Polynomial regression analyses of these data in- 

 dicate that the incorporation pattern of the fatty 

 acids (20:5 co3, 22:5 co3, 22:6 aj3) was quad- 

 ratic, with the rate of deposition being greater 

 at the lower levels in the diet. Removal of men- 



haden oil from the diet of the pigs at the two 

 body weights, 68.0 or 79.5 kg, did not alter this 

 pattern markedly. The principal changes were 

 a reduction in the relative degree of significant 

 response (O.Ofr to 0.059r) and an alteration
