A long-term cattle study involves the collection of urine, saliva and blood serum from replacement heifers to identify geneticrelated biomarkers relating to the reproductive ability of the heifers. The goal of this study is to provide producers with a way to determine the reproductive ability of a heifer at an earlier age than is currently available, thus reducing the expenses associated with keeping it through the breeding stage.
Commercial varieties of grain sorghum are being evaluated for their resistance to the sugarcane aphid, which is causing significant economic losses throughout the Southeast. Various insecticide treatments also are being evaluated. Results from this study can be used by producers to select varieties that are more resistant to the pest, thus decreasing risk and expenses.
The plant-back interval for clover following a herbicide application is being evaluated to help producers reduce the risk of damage caused to pastures by various chemicals. Residual levels of chemicals also can remain in the soil for several months after herbicide applications, affecting future clover plantings.
