Cherax quadricarinatus fish meal-free compound feed and preparation method thereof

Abstract

The invention discloses a cherax quadricarinatus compound feed and a preparation method thereof. The cherax quadricarinatus compound feed comprises 14%-23% of soybean meal, 8%-11% of peanut bran, 6%-10% of corn protein powder, 5%-9% of rapeseed meal, 5%-10% of cuttlefish powder, 4%-8% of blood powder, 4%-7% of shrimp shell powder, 3%-6% of beer yeast, 1%-3% of earthworm powder, 3%-6% of sucrose, 6%-9% of corn starch, 6%-9% of high gluten flour, 0.1%-0.2% of sodium chloride, 1.0%-2.0% of compound vitamin, 0.5%-1.5% of compound mineral substance, 0.5%-1.5% of choline chloride, 1.0%-2.0% of calcium dihydrogen phosphate, 0.2%-0.6% of lysine, 0.2%-0.8% of methionine, 0.9%-1.95% of sodium carboxymethyl cellulose, 1.0%-2.0% of immunopotentiator, 1.0%-3.0% of phagostimulant, 0.05%-0.1% of compound enzyme, 2.0%-3.0% of soybean oil and 2.0%-3.0% of peanut oil. Comprehensive and balanced nutrition can be achieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed, in particular to a fishmeal-free compound feed for red-clawed crayfish and a preparation method thereof. Background technique [0002] Commonly known as Australian freshwater lobster, red claw crayfish are native to streams in northern Australia and southern New Guinea. my country first carried out trial breeding in 1992, but due to the low emergence rate and high price of shrimp seedlings, its large-scale promotion and cultivation were restricted, and it gradually faded out of my country's aquaculture industry under the upsurge of prawn cultivation. In recent years, due to the frequent occurrence of various diseases of prawns and the low growth rate of prawns in the country, some farmers have begun to seek new promising species for prawn farming. As well as the high price, the aquaculture market has been re-entered. [0003] At present, the artificial breeding of red-clawed crayfish i...

AI Technical Summary

Problems solved by technology

[0003] At present, the artificial breeding of red-clawed crayfish is still in its infancy, and there is a lack of special artificial compound feed. Some farmers use pumpkin and other melons and fruits for feeding, which obviously lack nutrients, resulting in slow growth, long breeding cycle and low output; Farmers choose other shrimp compound feeds such as Penaeus vannamei and other shrimps, which are costly and obviously do not meet the nutritional and physiological needs of crayfish. The bait coefficient is high, resulting in waste; The more severe the situation, the more likely the aquatic animals are to be subjected to the stress of various toxic substances, resulting in slow growth, low yield, decreased immunity and disease resistance, and prone to disease outbreaks. Therefore, the compound feed used should be added with appropriate Immunity enhancer, improve the immunity and stress resistance of aquatic animals from the nutritional point of view, reduce the probability of disease occurrence, thereby reducing the use of drugs, gradually realize ecological farming, produce safe and high-quality aquatic products, protect the environment and aquatic products The healthy and sustainable development of the aquaculture industry is of great significance
