Feed for improving resistance of leeches

Abstract

The invention provides feed for improving the resistance of leeches. The feed is prepared from snail powder, freshwater mussel powder, dried blood, egg white, soybean meal, activin, rape seed cakes, olive oil, potassium sulphate, monopotassium phosphate, sodium citrate, calcium lactate, calcium hydrophosphate, magnesium sulfate, potassium chloride, lentinan, chitosan, milkvetch root powder, red-rooted salvia root powder, garlic powder, sorbitol, rhizoma atractylodis powder, elecampane powder, compound microbial bacteria, decavitamin and microelements. The feed for improving the resistance of the leeches is reasonable in component, rich and balanced in nutrition, good in palatability, rich in nutritional ingredient and comprehensive in nutrient element, the nutritional ingredients needed by growth of the leeches can be effectively supplemented, growth can be effectively promoted, the growth period of the leaches can be shortened, the breeding cost can be reduced, and economic benefits can be increased; the resistance of the leaches can be improved, the disease resistance can be improved, the diseases of the leaches can be reduced, the breeding cost can be reduced, and the economic benefits can be increased. In addition, the ingredients of the feed are free of pollution to water and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a feed for improving the resistance of leeches. Background technique [0002] Leeches, commonly known as leeches, have been recorded in "Shen Nong's Materia Medica", and have high medicinal value; they grow and reproduce in inland freshwater waters, and are traditional Chinese special medicinal aquatic animals. Used as medicine, it has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. In recent years, it has been newly discovered that leech preparations have special effects in the prevention and treatment of cardiovascular and cerebrovascular diseases and cancer. Historically, it was mainly caught by natural fishing. Due to the abuse of pesticides and chemical fertilizers in recent years, and the pollution of the environment by the "three wastes" of industry and agriculture, the wild natural resources have decli...

Problems solved by technology

At present, the existing common leech feed has single ingredients and lacks nutrients, which is not conducive to the growth and survival of leeches, and seriously affects the breeding benefits

In addition, the existing feeding feeds often lead to many leech diseases, low survival rate, slow growth rate, and the yield cannot be improved.

As for these common leech feeds, because they are taken from animals, they will more or less contain various parasites. If they are not handled properly, the leeches will affect their immunity after eating, and symptoms such as indigestion may occur. Affect its growth, seriously affect the survival rate of leech, seriously affect its medicinal value and economic value
