矿物质、维生素是鱼类生长发育不可缺少的活性物质,在鱼体及饲料中含量虽少,但对鱼类的生长和健康关系极大。在高密度集约化养殖条件下,在鱼类饲料中合理地添加将会使养鱼效果和经济效益得到提高。因而矿物质、维生素预混料成为鱼饲料中的一种必需成分。 草鱼是我国传统的主养经济鱼类。本试验旨在探讨矿物质和维生素间组合使用效果以及合理配比,筛选对草鱼种生长较适宜的矿物质和维生素预混料,为生产实践提供指导。
Minerals, vitamins are indispensable for fish growth and development of active substances in the fish and feed content is small, but the growth and health of fish has a great relationship. Under intensive intensive farming conditions, the reasonable addition of fish feed will result in improved fish culture and economic benefits. Thus, minerals, vitamin premixes become an essential ingredient in fish feeds. Grass carp is our traditional main economic fish. The purpose of this experiment is to explore the effect of combination between minerals and vitamins and to rationally match the mineral and vitamin premix which is suitable for the growth of grass carp species and provide guidance for production practice.
