Don Mariano Marcos Memorial State University - North La Union Campus, Sapilang, Bacnotan, La Union.https://lakasa.dmmmsu.edu.ph/handle/123456789/983The use of probiotics is being promoted as of today to improve the digestibility of feeds. Hence, this study on the use of 2% Lactic Acid Bacteria Serum (LABS)-Fermented Yellow Corn as supplement to commercial feed was conducted from November 7, 2012 to January 7, 2013 at the Piggery Project of Don Mariano Marcos Memorial State University, North La Union Campus, Bacnotan, La Union. Twenty weanlings were used in the study. They were distributed into two treatments with ten replications following the lay-out for t-test. The data gathered were analyzed using t-test. Result of the study revealed that the performance of the pigs given 2% Lactic Acid Bacteria Serum-fermented yellow corn as supplement performed comparably with the pigs fed with unfermented yellow corn supplemented to commercial feed in terms of final weight, average daily gain in weight, feed conversion ratio and profit above feed, medicine, stock, and lactic acid bacteria serum cost.en-USThesis
