Sheep are herbivores, but their dietary requirements are specific. While they can consume a variety of plants, lentils may not be the best choice for them. Lentils contain high amounts of protein and fiber, which can be difficult for sheep to digest. Additionally, lentils may cause bloating and discomfort in sheep, potentially leading to health issues. It is advisable to consult a veterinarian or animal nutritionist before introducing lentils into a sheep’s diet to ensure their well-being.
