| prevalence of some internal parasites recovered at necropsy of thoroughbreds born in 1982 in kentucky. | a total of 89 thoroughbreds, 14 to 333 days old (born in 1982), were examined at necropsy for certain internal parasites during a 1-year-period, mar 1, 1982, to feb 28, 1983. the eyes of 73 of the horses and the cranial mesenteric arteries of 71 were examined. specific interest was on prevalence of parasites according to month of the year and age of the horses at necropsy. parasites recovered (first month-last month infected horse found) were as follows: thelazia lacrymalis (eyes) immature and m ... | 1985 | 3994134 |
| transmission of some species of internal parasites in horses born in 1990, 1991, and 1992 in the same pasture on a farm in central kentucky. | studies were conducted on transmission of natural infections of several species of internal parasites in horses born and kept on the same pasture on a farm in central kentucky. data for the first year (1989) of a 4 year study on this farm have been published recently. the present research represents the second (1990), third (1991), and fourth (1992) years of the investigation. the number of animals (n = 28) examined varied from eight born in 1990 to ten each born in 1991 and 1992. for each year, ... | 1994 | 8073609 |
| natural infections of strongyloides westeri: prevalence in horse foals on several farms in central kentucky in 1992. | during the period 28 february-1 july 1992, fecal samples were collected and examined for eggs of strongyloides westeri once from each of 382 horse foals (364 thoroughbreds, 16 standardbreds, one lippizaner, and one draft-type horse) in central kentucky. ages of the foals at the time of sampling ranged from 7 to 63 days (mean 22 days). the nine farms in the study were considered to have overall excellent deworming programs. none of the foals had been treated with an antiparasitic compound before ... | 1993 | 8291184 |
| prevalence of parasite eggs (strongyloides westeri, parascaris equorum, and strongyles) and oocysts (emeria leuckarti) in the feces of thoroughbred foals on 14 farms in central kentucky in 2003. | prevalence of internal parasites was determined by fecal examination for eggs and oocysts in thoroughbred foals in central kentucky in 2003. fecal samples were examined from 733 foals on 14 farms. this included 70 trips to the farms and a total of 2,346 fecal samplings. monthly collection of fecal samples was begun for four farms in february, six in march, three in april, and one farm in may. termination of the study for all farms was the end of july. a criterion was that the foals be at least 1 ... | 2004 | 14760526 |
| field studies on endoparasites of thoroughbred foals on seven farms in central kentucky in 2004. | fecal samples (n=1,584) for a parasite study were collected from thoroughbred foals (n=349), 28 to 330 days old, on seven farms in central kentucky during 49 monthly trips from may to october, november, or december 2004. the main purpose was to determine possible drug resistance of ascarids, also of strongyles, to ivermectin (ivm) and other commercially available compounds [fenbendazole, moxidectin (mox), oxibendazole (obz), and pyrantel pamoate]. in addition, interest was on prevalence of foal ... | 2006 | 16385405 |
| parasite field study in central kentucky on thoroughbred foals (born in 2004) treated with pyrantel tartrate daily and other parasiticides periodically. | foals (79), born in 2004 on three thoroughbred horse farms (c, m, and s) in central kentucky, were fed pyrantel tartrate daily, beginning at about 3 months of age. in addition, other parasiticides [fenbendazole (fbz), ivermectin (ivm) alone or with praziquantel (praz), oxibendazole (obz), pyrantel pamoate (prt), and moxidectin (mox)] were given periodically. all treatments were administered by farm personnel. over a 14-month period, from may 2004 to july 2005, collections (n=989) of feces were m ... | 2007 | 17013652 |
| prevalence of patent strongyloides westeri infections in thoroughbred foals in 2014. | the prevalence of patent strongyloides westeri infections was determined by examination for eggs in fecal samples collected from 513 thoroughbred (tb) foals between february 25 and june 3, 2014. the study was conducted with 244 colts and 269 fillies from 11 well-managed farms in central kentucky. foals ranged from 17 to 117 days of age and had never been dewormed. the mean prevalence of patent s. westeri infection was 30% (156/513 foals). this prevalence was substantially greater than historical ... | 2014 | 25149063 |
