Correct understanding of the minimum needs and appropriate supply of vitamins

Nowadays, research on vitamin nutrition has developed to the level of molecular biology. In recent years, the newly discovered additive effect (additionalef-feet) has far exceeded the traditional category of prevention and treatment of vitamin deficiency. The growing challenge in the aquaculture industry has prompted people to rethink the appropriate addition criteria for vitamins in feeds in order to achieve healthy, productive and profitable farming goals.

As people's understanding of the role of various vitamins is deepening, especially the continuous development of farming technology and people's expectations for the input and output of the aquaculture industry, the recommended dosage of vitamins has been continuously revised. The addition of vitamin nutrition not only prevents the vitamin deficiency of livestock and poultry in the traditional sense, but also solves the support for optimal feeding in the commercial operating environment.

1 vitamin needs to re-recognize FS7 China feed industry information network - based on feed, service animal husbandry

A recent typical test report revealing the difference between minimum nutrient requirements (NRC recommended) and appropriate supply is published by Stahy et al in 1995. He added different doses of multivitamin premix (including vitamin B2, niacin, pantothenic acid, folic acid) to the pigs, which were 70%, 170%, 270%, 370%, and 470%, respectively, of the NRC recommendation. No significant increase was observed in the test group with the lowest added amount. This result confirms that the benefit of increased vitamin supplementation is not only to alleviate the deficiency. The test results also found that this advantage is more pronounced in the growth of high-yield lean pigs than in medium lean pigs. This result also indicates that the optimal addition of B vitamins is satisfactory for the deposition of proteins. Therefore, it is recommended to adjust the appropriate addition amount of B vitamins in the pig feed for growth stage to 200%-300% of the NRC recommended amount.

The rapid development of biotechnology has created many new miracles, and the emergence of new high-productivity varieties has promoted the advancement of nutrition research. Among them, the demand for vitamins varies greatly, and the reasons may be as follows: 1 the selection of new breeds of livestock and poultry makes the demand for various vitamins change; 2 the internal and external stress factors affect the animal's need for various vitamins; 3 The market's quality requirements for products also limit the amount of vitamins supplied.

2 The current misunderstanding of the use of multivitamins on the market FS7 China feed industry information network - based on feed, service animal husbandry

The development of China's feed industry is still a long way from the promotion and application of many new technologies. The uneven quality of feed hinders the development of the breeding industry in a high quality and efficient manner. There are many misunderstandings in the understanding of vitamins in particular, although it has been recognized that vitamins are one of the essential nutrients for livestock and poultry, but they do not meet the production needs of animals. At present, the shortcomings of the general-purpose multivitamins for livestock and poultry on the market are mainly due to the lack of consideration of the differences in the types, physiological stages and production uses of livestock and poultry, resulting in excessive vitamins in the livestock and poultry diets, and other vitamins. insufficient.

Regarding the amount of vitamins, different experts have their own opinions, and it is difficult to have a unified conclusion. In short, to meet the nutritional needs of animals for vitamins, the production of excellent livestock and poultry products is everyone's common aspiration.

3 re-evaluate the role of vitamin production FS7 China Feed Industry Information Network - based on feed, service animal husbandry

In the past, people's understanding of vitamin supply was mainly based on whether there was a deficiency. We aim to raise livestock and poultry in order to obtain their final products. More and more consumers are beginning to pursue the intrinsic quality of the final products of livestock and poultry, such as flavor, color, nutrition, health care, health and safety. In addition to the nutritional effects, vitamins can also improve eggshell quality, egg yolk color; enhance the freshness of meat, extend shelf life; improve reproductive performance. Therefore, it is appropriate to evaluate the supply of vitamins, not only to consider the feeding effect, input-output ratio, but also to determine whether it meets the needs of the market and achieve the best benefits.
