Numbers of gastrointestinal helminth eggs of Wyoming cattle in two surveys: 1957 to 1961 and 1973 to 1977.
From 1973 to 1977, a survey of internal parasites in Wyoming cattle was conducted via fecal analyses of 1,490 beef cattle. Sugar flotation techniques were used, with a factor of 2 times the actual egg counts. The prevalence of internal parasites of beef cattle in this survey was compared with that in a previous survey conducted on Wyoming beef cattle from 1957 to 1961. Results of analyses indicated no true change in mean eggs per gram of feces (epg) as follows: calves, 14 epg in 1961 and 20 epg in 1977; yearlings, 29 epg in 1961 and 19 epg in 1977; and adults, 22 epg in 1961 and 21 epg in 1977.
