Embodiment 1

[0068] The compound feed was prepared according to the following method: raw materials were screened, various raw materials were pulverized and passed through a 40-mesh sieve, and the ingredients were formulated according to the formula number 1 shown in Table 5. After all the dry matter ingredients are fully mixed with a mixer, add the oil source, mix well, and then add an appropriate amount of water for thorough mixing. After mixing evenly, use a twin-screw extruder to make experimental feeds with a diameter of 1.5-2.5 mm, air-dry naturally at room temperature, then pack them in sealed plastic bags, and store them for later use.

[0069] Select 324 healthy and uniform juvenile Japanese yellow croakers (initial weight is about 7.2g / tail) for grouping, and put them into 18 cylindrical culture experiments (volume about 300L) on average, and weigh each barrel of fish separately. Weighing and counting, the final data was taken as its mean value, and there was no significant diffe...

Embodiment 2

[0075] Formula feed material by formula 2 shown in table 5.

[0076] Other operations are the same as in Example 1.

[0077] The variation situation of phosphorus in the breeding process of this embodiment is shown in Table 6.

[0078] See Table 7 for specific growth, feed utilization and biological index test results.

Embodiment 3

[0080] The feedstuffs were prepared according to formula 3 shown in Table 5.

[0081] Other operations are the same as in Example 1.

[0082] The variation situation of phosphorus in the breeding process of this embodiment is shown in Table 6.

[0083] See Table 7 for specific growth, feed utilization and biological index test results.

Abstract

The invention disclose a Japanese croaker compound feeding stuff, comprising the matters with the followings weight percentages: fish meal 20-35, bean pulp 40-60, fish oil 1.5-3.0, soybean oil 0.5-5.0, soybean lecithin 0.5-2.0, corn starch 0.1-15, antioxidant 0.5-1.0, adhesive agent 1.0-3.0, sinkaline 0.1-0.5, compound vitamin 1.0-2.5 and compound mineral salt 2.5-3.5. In the invention, according to the characteristic of the digestive physiology of Japanese croaker, high-biological-availability feeding stuff raw materials are used, thus meeting all nutrition needs of the Japanese croaker fed artificially. The invention has the advantages of promoting the rapid growth of the Japanese croaker, improving the digestibility of the Japanese croaker, reducing excretions, such as nitrogen, phosphorus, and the like, and being good for environment protection; besides, the raw materials used in the compound feeding stuff has stable sources and low cost, therefore, the compound feeding stuff is suitable for the intensive feeding of the Japanese croaker.

Description

technical field [0001] The invention relates to the field of aquatic animal feed, in particular to a compound feed for Japanese yellow croaker. Background technique [0002] Japanese yellow croaker (Nibea japonica) belongs to the order Perciformes, the family Scrotoaceae, and the genus Nibea japonica. Mainly distributed in the East China Sea and the southern coast of Japan. It has always been the main fishing target of traditional fishery. It has strong survival ability, wide temperature and wide salt, easy to breed, less disease, delicious meat and rich nutrition. It is a high-quality economic fish with high development value. Japan began artificial breeding in 1995, South Korea introduced the fish from Japan in 1991, carried out artificial breeding in 1998, and developed it as an excellent fish species. Since 2000, the Zhejiang Provincial Institute of Marine Fisheries has successfully introduced the fertilized eggs of Japanese croaker from Korea for three consecutive yea...
