Problems solved by technology

However, substituting vegetable fat sources and animal fat sources for fish oil in actual production cannot meet the reasonable demands of juvenile large yellow croaker for n-3 and n-6 ​​fatty acids, and often leads to abnormal fat deposition in the liver of large yellow croaker , causing problems such as reduced metabolic capacity and decreased immunity of large yellow croaker

Embodiment 1

[0027] Take 35 parts of crushed raw fish meal, 28 parts of soybean meal, 23.8 parts of wheat flour, 1.875 parts of fish oil, 1.875 parts of linseed oil, 1.875 parts of soybean oil, 1.875 parts of lard, 1.5 parts of soybean lecithin, 2 parts of vitamin premix, mineral 2 parts of premix, 0.1 part of food attractant, 0.1 part of antifungal agent, 0.08 part of L-carnitine, passed through a 100-mesh sieve. Add the above-mentioned raw materials into the mixer step by step into the above-mentioned weighed components, mix evenly, mechanically extrude and granulate through a feed machine, dry, pack into a bag, and obtain the improvement of the invention to improve abnormal fat deposition in the liver of large yellow croaker artificial compound feed.

[0028] The place where the experiment was carried out was located in Ningde, Fujian. With reference to the basic formula of juvenile large yellow croaker, three kinds of experimental feeds with equal nitrogen and fat were prepared. The ba...

Embodiment 2

[0048] The lard in Example 1 was replaced with chicken oil, and the amount of carnitine added was 1000 mg / kg. Other experimental feed formulations and feeding methods were the same as in Embodiment 1. Prepare three kinds of experimental feeds such as nitrogen and other lipids, fish oil group basal feed (0% replacement group) and soybean oil, linseed oil and chicken oil equal amounts mixed to replace 75% fish oil basal feed (75% replacement group), at 75% replacement Add 1000mg / kg of L-carnitine in the group (75% replacement+1000mg / kg carnitine group).

[0049] As shown in Table 5, replacing fish oil with 75% mixed oil and 75% mixed oil plus 1000 mg / Kg carnitine had no significant effect on the survival rate of juvenile large yellow croaker. Compared with the large yellow croaker in the 0% replacement group, the addition of 1000mg / Kg carnitine significantly increased the weight gain rate and feed efficiency of large yellow croaker. Compared with the large yellow croaker in the...

Abstract

The invention relates to an artificial compound feed capable of improving exceptional fatty deposition of the liver of larimichthys crocea. The artificial compound feed comprises the following components of 30-40 parts of fish meal, 25-30 parts of soybean meal, 20-25 parts of wheat flour, 1.5-3 parts of fish oil, 1.5-3 parts of linseed oil, 1.5-3 parts of soybean oil, 1.5-3 parts of lard, 1.5-3 parts of chicken oil, 1-2 parts of soybean lecithin, 1-3 parts of a vitamin premix, 1-3 parts of a mineral premix, 0.08-0.12 part of a phagostimulant, 0.08-0.12 part of a mildewproof agent and 0.05-0.11part of carnitine. According to the artificial compound feed, the growth, the antioxidase vitality and the fat utilization efficiency of the young larimichthys crocea can be effectively promoted, theexceptional liver fat condition can be improved, the breeding benefits can be increased, the feed cost can be saved, and the breeding economic benefits are high.

Description

technical field [0001] The invention belongs to the technical field of fish feed preparation, and in particular relates to an artificial compound feed for juvenile large yellow croaker that promotes growth and reduces abnormal fat deposition. Background technique [0002] Large yellow croaker belongs to the order Perciformes, belongs to the family Scrotoaceae, and belongs to the genus Yellow croaker, also known as yellow croaker and large yellow flower. Large yellow croaker is a unique seawater economic fish in my country. According to statistics from the China Fisheries Yearbook, the output of large yellow croaker in 2016 was 165,500 tons. It ranks first in the production of marine fish farming. The increase in aquaculture production has led to a continuous increase in the demand for fish oil, and the limited resources of fish oil have also caused the price of fish oil to continue to rise. In production, low-cost vegetable oil or animal oil is often used to replace fish oil....
