Problems solved by technology

[0004] However, many farmers blindly use antibiotics when the grouper has white stools and enteritis. While antibiotics kill harmful bacteria, they also destroy beneficial bacteria, destroying the protective barrier of beneficial bacteria, and their immune resistance will be weakened. become weaker

Embodiment 1

[0017] Follow the steps below to prepare grouper compound feed:

[0018] S1. Weigh the raw material components according to the following mass percentages and mix them evenly: 40% white fish meal, 6% squid meal, 10% Antarctic krill meal, 13% peeled soybean meal, 10% gluten powder, 10% high-gluten flour, Calcium dihydrogen phosphate 0.5%, fish oil 4%, soybean oil 2%, liquid phospholipid 2%, Bacillus 0.15%, glyceryl butyrate 0.35%, vitamin premix 1%, mineral premix 1%; The raw material components are all commercially available raw materials;

[0019] S2. After mixing all raw materials evenly, pass through a superfine pulverizer, so that all raw material components can pass through a 200-320 μm sieve;

[0020] S3. Transfer the material in the step S2 into the modem, feed in steam at 90-95°C for 5-7 minutes, and then carry out extrusion granulation at a temperature of 80-95°C;

[0021] S4. Dry the feed pellets at 85-90° C., then pack them into bags after cooling.

Abstract

The invention discloses an efficient environmentally-friendly compound feed for groupers. The compound feed comprises the following components in percentage by weight: 35-45% of white fish meal, 5-10% of squid powder, 6-14% of Antarctic krill powder, 10-20% of peeled soybean meal, 7-15% of vital wheat gluten, 6-12% of strong flour, 0.3-1% of calcium dihydrogen phosphate, 2-6% of fish oil, 1-3% of soybean oil, 1-3% of liquid phosphatide, 0.1-0.3% of bacillus, 0.2-0.5% of tributyrin, 1% of a vitamin premix, and 1% of a mineral substance premix. According to the compound feed disclosed by the invention, the health of intestinal tracts of the groupers can be improved, the damage of the intestinal tracts is avoided, the digestive absorption rate of the feed can be increased, the feed coefficient is reduced, and the discharge of nitrogen is reduced, so that the purpose that the compound feed is efficient and environmentally-friendly is achieved.

Description

technical field [0001] The invention relates to a grouper compound feed, which belongs to the technical field of fish feed, in particular to an efficient and environment-friendly grouper compound feed. Background technique [0002] The grouper is rich in nutrition, the meat is tender and delicious. The protein content in grouper meat is high. In addition to various amino acids necessary for the human body, it also contains inorganic salts, iron, calcium, phosphorus and vitamins and other nutrients necessary for the human body. Therefore, it is a fish with high economic value and belongs to The delicacies on the banquet are rare seafood products that sell well in Hong Kong, Macao and Taiwan. [0003] At present, some disease problems in grouper farming are caused by damage to the intestinal health of grouper, and some of them are caused by unreasonable feed preparation. Under normal circumstances, fish intestinal flora and intestinal mucosal immune system are in an ideal dy...
