OCAMPO, MARICEL LENTIJA. "PRELIMINARY STUDY ON THE EFFECT OF MOLD INHIBITORS ON THE MICROBIOLOGICAL QUALITY OF MIXED PORCINE FEEDS". Undergraduate Thesis, Bachelor of Science in Biology, Department of Biological Sciences, College of Arts and Sciences, Cavite State University, Indang, Cavite. April, 2008. Adviser: Dr. Yolanda A. Eagan
The study was conducted to: (1) determine the quality of formulated feed mixed with different mold inhibitors in terms of microbial load (mould, coliform, and Salmonella sp. counts, and total viable count) and aflatoxin level, (2) identify the best blend of mold inhibitor in inhibiting molds and (3) observe and identify the changes in physical properties of feeds mixed with mold inhibitors. This study was conducted at the Cavite Farmers Feedmilling and Marketing Cooperative (CAFFMACO) and Biological Science Department, Cavite State University, Indang, Cavite from November to December 2007. Four batches of feeds were formulated and tested in terms of microbial load and aflatoxin level after mixing with the different mold inhibitors. The experiment lasted for 4 weeks. Microbial counts were determined using Compact Dry Kits for yeast and mold, coliforms, Salmonella and total viable count and ELISA for aflatoxin analysis. The feeds maintained their physical quality for four weeks except for Treatment 1 with no mold inhibitor. The yeast and mold count of Treatments 2, 3 and 4 were totally inhibited at 4th week while Treatment 1 had a 140 cfu/g. The coliform count of Treatments 2 and 3 were also zero at 4th week while Treatments 1 and 4 had a 150 and 30 cfu/g, respectively. No Salmonella was detected in all the treatments. The total viable count of four treatments at 4th week was 320, 50, 20 and 30 cfu/g for Treatments 1,2,3 and 4, respectively. The average aflatoxin level, on the other handwas 5.825, 5.10, 3.975 and 7.10ppb for T1, T2, T3 and T4 respectively.
