As modern animal husbandry is driven by commercial factors, in order to obtain the best economic benefits, there are various stress factors in the living environment of various animals, such as crowding, environmental temperature and humidity, and air quality. When animals are stressed, metabolism of various substances in the body is accelerated and the demand for various vitamins increases. If a sufficient amount of vitamins cannot be provided, the animal will be in a sub-clinical state, affecting growth and development, and will develop severe disease. Compared with the above-mentioned losses, investment in the addition of a sufficient amount of vitamins is very small, which is in line with the principles of modern commercial behavior.
When animals are in a special physiological stage, the demand for vitamins will be higher than usual, such as childbirth, disease and so on.
In summer, high temperature and other factors lead to a decrease in feed intake, while high temperatures require higher vitamins, requiring that the amount of vitamins in feed be doubled.
As the quality of various individual vitamins used in a general feed mill is different, there will be certain losses, such as overdue, static electricity, storage conditions, mixing uniformity, and carrier quality. At present, one of the biggest causes of animal husbandry loss is the fact that the uniformity in the breeding process is not high, affecting the uniformity of the factors. In addition to management factors, whether the various micronutrients in the feed are evenly mixed or not is a big factor. The important thing is vitamins. Because animals require vitamins every moment of the metabolic process, water-soluble vitamins do not accumulate in the body. At present, China's testing methods and standards for various water-soluble vitamins have not yet been unified.
Because the raw materials used in feeds are of different quality, such as high levels of urease in soybean meal, affecting the absorption of other nutrient factors, it is necessary to multiply the amount of added vitamins by a certain safety factor.
Taking into account the above factors, after calculation, comparing the increase in the cost of adding more vitamins and the increase in the benefits of normal growth and development of animals, to find the best efficiency / cost ratio, the use of high-vitamin content of the feed will make each feeding The feed conversion rate in the field is further increased.
