Abstract
Stocker Steer Gains and Fly Numbers as Impacted by Burn Date and Type of Mineral on Tallgrass Native Range
Highlights
Essential oils/spices have been offered as a potential method to control insects in cattle (Showler, 2017; Massariol et al, 2009), alter rumen microbial population (Elcoso et al, 2019), and replace feed antibiotics, all of which may improve production responses in beef as well as dairy cattle
This study aims to evaluate effectiveness of two operational management systems for steer gains and fly control
APR-SPICE steers had a greater number of flies on weeks 8, 10, and 11, corresponding to a time when mineral intake averaged 72% of the formulated intake
Summary
Essential oils/spices have been offered as a potential method to control insects in cattle (Showler, 2017; Massariol et al, 2009), alter rumen microbial population (Elcoso et al, 2019), and replace feed antibiotics, all of which may improve production responses in beef as well as dairy cattle. Grazing stocker cattle on cool-season annual grass pasture or summer pasture did not show improvements in gains when cattle received a cinnamon and garlic essential oil product by either free-choice or handfeeding (Beck et al, 2017). Other studies at Kansas State University have found that the feeding of spices in mineral have increased gain in growing cattle on grass (Farney, 2020a; Farney, 2020b). Smoke management plans are important for the state of Kansas as high smoke production in April creates smoky conditions that drift to large metropolitan areas. If gains and plant population changes are not too different when burning in March instead of April, it would provide the opportunity to develop a smoke management plan that allows for an increased burning season to dilute a single month’s smoke
