chicks with spraddled legs except a leg band will not directly help the issue. One or both legs may be unable to function normally, as well as swelling of their legs, or bowing is a common thing to see with deficiencies.
Ducks, and other waterfowl, can quickly become deficient in these nutrients due to poor quality commercial feeds available for ducklings and young adults. B vitamins are vital for healthy bone and muscle development. When you get feed for your ducklings, you may want to ensure the chick starter is directed towards a duck's needs, or ensure the diet is high in Niacin. If not you can find some great ways at treating and supplementing Niacin and the rest of the b vitamins. When ducklings are 6-12 weeks old is around the time a deficiency will begin to happen, ensuring you provide the right diet will help prevent it from happening or worsening. Here's how to treat nutritional deficiencies!
There's a few different options and tips you can use to your advantage. The first option is sprinkling Brewers Dried Yeast, aka nutritional yeast in their food and water. This will provide a lot of the nutrients they need but may not have the perfect amount that can be a replacement to a fortified duckling diet or even supplementing vitamin pills. For providing supplements by giving them vitamin pills, you'll want to go to your local store that sells a dry capsule or a compressed pill of Niacin, or B-Complex. Mostly you only need Niacin, but I prefer some of both to ensure all B vitamins are being covered.
Dosages for Niacin and B complex. Recommend getting a MG scale, one that can be used for weighing medication, you may also need a pill crusher or a couple spoons. Crushing the pills with spoons is easy, place the pill on a spoon, put another spoon on top and press firmly until the pill is soft crushed and mostly powdery. Supplementing several ducks, using 100 Mg of both, per gallon of water, for supplementing one duck you'll want to provide 10 MG of Niacin per duck weighing 3-5 Lbs. For ducks less than 3lbs, start off with 5 MG per duck. As far as giving them the vitamin dosage, dilute it in water to add to chick mash. Avoid syringe feeding unless well educated on the process to prevent aspirating.
Preventing Lameness from nutritional deficiency is easy by starting early intervention, when you buy ducklings, purchase a food made for ducklings to consume. If there are no feeds directed for ducklings, get a chick starter, and Niacin, dose out vitamins as recommended. When ducks are adults you can either still provide this well into adulthood, or begin to use a diet fortified for ducks and geese. You can also feed veggies known for these vitamins like kale to your ducks to ensure they get the nutrients they need. If you've already experienced ducks with a deficiency, it's important to follow the treatment steps above if you are currently dealing with it or are seeing this after you brought home ducklings. Keeping them healthy is important to ensure they live a long happy life.
Physical therapy for ducks is quite easy to start, for adults and ducklings you may offer them a pool of water just to keep enough for them to float and have their feet touch the bottom. They will push their feet across and allow them to swim several times a day. Offering their favorite foods like mealworms or peas is a great encouragement to help them move around. In addition to the water therapy, you can also take their legs and try to get them to straighten out and step on their feet or make a makeshift wheelchair where their feet can also touch ground on a solid floor to try walking. Therapy takes lots of intense time and care, but is possible to manage if you're early enough in treatment.
For long term care there's a few things to consider, nutrition wise, they will still need to remain on a good nutritionally balanced feed, plus supplementing small dosages of the vitamins. They may require a hand made wheelchair. You can still let them live a happy normal life as outside ducks, they will need pool ramps both in and out, low water dishes, and ramps into the coop. Sometimes they may develop decent wing muscles to flap around as their mobility method.
Ducks with lameness may not live nearly as long as regular healthy ducks. It really depends on their will to live and how healthy they are. Sometimes if too late to provide appropriate nutrients ducks may also pass away as well. All waterfowl require Niacin and B-Complex as vital nutrients to develop healthy bones and muscles. They also need to be fed carefully especially for heavier breeds. Fast growth in ducks is not really great on their fragile legs.
