Vitamins are essential to maintain normal function of animal material, if the lack of poultry feed in any vitamins, are easily led to the occurrence of certain diseases and cause economic losses. In recent years, poultry production practices adopted throughout the exploration and scientific research departments for test, confirmed that the poultry feed, the main reason for the lack of vitamins or less in the following areas.
Improper feed ratio
Since different plants and animals in the vitamin content, such as liver, carrots, yellow corn contains more vitamin A; dry yeast and proofing and hay in the multi-vitamin D; big cake (cake), cotton seed cakes are containing Vitamin E more; soy, grains and fish meal are vitamin B1, B2 and more; fish meal, bone meal and liver are more than vitamin B12. Therefore, in the preparation of poultry feed, we must understand the content of each of Vitamin raw materials, but also note that the proportion of feed mix should be reasonable, pay attention to the balance of vitamins.
Different feed types
Folic acid, niacin, biotin, etc. in different feed their different biological potency. Such as folic acid powder mixed feed in the more stable, and trace elements in feed particles or other combination of choline chloride is not stable enough.
Feed processing and storage for too long
All the vitamins in animal feed has time to potency, most of the stability of vitamin in the 3 months to 4 months is better. Therefore, when using the feed or added vitamins, must pay attention to the factor of storage time.
Abuse of antibiotics
As the use of antibiotics and easy to reduce the poultry intestinal microorganisms in vitamin synthesis, resulting in vitamin deficiencies. In addition, some vitamins will be humidity, temperature, pressure, light, pH, trace elements, antioxidants, reducing agents and compounds, and other factors. For example, vitamin A and D vulnerable to moisture, temperature, trace elements, factors such as the destruction of fat rancidity; vitamin B1 are vulnerable to heat, oxidants, reducing agents, pH and other effects.
Domestic vitamin manufacturers have produced a single vitamin products such as vitamins A, E, D3, B vitamins, etc., but also how to use multi-vitamin products. To this end, the use of vitamin, the light of feed raw materials, Huanjingtiaojian and nutritional needs of poultry science Diaozheng Deng Fangmianjinxing, Shi Tian Jia both Chongfenliyong into the vitamin, but also to meet the nutritional needs of poultry, can be best economic benefits.
