To provide protection for cows and calves during the winter and early spring months, temporary feeding sites are often used. While these sites can be used effectively, manure accumulation occurs in the areas around where they are fed over those months. There are several reasons for cleaning the manure from these sites but the most important is to lower the impact of nutrient and fecal bacteria runoff to surface water and reducing stable fly production. Continue reading “Clean winter feeding sites to reduce stable fly pressure”

Horn flies are blood feeding flies that impact production on cattle operations. Populations of these flies tend to peak in June. The hot dry days of summer tend to decrease the overall population. However, in late August to September as the temperatures begins to decrease and humidity increases, the horn fly population tends to peak again. Continue reading “Late Season Fly Control”
