Stress, surgery, illness—these factors greatly affect the appetite of animals, often leading them to stop eating grass or fodder. Overfeeding grains, substandard feed (moldy fodder), or excessive use of antibiotics can disrupt the balance of microorganisms (microflora) responsible for digestion in the rumen, causing indigestion in animals. Additionally, liver issues can further weaken digestion.

In dairy farming, about 70% of expenses go towards animal feed. Traditional fodder provides essential proteins, fats, carbohydrates, vitamins, and minerals to livestock. However, even the best quality feed can be ineffective if it isn't fully digested and absorbed by the body.
