Final answer:
If cattle and horses are sick with BRD or strangles, respectively, their liver will contain little to no glycogen due to the high energy demands of fighting these diseases, which depletes the glucose storage.
Step-by-step explanation:
If cattle have been sick with BRD (Bovine Respiratory Disease), or horses with strangles, they will have little to no glycogen in their liver. Glycogen is the storage form of glucose, which is used by livestock for energy. Diseases such as BRD and strangles can cause a significant energy demand on the body due to the stress and immune response they provoke. Consequently, the stored glycogen gets depleted. This can lead to a condition where there is not enough quick energy available for the animal’s needs, and if not addressed, it can have severe impacts on their health.
