What are the precautions for feeding pigs with distillers' grains? Farmers should keep them in mind
Distillers' grains are divided into baijiu distillers' grains and beer distillers' grains. Baijiu distillers' grains have 32 percent dry matter, 3.36 MJ per kg digestible energy, and 7.5 percent crude protein. Beer distillers' grains have 14 percent dry matter, 1.43 MJ per kg digestible energy, and 3.6 percent crude protein. Whether baijiu distillers' grains or beer distillers' grains, they must be fed fresh; if piled up for a long time, they will become moldy and spoiled. If there is any left over, it can be put into a large vat, trampled down firmly, and soaked in water. Pregnant sows and lactating sows are not suitable for feeding, to prevent miscarriage, stillbirth, and so on. For meat pigs, it generally does not exceed 20 percent of the daily ration.
