How to increase fish growth rate

In the production of fish, only by improving the palatability, feeding intensity and feed utilization rate of fish bait can the production cost be reduced, and the economic income will increase. Here are four ways to increase the growth rate of fish. The addition of Artemisia argyi (Artemisia) is an extremely widespread plant that contains proteins, fats, vitamins and various essential amino acids and minerals. According to the test, adding 5% of the leaves to the feed can increase the weight gain rate of the first-instar carp of the pond feed by 15.4% to 22.4%. The growth rate of cockroaches and carp raised in the same pool also improves significantly. The weight gain of salmon can be increased by 14.5%. The added wolfberry contains 50.4% to 65.8% of crude protein, and has a complete range of amino acids, especially restricted amino acids, and is rich in vitamins. Due to the special smell of meat, it is easy to seduce and stimulate fish appetite. Adding 5% of wolfberry to compound feed can significantly reduce the feed coefficient of tilapia and increase the economic benefit by 74.5%. Adding 7.14% to 10% of dry cockroaches in combination feeding can increase the growth rate of cod by 63%. Vitamin C supplementation: When feeding squid, add 700 mg vitamin C per kilogram of feed. When feeding squid, add 500 mg vitamin C per kilogram of feed. The effect of weight gain is very significant. Adding 60 grams of vitamin C per kilogram of feed in carp can increase the daily weight gain of carp by 50% and save 29% of feed. Vitamin E: In fish feed, add vitamin E, so that the vitamin E content per kilogram of feed reaches 40 mg to 70 mg, which can increase the daily weight of fish by more than 10%. Add photosynthetic bacteria photosynthetic bacteria for fish, shrimp, rag, shellfish bait additives, the survival rate increased by 45% to 70%. For the freshwater fish seedlings, the survival rate of the seedlings increased by 6.53%, the growth rate increased by 15.2%, the weight gain rate increased by 25.2%, and the feed coefficient decreased by 25.96%. For salmon farming, the weight gain rate is increased by 10%, and disease resistance is improved. Its use is: 1 feed added. When photosynthetic bacteria are used as feed additives, the photosynthetic bacteria can be sprayed into the feed to mix well, and the amount of the bacteria liquid is 1% of the amount of feed to be fed. 2 water spray. Water spray is suitable for improving water quality, controlling fish diseases, and cultivating excellent algae. Choose sunny mornings or afternoons, dilute the photosynthetic bacteria with diluted pool water, and then spread the whole pool evenly. Use 5 to 10 ml of photosynthetic bacteria solution per cubic meter of water. The number of photosynthetic bacteria per ml of bacteria should be 10~ 1.5 billion. The number of photosynthetic bacteria is determined according to the water quality. The water quality can be applied once every 15 days. The water quality is relatively poor and the water quality is poor. Especially in the high-yielding pools in the rearing period, it should be applied every 7 to 10 days. The proliferation of photosynthetic bacteria should be used as soon as possible, storage at room temperature should not exceed 2 weeks, and the use of metal containers is prohibited.

Yaks are breeds of livestock on the plateau of China. Most live in the pollution-free and clean environment of the alpine region. Yak meat protein content, low fat content, rich in mineral elements, amino acid structure and human body closer to the ratio. The total amount of yaks in China accounts for 93% of the world total and is a renewable resource. It is a huge animal food resource that has not been developed and utilized. With the improvement of living standards, people's pursuit of diet has tended to be safe, green, nutritious and health-oriented, and the pollution-free and pure natural yak meat products have good market prospects by virtue of its advantages. Yak meat as raw materials processed all kinds of meat products more and more consumers. In particular, the use of modern technology ham meat type recombinant meat products, so that the high quality of yak meat has been fully exerted. In order to meet the growing need for convenient table-top food in the market, the company has developed a flavorful tableware that combines the characteristics of recombinant yak meat and spicy sauce, is more nutritious, versatile, convenient to eat and easy to transport and store. Yak meat sauce.
