The objective of this study was to provide contemporary data on the epidemiology of gastrointestinal nematode parasite infections of grazing yearling beef cattle in the province of Saskatchewan. Fecal samples ( = 1290) were collected over 4 time periods during the summer grazing season from 21 separately managed groups of cattle. Fecal egg counts (FEC) were estimated using generalized estimating equations with a negative binomial distribution with log link function, adjusting for clustering of samples within each herd for each time period.
