Fish buds for making and feeding
Grow feed is made from grains such as barley and rice. In the absence of spring or green fodder, grain sprouts can not only replace part of the green feed, but also can supplement the deficiency of vitamins, promote fish growth, and enhance disease resistance. In particular, it is important for the prenatal cultivation of grass carp, clams, cockroaches, and other food-eating fish, and it can increase spawning rate, fertility rate, and survival rate. Now the production and feeding methods of the grain buds are described as follows: 1. Production of cereals such as barley, rice, etc. is screened to remove impurities, washed and dried, and soaked in warm water of 25°C-30°C for a day and night. After the seeds are inflated, remove them and spread them in a wooden tray or other water filter, with a thickness of 3-5 cm, covered with gauze or sacks, and kept at room temperature at 18-25°C. Every day and night spray warm water of about 30°C 3-4 times, while slightly turning, 2-3 days after the hair roots and germ can grow, then remove gauze or sack film, about 5-7 days, shoots grow, The length of the bud can be controlled as needed to feed the fish. Second, feeding the grain is rich in carotene, riboflavin, vitamin E and vitamin A and other substances, but the type of vitamin it contains varies with the length of the bud. Therefore, it should be grasped as needed when feeding. Bud 0.5-1 cm in length, high vitamin E content, suitable for broodstock prenatal training, the male fish can increase lust, improve semen quality, for the female fish to promote egg development, improve egg fertilization rate. When the buds are 2-3 cm long, they contain rich vitamin B, which can promote appetite, help digestion, and are suitable for breeding adult fish. When the shoots are 3-10 cm in length, vitamin A accounts for a large proportion and plays an important role in the growth and disease resistance of fish. It is a good feed for the cultivation of adult fish, broodstock and broodstock. The use of grain bud fish is generally 3-4 kg of grain buds and 1 kg of fish. The grain buds can be fed directly as feed, and the daily feeding amount is 3% to 8% of the fish's body weight. It can also be used as a vitamin additive in combination with other feeds to increase the utilization of the feed. After germination and feeding fish, the grain has the advantages of wide raw materials, simple production, rich nutrition, strong palatability, convenient feeding, and low cost. In addition, it can also alleviate the contradiction between the lack of refined and green feed, and it is a kind of fish feed that is worth promoting.
