With summer in full gear it is a good time to evaluate how your fly control program is working. When horn fly numbers are greater than 200 flies per animal we see significant production losses associated with blood loss and decreased feed consumption. Numbers of face flies and stable flies are harder to assess because they only spend a small amount of time feeding on cattle but are still significant pests.
Significant presence of mud can increase energy requirements by as much as 30%. Wading through mud burns more calories, resulting in reduced gain for developing breeding stock and fed cattle as well as reduced milk production for cows. Confounding things further, cattle to tend eat less by simply avoiding putting in effort to get to feed.
The environment inside our livestock and poultry houses is important for maintaining a productive and healthy herd or flock. Ventilation or fresh air exchange is important to remove undesirable moisture and noxious gases during winter months and in summer, make sure the indoor temperature is not too much warmer than outdoors.
