Silkworm sand feed saves money on environmental protection
Silkworm excrement, which is the excrement of feces, has a high nutritional value, crude protein content is 15.4%, second only to bran, higher than rice bran and grass, it is a good feed. The use of silkworm sand as feed for livestock and poultry not only saves culture costs, but also reduces environmental pollution and achieves good results.
The specific advantages of feeding different livestock and poultry are as follows: 1. Feeding pigs can save a large amount of concentrate feed, pigs gain weight quickly and have a high slaughter rate per unit time. After the sow feeds silkworm sand, the amount of milk secretion increases. 2. Feeding sheep can increase wool production and lactation, and sheep hair can reach more than 14 cm. 3. Feeding cattle can make cattle hard-working and have good constitution. 4. Feeding rabbits can increase rabbit fat accumulation and moisture content. 5. Feed chickens, add 5% of silkworm sand in the chicken feed, and have obvious effect on egg coloring. 6. Feeding fish can cause fewer fish diseases and rapid growth. It can produce 100 kilograms of fresh fish for every 1,000 kilograms of silkworm sand.
However, it should be noted that although the nutritional value of fresh silkworm sand is high, it cannot be stored for a long time, and it is easy to spoil and mold. In order to facilitate use for a long period of time, it is necessary to dry the silkworm sand to make the moisture content below 15%, or to silage it with large cylinders, cement pools, etc., and compactly compress and compact the heap to facilitate the use of lactic acid fermentation. At the same time, we must also pay attention to the fact that the silkworms and sands generally contain the source of silkworm diseases, and the silkworm sand used as feed should be kept away from the sericulture room.
