Silkworm sand is also silkworm feces. The nutritional value of silkworm sand is relatively high, with 14.1% crude protein, crude fat 2.14%, crude fiber 19.7%, and nitrogen-free extract 44.5%. In addition, it also contains nutrients required for the growth and reproduction of livestock such as vitamins A and E, and can completely replace part of green feed or silage.
The silkworm sand is fragrant and delicious, and pigs love to eat it. Tests have shown that adding 10% of silkworm sand to formulated feed is basically the same as adding 30% of bran. Under normal circumstances, it is advisable to add 10%-15% of the diet to the diet. If the amount is too large, it will affect the palatability and the effect of use.
Fresh silkworm sand can be directly added to the feed to feed the pig. If the feed is not finished for a while, the silkworm sand should be dried or dried in time and stored for future use to prevent fermentation. Dried or air-dried silkworm sand is soaked with fresh water for 4-6 hours before feeding, and then softened and fed to pigs.
Note that silkworm silkworm can not be used for feeding pigs. Dead silkworms cannot be directly fed to pigs, but they can be processed by cooking.
