Before 1937, brewer’s yeast (natural product that contains almost all vitamins of group B) was given daily to the Swiss army soldiers “for the good results achieved in times of maneuvers.”
Must be combined with calcium to enhance absorption by the organisms.
Vitamin B12 is accumulated primarily in the liver. Animals and plants are unable to make it. Só1o is synthesized by anaerobic bacteria and yeasts. (more…)
The excess vitamins poisoning is rare when you use food as their source. But given the disproportionate use of synthetic vitamins is that they are currently be found poisoned birds. So then describe the symptoms that come and the necessary amounts of each vitamin to produce alterations:
- Vitamin A (20 to 100 times the dose required)
The symptoms are: weight loss, decreased appetite, swollen eyelids and mouth, decreased bone strength, dermatitis, liver abnormalities, and bleeding.
- Vitamin D (From 4 to 10 times the dose required)
Its excess leads to increased calcium absorption, resulting in hypercalcemia and soft tissue mineralization. Excess blood calcium in kidney impairment originated by accumulation of this mineral in them. (more…)
Vitamin K was discovered in Denmark as a nutritional factor necessary for blood coagulation in chickens that were being fed a diet devoid of fat that made them bleeding. In administering certain foods, especially alfalfa and putrefied fish meal, was that such alteration was corrected.
Vitamin K is stable and resistant to heat, therefore not destroyed by ordinary cooking methods.
It can occur in three ways:
- K1: present in green plants.
- K2: produced by microorganisms of the intestinal flora.
- K3: synthetic nature. (more…)
It was discovered by Evans and Bishop in 1922 to observe that rats fed with cow’s milk did not reproduce. Its most important chemical cha
racteristic is its antioxidant property. He has close relations with the metabolism of selenium. It is stored mainly in adipose tissue and liver. Storage in the body is in a relatively short time.
Sources:
It occurs mainly in the oil extracted from wheat germ and oils extracted from seeds or other oleaginous fruit (corn, sunflower, peanuts, soybeans, walnuts, olive oil), egg yolk, brown rice, fresh peas, green beans, tomatoes, celery, apples, bananas, etc.. Alfalfa leaves are rich in vitamin E. (more…)
Since the Middle Ages has been used cod liver oil as a remedy for rickets, but only until the First World War must be the cause of the disease and provided the scientific basis for its cure. There are two predominant forms of vitamin D:
Ergocalciferol (Vitamin D2) derived from plants and cholecalciferol (vitamin D3) produced exclusively in the body of a bird
In all birds studied, vitamin D3 is 30 to 40 times more potent than vitamin D2.
Unlike other vitamins, vitamin D3 can be synthesized in the body skin level. Studies showed that chickens could synthesize enough vitamin to prevent rickets and maximize growth when young chicks were exposed to direct sunlight (not filtered through glass) during a time of 11 to 45 minutes each day.

It was the first fat-soluble vitamin discovered. Two groups of researchers made the discovery almost simultaneously in 1913. They found that young animals fed diets without natural fats showed general disorders and did not grow. They also observed that showed inflammation and infection of the eyes, symptoms that could be quickly alleviated by adding natural fat diet, butter or cod liver oil.
Plants do not contain vitamin A in active form, but in the form of precursors thereof as carotenoids (yellow pigments found associated with the chlorophyll and responsible highly colored red and yellow legume): alpha, beta and gamma. In birds the beta-carotene is the most active of all.
The carotenes are considered pro-vitamins. Animals can not synthesize, but it may take to form. active (vitamin A) in the intestine and liver. Approximately 90% of vitamin A in the body is stored in the liver. These reserves can be exploited in any state of emergency, when through the diet does not bring enough. (more…)
All poultry have heard of vitamins and their importance to the organism of animals. Reason why it is such a rare bird lover who does not use vitamin supplements.
Vitamins are natural components of food, being present in tiny amounts. Its nature is organic and are essential for normal growth and functioning of different organs. They are generally manufactured by the body in sufficient quantities to meet the physiological requirements and therefore must be obtained through diet.
VITAMINS “natural or synthetic?
Natural vitamins are those that are present in foods naturally. While synthetics are man-made in a laboratory and made available to the public in the form of drops, powders, tablets, capsules, etc.. (more…)
