Embodiment 1
[0019] A special feed for basilisk shrimp in this embodiment, the raw materials include the following components, in parts by weight of each component: 25 parts of fish meal, 11 parts of cornstarch, 12 parts of wheat flour, 8 parts of bone meal, 5 parts of blood meal, and seaweed meal 8 parts, 6 parts of fish oil, 0.5 parts of lysine, 0.4 parts of methionine, 0.4 parts of protease, 1.5 parts of multivitamins, and 2 parts of multivitamins.
[0020] The processing method of the above-mentioned special-purpose feed for shrimps comprises the following steps:
[0021] 1) Weighing various raw materials;
[0022] 2) Mixing: The weighed raw materials are mixed, and the mixing time is 60-80 seconds;
[0023] 3) Pulverization: After mixing, the material is pulverized, and the fineness is required to retain less than 5% of the particle weight of the ?1.5mm sieve;
[0024] 4) Tempering and aging: the tempering time is 1.5-3.0min, the tempering temperature is 80-100℃, and the tempering m...
Embodiment 2
[0030] The special feed for shrimps in this embodiment differs from that in Example 1 in that the raw materials include the following components, which are in parts by weight of each component: 20 parts of fish meal, 8 parts of cornstarch, 10 parts of wheat flour, 5 parts of bone meal, 3 parts of blood meal, 5 parts of seaweed powder, 3 parts of fish oil, 0.3 part of lysine, 0.3 part of methionine, 0.2 part of protease, 0.5 part of multivitamin, 0.8 part of multivitamin.
Embodiment 3
[0032] The special feed for shrimps in this embodiment differs from that in Example 1 in that the raw materials include the following components, in parts by weight of each component: 30 parts of fish meal, 15 parts of cornstarch, 15 parts of wheat flour, 10 parts of bone meal, 6 parts of blood meal, 10 parts of seaweed powder, 8 parts of fish oil, 0.7 parts of lysine, 0.5 parts of methionine, 0.7 parts of protease, 2.5 parts of multivitamins, and 3.0 parts of multivitamins.

Abstract
The invention relates to a special feed for metapenaeus ensis and a processing method, and belongs to the technical field of processing of aquaculture feeds. Raw materials of the special feed comprise the following components in parts by weight: 20-30 parts of fish meal, 8-15 parts of corn starch, 10-15 parts of wheat flour, 5-10 parts of bone meal, 3-6 parts of blood powder, 5-10 parts of dried marine algae powder, 3-8 parts of fish oil, 0.3-0.7 part of lysine, 0.3-0.5 part of methionine, 0.2-0.7 part of protease, 0.5-2.5 parts of complex vitamins and 0.8-3.0 parts of composite mineral substances. The processing method comprises the following steps of (1) weighing the raw materials; (2) mixing the weighed raw materials; (3) pulverizing the mixed materials; (4) quenching and tempering the pulverized materials, and ageing the quenched and tempered materials; (6) performing granulation; (7) drying granules; (8) cooling the dried granules; and (9) crumbling the cooled granules with a roller type granule crumbler. According to the formula of the special feed disclosed by the invention, in accordance with the growth characteristics of the metapenaeus ensis, an appropriate amount of the bone meal and an appropriate amount of the blood powder are added to the formula, so that calcium and heme desired for the metapenaeus ensis are increased, and the nutrition in the feed can meet the growth need of the metapenaeus ensis; the lysine and the methionine are added, so that the utilization rate of plant peptide hydrolysates is increased, the nutritional absorption is promoted, the digestibility of the raw materials is improved, besides, the taste is strengthened, the lower feed coefficient of the metapenaeus ensis is guaranteed, and the specific growth rate is high.
Description
technical field [0001] The invention relates to a special feed for basilisk shrimp and a processing method thereof, and belongs to the technical field of aquaculture feed processing. Background technique [0002] Jiwei shrimp shell is thin and fat, the meat is delicious and tender, and rich in nutrition. It has a wide range of adaptability to salinity and is suitable for breeding in freshwater ponds. It is a promising new species of sea shrimp. In recent years, Jiwei shrimp farming has developed rapidly. Due to its miscellaneous food habits, tender and delicious meat, and high economic value, the prospects and market of this shrimp farming have always been optimistic, and it is a new breeding species with great development potential. And the bait that puts in of cultivating base enclosure shrimp is directly related to the growth of shrimp body, also lacks special-purpose base enclosure shrimp special-purpose compound feed on the market at present. Contents of the inventio...
