Vitamin A For Chickens

How to Give Vitamin A to Chickens

Vitamin A is essential for healthy vision, reproductive health, and immunity in chickens. It’s also needed for the production of healthy egg yolks and helps keep chickens’ skin and feathers healthy.

Chickens are unable to produce vitamin A on their own, so you’ll need to provide it through their diet. You can purchase a commercial vitamin A supplement from your local feed store or online retailer. If you have a large flock or want more control over what goes into your birds’ diet, however, consider making your own supplement.

The vitamin A content of fresh vegetables can vary widely depending on where they’re grown and how long they’ve been stored before use. Vitamin A is not stable when exposed to heat or light, so make sure any vegetables you plan on feeding are as fresh as possible. If you’re concerned about spoilage or your chickens’ palates not being accustomed to certain vegetables, try starting with just one vegetable at a time until they get used to eating it regularly.

Vitamin A For Chickens

Vitamin A deficiency is most likely to occur in chickens receiving an improper diet, heavily parasitized, or who are suffering from conditions that interfere with normal digestion. Also, vitamin A requirements are higher for chickens under stressful conditions such as abnormal temperatures or exposure to disease conditions. Chickens with vitamin A deficiency have an increased risk of getting sick. The two main mechanisms involved in the prevention of disease are the effect of vitamin A on the immune system and on epithelial integrity. Vitamin A deficiency also impairs regeneration of normal mucosal epithelium damaged by infection or inflammation and thus can increase the severity of an infectious episode and/or prolong recovery from that episode. Vitamin A deficiency presents as a number of different clinical manifestations, ranging from xerophthalmia (dry eye), uropygial gland infection, impaired growth, and increased susceptibility to severe infection. It affects ocular tissue in two ways: by slowing the regeneration of the visual pigments following exposure to bright light and by disrupting epithelial integrity.

how often to give chickens vitamins

Nutritional deficiencies are a relatively rare problem for a flock of backyard chickens, ducks or other poultry. Of greater nutritional concern are the following five easily avoidable mistakes commonly made in feeding poultry.

1. Inadequate Water

The most important thing to remember about what to feed chickens is water, and water deprivation is a serious matter. Yet most of us don’t think much about water quality and availability unless a problem arises.

Deprivation can occur for a number of reasons. The need for water goes up for your backyard chickens when the weather warms, but if the amount of water you furnish remains the same, some birds may not get enough. Even when the amount of water is sufficient, if the water is too warm, your birds may not drink it. Putting out extra drinkers, keeping them in the shade, and frequently furnishing fresh, cool water solves this problem.

Water deprivation can also occur in winter when the water supply freezes. To solve this problem, a number of different water-warming devices are available from farm stores and online livestock suppliers. Another solution is to bring your birds warm (not steaming hot) water at least twice a day.

Unpalatable water can cause water deprivation by discouraging drinking. The best solution is to furnish your backyard chickens only water you would drink yourself.

2. Inappropriate Ration

One of the most common errors in feeding poultry is to use a ration that is inappropriate for the flocks’ species, stage of growth, or level of production. For instance, what do ducks eat? What do chickens eat? The nutritional needs of ducks differ from those of chickens. And the needs of baby birds of any species differ from those of laying hens, which differ again from the needs of a breeder flock.

Furnishing an appropriate ration is easy if you purchase ready-mixed feed from the farm store since most brands print essential information on the bag or on the label. If you choose to mix your own rations, you will need to thoroughly research your facts about chickens and your other poultry for the nutritional needs at each stage of their lives.

3. Old Or Stale Ration

From the moment a ration is mixed, it starts losing nutritional value through oxidation and other aging processes. Feed that sits around too long goes stale, loses nutrients, and becomes unpalatable. In a warm storage area, the process speeds up.

Ideally, any prepared feed should be used within about 4 weeks of being milled. Allowing a week or 2 for transport and storage at the farm store, buy only as much as you can use within a couple of weeks. During cold weather, you can stretch the storage time, as I often do during the months when winter storms threaten to make our rural roads impassable. Storing feed in a cool place, and in a closed container, slows the rate at which it gets stale.

If you mix your own rations, it’s good to know that a vitamin premix has a maximum shelf-life of about 6 months. Purchasing a premix in bulk is therefore not a money-saving option for a small flock of backyard chickens. Either purchase premix in quantities small enough to feed out without 6 months, or arrange to share with like-minded poultry keepers.

Feeding Backyard Chickens

4. Over Supplementation

Feeding poultry excessive amounts of supplements — such as vitamin/mineral supplements or electrolytes — can cause a serious nutritional imbalance. Some vitamins interact synergistically with each other or regulate the use of certain minerals. Some minerals require the presence of other minerals to be effective. On the other hand, an excess of some minerals can interfere with the absorption of other minerals, and an excess of some vitamins can interact detrimentally with minerals or may themselves be toxic.

So, instead of making backyard chickens healthier, the unnecessary use of packaged vitamin and mineral supplements or electrolytes can have opposite to the desired effect. Do not routinely give electrolytes to healthy poultry. And never use a supplement, including electrolytes, for more than 10 days (unless advised by a veterinarian).

Electrolytes and vitamin/mineral supplements can be helpful for boosting the level of nutrition in a breeder flock just prior to hatching season, especially when the birds don’t have access to fresh forage. And supplements can help reduce stress when offered to poultry for several days before and after a show. However, do not use any supplement during a show — the taste may cause a bird in unfamiliar surroundings to go off feed or water, increasing its stress level.

If you formulate your own rations, the best way to guard against vitamin and mineral deficiencies or excesses is to include a commercially prepared premix (such as Fertrell Nutri-Balancer). Premixes are available in both standard and organic poultry feed formulations. Since using too much is as detrimental as using too little, carefully follow the directions on the label to avoid overdosing your backyard chickens.

5. Too Many Treats

We all love to see our backyard chickens come running when we bring them treats. But overdoing treats falls under the category of “killing with kindness.”

The most commonly overdone treat is feeding too much scratch grain. Feeding a little scratch each morning to keep your backyard chickens friendly is fine. Feeding a little in the evening to encourage them to enter their coop so you can close them up for the night is fine. In cold weather, a little scratch at bedtime will help keep your birds warm on the roost overnight. But feeding a backyard flock scratch grains as their primary source of nutrients does not provide a balanced diet.

Similarly, most kitchen scraps are good for backyard poultry. The birds enjoy fresh produce, the scraps add variety to their diet, and scraps are a healthful source of nutrients. So, as with scratch, feel free to treat your birds to kitchen scraps, but only in moderation.

One of the common issues with regard to backyard flocks relates to poor or inadequate feeding programmes that can lead to vitamin and mineral deficiencies for the birds. Vitamins and minerals are very important components of a chickens diet and unless a formulated ration is feed, it is likely that deficiencies will occur.

Poultry require all known vitamins except C. Some vitamins are soluble in fats, while others are soluble in water. Some of the symptoms of a vitamin deficiency are as follows:

Fat Soluble Vitamins
Vitamin ADecreased egg production, weakness and lack of growth
Vitamin DThin shelled eggs, reduced egg production, retarded growth, rickets
Vitamin EEnlarged hocks, encephalomalacia (crazy chick disease)
Vitamin KProlonged blood clotting, intramuscular bleeding
Water Soluble Vitamins
Thiamine (B1)Loss of appetite and death
Riboflavin (B2)Curly-toe paralysis, poor growth and poor egg production
Pantothenic AcidDermatitis and lesions on mouth and feet
NiacinBowed legs, inflammation of tongue and mouth cavity
CholinePoor growth, fatty liver, decreased egg production
Vitamin B12Anaemia, poor growth, embryonic mortality
Folic AcidPoor growth, anaemia, poor feathering and egg production
BiotinDermatitis on feet and around eyes and beak

Minerals are also important to the health and well-being of poultry. The following are some of the important minerals and symptoms of mineral deficiencies:

Minerals
CalciumPoor egg shell quality and poor hatchability, rickets
PhosphorusRickets, poor egg shell quality and hatchability
MagnesiumSudden death
ManganesePerosis, poor hatchability
IronAnaemia
CopperAnaemia
IodineGoitre
ZincPoor feathering, short bones
CobaltSlow growth, mortality, reduced hatchability

As indicated above, vitamin and mineral deficiencies can produce numerous health problems for chickens including in some cases, death. Thus, to prevent nutritional deficiencies, or when deficiency symptoms are noted, feeding a balanced poultry diet with the required vitamins and minerals should be practised.
