the concentration of menhaden oil in the diet 

 fed, the quantity of oil consumed (A') could be 

 compared with the organoleptic scores (Y) ob- 

 tained for the pigs in each weight group (68.0, 

 79.5, 90.9 kg). 



RESULTS 



Tables 20, 21, and 22 give the weighted or- 

 ganoleptic scores obtained from the panel or- 

 ganoleptic tests. (Larger numerical values in- 

 dicate an unacceptable product or a trend toward 

 an unacceptable product.) 



Statistical analyses of these data indicate a 

 positive correlation between increased consump- 

 tion of oil and higher organoleptic scores for tis- 

 sues from pigs fed the oil until they attained 

 a body weight of 90.9 kg (Table 23). Removal 

 of the oil from the diet of the pigs at a body 

 weight of either 68.0 or 79.5 kg resulted in a
