Soft-shelled turtle compound feed and preparation method thereof

Abstract

The invention provides a soft-shelled turtle compound feed and a preparation method thereof. The feed comprises fish meal, alpha-starch, fermented soybean meal, fish oil, yeast, methionine, lysine, milk powder, yolk powder, a compound mineral premix for a soft-shelled turtle feed, a compound vitamin premix for the soft-shelled turtle feed, monocalcium phosphate, an enzyme preparation, and a Chinese herbal medicine additive. The preparation process comprises the following steps: feeding, preliminary cleaning, primary mixing, iron removal, crushing, secondary mixing and packaging. The feed formula is scientific and reasonable in collocation, the disease resistance of soft-shelled turtles is improved, feed raw materials with high digestibility are selected; the feed conversion rate is improved, the emission of pollutants such as nitrogen and phosphorus is reduced; the soft-shelled turtle feed reduces water body pollution, reduces diseases of soft-shelled turtles, reduces drug use, finallymeets the requirements of ecological breeding, improves the absorption and utilization rate of the feed, can meet the nutritional requirements of the soft-shelled turtles, reduces the breeding cost,reduces the water body pollution, and the method is scientific and reasonable, and has remarkable economic benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of feed, and more specifically relates to a compound feed for soft-shelled turtle seedlings and a preparation method thereof. Background technique [0002] Soft-shelled turtles are commonly known as yuan fish, turtle fish, water fish, bastard and so on. Breeding can be divided into two types: natural ecological farming mode and constant temperature technology factory farming mode. The natural ecological breeding mode without heating in winter takes 2 to 4 years to grow into a commercial size (about 1.2 catties / fish), but the soft-shelled turtles raised in the heated pond in winter can be moved to the open-air pond for natural breeding when the water temperature rises in April. Ecological farming. At present, the soft-shelled turtles in the industrial culture of constant temperature technology account for about 65% of the total production of soft-shelled turtles in my country. It is necessary to keep the bre...

Problems solved by technology

However, high-input, high-yield, and high-tech factory farming of soft-shelled turtles has certain risks. If the daily management is not in place, and the selection of compound feed is improper, it is likely to cause frequent soft-shelled turtle diseases and high mortality.

In addition, after many soft-shelled turtles are fed with feed, the soft-shelled turtles do not like to eat, there are many residues, the conversion rate after feeding is low, and a large amount of nitrogen and phosphorus are emitted, which causes serious pollution of the breeding water body, causing the prevalence of soft-shelled turtle diseases and serious death

Some farmers use a large amount of drugs for unscientific disease prevention and control. As a result, drug residues in commercial soft-shelled turtles seriously exceed the standard, endangering the health of consumers. In recent years, there have been frequent incidents of toxic aquatic products in my country, all of which are caused by the indiscriminate use of drugs
