Vitamins are divided into two categories: fat-soluble vitamins and water-soluble vitamins. The former includes vitamins A, D, E, and K. The latter includes B vitamins and vitamin C. In the growth and development of pigs, it is more important that several of vitamins A, D, E and B vitamins are not synthesized in pigs and need to be supplied by feed. Generally, fat-soluble vitamins can be stored in the body in an appropriate amount, so that acute deficiency is not caused, and B vitamins are not easily accumulated in the body, so they are often prone to deficiency. Understanding the characteristics and functions of each major vitamin is important for guiding clinical use.
Vitamin A
The main physiological function is to maintain the normal function of the pig's respiratory, digestive and reproductive system mucosa; vitamin A is vulnerable to high moisture, glare and trace elements. When young pigs lack vitamin A, they are mainly characterized by loss of appetite, stagnant growth, neurological deterioration and excessive excitement, and paralysis and convulsions. When the sow is deficient, the sexual cycle is not normal, the formation of egg cells is reduced and the vitality is lacking. Even if the fetus is pregnant, it is easy to cause miscarriage and stillbirth, and deformed pigs. When the boar is deficient, the quality of the semen is reduced.
Vitamin D
Vitamin D is closely related to the absorption and utilization of calcium and phosphorus. Only with the participation of vitamin D can calcium and phosphorus be fully absorbed and utilized. The stability of vitamin D is easily affected by humidity, light and trace elements. Long-term lack of vitamin D can hinder the absorption and metabolism of calcium and phosphorus, cause bone calcification, and cause rickets in pigs, causing skeletal inorganic salts to dissolve in adult pigs and suffering from chondrosis. When pregnant sows are seriously deficient in vitamin D, not only the born pigs are debilitated and prone to rickets, but also give birth to deformed pigs.
It has the function of protecting the normal function of the reproductive system, and there is stillbirth in the absence of pregnant pigs. Vitamin E is related to the metabolism of nerves and muscle tissues. When it is severely deficient, it can cause muscle malnutrition. Vitamin E decomposition accelerates when exposed to light and heat.
B vitamin
In production practice, more important are thiamine (vitamin B1), riboflavin (vitamin B2), pantothenic acid (vitamin B3), niacin (vitamin PP) and vitamin B12. Among them, riboflavin, niacin, and vitamin B12 are more likely to be lacking, and pigs should be supplemented in their diets, which are sensitive to light. Riboflavin mainly affects the appetite, hair, body weight, etc. of pigs; niacin is necessary for normal physiological activities of skin and digestive organs, lack of vomiting, diarrhea and skin inflammation; vitamin B12 is involved in hematopoietic processes and protein synthesis. Too much B vitamins are harmless to the body, but they are not economical, which will increase the cost of farming.
Vitamins are very important for the production of pig farms, but their role cannot be overstated. To ensure the production performance of the herd, we must first ensure the supply of protein, amino acid and energy, and then convert the nutrients in the feed into pork products under the action of appropriate vitamins to obtain a good feed conversion rate, thus obtaining good economic benefits. . The addition of vitamins must ensure the actual needs of the farm and the cost of economic costs.
The importance of vitamins has been recognized, so most farmers will add it to pig feed, but no one really cares about how much is absorbed. The high temperature and high humidity in summer can cause animal stress, and the density of animals is high, which makes the animal's need for vitamins increase, so it needs to be added regularly. In addition, since many vitamins are unstable under high temperature, high humidity or strong light conditions, they are easily destroyed and damaged. It is especially important to select a multi-dimensional process with advanced technology and stable quality. Victoria's nano-segmentation and emulsification coating technology divides the vitamin particles of macromolecules into the body for absorption, and coats the unstable vitamins, making the vitamins stable and suitable for clinical use.
