Abstract
The effects of cold expusure (5°C) on feed intake, growth rate, plasma FFA, liver and abdominal muscle fat oxidation etc. were studied.
The 5°C groups of rats intaked more of all diets than 20°C groups. The growth rate and F. E. R. (feed efficiency ratio) at 20°C were greater than 5°C. The plasma phospholipid levels, liver and abdaminal muscle fat oxidation leveis rose in rats maintained at 5°C.
The oxidation of fat was closely related with dietary protein levels.
