“…(Giese et al., 1973; Laber et al., 2002), Ascarid spp. (Midttun et al., 2018; Ondrejková et al., 2012) are found to be associated with severe morbidity and mortality in pigs. Ascaris suum , Strongyloides , Trichuris suis and Strongyle have previously been reported from pigs in Nepal (Baskota & Shrestha, 2019; Sah, 2018).…”

Background Intestinal parasites have a significant impact on productivity of pigs. Additionally, presence of zoonotic parasites in pig faeces used as fertilizer and ingestion of raw or undercooked pork products originated from parasite‐infested pigs pose a risk to human health. Objectives The aim of the study was to estimate the prevalence and diversity of gastrointestinal (GI) parasites in indigenous pigs (Sus domesticus) maintained under traditional rearing system in Nepal. Methods Fresh faecal samples (n = 100) were collected from the pigs of varying age and sex maintained in 18 small‐scale farms in south‐central Nepal. Samples were processed using various standard methods and examined for parasite eggs, cysts or oocysts. Results Prevalence of GI parasites in indigenous pigs was 91%, comprising of 14 different genera of protozoans and helminths. Male pigs generally had a higher (97.5%) prevalence of GI parasites than females (87%). While 90% of the suckling and weaner piglets were positive for the GI parasites, all growers and 85% the adult pigs were infected with the parasites. Entamoeba spp. were the primary protozoans in all age groups. Strongyloides sp. was more prevalent helminths in suckling and weaner piglets, whereas Ascarid spp. were higher in both growers and adults. Triplet infection was higher (33.3%) in suckling and weaner piglets, while quadruplet and pentuplet infections were higher (p < .05) among growers (46.7%) and adults (30%), respectively. Conclusions The indigenous pigs harbour a higher prevalence and greater diversity of GI parasites. GI parasitism varies by sex and age of the pigs.

“…Sanchez-Vazquez et al (2010) recently demonstrated that infection by this parasite can decrease the animal's daily weight gain by up to 10%, and the feed conversion of pigs by up to 13% in the growing phase and at slaughter. A high occurrence of the parasite has also been reported in the herds of several countries, such as Slovakia, England and Poland (ČERNEK et al, 2012;SANCHEZ-VAZQUEZ et al, 2012;KNECHT et al, 2012).…”

“…Monitoring during slaughter allows for fast and inexpensive evaluation of herd health (ČERNEK et al, 2012), which in turn allows for the estimation of economic losses based on the number of discarded organs and on the number of infected animals. Sanchez-Vazquez et al (2010) recently demonstrated that infection by this parasite can decrease the animal's daily weight gain by up to 10%, and the feed conversion of pigs by up to 13% in the growing phase and at slaughter.…”

Among the parasites that affect pigs, Ascaris suum stands out for causing the greatest losses to livestock production systems. This parasite can be monitored during the slaughter of animals through the identification of "milk spots" or white patches on the liver caused by its larval migration. However, infection in the herd is usually subclinical, which is why the presence of this parasite in industrial pig production has been overlooked. The aim of the study was therefore to evaluate the occurrence of milk spots on the liver of animals slaughtered in the micro-region of Ponte Nova in the Zona da Mata -Minas Gerais, Brazil, and to associate these lesions with the time of year, herd size and source of origin of the animals. An evaluation was made of 1,069 lots, totaling 108,073 animals, based on data extracted from the Federal Inspection Service. The animals were slaughtered during the period of January 2011 to June 2013. Out of the total number of slaughtered animals, 10,535 (9.75%) tested positive for these lesions. Therefore, veterinarians and producers should be warned about the inefficiency of the deworming protocols that are used, and the need to develop and/or review control strategies for this parasite in production systems.

“…In Sweden, a survey of the six largest abattoirs demonstrated a rate of 2.5 to 6.5 percent milk spots in 729 herds (Lundeheim 2010). In Slovakia, 19,017 animals from 279 herds were inspected from 2000 to 2009 and a decrease in milk spot rates was seen from 39.5 to 6.9 percent (Ondrejková 2012). The authors attributed this decline to an increasing positive attitude toward parasite control within the Slovakian swine industry.…”
