Benefits and Methods of Feeding Fish by Germinating Feed

According to local practice, the use of germination feed (ie, grain germination, the following referred to as the grain buds) to feed fish, not only has the advantages of rich nutrition, good palatability, and promoting the promotion of weight gain. And it can significantly improve the quality of fish, cooked meat tender, sweet and delicious. In addition, the grain bud feeding fish can also alleviate the contradiction between the lack of concentrate feed and green fodder, and has rich raw materials and convenient feeding, which is worth promoting.

First, the benefits of germinating feed for feeding fish

The germination of cereal grains has significantly improved and improved the original nutritional structure and value, and wolfberry has become a good feed for supplementing livestock vitamins. Studies have shown that: The use of grain bud fish can promote the transformation and metabolism of fish nutrients, and enhance the skin antibacterial ability, especially for grass carp, oysters, clams and other food-eating fish have an important role in prenatal cultivation, can increase spawning Rate, fertilization rate and survival rate. The variety of vitamins contained in the grain bud differs depending on the length of the bud. Therefore, it should be grasped as needed when feeding. When the shoot length is 0.5-1 cm, the content of vitamin E is high, and it is suitable for broodstock prenatal breeding. For male fish, it can improve the quality of semen, and it can promote the development of eggs and increase the fertilization rate of eggs. When the buds are 2-3 cm long, they contain rich vitamin B, can promote appetite, help digestion, and are suitable for breeding adult fish. When the shoot length is 3-10 cm, vitamin A accounts for a large proportion and plays an important role in the growth and disease resistance of the fish. It is a good bait for breeding adult fish, broodstock and back broodstock. The use of grain bud fish is generally 3-4 kg of grain buds and 1 kg of fish. Grain buds can be used as feed directly feed fish, can also be used as vitamin additives in conjunction with other bait to improve the utilization of bait.

Second, the germination feed production method

The raw materials used as germinating feeds in production are seeds of barley cereals such as barley, oats, corn, and rice, of which the most common ones are wheat and wheat. The method of making sprouted feed is basically similar to that of raw bean sprouts and soaking seed germination, that is, the raw material seeds are screened and mixed, then put into warm water, washed, dried and put into water of 20-25 DEG C, and soaked with water, and then use gauze, Sprouts, etc., are packaged for germination, sprayed with warm water of about 30°C 4-6 times per day and night, and properly mixed. After 2-3 days, the raw seeds can be used to produce hair roots and germs to remove gauze and sacks. Each morning and evening, the clean warm water will be poured. After 3-5 days, shoots grow and can be fed as needed.

Third, the germination feed feeding technology

(1) Feeding objects: There are many kinds of fish that like to eat cereal germination feed, such as grass carp, carp, carp, etc. Therefore, these fish should be mainly fed. However, according to the findings of anatomy, bluegrass, clams, and squid also eat grain buds. (2) Feeding time: The bud feeding time is longer, generally from late April to early November. (3) Feeding "San Ding": In order to increase the utilization rate of grain bud feeding, it is necessary to grasp the fixed point, timing, and quantity when feeding. The daily feed amount is generally 5% of the total weight of the fish. (4) Reducing waste: To prevent feeding too little or too much, feed intake should be checked 4 hours after the start of grain feeding. If there are no remaining sprouts on the food market, the amount should be increased appropriately. If more grains are left on the food field, the amount should be reduced. If you only see a small amount of grain buds, it shows that the amount is basically appropriate.
