Problems solved by technology

The Chinese patent with the patent publication number CN104431391A discloses a kind of artificial puffed feed for re-exportation of giant salamanders at the gill removal stage and its preparation method. The raw materials of the puffed feed are: fish meal, fermented soybean meal, broken yeast, shrimp shell powder, unfermented soybean meal, brown algae Glue, calcium chloride, calcium dihydrogen phosphate, a-starch, immune polysaccharide, citric acid, premix and fish oil. Although the extruded feed is rich in nutrition and the ratio is reasonable, the particle size and usage method of the feed are not disclosed
However, the larval stage of giant salamanders is immature, and diseases such as enteritis and abdominal distension are prone to occur. reduced survival rate

Abstract

The invention discloses a giant salamander larval turning feed and a preparation and use method thereof. The giant salamander larva turning feed comprises, by weight, 10-90% of powdery feed and 10-90%of minced fish, wherein the powdery feed mainly comprises, by weight, 20-40% of imported fish meal, 15-30% of soybean meal, 3-10% of rapeseed meal; 5-15% of meat and bone meal, 3-8% of beer yeast, 3-8% of squid paste, 10-20% of cassava powder, 1-3% of fish oil, 1-3% of soybean oil, 0.3-1.5% of betaine, 0.5-3.0% of calcium dihydrogen phosphate, 0.5-3.0% of composite premix and 0.5-3.0% of a functional additive. The larva turning feed can improve the weight gain rate of young salamanders and reduce the bait coefficient; the immunity and oxidation resistance of the young salamanders are enhanced, the intestinal microecological environment is improved, the morbidity is reduced, and the survival rate is improved; the larva turning feed has good stability and the water body is not easy to pollute.

Description

technical field [0001] The invention relates to a giant salamander feed, in particular to a re-export feed for giant salamander larvae and a preparation and use method thereof. Background technique [0002] Giant salamander, commonly known as giant salamander, has tender meat and unique taste. It has extremely high economic value, medicinal value and food value, which has promoted the rapid development of giant salamander breeding industry. [0003] At present, giant salamander farming mainly feeds on fresh fish and shrimps. This farming model is easily limited by the source and season of fresh bait; the bait coefficient of fresh bait is as high as 5-6, that is, 5-6 catties of bait needs to be fed Only the giant salamander can grow by 1 catties, and the cost of breeding is very high; fresh and live bait is easy to carry parasites and germs, which will cause the giant salamander to get sick. [0004] For this reason, there are more and more R&D and application of compound fee...
