Bibliography : leaves 53-61 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. lcc THEDIS 24285 24285 0 0 lcc 0 0 MMSU_MAIN MMSU_MAIN THESES 2024-12-09 7478 0 UTHESIS-7478 2024-12-09 2024-12-09 THEDIS Room Use Only
