Although corn is the main feed for pigs, the quality of protein contained in corn seeds is relatively poor, and the overall protein content is somewhat low. If the protein content in the diet is not enriched, the normal growth of pigs cannot be guaranteed. In order to meet the normal requirements of the pig's body for protein, it is necessary to add an appropriate amount of protein feed to the pig's diet. Generally speaking, adding rapeseed cake or bean cake is a more convenient choice, but it is necessary to pay attention to the addition amount not to exceed 15%. If it is to feed the piglets, it is also necessary to add about 5% of fish meal.
