Vitamin B6 is a general term for pyridoxol, pyridoxal, and pyridoxamine, which have the same biological effects in animals.
Vitamin B6 is an important component of many amino acid decarboxylase, transaminase, etc. Enzymes containing vitamin B6 are involved in the synthesis and catabolism of almost all amino acids, and are also important for the metabolism of fats, sugars, and inorganic salts. When lacking vitamin B6, young animals grow slowly or stop. Animals such as pigs, dogs, and monkeys experience severe anemia caused by insufficient red blood cells and hemoglobin, resulting in poor growth. The disorder of glutamate metabolism in the body causes the accumulation of glutamate in the brain, stimulates the cerebral cortex, causes local epileptic foci, and causes epileptic seizures in animals.
When chickens lack vitamin B6, their excitability is strong, they have symptoms of playing games, their legs are weak, dermatitis, hair loss, hair loss, and bleeding. The mortality rate increases, while the egg laying rate and hatching rate decrease. Recent studies have shown that when vitamin B6 is lacking, the titer of animal antibodies is low and increases after supplementation.
Natural feed is rich in vitamin content, while Yeast, grains, legumes, seed husks, and grasses are relatively abundant. Animal Feed and tubers are relatively rare. The naturally occurring vitamin B6 is easily utilized by animals, and generally pigs are not susceptible to deficiency, while chicks are prone to developing deficiency. When the protein and energy content in feed is high, the demand for vitamin B6 increases. The demand for vitamin B6 increases in young animals, pregnant females, and when taking certain sulfonamide drugs and antibiotics. Increasing the amount of vitamin B6 added to the diet can enhance animal immunity and anti stress ability. Adult ruminants generally do not require supplementation
Vitamin B6 is an essential additive in aquatic feed. Vitamin B in feed is often added in the form of pyridoxine hydrochloride Pyridoxine hydrochloride is easily soluble in water and resistant to high temperatures in acidic and alkaline solutions, but it is easily damaged when exposed to visible light
Vitamin B has the following main effects in aquatic animals:
1) Affects protein and amino acid metabolism, improves feed nutrient utilization, and promotes growth.
2) Affects fat and sugar metabolism, promotes lipid metabolism and transport in fish serum, thereby avoiding lipid accumulation and the occurrence of nutritional fatty liver disease in fish
3) Affect the body composition of aquatic animals, promote the accumulation of vitamin B itself in the body, increase the content of unsaturated fatty acids, and improve the nutritional value and flavor of aquatic products. Adding vitamins to feed
B can promote the synthesis of body proteins and accelerate the generation of amino acids Moderate addition of vitamin B can increase the content of highly unsaturated fatty acids in tissues and the activity of trypsin like enzymes in shrimp liver and pancreas Vitamin B6 can significantly reduce serum triglycerides, total cholesterol, and glucose levels, and correspondingly increase serum high-density lipoprotein, cholesterol, and albumin levels, as well as amylase activity
