The study was conducted to investigate the occurrence of internal parasites in
pigs in selected towns of Ilocos Norte. Specifically, it aimed to determine the
prevalence of different internal parasites through fecal collection and assessment of
fecal egg per gram (EPG); identify the type of helminths prevalent in swine; determine
the type of internal parasitic infection (single and mixed) through descriptive analysis;
and identify the risk factors of internal parasite infection by correlating the farm profile
and management practices to the output of fecal samples collected.
A total of one hundred (100) swine raisers were interviewed regarding the farm
profile and their management practices, equivalent to the fresh fecal samples to be
obtained. Fecal samples were subjected to flotation method and modified Mcmaster
method using the standard keys of Thienpont et al. (1979) to identify the helminths
found in the samples. Eggs were examined under the microscope, and qualitative and
quantitative data were necessary to record the results of this study. The data were
analyzed using the Statistical Tool for Agricultural Research (STAR) software.
Four nematodes were commonly found in the growing to finishing ages of pigs,
namely Ascaris suum, Oesophagostomum spp., Strongyloides sp., and Trichuris suis.
Through positive samples in the EPG of the modified Mcmaster method, it was
identified that A. suum (75.76%), Oesophagostomum spp., and Strongyloides sp.
(60.61%) are more prevalent in the City of Batac, however, T. suis is more prevalent
Vintar (52.38%) and Dingras (52.94%). On the other hand, in terms of the degree of
infection, mixed infections have a 57.74% rate, which is more prevalent than single
infections, which have 43.66%. Moreover, the risk factors for increasing the EPG of
internal parasites are sex of the animal, production system, floor type, feed types,
waterers used, fecal removal, cleaning the pens, the practice of deworming, dewormers
used, the person administering the dewormer, and consultation with a veterinarian.
Based on the findings, to improve the connection of internal parasites in swine
raised in Ilocos Norte, the following actions are recommended: (1) consultation with
veterinarians regarding the proper use and treatment of dewormers for the pigs; (2)
implementation of regular hygiene and sanitation to reduce the possible infections of
internal parasites in the pigs; and (3) further investigations in broader-scope studies in
Ilocos Norte to better justify more that internal parasites that affect the production of
the farm.
