We choose to keep the species from the midges and raise them with oysters. The extra crops are used as commercial medicinal herbs. Feeding medicinal meat should adopt different feeding methods according to different provenances. To do a good job of medicinal meat pupa should be to promote growth and weight gain, improve feed conversion rate, shorten the feeding period.
The nutrients in the feed must be comprehensive in order to promote the rapid growth of earthworms, increase lean meat percentage, and improve quality. Medicinal alfalfa feed should be properly matched and can also be used as a compound feed for chickens. The feed for medicinal crickets of more than 12 weeks old should contain crude protein 18% to 20%, crude fat 3%, crude fiber 4%, tryptophan 0.2%, lysine 1.0%, cystine 0.7%, methionine 0.35%, minerals such as calcium 2.8%, phosphorus 0.7%, salt 0.3%.
In addition, every 500 kg of feed also need to add vitamins and trace elements additives 5% to 10%, if the crude protein is insufficient, you can add fish meal or silkworm meal, blood meal, bone meal, lotus root meal, etc. instead. Feed 4 to 6 times a day, usually 2 times a day on the afternoon and evening. The feed can be divided into dry material, wet material and dry and wet. Most dry feeds are powdered or finely granulated, and generally have a water content of about 12%.
This feeding method is suitable for large-scale breeding or home-breeding, and has the advantages of saving feeding time and facilitating cleaning of cages. However, the palatability of the feed is poor, and the feed tends to spill out of the trough causing waste. The wet feeding method consists of mixing the mixed feed with green feed, water and the like. This law applies to small-scale breeding farms or family members raising fish. Its advantage is good palatability, feed is not easy to spill the trough, so the feeding costs are low, but the feed is hot and prone to spoilage, and at the same time, after ingestion of wet material will dilute the excrement, which not only affects the growth of adult clams, but also cleaning feeding Workmanship is expensive.
There is also a method of dry and wet feeding, that is, feeding powdered feed in the morning and at night and feeding a wet meal at noon. This method has the advantages of the above two feeding methods and overcomes its disadvantages. At the same time when feeding, sufficient drinking water should be provided. Drinking fountains can be made of tin-made small basins or ceramic basins. Cans can also be used as drinking fountains. The amount of drinking water can be controlled flexibly according to the temperature and the type of feed.
Chengyu needs careful management in the rearing process, and it can be scared and scared. Once he is frightened, he is nervous in the cage, so the adult female needs to be trained before laying eggs so that the behavior of the breeder can be improved. accept.
