You can't just look at the color, but combined with your pig's growth stage and economic use, pigs can use concentrated compound feed at different stages. Usually, pigs are in the early stage of growth and bone growth. There are certain requirements for mineral requirements, but protein, vitamins and carbohydrates are essential.
In the middle stage, it mainly develops muscles and needs a large amount of protein, and requires all kinds of amino acids to reach balance, and pay attention to the supplement of vitamins and minerals. In the later stage, fat is mainly deposited, and carbohydrate is required appropriately.
No matter what growth stage, pigs are required to feed the corresponding full price feed, because we know that the demand for nutrients in different stages of pigs is different.
A good or bad feed does not depend on the color, because we understand its composition, combined with the pig's growth stage to choose the appropriate feed.
Black concentrate may be added fat to make the color brighter, less dust, yellow may not be added. In a word, it is not correct to distinguish feed from color
