Problems solved by technology

[0006] At present, there are also large yellow croaker juvenile compound feeds with extruded pellets (hard pellets). During the production process of extruded pellets, due to high temperature and high pressure, it is impossible to add some microecological agents, which will affect the nutritional content and efficacy of the feed; at the same time, extruded pellets Pelletized feed is not conducive to the digestion of feed by the intestinal tract of juvenile large yellow croaker, thus affecting the feed conversion rate

Embodiment 1

[0077] Embodiment 1, the most basic content of each component of the present invention is as follows:

[0078] Fishmeal 50%;

[0079] Pregelatinized starch 21%;

[0080] Expanded soybeans 6%;

[0081] Fermented soybean meal 8%

[0082] Zein 6%;

[0083] Fish oil 2%;

[0084] Brewer's yeast 4%;

[0085] Minerals 2%;

[0086] Calcium dihydrogen phosphate 0.5%;

[0087] Choline Chloride 0.3%;

[0088] Multidimensional 0.2%.

[0089] According to the formula shown in the above table, the powdery crude feed was prepared, and after the powdery crude feed:water=5:2 weight ratio was made into soft pellet feed, the juvenile large yellow croaker was fed for 30 days. The juvenile fish that ingested the feed of this embodiment were active in feeding, the feed was stable in water, the fish body grew fast, and the economic benefit was better.

Embodiment 2

[0090] Embodiment 2, the content of each component after adding an appropriate amount of additives in the present invention is as follows:

[0091] Fishmeal 55%;

[0092] Pregelatinized starch 24%;

[0093] Expanded soybeans 6%;

[0094] Fermented soybean meal 3%;

[0095] Zein 6%;

[0096] Brewer's yeast 3%;

[0097] Minerals 1%;

[0098] Calcium dihydrogen phosphate 1%;

[0099] Choline Chloride 0.3%;

[0100] Multidimensional 0.2%;

[0101] Coated Vitamin C 0.1%;

[0102] Antioxidant 0.02%;

[0103] Attractant 0.2%;

[0104] Probiotics 0.18%.

[0105] According to the formula shown in the above table, the powdery crude feed was prepared, and after the powdery crude feed:water=5:2 weight ratio was made into soft pellet feed, the juvenile large yellow croaker was fed for 30 days. The juvenile fish that ingested the feed of this embodiment were active in feeding, the feed was stable in water, the fish body grew fast, and the economic benefit was better.

Embodiment 3

[0106] Embodiment 3: the content of each component after the present invention adds an appropriate amount of additives is as follows:

[0107] Fishmeal 48%;

[0108] Pregelatinized starch 21%;

[0109] Expanded soybeans 5%;

[0110] Fermented soybean meal 10%;

[0111] Zein 7%;

[0112] Fish oil 2%;

[0113] Brewer's yeast 3%;

[0114] Minerals 2%;

[0115] Calcium dihydrogen phosphate 1%;

[0116] Choline Chloride 0.3%;

[0117] Multidimensional 0.2%;

[0118] Coated Vitamin C 0.1%;

[0119] Antioxidant 0.02%;

[0120] Attractant 0.2%;

[0121] Probiotics 0.18%.

[0122] According to the formula shown in the above table, the powdery crude feed was prepared, and after the powdery crude feed:water=5:2 weight ratio was made into soft pellet feed, the juvenile large yellow croaker was fed for 30 days. The juvenile fish that ingested the feed of this embodiment were active in feeding, the stability of the feed was better in water, the fish body grew faster, and the ec...

Abstract

The invention discloses a soft pellet large yellow croaker and juvenile fish compound feed which comprises the following components: fish meal, pre-gelatinized starch, extruded soybeans, fermented soybean meal, precision corn protein, fish oil, beer yeast, mineral substances, monocalcium phosphate, choline chloride and multivitamin. Compared with traditional feed, the large yellow croaker and juvenile fish compound feed has the advantages of comprehensive nutrition, less pollution to culture water bodies and wide raw material source; and compared with the prior expanded pellet feed, the soft pellet compound feed has the advantages of high feed conversion rate, high digestibility and utilization rate, convenience in production, greenness and nuisanceless, and the like.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to the field of compound feed for juvenile large yellow croaker with soft particles. Background technique [0002] Scientific name of large yellow croaker: Pseudosciaena crocea . Also known as yellow croaker, red melon, cucumber, cucumber fish. [0003] Large yellow croaker is a highly migratory bottom fish. Due to overfishing, the resources of large yellow croaker have declined sharply, and artificial breeding is an inevitable choice. The artificial breeding technology of large yellow croaker began to be researched and made breakthroughs in the mid-1980s, and matured in the mid-1990s. In 2000, it formed a large-scale aquaculture industry. [0004] Many domestic feed companies have developed large yellow croaker compound feeds, but the popularity rate of large yellow croaker compound feeds is still very low. According to incomplete statistics, the current use rate of large yellow croaker...
