Problems solved by technology

However, no matter feeding a single fresh or frozen low-value small miscellaneous fish (shrimp) or artificial high-fat diet, the black sea bream will cause fatty liver, high body fat and excessive fat deposition in other organs, which will affect commercial fish. the succulent

Embodiment 1

[0011] The components in the feed premix and the weight percentages of each component are 20% of carnitine, 40% of betaine, 30% of choline chloride and 10% of nanometer montmorillonite.

Embodiment 2

[0013] The components in the feed premix and the weight percentage of each component are 28% of carnitine, 36% of betaine, 20% of choline chloride and 16% of nanometer montmorillonite.

Embodiment 3

[0015] The components in the feed premix and the weight percentages of each component are 40% of carnitine, 20% of betaine, 20% of choline chloride and 20% of nanometer montmorillonite.

[0016] The preparation method of feed premix in above-mentioned 3 embodiments comprises the following steps:

[0017] Carnitine, betaine and choline chloride are weighed, pulverized into fine powder, and mixed uniformly in a mixer; then nanometer montmorillonite is added, and the feed premix is ​​obtained after further stirring uniformly in a mixer.

[0018] From July 17th to September 11th, 2006, a 56-day black sea bream (45.5±0.2g) breeding experiment was carried out at Xishan Island, the experimental base of Zhejiang Institute of Marine Fisheries. The feeds of the four groups in the test were formulated with the same quality and proportion of fish meal, soybean meal, starch, corn oil, fish oil, calcium dihydrogen phosphate, mineral additives and vitamin additions, so that the protein conte...

Abstract

The invention provides a lipoid transformation type feed premix for Sparus macrocephalus, wherein the constituents include (by weight percent) carnitine 20-40%, oxyneurine 20-40%, choline chloride 20-30% and montmorillonite 10-20%. The invention also provides the process for preparing the premix which comprises steps of weighing, disintegrating into fines, and mixing homogeneously. The premix can be used for increasing conversion rate of lipids in feed, promoting growth of Sparus macrocephalus and decreasing protein content in feed.

Description

technical field [0001] The invention relates to the technical field of fish feed, in particular to a high-efficiency lipid conversion type black sea bream feed premix. Background technique [0002] Black sea bream (Sparus macrocephalus) belongs to Perciformes, Bremidae, and genus. It is mainly distributed along the western coast of the Pacific Ocean. In my country, it is mainly distributed in the East China Sea, the Yellow Sea, the Bohai Sea coast, and the southern waters of the Taiwan Strait. It is one of the important economic fishes in our country. one. It is suitable for salt, wide in temperature, fast in growth rate, tender and delicious in meat, rich in nutritional value, and is popular in domestic and foreign (Japan and other places) markets, and has become one of the main fish in seawater farming. The feed major part of black sea bream culture still adopts and feeds single fresh or frozen low-value small miscellaneous fish (shrimp), and another method then adopts art...
