Why do rabbits eat their own soft droppings?

In the process of raising domestic rabbits, we see that the hard fecal pellets they excrete are formed through a second round of digestion. Domestic rabbits eat grass and feed during the day, and excrete soft droppings at night or before dawn, and as soon as the soft droppings are excreted, they immediately eat them, and only through the second round of digestion and absorption are the residues formed into hard fecal pellets and excreted from the body. When domestic rabbits eat the soft droppings they excrete at night, it is not coprophagia caused by a lack of some nutrient in their body, but a normal physiological phenomenon. This instinct of domestic rabbits has two major benefits: first, it can keep the rabbit hutch and rabbit farm clean and hygienic; second, it can achieve the effect of making full use of the feed. Therefore, in the process of raising domestic rabbits, if you find them eating the soft droppings they excrete at night, do not disturb or stop them, otherwise it will disrupt the digestion pattern of the domestic rabbits and affect their normal growth, development and health.
