Pantothenic acid (vitamin B3) is a component of coenzyme A, and coenzyme A in many biochemical processes play an important role, and carbohydrate, fat and protein metabolism.
Pantothenic acid deficiency symptoms: the performance of health good chicken blocked, feathers rough, stout bone disease, followed by dermatitis, the limitations of mouth crazy plots damage; eyelid edge grainy crust blocks, often mucus stalemate, cloaca and toes appear so crazy skin difficulty in walking. Hepar thymus atrophy, muscle gastric mucosa by corrosion, gallbladder enlargement. Hen hatching eggs produced, the embryo more than two or three days in the incubator on the last death, but no lesions.
Symptoms not severe, change feeding or oral diet rich in pantothenic acid of 10 to 20 mg calcium pantothenate can be fully restored. Pantothenic acid widespread in mammals, plant feed, hence the name. But in yeast, green feed, rice bran, bran, peanut cake is the most abundant. Valley real class feed all contain a certain amount, while the maize was the lowest.
Folic acid (vitamin wind vitamins to combat pernicious anemia. It is involved in the synthesis of methyl, methylation of hemoglobin synthesis required the participation of the absence of folic acid, will produce hematopoietic muscle energy barriers to malignant anemia. Folate and vitamin B12 nuclear protein deficiency can cause metabolic disorders in which nutritional anemia.
Folic acid deficiency symptoms: poor chick growth, abnormal feathers, short and thick anemia and bone disease. Eggs produced by hens in the incubation, the embryo mortality. Severe anemia in chicks injected 100 micrograms of folic acid 50 1, return to normal within a week, oral somewhat weaker results. In the diet with appropriate bean, yeast, alfalfa meal to prevent folic acid deficiency.
Leaves of plants, animals, organs and muscle, yeast, soybean, alfalfa meal, wheat bran is a rich source of folic acid. Seed, eggs with folic acid are also many. The relative lack of folic acid corn.
Niacin (nicotinic acid or vitamin PP) a more stable nature of begging can not easily be heat, oxygen, light and destroyed by alkali. It is the enzyme system involved in the body of a vitamin. Its body of carbohydrates, fat and protein metabolism play a major role, when the body can be caused when a lack of nicotinic acid metabolism disorder.
Nicotinic acid deficiency syndrome revenge as the performance loss of appetite, growth retardation, lack luster fluffy feathers, swollen hocks, bone short and thick, curved leg bones lying and manganese or choline deficiency is the difference between skeletal muscle disease stubby little health condylar bone from slipping.
Nicotinic acid content in the diet with more feed can prevent the occurrence of deficiency. The event of a suspicious lack of symptoms, the addition of nicotinic acid per kg feed, 10 mg, and soon bear fruit. But symptoms of bone short and thick, can hardly be effective.
Feed rice bran, wheat, barley, wheat bran, peanut cake, fish meal, yeast and green feed are a rich source of niacin.
