Common Perma Cake as Protein Supplement in Feeding Bacon-Type Pigs

The trial was conducted in the same condition of basal diets for commod-ity Bacon-type pigs with additives 6%,8%and 10%of common perilla cake added to thethree treatment groups(group A. group B,and group C)respectively,and with 8%of ad-ditive rapeseed cake was served as the control.

There was a significant difference between Groups A,B,C and the control group(P<0.01) ,and also,there was a significant difference between group A and the controlgroup(P<0.05).In comparison with the control,the less feed consumed for weight gainper one kg in the trial groups A,kand C was 0.3,0. 4 and 0. 6kg so that feed conversionefficiency of groups A, B and C increased by 7.9%, 10.5%and 15.8% respectively,groups A,B and C achieved more net profits of 171 yuan,216 yuan and 340 yuan respec-tively higher than that in the countrol.
