What is the effect of cow age on carcass quality?

The general rule is that the older the cow is, the worse the carcass quality of the cow is. The carcass quality of Chinese yellow cattle is best in the 2~3 year old stage. The proportion of carcass fat and lean meat in beef carcass components varies with different ages. With the increase of cattle fattening time, the amount of fat in cattle gradually increased. It has been determined that the proportion of body fat in cattle aged 1 to 13 months is small, and after 14 months of age, the amount of fat deposition and deposition speed increase significantly. By 24 months of age, the percentage of fat in cattle is 8 months of age. 3 times more. At the same time as the amount of fat gradually increased, the percentage of lean meat in the carcass gradually decreased. At the age of 16 months, the lean meat accounted for 60% of carcass weight. By the age of 24 months, the lean meat accounted for only 56% of carcass weight. As the calf age increases, the percentage of bone weight and lean weight in carcasses decreases, and the proportion of fat in carcasses rises.
