当今水产养殖发展迅速,但伴随着集约化养殖程度的不断加深,环境问题、饲料短缺问题、食品安全问题、药物残留问题等日益凸显,在养殖过程中不仅要关注水产动物的营养需求,更需要从饲料本身关注养殖动物的健康状况。通过在饲粮中添加外源核苷酸,以提高水产动物生长性能,改善免疫力及抗病力,维护肠道健康。酵母水解物中核苷酸含量高,是优质的外源核苷酸来源,具有广阔的应用前景。 Aquaculture is developing rapidly nowadays. However, along with the deepening of intensive farming, environmental problems, feed shortages, food safety issues and drug residue problems have become increasingly prominent. It is even more necessary to pay attention not only to the nutritional needs of aquatic animals during the breeding process From the feed itself concerned about the health status of farmed animals. By adding exogenous nucleotide in the diet to improve the growth performance of aquatic animals, improve immunity and disease resistance, maintain intestinal health. Yeast hydrolyzate nucleotide content is high, is a source of high-quality exogenous nucleotide, has broad application prospects.
