Did the instructor ignore nucleotides?

Introduction: the industry believes that the difficulty of selection and high price are the threshold for nucleotides to be widely used in teaching materials 6ys Southern rural news (reporter Sun Liang) "many formulators have considered the conventional nutritional needs of piglets when designing the formula of teaching materials, but they often neglect some special functional materials, such as nucleotides," said Gary Boyett, a consultant at the first domestic and foreign development summit forum of teaching materials held in Guangzhou on June 14 The formula design and piglet nutrition of the teaching trough material products have become a hot issue of concern to 500 participants from all over the country According to Dr 6ys Garry, nucleotides have a very good effect on the growth and development of young animals as well as their immunity Many formulators have noticed that in infant milk powder, high-grade milk powder brands will also have a high proportion of nucleotides added Many scholars believe that any animal in the rapid growth period, stress period, immune compromise period, low energy intake, the need for nucleotides will increase The weaning stage of piglets is good at the intersection of these four periods, and has the characteristics of these four periods, so the need for nucleotides is more prominent Generally speaking, the content of nucleotides in feed is not included in the routine analysis of feed, while the routine feed materials, although containing nucleotides, can not meet the needs of animals At present, there are many nucleotide products for piglets in the market, but how to choose them has become a headache for the formulators On June 14, Hu shoule, the boss of both pig raising and feed production, joked at the meeting "Today, there are also many additive suppliers who operate this kind of products They are the only ones who are most clear about how to use and how to choose their own products." Although the price of 6ys is only about 20 yuan / kg, the cost of nucleotides in teaching materials is not cheap Henan biyuntian Feed Co., Ltd is a "rookie" of local preliminary materials Yan Jun, general manager of the company also attended the meeting as a guest He told Nanfang rural daily that the amount of such products used in the early materials is relatively large, generally in 10kg-15kg / ton feed, and even in 20kg / ton feed added by some manufacturers According to Dr 6ys Gary, because of the problems of selection and price, nucleotides have not been paid attention to by the majority of teachers Dr 6ys Gehry also suggested that the selection of raw materials should not be too single and modeled We should open our mind and select as many varieties of raw materials as possible instead of relying on additives, so as to meet some of the main nutritional needs of animals The first-line pig farms should not only be equipped with special veterinarians, but also have professional nutritionists, so as to provide good breeding and solutions for the pigs in the farms at any time, which is ignored by many large-scale pig farms at present 6ys at the forum, some experts thought that the current formula was too dependent on the surface indicators of feed materials, and did not pay attention to its real quality, such as the composition of various elements, digestible absorption and utilization rate At present, the formulators of the major teaching tank material enterprises have some homogeneity in making the teaching tank material formula Even if the same formulator, in different regions and different levels of pig feed allocation is also mostly the same formula 6Ys
