[Studies on the additive character of amino-acid absorption data obtained from pigs. 2. Studies using regression...

The first communication in this series (MEIER et al. 1973) reported the results of studies on the additive character of amino acid absorption data from pigs which were based on the use of the classics technique. In order to verify these results the studies were repeated, partly with the same components using regression techniques. The present studies on the additive character of amino acid absorption data showed that the additive character of these data can also be established in pigs. Moreover, the results of these investigations indicated that studies on the additive character of amino acid absorption values may be carried out by using the classical method. In performing studies of this kind attention should be paid to the fact that the rations tested should be such as to meet or nearly meet the maintenance needs of the animals.
