Special feed for metapenaeus ensis and processing method

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.
