  • An encyclopedia should properly encompass the totality of human knowledge, or at least of some particular sector of it. Not so many years ago it would have been possible to contain all that was known of animal nutrition in a book the size of this, for the science of nutrition is young, but such has been the pace of its growth that that is no longer possible. The nutrition of farm animals is a complex subject, reaching into biochemistry, physiology, pathology, veterinary medicine, animal husbandry and agriculture and even, as evidenced in the following pages, beyond those disciplines.

  • Electrolytes: solutes which carry electrical charge - these compounds are at least partially ionized 1. Strong Electrolytes = solutes almost completely ionized 2. Weak Electrolytes = solutes only partially ionized .Acids and Bases - electrolytes (can be weak or strong) 1. Bronsted-Lowery Theory: acids are proton donors bases are proton acceptors 2. Strong Acids and bases almost completely ionized 3. Weak acids and bases (poorly ionized). See Table 6-2 (memorize strong acids and bases)

  • The solubility of a partially soluble salt is decreased when a common ion is added. Consider the equilibrium established when acetic acid, HC2H3O2, is added to water. At equilibrium H+ and C2H3O2- are constantly moving into and out of solution, but the concentrations of ions is constant and equal. If a common ion is added, e.g. C2H3O2- from NaC2H3O2 (which is a strong electrolyte) then [C2H3O2-] increases and the system is no longer at equilibrium. So, [H+] must decrease.
