引用美國(guó)加州大學(xué)著名動(dòng)物免疫學(xué)家Kirt Klasing曾說(shuō)過(guò)的一段話:
“ If animal health was selected as the functional endpoint instead of growth rate or reproductive performance, nutrient recommendations might change...Eventually target animal species need to be examined to determine specific concentrations of nutrients for optimal immunocompetence and health. ”
