Slow-sinking expanded feed for black carp and preparation method thereof

Abstract

The invention provides slow-sinking expanded feed for black carp and a preparation method thereof. The feed comprises fish meal, pork meal, protein powder of porcine corpuscle, soybean meal, peanut meal, cottonseed meal, rapeseed meal, corn DDGS (distillers' dried grains with soluble), rice bran, wheat, soybean oil, soybean phosphatide oil, monocalcium phosphate, wheat bran, bentonite, vitamin premix, vitamin C phosphate, allicin, trace element premix, choline chloride, an antioxidant, and a mildew inhibitor. The slow-sinking expanded feed for black carp and the preparation method thereof have the advantages that by using the specific preparation method, namely effective reasonable matching of feed materials, the feed features slow sinking, the problem that in the prior art, the slow-sinking expanded feed for black carp sinking fast is unable to be sufficiently eaten by the black carp and sinks to the bottom of a culture pond, thereby leading to feed waste is solved, feed material cost is further lowered, and feed coefficient is decreased.

Description

technical field [0001] The invention relates to the technical field of feed for aquaculture, in particular to a herring puffed feed, in particular to a slow-sinking puffed herring feed and a preparation method thereof. Background technique [0002] Herring belongs to Cyprinidae and Cyprinidae, and is mainly distributed in the middle and lower reaches of the Yangtze River. It is one of the "four major fish" in freshwater farming in my country and has important economic value. At present, herring farming is mainly concentrated in Xiantao, Hubei, Wuxi, Jiangsu, and Huzhou, Zhejiang, among which Wuxi and Huzhou account for about 15% of the national herring farming. Herring is on the market after the winter solstice, when the fish is of the best quality and delicious. In Hubei, Jiangsu, Zhejiang, and Anhui regions, herring is generally processed into salted fish, which is very popular among people. The larger the size of artificially farmed herring, the better the price. Durin...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the herring sinking extruded feed sinks too fast and cannot be fully ingested by the herring but sinks at the bottom of the breeding pond in the prior art, resulting in waste of feed, high cost of feed raw materials, and high feed coefficient. Provided is a herring slow-sinking extruded feed and a preparation method thereof. The feed not only has the characteristics of slow-sinking, but also reduces the cost of feed raw materials and the feed coefficient through effective and reasonable matching of feed materials and a specific preparation method.
