Standard Reference Diets for Chicks
Many laboratories that use Leghorn- or meat-type chicks for studies in animal behavior, biochemistry, microbiology, nutrition, pathology, physiology, and toxicology need nutritionally complete standard reference diets. The use of standard reference diets that are well defined facilitates more valid comparison of information obtained from experiments conducted within and among laboratories. The diets shown in Table 10-1 have been used successfully in various laboratories and are presented as guides to those requiring such formulations. The isolated soybean protein, casein, and chemically defined diets contain some mineral and vitamin supplements not normally needed in practical diets.
Dextrose (glucose·H2O) rather than starch should be used in diets consisting primarily of purified intact proteins (such as isolated soy protein and casein) to obtain improved performance. Diets containing substantial quantities of dextrose and crystalline amino acids should be stored under refrigeration to minimize Maillard or Browning reactions. These chemically defined diets are intended for short-term use (1 to 3 weeks) and will not support maximum growth over an extended period of time.
