In fact, vegetarian animals occasionally eat meat, and there are many videos of vegetarian animals eating meat on the Internet. There are many reasons for this phenomenon. Although eating meat by vegetarian animals will cause digestive burden and incomplete nutrient absorption, it is not completely unabsorbable after all. Eating too much will kill probiotics in the gastrointestinal tract, but this kind of excessive consumption is rare in the wild. Deer are the most common phenomenon in the wild. There are videos of deer eating bones on the Internet, and there are videos of deer eating birds on the Internet. The most likely reason for this phenomenon is the lack of trace elements in the body, including but not limited to pica. There is no need to explain the phenomenon of animal pica, or simply eating indiscriminately. The meat and bones of other animals are good supply stations for trace elements such as protein and calcium, even for vegetarians in harsh living environment in the wild. For animals with horns, eating bones is beneficial to the development of horns, and this phenomenon of eating bones is more common in such animals. In addition, in animal husbandry, a small amount of meat or insects will also be added to animal feed. The most special is the Oroqen horse. A long time ago, when the forage reserve could not ensure that these horses could survive the winter, the Oroqen people would cut some beef and mutton into pieces and cook them to make them easier to digest. Ma Ziran, who adapted to eating meat and absorbed it better, survived. Nowadays, the Oroqen people not only feed horses meat in winter, but also feed them some meat before hiking, which is said to increase their endurance.
