Pigeons are rich in protein, and protein is one of the important nutritional sources in meat. In contrast, the protein content of old pigeons is relatively low, because their body metabolic rate decreases with age, which leads to the decrease of muscle tissue.
The fat content in old pigeons is relatively high, because the accumulation of fat in animals will increase with time. On the contrary, the fat content of squab is low, because its meat is tender and soft, and the fat content is relatively low.
Young pigeons are rich in vitamin B group and vitamin E, while old pigeons are mainly vitamin B group. Vitamin B helps to accelerate human metabolism and promote health, while vitamin E has antioxidant effect and can delay aging.
Old pigeons are in a state of atrophy, and their metabolic capacity is relatively low, so it is difficult to quickly absorb nutrients in food. Pigeons, on the other hand, are in the growing period and have strong metabolic ability, so they can better absorb the nutrition in food.
